Dear	Sir	or	Madam:	

Attached,	please	find	Sentera, LLC’s request	for	an	exemption	from	certain	stated	Federal	

Aviation	Regulations	to	allow	commercial	operation	of	its	small	unmanned	aircraft	systems	

(hereafter	referred	to	as	“SUAS”	or	“Drone”)	for	the	purposes	of	aerial	photography,	

cinematography,	videography,	mapping,	crop	surveying,	inspections	and	other	flight	

operations,	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 of	the FAA	

Modernization	and	Reform	Act	of	2012.

Please	be	advised	that	the	FAA	has	previously	issued	grants	of	exemption	in	circumstances	

similar	in	all	material	aspects	to	those	requested	in	this	petition,	most	recently	in	

Exemption	Nos.	11442	to	HAZON	Solutions,	11157to	Likeonatree	Aerial and	in	11446	to	

Trumbull	Unmanned	LLC – including	the	specific	SUAS	to	be	operated.	Therefore,	Sentera,	

LLC	respectfully	requests	this	exemption	be	considered	under	the	“summary	grant”	process.

As	detailed	in	this	document,	a	granted	exemption	would	permit	the commercial operation	

of	SUAS	under	controlled	conditions in	airspace	that	is	limited and	controlled	via	

subsequent	COA	applications.	Predominantly,	Sentera,	LLC	seeks	to	operate	under	the	

“Blanket	200ft	COA”	guidance	that	was	issued	by	the	FAA	in	March	2015	and	respectfully	

requests	the	“Blanket 200ft COA”	be	granted	in	concert	with	these	exemptions.

The	requested	exemptions	and	proposed limitations	provide	for	at	least	an	equivalent	or	

higher	level	of	safety	to	operations	under	the	current	regulatory	structure,	specifically	

safety	enhancements	to	personnel	climbing	vertical	infrastructure	and create	a	low-risk	

alternative	to	certain manned	aviation	operations.

As	outlined	in	this	request	for	exemption,	the	SUAS	Sentera, LLC proposes	to	use	are:

DJI	Phantom II, III

DJI	Inspire I

If	I	can	provide	any	additional	information	in	support	of	your	review	of	this	petition,	please	

do	not	hesitate	to	call	me	at	952-242-9241 or	send	an	email	to	reid.plumbo@sentera.com.

Sincerely,

Section	1:	Introduction	&	Interest	of	Sentera,	LLC

Sentera,	LLC	is	a	developer	of	precision	sensing	solutions	for	the	industrial,	commercial	and	

agricultural	markets. The	staff	and	leadership	at Sentera,	LLC	offer	over	100	years	of	

experience	in	the	SUAS	industry	and	have	flown	several-thousand	flight	hours	on	various	

UAS	systems.	This	team	has	deep	experience	in	SUAS	airspace	integration,	airworthiness	

and	flight	operations,	including	the	successful	award	of	an	SUAS	airworthiness	certificate	

issued	by	the	British	Military.	Sentera,	LLC	also	has	on	staff	a	professional airman	holding	

CFI,	CFII	and	MEI	certificates	with	nearly	3,000hrs	of	flight	experience,	including	over	900	

hours	of	multi-engine	flight	instruction.	Sentera,	LLC’s	has	the	background	and	team	to	

safely	integrate	within	the	NAS	and	provide	low-risk,	cost-effective	airborne	data	and	

photography	to	its	customers.

Sentera,	LLC	proposes	to	commercially	operate	its	DJI	SUAS	platforms	for the	purposes	of	

aerial	inspections,	crop	and	agricultural	surveys,	aerial	photography,	videography,	data	

collection	and	other	flight	operations	conforming	to	the proposed limitations	and	

restrictions.	Sentera,	LLC	holds	that	commercially	operating	an	SUAS within	the	NAS	under	

these same	limitations	and	restrictions	will	not	pose	a	hazard	to	manned	aircraft,	and	that	

operation	of	its	SUAS	is	in	the	public	best	interest	by	providing	an	inexpensive,	low-risk	

alternative	to	manned	survey	operations.

Section	2:	Regarding	the	Unmanned	Aircraft	System

The	FAA’s	public	guidance	on	filing	an	exemption	under	Section	333	is	reprinted	below.	

This	section	intends	to	fulfill	each	requirement	of	this	guidance.

1.	Petitioners	should	describe	how	the	proposed	UAS	operation	will	be	safely	conducted	to	

minimize	risk	to	the	NAS	or	to	persons	and	property	on	the	ground.	Specifically,	petitioners	

should	describe	the	design	and	operational	characteristics	for	the	type(s)	of	UAS	they	intend	to	

operate,	e.g.	aircraft	performance	and	performance	limitations,	operating	procedures,	and	

aircraft	loading	information	in	as	much	detail	as	possible.	This	could	be	provided	in	the	

petition	or	in	an	Aircraft	Flight	Manual	or	similar	document.

NOTE:	The	FAA	will	consider	all	information	and	data	submitted	by	the	petitioner	that	

describes	the	UAS	developmental	and	operational	history.	This	could	include	statistical	data	or	

other	documentation	for	the	specific	design	and	performance	characteristics	of	the	UAS,	

including	the	operational	history	and	operational	failure	modes,	obtained	through	previous	

Research	&	Development	(R&D)	and/or	flight	test	activities,	e.g.	operations	conducted	under	a	

COA,	with	a	civil	airworthiness	certificate,	or	under	other	authorized	operating	conditions.

2.	Petitioners	should	describe	any	procedures	they	would	implement,	such	as	pre-flight	

inspections,	maintenance,	and	repair,	to	ensure	that	the	UAS	is	in	a	condition	for	safe	flight.	

This	could	be	provided	in	the	petition,	an	Aircraft	Flight	Manual,	a	Maintenance	and	

Inspection	Manual,	or	similar	document.

NOTE:	The	Aircraft	Flight	Manual	and	Maintenance	and	Inspection	Manual	may

be	separate	documents	or	combined	in	a	single	document.

3.	The	petitioner	should	describe	the	Radio	Frequency	(RF)	spectrum	used	for	control	of	the	

UAS	and	associated	equipment	that	is	part	of	the	UAS	(i.e.,	sensors,	cameras,	etc.),	and	whether	

it	complies	with	Federal	Communications	Commission	(FCC)	or	other	appropriate	government	

oversight	agency	requirements.
3

NOTE:	Petitioners	should	be	able	to	provide	the	FCC	approval	letter	or	show	compliance	with	

FCC	requirements	upon	request.

Sentera,	LLC	intends	to	commercially	operate	SUAS	weighing	less	than	10lbs,	during	

daylight	hours,	within	visual	line	of	sight	of	the	PIC,	at	altitudes	less	than 400ft	AGL and	at	

speeds	less	than	35mph.	As	described	later,	Sentera	PICs	shall	be	fully	qualified	airmen,	

holding	at	least	a	sport	pilot	certificate	and	associated	medical	clearance. The	proposed	

SUAS	are	equipped	with	GPS-enabled	autopilots,	capable	of	safe,	steady	autonomous	flight	

and	guided	by	the	PIC.	The	proposed	SUAS	are	commercially	available,	“off	the	shelf”	

products	that	have	accumulated	innumerable	flight	hours	across	the	world,	and	they	have	

proven	themselves	low-risk,	safe	aircraft.	Given	the small	size	and	weight,	low	altitudes,	

slow	speeds,	a	qualified	PIC,	a	GPS-equipped	autopilot,	data-link	and	countless	flight	hours,	

Sentera,	LLC	holds	that	commercially	operating	these	SUAS	under	the	limitations	and	

restrictions	set	forth	is	a	safe	alternative	to	the	current	regulatory	structure	and	minimizes

risk	to	the	NAS	or	to	persons	and	property	on	the	ground.

2.1	Proposed	SUAS

Sentera,	LLC	intends	to	operate	the	DJI	Phantom	and	Inspire	family	of	SUAS,	with	

the	ability	to	conduct	vertical	takeoffs and	landings,	hover,	and	carry	payloads such	

as	cameras,	sensors	and	other	equipment	necessary	to	complete	its	aerial	

photography,	cinematography,	videography,	mapping, crop	surveying	and	

inspection	tasks.	Each	SUAS	is	described	below.

DJI	Phantom

The	Phantom	system	is	comprised	of	a	four-rotor	unmanned	aircraft	and	

handheld	controller,	which	is	responsible	for	both	operation	and	camera	

functions.	The	maximum	gross	weight	of	the	Phantom	is	1250g,	and	it	

measures	350mm	across	rotor-to-rotor.		Its	maximum	horizontal, ascent	and	

descent	speeds	are	15	m/s,	6m/s	and	2m/s	respectively. The	Phantom	is	

powered	with	a	Lithium	Ion	battery	and	flies	for	approximately	20	minutes.	

More	detailed	specifications	are	available	in	the	DJI	Phantom	Operations	

Manual,	which	is	attached	as	Appendix	1.

DJI	Inspire

The	Inspire	system	is	comprised	of	a	four-rotor	unmanned	aircraft	and	

handheld	controller,	which	is	responsible	for	both	operation	and	camera	

functions.	The	maximum	gross	weight	of	the	Inspire	is	3000g,	and	it	

measures	438	x 451	x	301mm.	The	Inspire’s	maximum	horizontal,	ascent	

and	descent	speeds	are	22m/s,	5m/s	and	4m/s	respectively. The	Inspire	is	

powered	by	a	Lithium	Ion	battery and	flies	for	approximately	20	minutes.	

More	detailed	specifications	are	available	in	the	DJI	Inspire	Operations	

Manual,	which	is	attached	as	Appendix	2.

2.2	 Maintenance &	Inspection

Sentera,	LLC	shall	follow	the	manufacturer’s	maintenance,	overhaul,	

inspection	and	record-keeping guidelines	as	specified	in	both	the	

maintenance	manual	and	operations	manual,	attached	as	Appendices 1,	2	

and	3. Sentera,	LLC	will	conduct	inspections	and	maintenance,	which	shall	

be	noted	in	the	aircraft’s	logbook	including	total	flight	hours	and	the	nature	

of	maintenance	performed. Comprehensive	maintenance	will	be	performed	
4

after	every	200	flights	or	50	flight hours	– whichever	is	earliest	– in	

conformance	with	the	manufacturer’s	guidelines.

In	advance	of	every	flight	operation,	the	Pilot	In	Command	(PIC)	will	

thoroughly	inspect	the	SUAS	to	ensure	it	is	safe	to	fly	as	described	in	

Appendix	3.	Furthermore,	the	PIC	will	conduct	a	pre-flight	checklist	as	

described	in	the	Operations	Manual.	With	both	inspections	completed	and	

passed,	the	SUAS	shall	be	deemed	safe	to	fly.

All	SUAS	proposed	under	this	request	for	exemption	will	be	in	compliance	

with	all	manufacturer	maintenance,	system	and	safety	bulletins.

2.3 Radio	Communications

All	radio	systems	used	in	the	proposed SUAS	comply	with	FCC	regulations	

and	have	earned	FCC	approval.	Sentera,	LLC	shall	operate	the	SUAS	in	

compliance	with	those	approvals.	Certificates	of	compliance	may	be	found	in	

Operations	manuals	in	Appendices	1	and	2.

Both	the	Phantom	and	Inspire	SUAS	operate	in	two	different FCC-approved

bands.	The	remote	control	operates	between	5.728	and	5.85GHz,	and	the

video/data	link	operates	between	2412MHz	and	2462MHz.

Section	3:	Regarding	the	Unmanned	Aircraft	PIC

The	FAA’s	public	guidance	on	filing	an	exemption	under	Section	333	is	reprinted	below.	

This	section	intends	to	fulfill	each	requirement	of	this	guidance.

Regarding	the	Unmanned	Aircraft	PIC

4.	Petitioners	should	describe	the	qualifications	required	of	any	PIC(s)	who	will	be	directly	

responsible	for	the	operation	of	the	UAS,	including	information	such	as:	the	level	of	airman	

certificate	held;	any	applicable	training	related	to	the	operation;	and	any	minimum	hours	of	

flight	experience	required	by	the	PIC(s),	both	total	flight	time	and	the	time	with	the	particular	

UAS.	If	the	operation	would	use	visual	observers,	petitioners	should	describe	their	roles	and	

qualifications.

5.	Petitioners	should	describe	the	medical	standards	and	certification	of	the	PIC(s)	directly	

responsible	for	the	operation	of	the	UAS.

Sentera,	LLC	PICs shall	possess	a	current	airline	transport,	commercial,	private,	recreational	

or	sport	pilot	certificate.	The	PIC	shall	also	hold	a	current	FAA	airman	medical	certificate	or	

a	valid	U.S.	Driver’s	License.	The	PIC	shall also	meet	the	flight	review	requirements	specified	

in 14	CFR	§	61.56	in	an	aircraft	in	which	the	PIC	is	rated	on	his	or	her	pilot	certificate.

Prior	to	commercial	operations,	Sentera,	LLC	PICs	shall	have	accumulated	and	logged	a	

minimum	of	25	hours	total	time	as	an	SUAS	pilot.	Flights	for	the	purposes	of	training	

Sentera,	LLC’s	PICs	and	VOs	(training,	proficiency,	and	experience-building)	and	

determining	the	PIC’s	ability	to	safely	operate	the	UAS	in	a	manner	consistent	with	how	the	

UAS	will	be	operated	under	this	exemption, are	requested	under	the	terms	of	this	

exemption.	Training	operations	shall	only	be	conducted	during	dedicated	training	sessions.	

During	training,	proficiency,	and	experience-building	flights,	all	persons	not	essential	for	
5

flight	operations	shall	be	considered	nonparticipants,	and	the	PIC	shall	operate	the	UA	with	

appropriate	distance	from	nonparticipants	in	accordance	with	14	CFR	§	91.119.

Section	4:	Regarding	the	Operation	of	the	Unmanned	Aircraft

The	FAA’s	public	guidance	on	filing	an	exemption	under	Section	333	is	reprinted	below,	

along	with	Sentera,	LLC’s	proposal.	This	section	intends	to	fulfill	each	requirement	of	this	

guidance.

Regarding	the	Operation	of	the	Unmanned	Aircraft

6. Petitioners	should	fully	describe	their	intended	UAS	operation(s).	Petitioners	should	

describe	how	the	proposed	operation(s)	would	not	adversely	affect	safety,	or	how	they	

would	provide	a	level	of	safety	at	least	equivalent	to	that	provided	by	the	rule	from	

which	exemption	is	sought.	Petitioners	should	address	any	plans	to	implement	clearly	

defined	operational	borders	and	procedures	to	ensure	public	safety,	which	includes	

persons	and	property	both	in	the	air	and	on	the	ground.	This	can	be	described	in	the	

petition,	in	an	Operations	Manual,	or	similar	document.		NOTE:	The	FAA	will	closely	

examine	the	proposed	operation(s)	with	respect	to	safety	of	flight,	NAS	safety	

considerations,	and	the	safety	of	the	non-participating	persons	and	property	during	

the	operational	period	and	within	the	operational	area.		

7. Petitioners	should	specify	the	proposed	maximum	operating	speed	and	altitude,	and	

describe	minimum	flight	visibility	and	distance	from	clouds	for	their	intended	

operation(s).	Petitioners	should	describe	potential	hazards	and	safety	mitigations	

associated	with	these	proposed	conditions.	These	issues	can	be	addressed	in	the	

petition,	an	Operations	Manual,	or	similar	document.		

The	SUAS	will	be	operated	during	daylight hours,	in	compliance	with	visual	flight	rules,	and	

flown	within	direct	visual	line	of	sight	of	the	PIC	at	all	times and	never	over	congested	or	

densely	populated	areas	unless	specifically	authorized	by	the	Air	Traffic	Organizationissued	COA.	The	PIC	shall	use	human	vision	unaided	by	any	device	other	than	corrective	

lenses,	as	specified	on	the	PIC’s	FAA-issued	airman	medical	certificate	or	U.S.	driver’s	

license.

The	SUAS	shall	be	operated	at	an	altitude	of	no	more	than	400ft	AGL,	unless specifically	

authorized	and	operating	under	the	terms	of	the	COA,	at	speeds	less	than	15m/s	(34mph).	

The	SUAS	will	not	be	operated	less	than	500ft	below	or	less	than	2000ft	horizontally	from a	

cloud, or	when	visibility	is	less	than	3	statute	miles.

Prior to	beginning	a	flight,	the	PIC	shall	clearly	establish	the	limits	in	latitude,	longitude	and	

altitude	AGL	to	ensure	compliance	with	the	COA	under	which	the	SUAS	is	flown	and	

establish	the	“sterile	area”	for	operations.	If	at	any	time,	this	area	is	breached	by	

unpredicted	obstacles	(manned	aircraft	or	otherwise),	the	PIC	shall	abort	the	flight.	Manned	

aircraft	shall	have	right	of	way	at	all	times.

In	case	of	a	reduced	or	diminished	control link,	the	SUAS	will	automatically	return	to	a	

predetermined	point	within	the	private	or	controlled-access	property.

The	PIC	shall	not	begin	a	flight	unless	there	is	sufficient	available	power	for	the	SUAS	to	

complete	the	intended	mission	and	to	operate	for	at	least	five	minutes	after	that.

By	operating	within	the	limitations	and	guidelines	set	forth	herein,	Sentera,	LLC	shall	

provide	an	equivalent	level	of	safety	to	operations	under	the	existing	regulatory	structure.
6

8. Petitioners	should	describe	the	characteristics	of	the	area	of	intended	operation(s)	and	

the	associated	potential	hazards,	in	accordance	with	the	statutory	mandate	under	

Section	333		regarding	proximity	to	populated	areas.	These	issues	can	be	addressed	in	

the	petition,	an	Operations	Manual,	or	similar	document.	

9. Petitioners	should	describe	if	they	intend	to	operate	in	the	proximity	of	any	airports,	in	

	accordance	with	the	statutory	mandate	under	Section	333	regarding	proximity	to	

airports.		

All	flight	operations	will	be	conducted	at	least	500ft	from	all	nonparticipating	persons,	

vessels,	vehicles	and	structures	on	private	or	controlled	access	property	with	permission	

from	the	property	owner/controller	or	authorized	representative.	In	some	cases	due	to	

mission	requirements,	the	SUAS	will	be	operated	closer	than	500ft	to	commercial	and	

industrial	infrastructure	and	facilities.	In	these	instances,	Sentera,	LLC	shall	have	the	

authorization	of	the	property	owner/controller	or	from	an	authorized	representative,	and	

the	PIC	shall	have	conducted	a	safety	assessment	and	determined	that	it	does	not	present	an	

undue	hazard.	Permission	from	the	property	owner/controller	or	authorized	

representative	will	be	obtained	for	each	flight	to	be	conducted.	

Flight	operations	will	not	take	place	with	5nm	of	airport	unless	a	letter	of	agreement	with	

that	airport’s	management	is	obtained and/or	otherwise	permitted	by	an	Air	Traffic	

Organization-issued	COA.

Foreseen	hazards	include encroachment	of	manned	aviation	operations	and	nonparticipants	on	the	ground.	Both	of	these	hazards	are	mitigated	by	choice	of	location	(noncongested	areas) and	strict	limits	on	range	(visual	line	of	sight)	and	altitude	established	

herein. Operation	under	these	limits	effectively	mitigates	these	risks.

10. The	UAS	must	be	operated	within	visual	line-of-sight	(VLOS),	in	accordance	with	the	

	statutory	mandate	under	Section	333(b)(1).	Petitioners	should	describe	how	they	

intend to		comply	with	his	mandate.		

11. Petitioners	should	describe	any	procedures	they	would	implement	for	conducting	a	

preflight	safety	risk	assessment	to	determine	that	the	UAS	is	in	a	condition	for	safe	

flight	(14	CFR	§	91.7(b))	and	that	the	planned	operation can	be	completed	safely.	

These	procedures	can	be	addressed	in	the	petition,	an	Aircraft	Flight	Manual,	

Operations	Manual,	or	similar	document.		

As	described	above,	The	SUAS	will	be	operated	during	daylight hours,	in	compliance	with	

visual	flight	rules,	and	flown	within	direct	visual	line	of	sight	of	the	PIC	at	all	times.	The	PIC	

shall	use	human	vision	unaided	by	any	device	other	than	corrective	lenses,	as	specified	on	

the	PIC’s	FAA-issued	airman	medical	certificate	or	U.S.	driver’s	license.

In	advance	of	every	flight	operation,	the	Pilot	In	Command	(PIC)	will	thoroughly	inspect	the	

SUAS	to	ensure	it	is	safe	to	fly	as	described	in	Appendix	1-5	and	Appendix	7.	Furthermore,	

the	PIC	will	conduct	a pre-flight	checklist	as	described	in	Appendix	1 and	2,	and	ensure	the	

planned	operation	can	be	completed	safely	with	sufficient	battery	reserves (including	wind	

and	terrain	limitations).	With	both	inspections	completed	and	passed,	the	SUAS	shall	be	

deemed	safe	to	fly.

12. If	petitioners	intend	to	conduct	operations	which	have	existing	requirements	to	notify	

Flight	Standards	District	Offices	(FSDOs)	prior	to	operations	– such	as	motion	picture	
7

and	television	filming,	or	pipeline	and	powerline	patrol	– petitioners	should	describe	

their	intended	coordination	in	this	regard	for	their	proposed	operation(s).		

Sentera,	LLC’s	aerial	infrastructure	inspections,	cinematography/videography	or	

agricultural	operations	do	not	require	notification	to	FSDOs.

13. The	FAA	intends	to	require	entities	who	obtain	an	exemption	under	this	process	to	also	

obtain	a	Certificate	of	Waiver	or	Authorization	(COA)	from	the	FAA	Air	Traffic	

Organization	prior	to	conducting	operation(s)	in	the	NAS.	The	COA	application	is	

available	here.

As	stated	previously,	Sentera,	LLC	shall	obtain	an	Air	Traffic	Organization-issued	COA	prior	

to	conducting	any	operations	under	this	requested	grant	of	exemption.	Sentera,	LLC	seeks	

primarily	to	operate	under	the	“Blanket	200ft	COA”	guidance	offered	by	the	FAA	in	March,	

2015	and	respectfully	requests	that	COA	be	issued	concurrently	with	these	exemptions.	For	

operations	not	conforming	to	the	“Blanket	200ft	COA”	guidance,	Sentera,	LLC	will	seek	

separate	and	additional	COAs	to	operate	its	SUAS.

Section	5:	Requested	Exemptions

SUAS	Flight	Manual,	and	operational	

instruction	material	at	the	location	of	

the	PIC	and/or	Ground	Station. The	FAA	

has	previously	determined	that,	given	

this,	relief	from	this	requirement	is	not	

necessary.

91.103 Preflight	Action Sentera,	LLC	will	perform.	Relief	is	not	

necessary.

91.105 Flight	Crewmembers	at	

Stations

No	human	will	be	aboard	the	SUAS	

operated	by	Sentera,	LLC,	however,	the	

FAA	has	held	in	previous	petitions	that	

relief	is	not	necessary.

91.109(a) Flight	Instruction Sentera,	LLC	will	conduct	flight	training	

in	accordance	with	the	guidance	and	

limitations	offered	in	this	document,	as	

well	as	the	Operations	&	Flight	Manuals	

attached	as	appendices	to	this	

document.	The	FAA	has	held	in	previous	

petitions	that	relief	is	not	necessary.

91.119 Minimum	Safe	Altitudes Request	relief	within	limitations	and	

restrictions	proposed	herein,	specifically	

in	Section	4.

91.121 Altimeter	Settings Each	of	the	SUAS	Sentera,	LLC	proposes	

to	operate	measure	altitude	with	both	

barometric	pressure	sensors	and	GPS.	

Prior	to	each	flight,	the	barometric	

altimeter	will	be	set	to	0ft	AGL	instead	of	

the	setting	of	the	nearest	reporting	

station.	Sentera,	LLC	holds	that	by	

counting	altitude	in	AGL,	zeroed	at	the	

point	of	departure,	will	ensure	

conformance to	the	COA	restrictions	

under	which	the	SUAS	is	operating.	

Given	the	low	operating	altitudes	of	

system	and	operating	within	the	

proposed	restrictions,	relief	is	

requested.

91.151 Fuel	Requirements	in	VFR	

Conditions

As	described	in	this	document,	the	SUAS

Sentera,	LLC	proposes	to	operate	have	

total	endurance	of	between	20	and	30	

minutes.	Sentera,	LLC	will	ensure	

missions	are	conducted	with	sufficient	

reserve	to	operate	for	at	least	five	

minutes	after	the	intended	mission	is	

complete.	The	short	flight	time	makes	

the	reserves	specified	in	91.151	

impractical	and	therefore	relief	is	

requested.

91.203 Certifications	Required Sentera,	LLC	will	place	these	documents	
9

at	the	location	of	the	ground	station	

and/or	with	the	PIC.	The	FAA	has	

previously	held	that	this	is	sufficient	to	

provide	an	equivalent	level	of	safety,	and	

therefore,	relief	is	requested.

91.405 Maintenance	Required Relief	is	requested	within	the	limitations	

and	conditions	set	forth	in	Section	2.2	of	

this	document.

91.407 Operation	After	Maintenance Relief	is	requested	within	the	limitations	

and	conditions	set	forth	in	Section	2.2	of	

this	document.

91.409 Inspections Relief	is	requested	within	the	limitations	

and	conditions	set	forth	in	Section	2.2	of	

this	document.

91.417 Maintenance	Records Relief	is	requested	within	the	limitations	

and	conditions	set	forth	in	Section	2.2	of	

this	document.

Section	6:	Public	Interest &	Equivalent	Level	of	Safety

Though	this	is	addressed	in	pieces	of	this	petition,	a	more	complete	answer	is	provided	in	

this	section.

Sentera,	LLC	proposes	certain	14	CFR	exemptions	to	allow	commercial	operation	of	its	

small	unmanned	aircraft	systems	for	the	purposes	of	aerial	photography,	cinematography,	

videography,	mapping,	crop	surveying,	inspections	and	other	flight	operations,	so	long	as	

such	operations	are	conducted	within	and	under	the	conditions	outlined	herein.	

Traditional	agricultural	operations	such	as	crop	inspections	and	data	collections	under	the	

current	regulatory	structure	include	the	use	of	manned	aircraft,	which	are	expensive,	

inefficient	and	cannot	be	safely	operated	in	close	proximity	to	the	ground.	By	using	Drones	

to	complete	these	missions	the	public	interest	is	served	by	increasing	safety	to	pilots,	

passengers	and	non-participants	on	the	ground.	

Traditional	industrial	infrastructure	inspection	operations	under	the	current	regulatory	

structure	are	often	performed	1)	from	the	ground,	where	high	detail	is	impossible	2)	by	a	

climber	at	great	risk	to	his	or	her	personal	safety,	or	3)	by	a	manned	aircraft	where	flying	

close	to	elevated	infrastructure	is	extremely	dangerous,	and	not	permitted	by	14	CFR	

91.119.

Grant	of	exemption,	with	the	conditions	and	limitations	set	forth	herein, to	Sentera,	LLC	will	

provide	for	at	least	an	equivalent	or	better	level	of	safety,	reduce	risk	to	life	and	property,	

thereby	serving	the	public	interest.
