Re:  Petition of Vantage Aerial Media for an Exemption Pursuant to Section 333 of the FAA

Modernization and Reform Act of 2012 to Operate an Small Unmanned Aircraft System.

Dear	Sir	or	Madam:	

Pursuant	to	Section	333	of	the	FAA	Modernization	and	Reform		Act	of	2012		(the	Reform	Act)	

and	14	C.F.R.	Part	11,	Vantage	Aerial	Media	hereby	applies	for	an	exemption	from	the	listed	

Federal	Aviation	Regulations	(FARs)	to	allow	commercial	operation	of	small	unmanned	aerial	

systems	(sUAS),	for	aerial	imaging	for	safety	and	monitoring	of	secured	and	controlled	project	

sites,	so	long	as	such	operations	are	conducted	within	and	under	the	conditions	outlined	herein	

or	as	may	be	established	by	the	FAA	as	required	by	Section	333.

This	exemption	is	in	accordance	with	protocols	outlined	in	this	petition	for	exemption	and	

incorporates	the	material	contained	in	the	following:	

 Appendix	A:	Vantage	Aerial	Media	sUAS	Operation,	Inspections,	and	Maintenance	Manual		

 Appendix	B:	Vantage	Aerial	Media	sUAS	Pilot	Operating	Handbook	

 Appendix	C:	Vantage	Aerial	Media	sUAS	Training	Manual	

 Appendix	D:	DJI	S1000	User	Manual	

 Appendix	E:	A2	Flight	Control	System	User	Manual		

As	described	more	fully	below,	the	requested	exemption	would	permit	the	operation	of	sUAS	

under	controlled	conditions	in	airspace	that	is	1)	limited	2)	predetermined	3)	controlled	as	to	

access	and	4)	would	provide	safety	enhancements.		Approval	of	this	exemption	would	therefore	

create	no	safety	concerns	regarding	national	airspace	and	would	fulfill	the	Secretary	of	

Transportation's	(the	FAA	Administrator's)	responsibilities	to	"...establish	requirements	for	the	

safe	operation	of	such	aircraft	systems	in	the	national	airspace	system."	Section	333(c)	of	the	

Reform	Act.

STATUTORY AUTHORITY FOR EXEMPTIONS

The	Federal	Aviation	Act	expressly	grants	the	FAA	the	authority	to	issue	exemptions.		This	

statutory	authority	by	its	terms	includes	exempting	civil	aircraft,	as	the	term	is	defined	under	

§40101	of	the	Act,	that	includes	sUASs,	from	the	requirement	that	all	civil	aircraft	must	have	a	

current	airworthiness	certificate.	

The	Administrator	 may	grant	 an	exemption	 from	a	requirement	 of	a	regulation	 prescribed	

under	 subsection	 (a)	or	(b)	of	this	section	 or	any	sections	 44702‐44716	of	this	 title	if	the	

Administrator	 finds	 the	exemption	in	the	public	 interest.	 49	U.S.C.	§44701(f)	 See also 49	USC	

§44711(a);	49	USC	§44704;	14	CFR	 §91.203	 (a)	(1).	

Section	333(b)	of	the	Reform	Act	assists	the	Secretary	in	determining	whether	sUAS	may	

operate	in	the	National	Airspace	System	(NAS)	without	creating	a	hazard	to	the	user,	the	

public,	or	a	threat	to	national	security.		In	making	this	determination,	the	Secretary	must	

consider:	

 The	sUAS's	size,	weight,	speed,	and	operational	capability;	

 Operation	of	the	sUAS	in	close	proximity	to	airports	and	populated	areas;	and	

 Operation	of	the	sUAS	within	visual	line	of	sight	of	the	operator.	

Reform	Act	§	333	(a).		Lastly,	if	the	Secretary	determines	that	such	vehicles	"may	operate	safely	

in	the	national	airspace	system,	the	Secretary	shall	establish	requirements	for	the	safe	

operation	of	such	aircraft	in	the	national	airspace	system."		Vantage	Aerial	Media	interprets	this	

provision	to	place	the	duty	on	the	Administrator	to	not	only	process	applications	for	
exemptions	under	Section	333,	but	for	the	Administrator	to	craft	conditions	for	the	safe	

operation	of	the	sUAS,	if	it	should	be	determined	that	the	conditions	set	forth	herein	do	not	

fulfill	the	statutory	requirements	for	approval.	

Vantage	Aerial	Media’s	sUAS	is	a	multirotor	vehicle,	 weighing	 55	or	fewer	lbs.	including	

payload.	 The	sUAS	operates,	 under	 normal	 conditions,	 at	a	speed	 of	no	more	 than	50	knots	

and	has	 the	capability	to	hover,	 and	move	 in	the	vertical	and	horizontal	 plane	

simultaneously.	 The	sUAS	will	operate	 only	in	the	Pilot’s	visual	line	of	sight	 a t 	 a l l 	 t i m e s 	

a n d 	 will	operate	 only	within	 the	sterile	 area	described	 in	the	Appendices .		 Such	

operations	 will	insure	 that	 the	sUAS	will	"not	create	 a	hazard	 to	users	 of	the	national	

airspace	 system	 or	the	public."	

Given	 the	small	size	of	the	sUAS	and	the	restricted	 and	sterile environment	within	which	 it	

will	operate,	Vantage	Aerial	Media	 falls	 squarely	 within	that	zone	 of	safety	(an	equivalent	

level	 of	safety)	in	which	Congress	 envisioned	 that	the	FAA	must,	 by	exemption,	 allow	

commercial	operations	 of	sUAS	to	commence	 immediately.	 	 Also	due	to	the	small	size	 of	

the	sUAS	and	the	low	al ti tudes	and	res tric ted	areas	in	which	 the	sUAS	will	

opera te,	approval	 of	the	application	presents	 no	national	 security	issue.	 	

Given	 the	clear	 direction	in	Section	 333	 of	the	Reform	 Act,	the	authority	 contained	 in	the	

Federal	 Aviation	Act,	as	amended;	the	strong	equivalent	level	of	safety	 surrounding	the	

proposed	 operations,	 and	the	 significant	public	benefit,	including	enhanced	safety,	the	grant	

of	the	requested	exemption	is	in	the	public	interest.		Accordingly,	Vantage	Aerial	Media	

respectfully	requests	that	the	FAA	grant	the	requested	exemption	without	delay.

PUBLIC INTEREST

This	exemption	application	is	expressly	submitted	to	fulfill	Congress'	goal	in	passing	Section	

333(a)	through	(c)	of	the	Reform	Act.		This	law	directs	the	Secretary	of	Transportation	to	

consider	whether	certain	unmanned	aircraft	systems	may	operate	safely	in	the	NAS	before	

completion	of	the	rulemaking	required	under	Section	332	of	the	Reform	Act.		By	granting	an	

exemption	the	FAA	will	fulfill	Congress’s	intent	of	allowing	UAS	to	operate	with	significant	

safety	precautions	in	low	risk	environments.	

The	use	of	sUAS	on	project	sites	can	significantly	reduce	the	risk	to	workers	of	falls	while	

inspecting,	surveying,	or	monitoring	site	construction	progress.		sUAS	can	inspect,	photograph,	

and	collect	data	in	hard	to	reach	areas	that	otherwise	would	require	worker	inspection.		Falls	

are	a	leading	source	of	workplace	fatality	and	injury	(www.osha.gov).		With	the	use	of	the	

proposed	sUAS	Vantage	Aerial	Media	could	minimize	the	need	to	expose	industry	professionals	

to	high	fall	risk	activities,	which	in	turn	could	save	lives.	

Additionally,	sUAS	could	replace	the	use	of	helicopters	and	small	aircraft	to	monitor	sites.		The	

sUAS	Vantage	Aerial	Media	proposes	to	fly	in	this	application	is	less	than	55	lbs.	and	carries	no	

combustible	material	on	board,	as	opposed	to	the	much	larger	conventionally	powered	small	
aircraft.		Shifting	to	sUAS	from	helicopters	presents	a	marked	safety	increase	for	workers	and	

the	public.	

Lastly,	sUAS	reduce	the	environmental	impact	by	dramatically	decreasing	the	energy	used	for	

aerial	imaging	and	data	collection	over	a	project	site.		The	proposed	sUAS	uses	rechargeable	

lithium	ion	batteries,	as	opposed	to	fossil	fuels	burned	in	operation	of	much	heavier	small	

aircraft.	

EQUIVALENT LEVEL OF SAFETY

Vantage	Aerial	Media	proposes	that	the	exemption	requested	herein	apply	to	sUAS	that	have	

the	characteristics	and	that	operate	with	the	limitations	listed	herein.	These	limitations	provide	

for	an	exceptional	level	of	safety	to	operations.	These	limitations	and	conditions	to	which	

Vantage	Aerial	Media	agrees	to	be	bound	when	conducting	commercial	operations	under	an	

FAA	issued	exemption	include:	

1. The	sUAS	will	weigh	less	than	55	lbs.	

2. Flights	will	be	operated	within	line	of	sight	of	Pilot	in	Command	or	Visual	

Observer.	

3. Maximum	total	flight	time	for	each	operational	flight	will	be	20	minutes.		Flights	will	be	

terminated	at	20%	battery	power	reserve	should	that	occur	prior	to	the	20	minute	limit.	

4. Flights	will	normally	be	operated	at	an	altitude	below	200	feet	AGL,	never	exceeding	

400	feet	AGL	

5. The	sUAS	pilot	will	be	trained	and	certified	in	the	proper	safety	and	operations	of	the	

sUAS.	

6. The	sUAS	will	only	operate	within	a	controlled	area	as	defined	in	the	Appendices.	

7. The	sUAS	pilot	will	post	advisory	notices	where	people	are	located	around	the	

controlled	area.	

8. A	briefing	will	be	conducted	in	regard	to	the	planned	sUAS	operations	prior	to	each	

day’s	production	activities.		It	will	be	mandatory	that	all	personnel	who	will	be	

performing	duties	within	the	boundaries	of	the	safety	perimeter	be	present	for	this	

briefing.	

9. All	onsite	personnel	will	consent	to	the	sUAS	flyover	by	waiver,	and	the	operator	will	

obtain	additional	verbal	or	written	consent	of	all	persons	who	will	be	allowed	within	

100	feet	of	the	flight	operation.	

10. Operator	will	have	been	trained	in	operation	of	sUAS	generally	and	will	have	received	

up‐to‐date	information	on	the	particular	sUAS	to	be	operated	as	required	by	the	

Appendices.	

11. Written	and/or	oral	permission	from	the	relevant	property	holders	will	be	obtained.	

12. If	the	sUAS	loses	communications	or	loses	its	GPS	signal,	the	UAS	will	have	the	capability	

to	return	to	a	pre‐determined	location	within	the	Security	Perimeter	and	land.	

13. The	sUAS	will	have	the	capability	to	abort	a	flight	in	case	of	unpredicted	obstacles	or	

emergencies.	
DESCRIPTION OF SPECIFIC REGULATIONS

14 C.F.R. Part 21, Subpart H: Airworthiness Certificates & 14 C.F.R. §91.203 (a) (1)

Subpart	H,	entitled	Airworthiness	Certificates,	establishes	the	procedural	requirements	for	the	

issuance	of	airworthiness	certificates	as	required	by	FAR	§91.203	(a)	(1).	

Given	the	size	and	limited	operating	area	associated	with	the	sUAS	to	be	utilized	by	Vantage	

Aerial	Media,	an	exemption	from	Part	21	Subpart	H	meets	the	requirements	of	an	equivalent	

level	of	safety	under	Part	11	and	Section	333	of	the	Reform	Act.		The	Federal	Aviation	Act	(49	

U.S.C.	§44701	(f))	and	Section	333	of	the	Reform	Act	both	authorize	the	FAA	to	exempt	aircraft	

from	the	requirement	for	an	airworthiness	certificate,	upon	consideration	of	the	size,	weight,	

speed,	operational	capability,	and	proximity	to	airports	and	populated	areas	of	the	particular	

sUAS.		In	all	cases,	an	analysis	of	these	criteria	demonstrates	that	the	sUAS	operated	without	an	

airworthiness	certificate,	in	the	restricted	environment		and	under	the	conditions	proposed	will	

be	at	least	as	safe,	or	safer,	than	a	conventional	aircraft	(fixed	wing	or	rotorcraft)	operating	with	

an	airworthiness	certificate	without	the	restrictions	and	conditions	proposed.	

The	proposed	sUAS	to	be	operated	is	less	than	55	lbs.	fully	loaded,	carries	neither	a	pilot	nor	

passenger,	carries	no	explosive	materials	or	flammable	liquid	fuels,	and	operates	exclusively	

within	a	controlled	area	as	set	out	in	the	Appendices.		Unlike	other	civil	aircraft,	operations	

under	this	exemption	will	be	tightly	controlled	and	monitored	by	the	sUAS	pilot,	pursuant	to	the	

requirements	set	out	in	the	Appendices.		Lastly,	application	of	these	same	criteria	demonstrates	

that	there	is	no	credible	threat	to	national	security	posed	by	the	sUAS,	due	to	its	size,	speed	of	

operation,	location	of	operation,	lack	of	explosive	materials	or	flammable	liquid	fuels,	and	

inability	to	carry	a	substantial	external	load.	

14 C.F.R. Part 27: Airworthiness Standards: Normal Category Rotorcraft

This	regulation	sets	forth	the	procedural	requirements	for	airworthiness	certification	of	normal	

category	rotorcraft.		To	the	extend	the	S1000	would	otherwise	require	certification	under	Part	

27,	Vantage	Aerial	Media	seeks	an	exemption	from	Part	27’s	airworthiness	standards	for	the	

same	reasons	identified	in	the	request	for	exemption	from	14	C.F.R.	Part	21,	Subpart	H.	

14 C.F.R. § 45.23 (b): Marking of the Aircraft

The	regulation	requires	when	marks	include	only	the	Roman	capital	letter	"N"	and	the	

registration	number	is	displayed	on	limited,	restricted	or	light‐sport	category	aircraft	or	

experimental	or	provisionally	certificated	aircraft,	the	operator	must	also	display	on	that	

aircraft	near	each	entrance	to	the	cabin,	cockpit,	or	pilot	station,	in	letters	not	less	than	2	inches	

nor	more	than	6	inches	high,	the	words	"limited,"	"restricted,"	"light‐sport,"	"experimental,"	or	

"provisional,"	as	applicable.	

Even	though	the	sUAS	will	have	no	airworthiness	certificate,	an	exemption	may	be	needed	as	

the	UAS	will	have	no	entrance	to	the	cabin,	cockpit	or	pilot	station	on	which	the	word	

"Experimental"	can	be	placed.	

Given	the	size	of	the	sUAS,	two‐inch	lettering	will	be	impossible.		The	word	"Experimental"	will	

be	placed	on	the	fuselage	in	compliance	with	§45.29	(f).		The	equivalent	level	of	safety	will	be	
provided	by	having	the	sUAS	marked	on	its	fuselage	as	required	by	§45.29	(f)	where	the	

operator	working	with	the	sUAS	will	see	the	identification	of	the	sUAS	as	"Experimental."	The	

FAA	has	issued	the	following	exemptions	to	this	regulation	to	Exemptions	Nos.	10700,	8738,	

10167	and	10167A.	

14 CFR 61.113(a) & (b): Private Pilot Privileges and Limitations: Pilot in Command

Sections	61.113	(a)	&	(b)	limit	private	pilots	to	non‐commercial	operation.		Because	the	sUAS	

will	not	carry	a	pilot	or	passengers,	the	proposed	operations	can	achieve	the	equivalent	level	of	

safety	of	current	operations	by	requiring	the	Pilot	operating	the	aircraft	to	have	completed	a	

sUAS	flight	training	course	as	detailed	in	the	Appendices.		Unlike	a	conventional	aircraft	that	

carries	the	pilot	and	passengers,	the	sUAS	is	remotely	controlled	with	no	living	thing	or	cargo	

on	board.		Vantage	Aerial	Media’s	sUAS	can	also	be	operated	by	an	autopilot,	which	greatly	

reduces	the	danger	of	human	error.		The	area	of	operation	is	controlled	and	restricted,	and	all	

flights	are	planned	and	coordinated	in	advance	as	set	forth	in	the	Appendices.	

The	sUAS	to	be	operated	hereunder	is	less	than	55	lbs.	fully	loaded,	carries	neither	a	pilot	nor	

passenger,	carries	no	explosive	materials	or	flammable	liquid	fuels,	and	operates	exclusively	

within	a	secured	area	as	set	out	in	the	Appendices.		Like	other	civil	aircraft,	operations	under	

this	exemption	will	be	tightly	controlled	and	monitored	by	the	operator	and	in	compliance	with	

local	public	safety	requirements.	

The	risks	associated	with	the	operation	of	the	sUAS	are	therefore	diminished	from	the	level	of	

risk	associated	with	commercial	operations	contemplated	by	Part	61	when	drafted,	and	

allowing	operations	of	the	sUAS	as	requested	with	a	Pilot	who	has	met	the	minimum	

requirements	stated	in	the	Appendices	and	achieves	the	level	of	safety	contemplated	by	14	

C.F.R.	§	61.113	(a)	&	(b).	

14 C.F.R. §91.7(a): Civil Aircraft Airworthiness

The	regulation	requires	that	no	person	may	operate	a	civil	aircraft	unless	it	is	in	airworthy	

condition.	As	there	will	be	no	airworthiness	certificate	issued	for	the	aircraft,	should	this	

exemption	be	granted,	no	FAA	regulatory	standard	will	exist	for	determining	airworthiness.	

Given	the	size	of	the	aircraft	and	the	requirements	contained	in	the	Appendices	for	

maintenance	and	use	of	safety	check	lists	prior	to	each	flight,	an	equivalent	level	of	safety	will	

be	provided.	

14 CFR 91.9(b)(2): Civil Aircraft Flight Manual in the Aircraft

Section	91.9	(b)	(2)	provides:	

No	person	may	operate	a	U.S.‐registered	civil	aircraft	...	

(2)		For	which	an	Airplane	or	Rotorcraft	Flight	Manual	is	not	required	by	§21.5	of	this	chapter,	

unless	there	is	available	in	the	aircraft	a	current	approved	Airplane	or	Rotorcraft	Flight	Manual,	

approved	manual	material,	markings,	and	placards,	or	any	combination	thereof.	

The	sUAS,	given	its	size	and	configuration	has	no	ability	or	place	to	carry	such	a	flight	manual	

on	the	aircraft,	not	only	because	there	is	no	pilot	on	board,	but	because	there	is	no	room	or	

capacity	to	carry	such	an	item	on	the	aircraft.	
The	equivalent	level	of	safety	will	be	maintained	by	keeping	the	flight	manual	at	the	ground	

control	point	where	the	operator	flying	the	sUAS	will	have	immediate	access	to	it.		The	FAA	has	

issued	the	following	exemptions	to	this	regulation:	Exemption	Nos.	8607,	8737,	8738,	9299,	

9299A,	9565,	95658,	10167,	10167A,	10602,	32827,	and	10700.

14 CFR 91.103: Preflight Action

This	regulation	requires	each	operator	to	take	certain	actions	before	flight	to	insure	the	safety	

of	flight.		As	FAA	approved	rotorcraft	flight	manuals	will	not	be	provided	for	the	aircraft	an	

exemption	will	be	needed.		An	equivalent	level	of	safety	will	be	provided	as	set	forth	in	the	

Appendices.		The	operator	will	take	all	actions	including	reviewing	weather,	flight	battery	

requirements,	landing	and	takeoff	distances	and	aircraft	performance	data	before	initiation	of	

flight.	

14 CFR 91.109: Flight Instruction

Section	91.109	provides	that	no	person	may	operate	a	civil	aircraft	(except	a	manned	free	

balloon)	that	is	being	used	for	flight	instruction	unless	that	aircraft	has	fully	functioning	dual	

controls.	

sUAS	and	remotely	control	piloted	aircraft,	by	their	design	do	not	have	fully	functional	dual	

controls.		Flight	is	accomplished	through	the	use	of	a	control	box	that	communicates	with	the	

aircraft	via	radio	communications.		The	FAA	has	approved	exemptions	for	flight	training	

without	fully	functional	dual	controls	for	a	number	of	aircraft	and	for	flight	instruction	in	

experimental	aircraft.		See	Exemption	Nos.5778K	&	9862A.		The	equivalent	level	of	safety	

provided	by	the	fact	that	neither	a	pilot	nor	passengers	will	be	carried	in	the	aircraft	and	by	the	

size	and	speed	of	the	aircraft.	

14 CFR 91.119: Minimum Safe Altitudes

Section	91.119	establishes	safe	altitudes	for	operation	of	civil	aircraft.	Section	91.119	(d)	allows	

helicopters	to	be	operated	at	less	than	the	minimums	prescribed,	provided	the	person	

operating	the	helicopter	complies	with	any	route	or	altitudes	prescribed	for	helicopters	by	the	

FAA.	

As	this	exemption	is	for	a	sUAS	that	is	a	helicopter	and	the	exemption	requests	authority	to	

operate	at	altitudes	up	to	400	AGL,	an	exemption	may	be	needed	to	allow	such	operations.		As	

set	forth	herein	the	sUAS	will	never	operate	at	higher	than	400	AGL.	

The	equivalent	level	of	safety	will	be	achieved	given	the	size,	weight,	speed	of	the	sUAS	as	well	

as	the	location	where	it	is	operated.		In	addition,	the	low‐altitude	operations	of	the	sUAS	will	

ensure	separation	between	these	sUAS	operations	and	the	operations	of	conventional	aircraft	

that	must	comply	with	Section	91.119.	

14 CFR 91.121: Altimeter Settings

This	regulation	requires	each	person	operating	an	aircraft	to	maintain	cruising	altitude	by	

reference	to	an	altimeter	that	is	set	"...	to	the	elevation	of	the	departure	airport	or	an	

appropriate	altimeter	setting	available	before	departure."		As	the	sUAS	may	not	have	a	
barometric	altimeter,	but	instead	a	GPS	altitude	read	out,	an	exemption	may	be	needed.		An	

equivalent	level	of	safety	will	be	achieved	by	the	operator,	pursuant	to	the	Appendices,	

confirming	the	altitude	of	the	launch	site	shown	on	the	GPS	altitude	indicator	before	flight.	

14 CFR 91.151(a): Fuel Requirement for Flight in VFR Conditions

Section	91.151	(a)	prohibits	an	individual	from	beginning	"a	flight	in	an	airplane	under	VFR	

conditions	unless	(considering	wind	and	forecast	weather	conditions)	there	is	enough	fuel	to	fly	

to	the	first	point	of	intended	landing,	and,	assuming	normal	cruising	speed	‐	(1)	During	the	day,	

to	fly	after	that	for	at	least	30	minutes;	or	(2)	At	night,	to	fly	after	that	for	at	least	45	minutes."	

Given	the	technological	limitations	on	the	sUAS	battery	power	means	that	no	meaningful	flight	

operations	can	be	conducted	while	still	maintaining	a	30	minute	reserve.		The	aircraft	is	battery	

powered	with	a	maximum	flight	time	of	30	minutes.		Vantage	Aerial	Media	proposes	that	the	

maximum	flight	time	for	each	operational	flight	will	be	20	minutes.		The	aircraft	will	be	safely	

landed	with	no	less	than	the	greater	of	(a)	20%	battery	life	remaining	or	(b)	five	minutes	of	

flight	time	remaining.	

Applicant	believes	that	an	exemption	from	14	CFR	§91.151(a)	falls	within	the	scope	of	prior	

exemptions.	See	Exemption	10673	(allowing	Lockheed	Martin	Corporation	to	operate	without	

compliance	with	FAR	91.151	(a)).	Operating	the	small	UAS,	in	a	tightly	controlled	area,	with	less	

than	30	minutes	of	reserve	fuel,	does	not	create	the	type	of	risks	that	Section	91.151	(a)	was	

intended	to	alleviate	given	the	size	and	speed	of	the	sUAS.	

The	FAA	has	stated	that	an	equivalent	level	of	safety	is	provided	if	the	sUAS	flight	is	conducted	

under	daytime	VFR	flight	conditions	using	visual	line	of	sight	(VLOS),	and	terminated	with	at	

least	25%	reserve	battery	power	still	available.		See	Grant	of	Exemption	No.	11062,	p.	21‐22.		

The	Appendices	requires	an	equivalent	level	of	safety	by	safely	landing	with	no	less	than	the	

greater	of	(a)	20%	battery	life	remaining	or	(b)	five	minutes	of	light	time	remaining	and	

otherwise	complying	with	the	flight	restrictions	above.	

14 CFR 91.203(a) & (b): Carrying Civil Aircraft Certification and Registration

The	regulation	provides	in	pertinent	part:	

(a)	Except	as	provided	in	§	91.715,	no	person	may	operate	a	civil	aircraft	unless	it	has	within	it	

the	following:	

(1)	An	appropriate	and	current	airworthiness	certificate..	.	

(b)	No	person	may	operate	a	civil	aircraft	unless	the	airworthiness	certificate	required	by	

paragraph	(a)	of	this	section	or	a	special	flight	authorization	issued	under	§91.715	is	displayed	

at	the	cabin	or	cockpit	entrance	so	that	it	is	legible	to	passengers	or	crew.	

The	sUAS	fully	loaded	weighs	no	more	than	55	lbs.	and	is	operated	without	an	onboard	pilot.	As	

such,	there	is	no	ability	or	place	to	carry	certification	and	registration	documents	or	to	display	

them	on	the	sUAS.	
An	equivalent	level	of	safety	will	be	achieved	by	keeping	these	documents	at	the	ground	control	

point	where	the	operator	flying	the	sUAS	will	have	immediate	access	to	them,	to	the	extent	they	

are	applicable	to	the	sUAS.		The	FAA	has	issued	numerous	exemptions	to	this	regulation.		A	

representative	sample	of	other	exceptions	includes	Exemption	Nos.	9565,	9665,	9789,	9789A,	

9797,	9797A,	9816A,	and	10700.	

14 CFR 91.405(a); 407(a)(1); 409(a)(2); 417(a) & (b): Maintenance Inspections

These	regulations	require	that	an	aircraft	operator	or	owner		"shall	have	that	aircraft	inspected	

as	prescribed	in	subpart	E	of	this	part	and	shall	between	required	inspections,	except	as	

provided	in	paragraph	(c)	of	this	section,	have	discrepancies	repaired	as	prescribed	in	part	43	

of	this	chapter...,"	and	others	shall	inspect	or	maintain	the	aircraft	in	compliance	with	Part	43.		

Given	that	these	sections	and	Part	43	apply	only	to	aircraft	with	an	airworthiness	certificate,	

these	sections	will	not	apply	to	the	Applicant.		Maintenance	will	be	accomplished	by	the	

operator	pursuant	to	the	flight	manual	and	operating	handbook	as	referenced	in	the	

Appendices.	An	equivalent	level	of	safety	will	be	achieved	because	the	sUAS	is	limited	in	size	

and	will	carry	a	small	payload	and	operate	only	in	controlled	areas	for	limited	periods	of	time	

from	no	higher	than	400	feet	AGL..		If	mechanical	issues	arise	the	sUAS	can	land	immediately.		

As	provided	in	the	Appendices,	the	operator	will	ensure	that	the	sUAS	is	in	working	order	prior	

to	initiating	flight,	perform	required	maintenance,	and	keep	a	log	of	any	maintenance	

performed.		Moreover,	the	operator	is	the	person	most	familiar	with	the	aircraft	and	best	suited	

to	maintain	the	aircraft	in	an	airworthy	condition	to	provide	the	equivalent	level	of	safety.	

FEDERAL REGISTER PULICATION SUMMARY

Pursuant	to	14	C.F.R.	Part	11,	the	following	summary	is	provided	for	publication	in	the	Federal	

Register,	should	it	be	determined	that	publication	is	needed:			

Vantage Aerial Media seeks an exemption from the following rules:		14 CFR Part 21

Subpart H; 14 CFR 91.203(a)(1); 14 CFR Part 27; 14 CFR 45.23(b); 14 CFR 61.113(a)&(b);

14 CFR 91.7(a); 14 CFR 91.9(b)(2); 14 CFR 91.103; 14 CFR 91.109(a); 14 CFR 91.119; 14

CFR 91.121; 14 CFR 91.151(a); 14 CFR 91.203(a) & (b); 14 CFR 91.405(a); 14 CFR

91.407(a)(1); 14 CFR 91.409(a)(2); 14 CFR 91.417(a) & (b) to commercially operate a

small unmanned aerial system		(sUAS, 55 lbs. or less) for the purpose of inspection,

monitoring, mapping and photographing equipment and engineering studies.

Approval of exemptions allowing commercial operations of sUAS will create a level of

safety by reducing risk.		Conventional inspections and construction monitoring tasks

involve extreme risks to personnel physically climbing structures and/or utilizing high rise

equipment both of which create numerous and extreme risk to such personnel.		In contrast,

a sUAS weighing fewer than 55 lbs. and powered by batteries eliminates virtually all of

that risk.		The sUAS will carry no passengers or crew and, therefore, will not expose

personnel to any of the risks described above.
Privacy

All flights will occur over private or controlled access property with the property owner's

prior consent and knowledge.		The granting of this exemption request will provide

innovative safety operations.

Satisfaction	of	the	criteria	provided	in	Section	333	of	the	Reform	Act	of	2012‐‐size,	weight,	

speed,	operating	capabilities,	proximity	to	airports	and	populated	areas	and	operation	within	

visual	line	of	sight	‐	provide	more	than	adequate	justification	for	the	grant	of	the	requested	

exemptions	allowing	commercial	operation	of	applicant's	sUAS	in	and	pursuant	to	the	

Procedures	appended	hereto.	

Sincerely,	

Ryan	Baker,	Director	of	sUAS	Flight	Operations

GENERAL

NOTE:	In	an	effort	to	minimize	costs	and	maximize	spare	parts	availability,	many	COTS	

(commercial	off	the	shelf)	components	have	been	utilized.	Some	may	have	slight	modifications	to	

better	suit	this	application.	Most	COTS	products	have	separate	data	sheets,	assembly	manuals	and	

instruction	manuals.	They	are	reference	in	this	document,	with	key	factors	being	emphasized.	

As	with	all	high	technology	products	utilizing	constantly	evolving	software,	it	is	important	to	

periodically	check	for	online	upgrades	to	the	COTS	components,	including	hardware,	firmware	

and	software.	

WARNING:	Great	care	must	be	taken	with	the	batteries.	Much	of	this	manual	and	supplemental	

information	is	devoted	to	the	use	and	care	of	the	batteries,	especially	the	flight	batteries.	They	are	

less	volatile	than	gasoline,	though	they	should	be	treated	with	the	same	respect.	Become	very	

familiar	with	proper	techniques	of	their	use.

WARNINGS

o Never	power	a	video	transmitter	or	receiver	without	an	antenna	connected	or	overload	

failure	will	occur.	

o Read	all	information	regarding	batteries	contained	in	this	manual	and	supplements.	

o Batteries	are	highly	flammable	and	can	explode,	especially	when	fully	charged.	

Improper	charging,	vibration,	impact,	high	discharge,	etc.	can	lead	to	explosion	and	fire.	

Batteries	must	be	charged	under	constant	supervision	and	using	proper	precautions.	

o Batteries	fully	charged	must	be	handled	with	extreme	care.	

o Store	batteries	between	20%	‐	50%	charged	state.	Fully	charge	just	before	use.	

o Fully	charged	batteries	which	are	not	to	be	used	within	24	hours	should	be	discharged	

to	20%	‐	50%	charged	state.	

o Discharging	LiPoly	batteries	in	excess	of	80%	of	their	rated	capacity	can	cause	harm	to	

the	batteries.	

o Using	more	than	one	battery	at	a	time	requires	the	proper	wiring	harness	so	that	the	

voltage	is	no	more	than	25.2V.	Over	voltage	will	cause	serious	damage	to	electrical	

equipment.	

o Using	more	than	one	battery	at	a	time	requires	weight	and	balance	checks.	Proper	CG	is	

critical	to	performance.	Airframe	must	not	be	overloaded.	

o Propellers	must	be	balanced	to	avoid	excessive	vibration.	

o GPS/Compass	must	be	facing	forward.	

o Do	not	use	GPS	Mode	without	GPS	lock.	

o Use	low	strength	thread	locking	compound	on	all	screws.	

o Wireless	Video	and	Data	ranges	vary	considerably	on	many	factors	including	weather,	

equipment,	and	obstructions.	Be	prepared	for	com	failures.

POWER & POWERPLANTLIMITATIONS

o 40	Amps	max	per	motor	

o 40	Amps	max	per	speed	control	

o 320	Amps	max	total	

o Do	not	exceed	80‐90%	discharge	of	rated	battery	capacity	

o Do	not	charge	batteries	which	are	warmer	than	air	temperature

WEIGHT LIMITS

o Takeoff	Weight	Max:	24	lbs	

 Must	be	checked	prior	to	takeoff	if	any	change	in	equipment	is	made	

CENTER OF GRAVITY LIMITS

o 3mm	from	the	center	of	any	of	the	three	pairs	of	arms	

 Must	be	checked	before	every	flight	to	ensure	batteries	were	installed	in	the	

proper	location.	

 Check	all	4	pairs	of	arms	before	flight	

MANEUVERLIMITS

o This	aircraft	is	intended	for	non‐aerobatic	operations	

o G‐loading	maximum:	2G	
TEMPERATURE LIMITS

o Operating	Temp	Range:	‐10°C	to	+40°C	

o In	cold	temperatures	

 Keep	IMU	at	room	temperature	if	possible	before	the	flight	

 Keep	Batteries	above	5°C	before	flight	

 Do	not	fly	with	any	frost	or	ice	on	the	propellers	

o In	warm	temperatures	

 Batteries	heat	up	when	discharged	

 The	higher	the	discharge	rate	the	higher	the	temperature	increase	during	use	

 At	temperatures	above	45°C,	use	of	2	or	more	batteries	is	required	to	lower	the	

load	on	any	one	battery	pack	to	keep	it	cooler.	

WEATHER LIMITS

o Light	dust	and	light	rain	require	the	use	of	a	shield	for	the	electronics	in	the	center	

section.	

o Light	dust	and	light	rain	are	acceptable	for	the	unshielded	motor	and	ESC.	

RANGE LIMITS

o FUEL	

 Fuel	capacity	is	a	primary	limiting	factor.	

 Flying	into	the	wind	will	use	more	battery	power	to	travel	the	same	ground	

distance.	Higher	air	speeds	will	be	required	to	penetrate	the	wind	which	used	

more	battery	power.	Take	this	into	account	when	flying	a	mission.	

 Where	possible,	fly	upwind	at	the	start	of	a	mission	and	downwind	at	the	end	to	

avoid	depleting	the	battery	before	returning	to	base.	Have	alternative	landing	

sites	available	in	case	of	emergency	landing.	

o WIRELESS	LINK	

 Wireless	links	will	be	stable	in	LOS	(line	of	sight)	in	most	conditions	

 Wireless	links	are	always	susceptible	to	shorter	ranges	due	to	

 Atmospheric	conditions	

 Other	transmission	devices	in	the	area	

 Jamming	

 Antennas	not	aligned	properly	
 Improper	voltage	

 Antenna	blockage	from	Aerial	Vehicle	(AV)	in	certain	positions	

 Multipath	–	reflection	off	buildings	or	ground	which	cause	multiple	

signals	to	arrive	at	different	times	and/or	phase.	
SECTION 3

EMERGENCY PROCEDURES

MOTOR FAILURE

o Operation	is	possible	with	one	motor/ESC/propeller	failure	

 The	two	adjacent	motors/ESCs	will	be	increased	in	thrust	automatically	by	the	

flight	controller	to	overcome	the	loss	

 In	cases	where	the	airframe	is	highly	loaded	the	maximum	rating	of	40	amps	

may	be	exceeded	by	these	two	motors/ESCs	

 Operation	should	be	terminated	as	soon	as	possible	to	reduce	the	possibility	of	

damage	to	the	remaining	motors	

COMMUNICATION FAILURE

o Video	link	failure	

 5.8	Ghz	being	the	shortest	wavelength	in	general	AV	use	has	the	least	ability	to	

penetrate.	This	link	should	be	the	first	to	be	lost.	

 It	is	best	to	lose	video	first!	It	is	the	least	likely	to	cause	a	crash	when	it	fails.	

5.8	Ghz	can	lose	link	with	little	warning.	

 Ensure	that	the	GCS	station	antennas	are	perpendicular	to	the	AV.	Do	not	point	

the	antenna	at	the	AV.	

 Yaw	the	AV	to	change	the	antenna	position	

 Other	links	should	still	be	good.	Return	back	to	the	GCS	until	link	is	restored.	

Transmitters	produce	heat	when	in	operation.	When	overheated	they	may	have	

thermal	protection	which	interrupts	use	temporarily.	Use	of	a	heat	sink	or	fan	

may	be	required	especially	with	high	ambient	temperatures.	

 Higher	gain	antennas	may	be	used,	but	do	so	with	caution.	High	gain	antennas	

are	directional.	

 Multiple	antennas	using	“diversity”	can	be	used.	Diversity	is	a	device	which	

determines	the	best	signal,	and	uses	that.	

 5.8	Ghz	even	at	high	wattages	theoretically	has	less	range	than	lower	

frequencies.	Changing	to	1.3	Ghz	is	an	option,	though	there	are	other	issues	to	be	

considered.	

o RC	link	failure	

 2.4	Ghz	antennas	can	lose	link	with	little	warning.	

 Anything	in	between	the	two	antennas	can	cause	temporary	signal	loss	

especially	a	person.	
 Hold	the	transmitter	up	in	the	air	and	walk	in	the	general	direction	of	the	AV.	

 Ensure	that	the	antenna	is	vertical.	Do	not	point	the	antenna	at	the	AV.	

 The	failsafes	on	the	RC	link	should	be	set	so	that	the	AV	returns	to	home.	Should	

this	require	a	heading	change,	the	antenna	may	move	into	a	more	desirable	

position	and	link	will	be	restored.	

 The	onboard	equipment	may	block	the	signal.	Yaw	the	AV	so	that	the	antennas	

point	towards	the	GCS.	

 A	LRS	(long	range	system)	can	be	used	as	a	permanent	solution.	This	is	higher	in	

wattage	and	usually	on	433	Mhz.	

Data Link Failure

 900	Mhz	do	not	lose	link	without	some	warning.	When	drop	outs	are	noticed	to	

increase	in	frequency	that	is	the	limit	of	the	range.	

 If	using	900	Mhz,	this	is	on	cell	phone	frequency.	If	a	cell	tower	is	nearby	it	can	

swamp	the	signal.	900	Mhz	may	not	be	usable	in	that	area.	Change	to	a	different	

freq.	or	remain	closer	to	the	AV	

LOW BATTERY POWER

 Fail‐safes	can	be	set	such	that	in	the	event	of	low	battery	power,	either	due	to	a	

failure	or	too	long	of	a	flight,	the	warning	light	on	the	AV	will	constantly	flash	

amber.	This	is	the	first	level	of	warning.	

 The	second	warning	level	is	red	flashing	lights	

 Auto	landing	will	occur	when	battery	power	is	low.	It	may	land	in	a	tree	or	a	

lake,	so	this	is	not	desirable.	

 Landing	with	80‐90%	of	battery	depleted	is	best.	Therefore	landing	with	17,000	

mah	used	and	3,000	mah	remaining	of	a	20,000	mah	battery	is	desirable.	

Batteries	should	be	drawn	down	equally	when	in	use	if	they	are	both	charged	

equally	and	both	in	relatively	the	same	condition/age.	

 Do	not	mix	partially	charged	batteries.	Only	use	completely	charged	batteries.	

 Over	discharging	a	battery	below	19.8V	can	permanently	damage	the	battery.	
GCS FAILURE

 Takeover	by	the	external	pilot	should	happen	ASAP	using	the	RC	link.	

 Most	often	happens	due	to	a	low	battery.	

 Keep	a	spare	3	cell	LiPoly	battery	with	the	appropriate	plug	to	plug	into	the	

charge	jack	for	emergency	use.	Most	chargers	are	19V	output	which	is	roughly	

equivalent	to	a	4‐cell	battery.	3‐cell	batteries	may	work.	

COMPASS CALIBRATIONERROR

 If	the	compass	is	out	of	calibration	the	warning	light	will	flash	red.	This	is	the	

same	signal	as	low	voltage.	If	the	voltage	is	correct,	there	is	a	calibration	error.	

 Recalibrate	the	compass	following	the	instruction	manual

FIRE

 Fires	can	occur	due	to	a	short	circuit	or	battery	failure.	

 Disconnect	the	battery	ASAP	unless	there	is	danger	in	doing	so	if	there	is	any	

electrical	issue.	

 It	is	not	possible	to	put	out	a	battery	fire.	

 Do	not	attempt	to	put	out	a	battery	fire.	Use	a	fire	extinguisher	to	put	out	fires	

surrounding	the	battery.	A	CO2	fire	extinguisher	is	better	than	the	powder	or	

chemical	type.	CO2	does	not	leave	a	residue.	Water	can	be	used	though	it	may	

cause	other	electrical	component	failures.	

FORCED LANDINGS

 If	alternate	emergency	landing	zones	should	be	chosen	ahead	of	time.	

 Be	sure	that	the	LZ	is	clear	of	people	to	avoid	any	incidents.	

 Land	in	the	nearest	LZ	which	is	clear	of	people.	

 Announce	your	intentions	of	landing	as	loud	as	necessary	to	alert	people	of	the	

incoming	AV.	
SECTION 4

SET UP SUGGESTIONS

ELECTRONICS BURN IN

o We	recommend	that	you	put	weights	onto	the	landing	skids	to	keep	the	copter	on	the	

ground	and	run	the	copter	at	about	70%	throttle	for	about	2	hours	to	burn	in	the	

electronics.	Most	electronic	failures	occur	in	the	first	2	hours	of	operation.	

GPS/COMPASS MAST LENGTH

o We	found	that	the	higher	the	mast,	the	better	the	GPS	reception

Nex5N vs. Nex7 vs. Canon 5D vs. Panasonic GH3

o These	cameras	are	excellent	for	stills,	and	very	good	for	video.	The	best	for	video	is	the	

Panasonic	GH4	with	4k	capabilities.	

o We	found	that	the	Nex	5N	takes	exceptional	quality	stills	and	video,	though	most	

professionals	use	the	Nex	7.	The	Canon	5D	is	better	than	the	Nex7	due	to	its	larger	

sensor.	

o Use	the	Panasonic	GH4	if	you	primarily	shoot	video	

RADIO SET UP

o Follow	the	instructions	in	the	manual	

o We	prefer	the	switch	assignment	as	shown	in	the	checklists	above	though	feel	free	to	

modify	to	your	liking	

COPTER COMMAND AND CONTROL

o We	recommend	the	use	of	a	dual	rate	switch	for	main	copter	operation.	

 High	rate	–	used	to	initialize	the	motors.	The	flight	controller	will	not	engage	

unless	it	sees	full	down	throttle,	full	left	rudder,	full	left	cyclic	and	full	back	

cyclic.	However,	these	may	be	too	high	for	normal	flying.	On	high	rate	it	is	helpful	

to	utilize	fairly	high	exponential	to	make	the	stick	feel	soft	around	center.	Adjust	

to	your	preference.	

 Low	rate	–	used	for	typical	flying.	Set	the	end	point	adjustments	such	that	full	

stick	deflection	offers	the	maximum	speed	required	in	normal	flying.	If	

conditions	require	higher	flight	speeds,	switch	to	high	rate.	On	low	rate	it	is	also	

helpful	to	utilize	a	small	amount	of	exponential	to	make	the	stick	feel	soft	around	

center.	Adjust	to	your	preference.	
ZENMUSE COMMAND AND CONTROL

o We	recommend	the	use	of	a	dual	rate	switch	for	gimbal	operation.	

 High	rate	–	used	to	initialize	the	gimbal.	The	gimbal	may	not	engage	unless	it	

sees	full	motion.	However,	these	may	be	too	high	for	shooting	video	smoothly.	

This	is	best	for	still	photography	so	as	to	put	the	camera	on	target	quickly.	On	

high	rate	it	is	helpful	to	utilize	fairly	high	exponential	to	make	the	stick	feel	soft	

around	center.	Adjust	to	your	preference.	

 Low	rate	–	used	for	videography.	Set	the	end	point	adjustments	such	that	full	

stick	deflection	offers	the	maximum	speed	required	for	videography.	If	

conditions	require	higher	gimbal	speeds,	switch	to	high	rate.	On	low	rate	it	is	

also	helpful	to	utilize	a	small	amount	of	exponential	to	make	the	stick	feel	soft	

around	center.	Adjust	to	your	preference.	

TIMERS

o Use	of	the	countdown	timer	is	a	good	backup	method	to	ensure	landing	with	battery	

power.	

 Set	the	timer	for	20	minutes	(or	what	you	deem	appropriate)	and	have	it	start	

when	the	throttle	is	over	1/4.	Then	adjust	the	timer	upwards	until	the	amount	of	

battery	used	is	about	80‐90%	of	the	total	available.	If	using	20,000	mah	

batteries,	a	total	of	17,000	mah	would	be	the	target.	Set	the	timer	such	that	you	

have	a	minute	or	so	to	land	after	the	alarm	sounds	so	that	you	have	adequate	

time	to	return	to	base.	Adjust	to	your	preference.	

BATTERIES

o Replace	the	transmitter	standard	battery	with	a	Lipoly	battery	to	extend	use	times	to	8	

hours.	Supplied	batteries	often	last	about	2	hours.	
NORMAL PROCEDURES

PREFLIGHT CHECKLIST

o Confirm	all	communication	radios	are	operational	

 Radios	with	others	in	the	group	

o Set	a	perimeter	of	500	feet	

 Area	must	be	clear	of	people	to	avoid	collision	

o Check	for	overhead	power	lines	and	other	obstacles	to	avoid	

o Check	structural	integrity	

 In	event	of	prior	crash,	inspect	all	booms,	props	and	motor	mounts	for	excessive	

flex	indicating	structural	fatigue/failure	

o Have	a	manual	flight	plan	avoiding	obstacles.	

o Load	auto	flight	plan	if	using	one	

 Be	sure	that	the	total	flight	time	is	under	15	minutes	to	avoid	low	battery	

o Clean	lens	

 Remove	lens	cap	

o Ensure	camera	has	SD	card	installed	

o Install	batteries	

 Ensure	that	the	straps	are	tight	and	the	Velcro	keeps	the	batteries	from	moving	

which	will	avoid	a	shift	in	the	CG	(Center	of	Gravity	–	or	that	it	balances	evenly)	

o Check	CG	(Center	of	Gravity)	

 Lift	the	copter	on	each	of	the	3	pairs	of	arms.	The	copter	should	balance	

properly.	If	not,	do	not	fly.	Rearrange	the	equipment	to	achieve	proper	

CG	

o IMU	pointing	forward	

 The	Inertial	Measurement	Unit	is	set	so	that	it	must	face	forward	

o GPS/Compass	installed,	limited	free	play,	pointing	forward	

 This	device	must	be	installed	with	a	screw	to	hold	it	in	place.	It	cannot	vibrate	

easily.	If	it	does	not	point	forward,	the	corrections	in	ATTI	and	GPS	mode	will	be	

incorrect	and	it	will	crash.	The	FC	will	provide	a	warning	with	constant	flashing	

white	lights.	

o Level	copter	using	a	bubble	level	with	front	pointing	in	correct	direction	for	course	lock	

–	do	not	turn	on	

 Keep	in	mind	the	best	angle	for	pointing	the	landing	gear	in	the	direction	that	

will	keep	the	landing	gear	out	of	the	shot	when	flying.	
o Turn	on	Pilot	Tx	

o If	using	the	rate	gyro,	set	it	at	the	correct	position.	This	is	usually	a	slider	switch.	Gains	

should	have	the	range	set	from	200	–	350.	Use	the	highest	gain	possible	which	does	not	

cause	oscillation.	

o Check	Model	Selection	on	Tx	to	be	S1000	

o Throttle	on	Tx	Down	

o Return	to	Home	switch	Off	

o Adjust	gain	to	correct	position	(if	required)	

o Manual	Flight	Mode	Switch	to	manual	(not	ATTI	or	GPS	mode)	

o Flight	Path	Switch	Off	–	Not	Course	or	Home	or	POI	

o Check	Tx	battery	voltage	(above	7.5v)	

 These	settings	above	are	required	to	initialize	the	copter	properly.	If	the	

switches	are	in	the	incorrect	position,	it	will	not	initialize	properly	which	may	

cause	some	of	the	functions	like	course	lock	or	GPS	mode	to	not	operate	

properly.	

 If	the	copter	does	not	function	properly	after	takeoff,	land	immediately	and	

disconnect	the	copter	power.	Then	put	all	the	switches	in	the	proper	position	for	

initialization	and	turn	the	power	back	on	to	the	copter.	

o Count	down	timer	should	be	set	to	20	minutes.	This	can	be	adjusted	to	your	flying	style.	

The	timer	should	engage	at	1/4	throttle	and	trigger	an	alarm	at	the	proper	time.	This	is	

a	backup	alarm	in	case	the	indicator	lights	on	the	copter	are	not	visible.	

o Turn	on	Video	Tx	

o Check	Model	Selection	on	Tx	–	should	read	Zenmuse	

o Check	Tx	battery	voltage	(above	7.5v)	

o HDMI	switch	Off	

o Freestyle	switch	Off	(FPV	On)	

 These	settings	above	are	required	to	initialize	the	Zenmuse	properly.	If	the	

switches	are	in	the	incorrect	position,	it	will	not	initialize	properly	which	may	

cause	some	of	the	functions	like	live	video	or	gimbal	operation	to	not	operate	

properly.	

 If	the	camera	or	gimbal	do	not	function	properly,	disconnect	the	copter	power.	

Then	put	all	the	switches	in	the	proper	position	for	initialization	and	turn	the	

power	back	on	to	the	copter.	

o Engage	power	to	copter	

 Plug	in	the	battery	pack.	

.	
 6	quick	chirps	should	be	heard	confirming	6S	LiPoly	batteries	are	recognized	by	

the	ESCs.	

 Hearing	less	than	6	chirps	indicates	fewer	cell	battery	packs	are	being	

recognized	which	is	incorrect.	Check	for	improper	or	damaged	batteries.	

o Do	no



t	move	or	vibrate	the	copter	until	30	seconds	after	full	GPS	Lock	

Initial	3	red	blinks	is	normal	meaning	no	GPS	lock.	No	red	flashes	indicates	full	

    GPS	lock.	

 Continue	with	checklist	as	you	are	waiting	for	full	GPS	lock,	but	do	not	move	the	

copter.	

 If	the	GPS	takes	more	than	5	minutes	to	lock,	there	is	a	problem	with	the	area.	It	

is	not	receiving	the	proper	signals	from	the	satellites.	GPS	signals	are	weak,	so	

trees,	people,	buildings,	terrain,	weather,	have	an	effect.	Move	the	copter	into	a	

more	open	area	where	it	can	more	easily	see	the	satellites.	

o Check	Copter	Voltage	from	both	Tx’s	(transmitters)	

 The	transmitters	receive	a	signal	from	the	corresponding	receivers.	The	voltages	

are	regulated	to	about	5v.	If	the	voltage	is	below	4.4v	or	above	6v	do	not	fly.	

There	may	be	power	regulation	issues.	The	receivers	cannot	work	outside	this	

voltage	consistently.	Also	there	is	some	issue	if	the	voltage	is	outside	that	range	

which	should	be	resolved	before	flying.	

o Engage	Attitude	Mode	–	Must	achieve	double	amber	flash	

o Engage	GPS	Mode	–	Must	achieve	double	purple	flash	

o Engage	course	cock	mode	–	Must	achieve	double	green	flash	

o Disengage	course	lock	mode.	Must	achieve	double	purple	flash.	Stay	in	this	mode	until	

just	prior	to	takeoff,	after	takeoff	at	any	time,	or	do	not	use.	

o Do	not	engage	motors.	Set	throttle	to	center	position.	Must	achieve	single	purple	flash	

when	in	GPS	mode.	

 To	verify	that	the	sticks	are	all	centered	properly:	

 With	throttle	in	the	center	position,	use	the	trim	buttons	on	the	transmitter	to	

check	that	the	sticks	are	centered.	Trim	the	roll	(the	stick	located	on	the	right	

side	of	the	transmitter	when	moved	to	the	right	and	left)	to	the	right,	counting	

the	number	of	clicks	until	a	double	flash	occurs.	Then	center	the	trim.	Then	move	

the	trim	to	the	left,	counting	the	number	of	clicks	until	a	double	flash	occurs.	An	

equal	number	of	clicks	should	be	counted	each	side	of	center.	

 Do	this	check	for	the	3	stick	movements	other	than	throttle.	

 Center	the	trim	such	that	when	the	stick	is	in	the	neutral	position	that	there	are	

equal	numbers	of	clicks	in	each	direction.	This	ensures	that	when	the	sticks	are	

neutralized	that	the	flight	controller	will	recognize	this	signal	and	engage	GPS	

mode.	
o Calibrate	GPS/Compass	before	the	first	flight	each	day	or	if	receiving	continuous	red	

blinks	or	continuous	white	blinks.	

 Flip	the	GPS	mode	switch	7	times	very	quickly	from	manual	to	GPS.	End	with	the	

switch	in	the	manual	position.	The	indicator	light	will	be	blue.	Rotate	the	copter	

about	1.5	turns	in	a	horizontal	position.	A	green	flashing	light	indicates	that	this	

is	complete.	Then	hold	the	copter	vertically	and	rotate	about	1.5	turns.	A	white	

flashing	light	indicates	that	this	is	complete.	Repeat	if	necessary	until	this	is	

completed.	

o After	calibration,	reset	the	copter	by	cycling	battery	with	copter	pointed	in	the	correct	

heading	for	course	lock.	

o Engage	Camera	

o HDMI	switch	On	

 This	will	stop	video	from	playing	on	the	back	of	the	camera	and	will	send	the	

video	signal	to	the	video	transmitter	via	the	HDMI	connection.	

o Freestyle	switch	On	(FPV	Off)	

 This	allows	the	camera	to	be	operated	freely	through	the	transmitter	

o Verify	camera	operation	

 Operate	the	shutter	

 Set	the	focus	to	auto	or	manual.	Manual	setting	is	usually	set	to	infinity	to	stop	

constant	focusing	of	the	camera.	

o Verify	data	link	if	installed	

 Roll	the	copter	about	45	degrees	on	its	side	by	lifting	one	side	of	the	copter	and	

resting	one	side	of	the	landing	gear	on	the	ground	

 A	corresponding	roll	should	be	seen	on	the	gauge.	

 If	the	copter	is	rolled	to	the	right,	it	will	appear	on	the	gauge	that	the	horizon	

rolls	to	the	left	–	not	the	right	because	the	view	from	inside	the	copter	is	that	the	

horizon	rolls	the	opposite	direction	of	the	copter.	

o Verify	altitude	is	about	0	via	gauge	on	computer	

 If	it	is	not	about	0,	the	altitude	settings	for	the	waypoints	will	be	off	by	this	

amount.	This	could	cause	the	copter	to	fly	at	10	meters	or	30	meters	if	the	

waypoint	is	set	for	20	meters	and	the	altitude	is	off	by	10	meters	one	way	or	

another.	If	the	copter	thinks	it	is	at	10	meters	when	it	is	on	the	ground,	then	it	

will	only	rise	10	meters	above	the	ground	to	achieve	what	it	believes	it	to	be	20	

meters	above	the	ground.	

 The	altitude	can	be	reset	using	the	ground	control	software	by	going	to	altitude	

offset.		

o Alternate	Emergency	Landing	Sites	Established
NORMAL TAKEOFF

o Engage	GPS	mode	–	Double	purple	flash	when	the	throttle	is	down.	

o Switch	to	Course	Lock	flight	mode	if	required.	Purple	flashes	are	replaced	with	green	

flashes.	Flying	in	course	lock	is	not	required,	but	helpful	in	many	instances.	

o Announce	loudly:	“CLEAR	PROP”	

o Move	both	of	the	sticks	to	the	bottom	left	corners	to	engage	the	motors.	Within	1	

second	move	the	throttle	up	1/8	–	1/4.	The	copter	should	not	lift	off	until	about	50%	

stick	is	reached.	

o Verify	data	and	video	links	before	lifting	off.	If	anything	is	not	working	properly,	move	

the	throttle	stick	to	low	to	disengage	the	motors	and	determine	a	solution.	

o If	all	flight	checks	are	passed,	announce	loudly:	“TAKING	OFF”	

o Advance	throttle	to	about	3/4.	Copter	must	jump	off	of	the	ground	to	avoid	one	skid	

coming	up	before	the	other	skid,	and	the	skid	on	the	ground	getting	caught	and	flipping	

the	copter	over	sideways.	

o Ascend	to	3	meters.	Then	decrease	throttle	to	50%	to	engage	the	GPS	hold.	

o Verify	links,	GPS,	Attitude,	etc.	Should	be	single	purple	flash.	

o Verify	that	the	copter	is	holding	position	within	.5m	in	all	directions.	

o Verify	camera	operation	

o Verify	course	lock	is	operational	by	rotating	90	degrees	and	pushing	forward	on	stick.	

o Verify	copter	stability.	If	unstable,	land	and	reset	gains,	recalibrate,	or	retest	as	

necessary.	

o Proceed	with	manual	mission	or	

o For	autopilot	operation	

 Ascend	to	30	feet	

 Command	aerial	vehicle	observer	(AVO)	to	proceed	with	mission.	

 Pilot	should	say	“It’s	yours”	

 Response	from	AVO	“I	have	it”	

o Manual	pilot/observer	must	monitor	the	informational	LED	and	be	ready	to	take	over	

in	manual	mode	when	necessary.	

 White	flashes	indicates	flight	controller	issue	

 Amber	flashes	indicates	low	battery	

 Red	flashes	indicate	loss	of	GPS	or	severe	battery	condition	

 Quick	decisions	are	required	when	red	flashes	are	indicated	

 10	seconds	or	more	of	loss	of	GPS	signal	will	stop	waypoint	guidance	and	

any	GPS	hold	and	put	into	manual	mode.	
 Red	indicator	light	battery	warning	requires	immediate	landing	

o Manual	pilot	to	request	copter	flight	battery	voltage	readout	from	AVO	periodically.	

 Reset	the	first	and	second	indicator	lights	as	required	for	your	set	up.	

 Also	use	the	countdown	timer	on	the	transmitter.	This	gives	a	good	indication	of	

battery	level	because	the	current	used	is	fairly	constant	from	flight	to	flight.	

POST LANDING

o Note	flight	time	from	transmitter.	Write	this	down	in	the	log	book.	

o Note	battery	power	used	during	the	flight.	Write	this	down	in	the	log	book.	

o ALWAYS	disconnect	the	main	power	to	the	AV	first,	then	turn	off	the	transmitter.	

o Check	motor	temperatures	by	touching	them	with	your	fingers.	Any	motors	which	are	

excessively	hot	should	be	further	inspected	and	possibly	replaced.	

o Check	battery	temperatures	by	touching	them	with	your	fingers.	Battery	temperatures	

should	not	be	hot	to	the	touch.	Battery	temperatures	should	be	slightly	above	ambient.	

o Inspect	all	components	especially	the	propellers	for	wear.	

o Note	in	logbook	which	batteries	were	used	to	calculate	life	cycle.

SECTION 5

PERFORMANCE

FLIGHT TIMES

o The	AV	is	designed	to	hover	at	high	efficiency.	Hovering	is	much	less	efficient	than	

flying	on	a	wing,	thus	flight	times	are	low	compared	to	fixed	wing	aircraft.	

o All	the	weight	of	the	AV	is	supported	by	power	from	the	batteries.	As	the	batteries	are	

used	in	a	flight,	the	amount	of	power	available	decreases.	Therefore	the	power	reserve	

is	constantly	decreasing	as	the	battery	is	being	used.	Thus	loading	a	rotorcraft	above	its	

limit	is	not	recommended.	While	the	AV	may	have	enough	power	to	lift	off	initially	on	a	

full	charge,	the	power	reserve	at	partial	charge	may	be	too	low	to	allow	for	

maneuvering	and	will	result	in	a	crash.	

o High	lateral	speeds	will	add	lift	to	slightly	improve	efficiency.	The	rotors	act	similar	to	

fixed	wings	at	higher	speeds.	This	increase	in	efficiency	may	be	negated	by	the	

increased	power	consumption	of	forward	flight.	

o High	winds	or	gusts	decrease	efficiency/flight	time.	The	motors	work	harder	to	hold	

position.	

o As	weight	increases	flight	times	decrease.	

WIRELESS TRANSMISSION

o Refer	to	the	specific	manuals	for	performance	ratings.	

o Wireless	communications	utilized	provide	acceptable	communication	for	line	of	sight	

(LOS).	

o In	general:	

 LOS	is	required	

 The	higher	the	GCS	antennas,	the	better	the	range	

 RSSI	(Received	Signal	Strength	Indication)	should	be	monitored	for	indication	of	

communication	drop	out.	
SECTION 6

WEIGHT AND BALANCE EQUIPMENT LIST

Center of Gravity (CG)

o CG	is	critical	to	the	efficient	operation	of	any	AV	

o When	components	are	shifted,	the	CG	will	be	altered.	

o The	main	components	which	are	moved	on	a	regular	basis	are	the	sensors	and	the	

batteries.	

o The	sensors	are	typically	in	the	front	of	the	AV,	and	the	batteries	are	located	in	the	

correct	position	to	offset	all	the	components	on	the	AV.	

o The	CG	must	be	tested	after	any	change	to	the	components	or	their	placement.	

o The	CG	should	be	tested	by	lifting	the	UV	with	fingers	on	the	bottom	of	the	arms.	Check	

all	4	pairs	of	arms.	The	CG	should	be	no	more	than	2mm	off	in	any	on	the	3	checks.	The	

closer	the	CG	is	to	the	centerlines	of	the	arms	the	more	efficient	and	the	more	stable	the	

AV	will	be.	

WEIGHT

o Weight	is	critical	to	the	operation	of	any	aircraft	

o Weight	is	especially	critical	to	a	rotor	wing	aircraft.	At	full	throttle	the	motors	have	a	

finite	amount	of	thrust.	All	the	weight	is	lifted	by	the	battery	power,	there	is	no	wing	to	

assist	in	providing	lift.	

o As	the	batteries	are	operated,	they	lose	power.	At	full	charge	they	have	about	25v.	At	

20%	remaining	capacity	they	have	about	21v.	This	is	a	loss	of	8%	of	the	power	available	

which	is	significant.	

o Do	not	overload	the	aircraft	or	there	will	not	be	sufficient	reserve	power	to	maneuver	

at	low	battery	levels.	
SECTION 7

WIRELESS COMMUNICATIONS

o Refer	to	the	specific	manuals	for	performance	ratings.	

o Never	power	a	video	transmitter	or	receiver	without	an	antenna	connected	or	overload	

failure	will	occur.	

o Wireless	communications	utilized	provide	acceptable	communication	for	LOS.	

o In	general:	

o LOS	is	required.	

o Lower	frequencies	penetrate	objects	such	as	trees	better	than	higher	frequencies.	

o Lower	frequencies	have	longer	range	than	high	frequencies	

o Higher	frequencies	can	transfer	more	data	than	lower	frequencies	

o Higher	frequencies	use	smaller/shorter	antennas	

o The	higher	the	GCS	antennas,	the	better	the	range	and	reception

o Frequencies	may	have	severe	degradation	due	to	location	to	other	admitters	such	as	

cell	towers	

o Range	must	be	constantly	monitored.	

o Alternate	antenna	types	may	be	utilized	to	improve	link/range.	Patch,	helical,	omni,	etc.	

can	be	substituted.	They	must	be	verified	before	use.	

o Alternate	frequencies	may	be	utilized	to	improve	link/range.	
SECTION 8

HANDLING, SERVICE AND MAINTENANCE

PROPELLERCARE

o Propellers	must	be	checked	each	flight	for	nicks	or	cracks	

o Propellers	are	designed	to	last	indefinitely	if	they	do	not	impact	dust,	dirt	or	more.	

BATTERY CARE AND USE

o Refer	to	instruction	sheet	included	from	the	battery	manufacturer.	Typical	information	

follows.	

o Batteries	are	highly	flammable	and	can	explode,	especially	when	fully	charged.	

Improper	charging,	vibration,	impact,	high	discharge,	etc.	can	lead	to	explosion	and	fire.	

Batteries	must	be	charged	under	constant	supervision	and	using	proper	precautions.	

o Batteries	fully	charged	must	be	handled	with	extreme	care.	

o Any	battery	which	puffs	up	is	considered	damaged	and	must	not	be	used.	It	is	in	a	

dangerous	state.	Never	charge	a	puffed	up	battery.	

o Any	battery	which	holds	less	than	80%	of	its	rated	capacity	should	be	discarded.	

o Cycle	test	each	battery	after	every	50	cycles	or	if	a	battery	is	suspected	to	have	lost	as	

significant	amount	of	its	capacity	to	determine	the	current	capacity.	

o Properly	dispose	of	batteries.	First	discharge	the	battery	fully	using	a	battery	cycler.	

Bring	to	a	recycler	such	as	a	home	improvement	store.	

o Always	charge	flight	batteries	under	“balance”	mode.	

o Flight	Battery	Recommended	Charge	Rate:	1	C		

o Flight	Battery	Maximum	Charge	Rate:	May	exceed	5C.	Charge	rates	higher	than	1C	will	

decrease	life	cycles.	Maximum	charge	rating	per	the	manufacturer	will	provide	300+	

cycles.	Use	the	lowest	charge	rate	which	is	practical.	

o Battery	Rest	Time	between	discharging	and	charging:	30	minutes	minimum,	1	hour	

maximum.	

o Do	not	charge	if	the	battery	is	more	than	2°C	warmer	than	ambient,	especially	if	the	

temperature	is	above	20°C.	The	outer	surface	is	cooler	than	the	inner	core	after	use.	

Damage	will	occur	when	charging	a	warm	battery.	

o Recommended	Battery	Discharge	Amount:	80%.	Using	more	of	the	capacity	of	the	

battery	will	decrease	the	life	cycles	

o As	battery	temperature	approaches	freezing	the	capacity	of	Lithium	Polymer	batteries	

decrease.	Keep	warmer	than	5°C	before	installing	into	the	UV	(unmanned	vehicle).	
o Battery	capacity	decreases	at	higher	discharge	rates.	Using	more	batteries	decreases	

the	discharge	rate	of	each	battery	thereby	extending	individual	battery	capacity	slightly.	

o Lower	discharge	rates	improve	the	life	cycles.	

o Batteries	are	rated	at	greater	than	300	life	cycles.	1,000+	life	cycles	are	possible.	

o Batteries	must	not	be	stored	above	60%	charged	state	for	extended	periods.	

o Batteries	should	be	stored	below	25°C	for	extended	periods	

o Store	batteries	between	40%	‐	60%	charged	state.	Fully	charge	just	before	use.	

o Fully	charged	batteries	which	are	not	to	be	used	within	24	hours	should	be	discharged	

to	40%	‐	60%	charged	state	using	the	battery	discharger.	

PREVENTATIVE MAINTENANCE

o ANNUAL	INSPECTION	

 If	the	airframe	has	in	excess	of	300	hours	in	a	one	year	period,	an	annual	

inspection	must	be	completed.	

 Disassemble	the	AV	and	inspect	all	components	for	wear	and	replace	any	

components	as	required.

1.3 Compass Calibration 

The Compass can assistant the GPS to position the aircraft, which is very important during flight. As we know, 

the compass is very sensitive to electromagnetic interference, which will cause abnormal compass data, and lead 

to poor flight performance or even flight failure. Compass Calibration MUST be done for first time use.

It is recommended to calibrate the compass outdoors after the Controller Unit finds 7 or more GPS satellites. 

Regular calibration enables the compass to keep optimal performance.

Calibration Cautions 

(1) DO NOT calibrate your compass where there is strong magnetic interference, such as magnetite, 

car park, and steel reinforcement under the ground.

(2) DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.

(3) Compass Calibration is very important; otherwise the flight control system cannot work.

3 HL POI BTM

 

Step 2 Forward Direction, HP and POI Recording 

After you enable the IOC in assistant software, the flight control system will record the forward direction and home 

point automatically after power on, if the recording conditions are met. You can manually re-record the forward 

direction, home point and POI during flying. Note that no BTM recording is required. Read the following table for 

the recording method details.

(2) The new Home Point and Forward Direction can be set only after one has already been recorded 

automatically.

(3) HP is not only used in IOC, but also in FailSafe and Low voltage as go home and landing

destination. The flight control system will automatically record the HP even if IOC function is 

disabled in Assistant software but Forward direction and POI can be recorded only after IOC is 

enabled.

(4) Once the Home Point is recorded successfully, LED will blink (6) continually under the 

following conditions. All conditions must be true.

1. ≥6.

2. Distance between aircraft and the recorded home point is less than 8m.

3. Current control mode is in GPS ATTI. Mode or ATTI. Mode of switch position-2.

 

Step 3 CL, HL and POI flying test

DO NOT toggle the IOC switch frequently in HL flying to avoid re-recording the HP unwittingly.

IOC function is available only when all the required conditions are satisfied. If any condition is omitted

the flight control system will exit IOC. Please keep an eye on the LED to know the current control mode.

(1) It is recommended to start the HL flight when the aircraft is >10m away from the HP. If starting

the HL when the distance between aircraft and HP is less than 10m and it’s the first time you 

start HL after power on, then the flight control system will only enter HL after flying out of the 
©2013-2014 DJI. All Rights Reserved. 36

10m range.

(2) During HL flying if one of the following conditions occur, the flight control system will exit HL and 

enter into CL: the aircraft is within of 10m from HP; the control mode is changed to ATTI. Mode; 

<6(LED (2) or (3)).

Step 4 Banked Turn mode flying test 

Banked Turn Mode is useful when you want to perform banked turns one handed. It allows you to pitch and roll to 

turn without using the yaw stick. 

Application examples:

1. Normal and FPV aerial photography in this mode is smooth and simple, giving a different visual feel to your 

work.

2. In this mode, the roll and yaw sticks are combined to help you perform banked turns with only one hand.

Setting steps (Mode 2):

1. To enable Banked Turn Mode, replace the POI gear of the IOC switch with Banked Turn gear. 

2. With Banked Turn Mode activated, you can circle the aircraft with just one stick. To do this, Mode 2 (throttle 

on the left stick) users should select the “Use Roll” option while Mode 1 (throttle on the right stick) users 

should select the “Use Yaw” option. 
©2013-2014 DJI. All Rights Reserved. 37

Using Banked Turn Mode (Mode 2):

1. Select “Use Roll” to disable the yaw stick or select “Use Yaw” to disable the roll stick.

2. Push pitch stick to move the aircraft forward or backward.

3. After that, Push roll stick left or right to perform banked turn as the following diagram shown. No yaw stick 

required. 

4. When the aircraft is hovering, yaw is controlled by the roll stick instead.

5. Rapidly pull the pitch stick to the mid-point to stop the aircraft.

(1) Banked Turn Mode works only with GPS-ATTI mode (GPS ≥6). The aircraft will stop and hover when 

less than 6 satellites are found. 

(2) Once the aircraft performs side slip, adjust the drift damping value. Note that too big value may lead 

to aircraft vibration.

4.1.2 Cruise Control 

Cruise Control allows you to lock the speed of the aircraft, freeing you to control the gimbal while maintaining 

flight. 

Application examples:

1. By maintaining steady flight, you can focus more on your shots and gimbal control, and your total flight time is 

increased by eliminating unnecessary speed changes.

2. Activate Cruise Control to lock your aircraft into its current horizontal speed when you release the control 

sticks.

Cruise Control only works when IOC has been enabled. Tick the Cruise Control box in the A2 Assistant to enable it. 
©2013-2014 DJI. All Rights Reserved. 38

Assign a 3-gear switch on the remote control for Cruise Control. Follow the steps below to use Cruise Control. 

Use the control sticks to accelerate the aircraft to your target speed then toggle the assigned Cruise Control switch 

to “Set” or “Continues”.

The action of three different gears of the cruise speed is defined as follow:

 Close 

Deactivate Cruise Control. 

 Set 

Move the switch to this position in flight to “Set” the cruising speed. The speed at the point that the switch is 

toggled will be maintained. If you use the control sticks to adjust aircraft speed, the aircraft will return to its 

original speed once the control sticks return to center.

 Continues 

In this position the aircraft will maintain its speed of flight however if you accelerate or slow down, it will 

continue flying at the new speed once the control sticks return to center.

(1) Cruise Control only works in GPS-ATTI mode (GPS > 6).

(2) The aircraft will exit Cruise Control mode and hover at its current altitude when less than 6 GPS 

satellites are detected, switches to ATTI. mode or enters auto go home mode. To enter“Set” and 

“Continue” modes, you must first go into “OFF” mode.

(3) Cruise Control is disabled during Banked Turn mode flying.

(4) Maximum speed is 15m/s under Cruise Control mode.

4.2 Servo Gimbal function 

Connect the servos of your gimbal to the Controller Unit as the fig. below,roll servo connects to F3 port and 

pitch servo connects to F2, and configure in Advanced->Gimbal page in the Assistant software. No Receiver

channel is asked to be mapped for the F2 or F3 port if gimbal function is enabled in the Assistant Software.

Note: Even you map Receiver channels to F3 and F2 (Which are shown as D3 and D2 in the Assistant Software

-> Channel Mapping), the F3 and F2 will not give output signals from the mapped Receiver channels.

4.3 Flight Limits 

All unmanned aerial vehicle (UAV) operators should abide by all regulations from such organizations as the ICAO 

(International Civil Aviation Organization) and their own national airspace regulations. For safety reasons, the flight 

limits function is enabled by default to help users use this product safely and legally. The flight limits function 

includes height, distance limits and safety zone.

In Ready to Fly mode, height, distance limits and No Fly Zones work together to manage flight. In Ready to Fly

(non-GPS) status, only height limits applies and flights cannot go higher than 120m.

Default parameters in Assistant Software are compliant within the definitions of class G ruled by ICAO. 

(Refer to Airspace Classification to get more details). As each country has its own rules, make sure to 

configure these parameters to comply with these rules before flying.

4.3.1 Max Height, Radius Limits & Home Fence

The Max Height & Radius restricts the flying height and distance. Configuration can be done in the A2 Assistant. 

Once complete, your aircraft will fly in a restricted cylinder.

Max Radius No limits 

(1) If you fly out of the limit, you can still control the aircraft, but cannot fly it further. 

(2) If the aircraft flies out of the max radius in ATTI mode, it will fly back within range automatically.

Home fence is a safety feature that prevents the aircraft from coming in too close to an operator. When enabled, 

the aircraft will not be able to enter a safe area defined by the user.

Application examples:

1. Supply safe guard for new users in case of damage from wrong operation.

2. Keep users safe when aircraft flies close in a high speed.

The safety radius can be set in the A2 Assistant as shown below:
©2013-2014 DJI. All Rights Reserved. 41

 

Assign a switch on the remote control to turn the home fence feature on and off. The safety radius range can 

be set between 12m and 100m.

(1) Home fence feature works only with GPS-ATTI mode. NO home fence limit for ATTI mode and 

navigation mode.

(2) Failsafe procedure overrides the home fencing feature. 

4.3.2 Flight Limits of Special Areas

Restricted areas include airports worldwide. All restricted areas are listed on the DJI official website at 

http://www.dji.com/fly-safe/category-mc. Restricted areas are divided into category A and category B. Category A 

areas cover major international airport such as LAX and Heathrow, while category B areas includes smaller airports.

Category A Safety Zone 

 The category A “safety zone” is comprised of a small “no-fly zone” and a range of “restricted-altitude zones”. 

Flight is prevented in the “no-fly zone” but can continue with height restrictions in the restricted-altitude zone.

 1.5 miles (2.4 km) around a designated safety zone is a no-fly zone, inside which takeoff is prevented. 

 1.5 miles (2.4 km) to 5 miles (8 km) around restricted areas are altitude restricted, with maximum altitude going 

from 35 feet (10.5 m) at 1.5 miles (2.4 km) to 400 feet (120 m) at 5 miles (8 km).

 A “warning zone” has been set around the safety zone. When you fly within 320 feet (100m) of the safety zone, a 

warning message will appear on the DJI Ground Station.

and then connect the gear to the F1 port.

(2) The Gear channel is required to be mapped with a channel on Receiver if the Intelligent Gear 

function is enabled in Assistant Software, and the F1 port will give outputs for retracting control.

(3) Once you map the Gear channel, F1 port will give output signals from the controller for retract 

control. Otherwise, even the Intelligent Gear function is enabled; F1 will give output from D1 (it’s 

necessary to map the D1 channel with a channel on Receiver as your demands).

4.6 Attitude Control When One Motor Output Fails 

For Hexa-rotor, including Hexa-rotor I, Hexa-rotor V, Hexa-rotor IY and Hexa-rotor Y, the aircraft with A2 flight 

control system is attitude controllable when one motor output fails.

Select Course lock or home lock mode for flying the aircraft into a safe area to land when the aircraft is 

far away or the attitude can’t be recognized.
