Dea r Sir or Madam

,

Pursuant to S e c tio n 33 3 of th e FAA Mo derniz atio n & Refo rm Act an d 1 4 C.F.R. Part 11

, Eagle Eye Photography hereby ap pli es f or t he g rant of

exemption from certain Federal Aviation Regulations for our 3 separate Unmanned Aircraft

System UAS quadrotor aircraft owned and operated exclusively by Eagle Eye Photography.

T h e requeste d e x e mption w ould su p p o rt a n application f or a com m ercial Certi f ica te (s) o f

Authoriz ation (C OA) to u se our Yuneec Q500, Yuneec Q500+ and DJI Inspire 1

aircraft to support real estate photography, videography, and reporting

for commercial purposes.

Eagle Eye also wants to provide support for local law enforcement and

emergency services.

T h e Yuneec Q500 and DJI Inspire 1 Unmann ed Air cra f t Sy stem s (UA S) are lig h tw e ig ht

(less than 6 lb), battery operated, quadcopter aircraft with onboard camera, gimble

and GPS and are remotely controlled via 2.4ghz communications equipment.

All 3 Aircraft (2 Q500 & 1 Inspire 1) owned and operated by Eagle Eye have

multiple safety features built in. In case of lost communication with it's transmitter,

the UAS will automatically return to it's launch point and land itself if necessary.

Each UAS also keeps flight record data recorded and stored on SD memory

cards in the transmitter. Each UAS uses multiple satellites for their GPS signal

and constantly feeds the PIC location data such as altitude direction and distance

of travel.

T h e Yuneec and DJI Inspire 1 UAS each carry an onboard high definition video and still

camera system that allows it to perform aerial photography, videography, and searches.

By ap p ro v ing the e x e mption, Eagle Eye's UAS o perations w i ll crea te benef its t o

both the e c o n omy an d the environm ent w hich are u ltim ately in t h e public inte rest.Original 06/09/ 2015 Page 2

All Unmanned Aerial Systems will be operated with both a Pilot in Charge

and a Visual observer in accordance with the following restrictions:

All o perations w il l occur a t no more than 400' AGL

- The aircra f t w ill be ope rated w ith the p e r m i ssion o f the property ow ner

- W h e n necessary, app li cable permits w ill be acq uir ed f ro m loc a l auth o rities

- The aircra f t w ill not b e o perated ov e r urban or po p ulated a reas

- The aircra f t w ill not b e o perated at air shows or ov er an open -air a ssem bly of people

- The aircra f t w ill not b e o perated ov e r he av il y t raff icked roads

- Op erations w il l b e lim ite d t o da y , v isua l m e te orological con d itio ns

- A ircr af t w il l rem a in w ithin Vis ual Line o f Sig h t a t n o g rea t er th an 1 /2 NM o f t h e PIC at

all time

- W h il e t he aircr aft is ai rborne, th e V O w ill be po sition ed w it hin voice distance to the PIC

- W h e n n ecessary a nd ap plicable, Eagle Eye w il l f ile a NOTAM

providing radial/DME, radius, and a date/time group for each operation

For ce rtain co mplex op e ratio ns, Eagle Eye may assign one or t w o se nsor/sof tw are

operato rs or VO's to assist t h e operations.

We submit that our choices of UAS and knowledge of FAA

Unmanned Aircraft Systems (UAS) Regulations & Policies help to show our

commitment to safety and compliance while striving to provide a valuable service

to the public.

-The DJI Inspire 1 and Yuneec Q500 UAV’s lig ht weight, reliability and historically

safe operation, while having received multiple approvals for section 333 petitions,

make these excellent choices for UAS.

-We maintain a fully q ualif ied and trained flight crew

. -Eagle Eye will only operate under the guidelines established within the grant and

our operations will have an equivalent or greater level of safety than manned

aircraft performing the same mission.
