Dear Sir or Madam,

Pursuant to Section 333 of the FAA Modernization and Reform Act o f 2012 (the Reform Act) and 14 C.F.R. Part 11, NEC Laboratories America, equipped to conduct aerial imaging and data collection, as well as testing implementation of our proprietary mobile aerial public announcement platfo rms , hereby apply for an exemption from the listed Federal Aviation Regulations (“FARs”) to allow commercial operation of our sUASs, so long as such operations are conducted within and under the conditions outlined herein or as may be established by the FAA as requires by Section 333.
I, Ting Wang , Department Head of Optical Networking and Sensing of NEC 

# Laboratories America, Inc. ( NEC 

# Laboratories) , hereby agree to abide by all regulations pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 and 14 C.F.R. Part II

. NEC 

# Laboratories is the US

- based division of NEC’s global network of research laboratories. Our primary focus is on technology research and early market validation in support of NEC’s core businesses globally and in the US. NEC 

# Laboratories is investigat ing state

# Laboratories proposes to conduct research and development of scientific sensing platforms with integration of sUA S by using DJI S1000 plus, DJI Inspire, DJI Matrice M100, Harris H18 Pro and STARK H6 & Hx8 multirotors in the continental United States 

# in support of current research projects including public safety prevention (i.e. gas leak detection and public addressi ng system) and public health monitoring (i.e. air quality monitoring) in real time

. No tools as powerful and convenient as the sUAS technology have been available to our process with high flexibility to easily and quickly attain a sensing survey data witho ut any blind angles. This provides major benefits for detection of gas leakage from gas delivery pipelines and real

- time air quality monitoring. Before the use of UAV

# technology, it was difficult to monitor gas leakage along the pipelines and obtain air

qu ality results in 3D. The 3D air quality model is the key to investigat ing and understand air pollution. Furthermore, the UAV technology will provide high mobility with wide coverage in the applications of public addressing. The use of UAV technology is key to our success in detecting gas leakage of pipelines and obtaining 3D air quality results that are important for public safety prevention and air pollution investigations.

As described more fully below, the request exemption would permit the op eration of small, unmanned, and redundant sUAS under controlled conditions in airspace that is 1) limited 2) predetermined 3) controlled as to access and 4) would provide safe operations and affordability to the existing real estate and closed

- set special event industries currently using conventional aircraft. Approval of this exemption would thereby enhance safety, promote industry growth and fair competition through affordability of aerial photography and cinematography and fulfill the Secretary of Transp ortation’s (the FAA Administrator’s) responsibilities to “... establish requirements for the safe operation of such aircraft systems in the national airspace system.” Section 333 of the Reform Act.

NEC Laboratories requests that the publication a nd comment procedures be waived in accordance with 14 C.P.R.§ 11.87 which states:
§ 11.87 . A re there circumstances in which FAA may decide not to publish a summary of my petition for exemption? The FAA may not publish a summary of your petition for exemp tion and request

# comments if you present or we find good cause why we should not delay action on your

petition. The factors we consider in deciding not to request comment include:
a)

. Whether granting your petition would set a precedent. b)

. Whether the relief requested is identical to exemptions granted previously. c)

. Whether our delaying action on your petition would affect you adversely. d)

. Whether you filed your petition in a timely manner.
Corresponding to the above sub

- sectio ns, NEC Laboratories has good cause to request the FAA to waive the comment period and not delay action on the petition because: (a) NEC Laboratories would not se t any precedent. Exemption #'s 11359, 11358, and 11425 are all p reviously granted petitions to a llow the petitioner to operate an unmanned aircraft system (UAS) to conduct aerial imaging and data collection activities. NEC Laboratories agrees to abide by the same limitations set forth by these exemptions. (b) This petition for exemption is requesting re lief similar to the above

- mentioned petitioners. The regulations that NEC Laboratories is seeking relief from were chosen based directly upon the FAA's chart included in the exe mptions mentioned above. This was done so that the FAA could waive the comment period and rapidly grant this petition. (c) Delaying the granting of this petition would adver sely affect the public, the FAA , and NEC Laboratories . Both the Public and the FAA would be better served by the FAA quickly granting this petition and thereby free ing up limited FAA resources and allowing FAA inspectors to dedicate their time and attention to much higher priorities. Moreover, NEC Laboratories is eagerly seeking to be exempt for commercial operations and is adversely affected by the abov e listed regu lations, in an effort to promote innovation and conceptualize new sUAS applications. (d) The petition has been filed in a timely manner. As described in more detail below, the request ed exemption would permit the operation of small, unmanned, and redu ndant sUAS’s under controlled airspace conditions that are 1) limited to the Pilot in Command’s (PIC) visual line of sight (VLOS) 2) pre

- determined and pre

- inspected 3) compliant with all government agency regulations, including but not limited to the FCC 4) would safely provide innovation and superior affordability to commercial photography/videography and emissions sensory applications.

# AIRCRAFT AND EQUIVALENT LEVEL OF SAFETY

NEC Laboratories proposes to use the following sUASs: DJI S1000 plus, DJI Ins pire, DJI Matrice M100, Harris H18 Pro and STARK H6 & Hx8 made by Harris Aerial LLC in Orlando, FL. All sUASs weigh less than 55 lbs . They will operate under normal conditions at a speed of no more than 50 knots and have the capability to hover and move in the vertical and horizo ntal planes simultaneously. The above listed sUASs are equipped with DJI A2 and/or Pixhawk (APM) Flight controllers, which are readily available on the consumer markets. Both flight controller platforms include GPS and redundant fai lsafe features, including an auto

- return function allowing the sUAS to return to the predetermined safe landing area upon loss of control, out of range deviation, and/or preconfigured low levels of power supply. Magnetic interference that can cause loss o ff GPS signal can be monitored through a mobile Ground Station application , as well as MacOS and/or Windows

- based Ground Station software equivalent. The sUASs will operate only in line of sight and will operate only within a sterile closed

- set area of a
r esidential or commercial listing or a closed

- set special event. Such opera tions will insure that the sUAS will “not create a hazard to users of the national airspace system or the public.” (Reform Act Section 333 (b)).

Given the small size of the s UASs involved and the restricted sterile environment within which they will operate, the applicant falls squarely within that zone of safety (an equivalent level of safety) in which Congress envisioned that the FAA must, by exemption, allow commercial oper ations of UASs to commence immediately. Also due to the size of the s UAS and the restricted areas in which the relevant sUASs will operate, approval of the application presents no national security issue. Given the clear direction in Section 333 of the Ref orm Act, th e 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, reduction in environmental impacts, including reduced emi ssions associated with allowing UASs for movie and television operations, the grant of the requested exemptions is in the public interest. Accordingly, the applicant respectfully requests that the FAA grant the requested exemption without delay.

Reasons w hy the exemption would not adversely affect safety, or how the exemption would provide a level of safety at least equal to the existing rule; This exemption application is expressly submitted to fulfill Congress’ goal in passing Section 333 (a) thro ugh (c) of the Reform Act. This law directs the Secretary of Transportation to consider whether certain unmanned aircraft systems may operate safely in the national airspace system (NAS) before completion of the rule making required under Section 332 of th e Reform Act. In making this determination, the Secretary is required to determine which types of UASs do not create a hazard to users of the NAS or the public or pose a threat to national security in light of the following:

 

# The UAS’s size, weight, speed and operational capability;

 

# Operation of the UAS in close proximity to airports and populated areas; an d

 

# Operation of the UAS within visual line of sight of the operator.

# If the Secretary determines that such vehicles “may operate safely in the nat ional

airspace system, the Secretary shall establish requirements for the safe operation of such aircraft in the national airspace system.” Id. §333(c). 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 exe mption 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). Hence, NEC Laboratories respectfully request your approval of the petition.



# OPERATING CONDITIONS AND LIMITATIONS NEC Laboratories proposes that the exemption requested herein apply to civil aircraft that have the charac teristics and that operate with the limitations listed herein. These limitations provide for at least an equivalent or even higher level of safety to operations under the current regulatory structure because the proposed operations represent a safety enha ncement to the already safe aerial photography and cinematography filming operations conducted with conventional aircraft.

 

# The sUAS will weigh no more than 55lbs.

 

# Flights will be operated within line of sight of a pilot and/or observer.

 

# Maximum total flight time for each operational flight will be 50 minutes or less.

 

# Each mission will consist of a crew of at least 2: one PIC and one observer. Imaging and aerial data collection personnel will be present when necessary to operate the standalone, non

- UAV operati ng equipment.

 

# The PIC will have a minimum of 50 logged flights and 50 total hours of flight experience.

 

# Observer and PIC will at all times be able to communicate by voice and/or two way radio communication system.

 

# sUAS Pilot will also meet the flig ht review requirements specified in 14 C.F.R 61.56 in an aircraft in which the Pilot is rated on his or her pilot certificate.

 

# We will operate our sUAS within the 400

- foot AGL permissible ceiling set by the FAA Moderni zation and Reform Act of 2012 (not more than 200 feet above an elevated platform for which aerial imaging and/or data collection efforts are planned) ;

 

# We will pilot our sUAS through remote control only by visual line of sight, keeping the sUAS within 500 feet of the operator at all times , until further increases in flight distance have been approved by the FAA;

 

# We will not operate the sUAS in Class A , B, C, or D airspace without written approval from the FAA;

 

# We will not operate within 4 nautical miles of the geographic center of a non

t owered airport as denoted on a current FAA

- published aeronautical chart unless a letter of agreement with that airport’s management is obtained, and the operation is conducted in accordance with a NOTAM as required by the operator’s COA.

# The letter of agre ement with the airport management will be made available to the Administrator upon request;

 

# The sUAS will only operate within a confined closed

- set area with a set safety perimeter, the boundaries of which will be determined by sUAS service personnel and the sUA S PIC based on the site

- specific activities and speed of the sUAS required for the opera tion, and coordinated with the jurisdictional FAA FSDO and local government officials as applicable.

 

# If the sUAS loses communications or loses its GPS signal, the sUAS will have the capability to return to a pre

- determined location within the Security Perim eter and land safely.

 

# During operation of the sUAS, signs will be posted warning the public that: “Caution: Small Unmanned Aircraft Operation in Progress”; or equivalent ;

 

# Our sUAS has GPS

- controlled Failsafe , a flight safety feature whereby it gai ns altitude and hovers before slowly returning to home to land. The aircraft also will enter this failsafe procedure if the signal between the PIC’s Tx and the Rx on the aircraft is lost, or manually engaged by the operator.

 

# The OSD (on

- screen displa y) device on

- board the aircraft actively records and analyzes flight data and other sources of information and streams it to the PIC’s first

- person view monitor, thus enhancing overall safety;

 

# Before each flight we will assess the environment and w il l only proceed to operate in reasonably safe conditions that are controlled and are away from power lines, airports and populated areas;

 

# We conduct extensive pre

- flight inspections and follow strict operating protocol s , during which saf

ety carries pr imary importance. A briefing will be conducted in regards 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 prese nt for this briefing.

 

# We will always obtain all necessary permissions prior to operation. If applicable, all required permissions and permits will be obtained from territorial, state, county or city jurisdictions, including local law enforcements, fire, or other appropriate governmental agencies.

 

# We will put forth our best effort to cooperate with regulatory bodies and will eagerly contribute to future improvements and development in s UAS and commercial s UAS infrastructure.

A)

. 14 C.F.R. 21 and 1 4 C.F.R. 91: Airworthiness Certificates, Manuals and the Like. 14 C.F.R. 21, Subpart H, entitled Airworthiness Certificates, sets forth requirements for procurement of necessary airworthiness certificates in relation to FAR § 91.203(a)(1).

Given t he size and limited operating area associated with the aircraft to be utilized by the Applicant, 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 Aviati on 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, maneuverability and

# proxim ity to airports and densely populated areas . In all cases, an analysis of these

criteria demonstrates that the UAS operated without an airworthiness certificate, in the restricted environment and under the conditions proposed will be at least as safe, or sa fer, than a conventional aircraft (fixed wing or rotorcraft) operating with an airworthiness certificate without the restrictions and conditions proposed. NEC Laboratories ’ sUAS permits exemption from Part 21 because our sUAS meet(s) (and exceed(s)) an equiv alent level of safety pursuant to Section 333 of the Reform Act. B). 14 C.F.R. 91.7(a) Civil Aircraft Airworthiness This section requires that no person may operate a civil aircraft without an airworthiness certificate. As no such certificate will be appli cable in the form contemplated by the FARs, this Regulation is inapplicable. Equivalent level of safety: NEC LAboratories will keep the s UAS maintenance and safety information at the ground station, where it will be readily accessible to the PIC and VO b efore, during, and after operations. The PIC will be able to reference this material when making the determination reg arding airworthiness of the specified sUAS . This exemption provides an equivalent level of safety as 14 C.F.R. 91.7(a) because the PIC wil l be able to make the determination of whether the sUAS is in an airworthy mechanical and electrical condition, in accordance with 14 C.F.R. 91.7(b). C). 14 C.F.R. § 91.9 (b) (2) , § 91.9 (c): Civil Aircraft flight manual, marking, and placard requirements.

The FAA previously stated that exemption to this section was not necessary. NEC Laboratories requests the same determination to be made for this Petition. Alternatively, NEC Laboratories requests an exemption from 14 C.F.R. 91.9(b)(2). This part provid es: "(b) 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." First, there does not currently exist a method of approving manuals for sUAS. Second, given the size and configuration of the sUAS, there is no space to carry s uch a flight manual on the aircraft. In addition, carrying the manual on the aircraft would be pointless, since there is no pilot or other person on board who could read or use it. On August 8, 2014, the FAA issued a memorandum entitled “Interpretation re garding whether certain required documents may be kept at an unmanned aircraft’s control station.” This document stated that in the case of sAUS, “maintaining these documents at the pilot’s control station would meet the intent of the rule as the pilot wou ld be able to produce the documents for his or her own information or to an FAA inspector. ” This section requires an aircraft flight manual in the aircraft. As there are no on board pilots or

# passengers, and given the size of the sUAS , this r egulation is i napplicable. An equivalent

level of safety will be achieved by maintaining a safety/flight manual delineating areas of where safety can be defined. The FAA has previously issued exemptions to this regulation in Exemption Nos. 8607, 8737, 8738, 9299, 9299A, 9565, 9565B, 10167, 10167A, 10602, 10700 and 32827. Equivalent level of safety: NEC Laboratories will keep its flight manual at the ground station, where both the PIC and VO can access it. An equivalent level of safety to 14 C.F.R. 91.9(b)(2) is provided because the intent of this rule

– the pilot having access to this material during flight

– is met. D). 14 C.F.R. 91.109: Flight instruction; simulated instrument flight and certain flight tests. The FAA has previously stated that relief from this sectio n was unnecessary when there are no training scenarios in which a dual set of controls would be utilized or required. NEC Laboratories requests the same determination to be made here. Alternatively, NEC Laboratories requests an exemption from 14 C.F.R. 9 1.109. Section 14 C.F.R. 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. Remotely piloted aircraft, including the DJI S1000 , Harris H18 Pro, STARK H6 , are designed and constructed without dual controls. Flight control will be accomplished through the use of a control box that communicates with the aircraft via a radio transmitter. Equivalent level of safety: The re quested exemption from 14 C.F.R. 91.109 will provide an equivalent level of safety to this section because NEC Laboratories’ training will not require dual controls. Rather, training will be conducted under direct supervision of an experienced and qualifie d PIC. Additionally, the DJI S1000 is a small sUAS and will carry neither a pilot nor passengers.

E). 14 C.F.R. 91.113(b): Right

- of

- way rules: Except water operations.

NEC La boratories requests an exemption from 14 C.F.R. 113(b) to the extent that it applies to overhead aircraft operating at or above 500 feet AGL as the sUAS will b e operating no higher than 400 feet AGL. This part provides: “(b): General. When weather conditions permit, regardless of whether an operation is conducted under instrum ent flight rules or visual flight rules, vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft. When a rule of this section gives another aircraft the right

- of

- way, the pilot shall give way to that aircraf

t and may not pass over, under, or ahead of it unless well clear." For example, if another aircraft is operating overhead at 10,000 feet AGL there is no danger posed to that other aircraft if the sUAS is operating under it or ahead of it at or beneath 40 0 feet AGL. Despite this, should another aircraft enter the area in which NEC

# L a boratories is operati ng , because the flight will be within the PIC’s line of sight, the PIC

will be able to give right of way to that aircraft. Equivalent level of safety: NE C Laboratories will operate its sUAS to see and avoid and give way to other aircraft that might enter nearby airspace at or below 400 feet AGL, and will give right

- of

- way to manned aircraft. Additionally, inspections of power lines and transmission towers will not interfere with manned flight, because they are pre

- existing structures that pilots will not be flying near. F). 14 C.F.R. § 91.121 Altimeter Settings This regulation requires each person operating an aircraft to maintain cruising altitude by r eference 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 global position system altitude read out with a barometric sensor, an exemption may be needed. An equivalent level of safety will be achieved by the operator, pursuant to the Pre Flight Check list, confirming the altitude of the launch site shown on the GPS altitude indicator before flight. A ltitude in formation will be provided to the pilot via a digitally encoded telemetric datalink to a real

- time display. G). 14 C.F.R. § 91.203 (a) and (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 paragr aph (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 onboar d pilot. As such, there is no ability or place to carry certification and registration documents or to display them on the sUAS.

E quivalent level of safety will be achieved by keeping these documents at the ground control point where the pilot flying the sU AS 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. We respectfully request exemption from these section for the same reasons described above. The equivalent level of safety will be achieved by maintaining any such required certifications and registrations by NEC Laboratories

. H )

. 14 C.F.R. § 45.11, 45.23, and 45.27 : Marking of the Aircraft.

# Applicable Codes of Federal Regulation require aircraft to be marked according to certain

specifications :

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 mo re than 6 inches high, the words "limited," "restricted," "light

- sport," "experimental," or "provisional," as applicable.

The sUASs we intend to use are, by definition, unmann ed. Even though the sUAS will have no airworthiness certificate, an exemption may be needed as the sUAS we intend to use do not have entrance to the cabin, cockpit or pilot station on which to mark certain words or phrases. Further, two

- inch lettering is difficult to place on such small aircraft with dimensions smaller that minimal let tering requirement. NEC Laboratories will mark the sUAS in the largest possible lettering by placing the word “EXPERIMENTAL” on its fuselage as required by 14 C.F.R. §45.29 (f) so that the PIC, or anyone assisting the PIC as a spotter will see the markings . The FAA has previously issued exemptions to this regulation through Exemptions Nos. 8738, 10167, 10167A and 10700.

I )

. 14 C.F.R. § 61.113: Private Pilot Privileges and Limitations: PIC. Pursuant to 14 C.F.R. §§ 61.113 (a) & (b), private pilots are limit ed to non

- commercial operations.

NEC Laboratories can achieve an equivalent level of safety as achieved by current Regulations. The PIC will have a current Medical and will meet the flight review requirements specified in 14 CFR § 61.56.

J )

. 14 C.F.R. § 91.119 (b) and (c): Minimum safe altitudes: General

NEC Laboratories requests an exemption from 14 C.F.R. 91.119 subpart (b) and (c). This regulation provides: "Except when necessary for takeoff or landing, no person may operate an aircraft be low the following altitudes... (b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of th e aircraft. (c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or struc ture.”

NEC Laboratories will not operate the sUAS any higher tha n 400 feet AGL. Furthermore, NEC Laboratories will necessarily operate its sUAS closer than 500 feet to the pre

existing structures and infrastructure elements for aerial data collection

. Fu rthermore, NEC Laboratories will follow the principals set forth in Part 6 of the Manual on Uniform Traffic Control Devices (MUTCD), created by the U.S. Department of Transportation’s

# Federal Highway Administration to ensure safety when it will necessarily be flying closer

than 500 feet to traffic. Equivalent level of safety : NEC Laboratories will operate the sUAS no higher than 400 feet AGL. Our sUAS operations will provide at least an equivalent level of safety to manned aircraft that are maintaining a d istance of at least "500 feet to any person, vessel, vehicle, or structure.” The 400 feet AGL maximum will provide an equivalent level of safety to 14 C.F.R. 91.119(c) because, since 1981 with AC 91

- 57, this height has been an operating standard for model aircraft.

K )

. 14 CFR § 91.151(a) : Fuel Requirements 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 cr uising 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.” The battery powering the sUAS provides approximately 20

- 40 minutes of powered flight, depending on the application . To meet the 30 minute reserve requirement in 14 CFR §91.151, sUAS flights would be limited to approximately 10 minutes in length. Given the limitations on the UAS’s proposed flight area and the location of its proposed operations within a predetermined are a, a longer time frame for flight in daylight or night VFR conditions is reasonable. NEC Laboratories 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 where only people and property owners or official representatives who have signed waivers will be allowed, with less than 30 minutes of reserve fuel, does not engender the type of risks that Section 91.151(a) was intended to alleviate given the size and speed of the small UAS. Additionally, limiting sUAS flights to 10 minutes would greatly reduce the utility for which the exemption will be granted.

We be lieve that an equivalent level of safety can be achieved by limiting flights to 30 minutes or 25% of battery power whichever happens first. This restriction would be more than adequate to return the sUAS to its planned landing zone from anywhere in its limit ed operating area. The FAA has previously issued exemptions for manned aircraft to operate at less than the minimums prescribed in 14 CFR § 91.151(a), including Exemption Nos. 2689, 5745, and 10650. In addition, similar UAS

- specific relief has been granted in Exemption Nos. 8811, 10808, and 10673 for daytime, Visual Flight Rules (VFR) conditions.

. 14 C.F.R. 91.405 (a); 407 (a) (1); 409 (a) (2); 417(a) & (b): Maintenance Inspections.

The above

- cited r egulations require, amongst other things, all aircraft owners and

# oper ators to have “ [the] 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 i n part 43 of thi s 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 airworthines s certificate, these sections will not apply to the applicant. Maintenance will be accomplished by the operator pursuant to the flight manual and operating handbook. An equivalent level of safety will be achieved because these small UASs are very limited in size and will carry a small payload and operate only in restricted areas for limited periods of time. If mechanical issues arise the UAS can land immediately and will be operating from no higher than 400 feet AGL. The operator will ensure that the UAS 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 t o provide the equivalent level of safety. Equivalent level of safety: NEC Laboratories will utilize safety protocols and the implementation of a flight operations manual that exceeds currently accepted means and methods for safe flight. NEC Laboratories will conduct formal collection of information of its operation of the sUAS, which will be shared with the FAA, and will contribute to the enhancement of the FAA's internal efforts to establish protocols for complying with the FAA Modernization and Reform A ct of 2012. NEC Laboratories ’ operation of the sUAS, weighing less than 55 pounds and traveling at low speeds within limited controlled areas will provide an equivalent level of safety as that achieved under current FARs.

To further comply with this regulation, the PIC, before each missio n, will check the
m anufacturers’ internet service pages, and ensure applicable software and hardware is up to date, and ensure compliance with any safety bulletins posted. In addition, the Operator ’ s Manual as provid ed by the sUAS manufacturer will be revised to include specific operating procedures and limitations to comply with the exemptions sought as described (see appendix A). The revised Operator ’ s Manual will be in possession of the crew during operation of the sUAS, and must be made available to the Administrator or any law enforcement official upon request. Accordingly, NEC Laboratories respectfully requests that the FAA grant our exemption request. M). 14 C.F.R. 91.215 ATC Transponder and Altitude Reporting Equipment and Use This section requires that installed Air Traffic Control (ATC) transponder equipment must meet specific performance and environmental requirements, and aircraft must be equipped with an operable coded radar beacon transponder.

Ther e are presently no known commercially available ATC transponders that meet the payload requirements of a sUAS and are available at reasonable cost. However, because the sUASs used by NEC Laboratories will not be flying into or near airports, and will fly
n o higher than 400 feet AGL, there is very low risk of collision with any manned aircraft. In addition, because there will be no need to have contemporaneous communication with ATC Control, due to the short distances, short flight times, and restricted alti tude the sUASs will operate within, NEC Laboratories requests an exemption from this section. Additionally, the sUAS is too small to contain ATC transponder equipment in any form

# that is known to be available commercially.

Equivalent level of safety: An equivalent level of safety to 14 C.F.R. 91.215 will be met because NEC Laboratories will not fly its sUAS into or near airports, and all operations will be below 400 feet AGL, so there is very low risk of collision with any manned aircraft. NEC Laboratori es will contact local ATC before operations to issue a NOTAM, and the local FSDO with its flight plan, as described previously in this petition. NEC Laboratories also will give right of way to any manned aircraft that do appear.

********* 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: Applicant seeks an exemption from the follo wing rules: 14 C.F.R. §21, subpart H; 14 C.F.R 45.23(b); 14 C.F.R. §§ 61.113(a) & (b); 91.7 (a); 91.9 (b) (2); 91.103(b); 91.109; 91.119; 91.121; 91.151(a); 91.203(a) and (b); 91.405 (a); 91.407 (a) (1); 91.409 (a) (2); 91.409 (a) (2) and 91.417 (a) & (b) to operate commercially a small unmanned vehicle (55lbs or less) in aerial photography and cinematography for residential and commercial real estate, closed

set special events and client demostrations. Approval of exemptions allowing commercial op erations of sUASs for aerial data collection and mobile aerial public announcement system testing will enhance safety by reducing risk. Conventional aerial imaging and data collection use jet or piston powered aircraft which carry large amounts of combust ible fuel and are extremely loud at lower altitudes, posing numerous environmental and health increased risk. Conversely, sUASs carry no combustibles fuel, weigh only 55 lbs. or less comparatively to 3,000+ lbs. of a conventional aircraft, are much more e asily maneuverable and do not ferry to and from the production location. Additionally, flying at or below 400 AGL sUAS will be no factor with fixed wing and rotor wing aircraft. The operation of small UASs, weighting less than 55 lbs., conducted in the strict conditions outlined above, will provide an equivalent level of safety supporting the grant of the exemptions requested herein, including exempting the applicant from the requirements of Part 21 and allowing commercial operations. These lightw eight aircraft operate at slow speeds, close to the ground, and in a sterile environment and, as a result, are far safer than conventional operations conducted with traditional aircraft which pose a safety risk. There are no personnel on board the sUASs a nd therefore the likelihood of death or serious bodily injury is significantly diminished. All flights will occur over private or controlled access property with the prior consent and knowledge, unless in
non

- restricted public areas. NEC Laboratories will p rovide an equivalent or better level of safety as that achieved under the current FAR’s.

NEC Laboratories respectfully request that the FAA grants the exemption request. 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 and national security

– provide more than adequate justification for the grant of the requested exemptions allowing commercial operation of applicant’s UAS in aerial photography and cinematography for the real estate industry and close

- set special events pursuant to the Manuals appended hereto.

## 1.3 Compass Calibration

The Compass can assistant the GPS to position the aircraft, which is very i mportant 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 i s recommended to calibrate the compass outdoor s after the C ontroller U nit finds 7 or more GPS satellites

. Regular calibration enables the compass to keep optimal performance

. 

### Calibration Caution s (1) DO NOT calibrate your compass where there is strong magne tic 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 syst em cannot work.

### Step 4 Banked Turn m o de fl ying 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) user s should select the “Use Roll” option while Mode 1 (throttle on the right stick) users

should select the “Use Yaw” option

.©201 3

Cruise C ontrol allows you to lo ck the speed of the aircraft , freeing you to control the gimbal while maintai ning 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 Cruis e Control box in the A2 Assistant to enable it.©201 3

- 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 “ S et ” or “ Continue s ”. 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 “ S et ” 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.


###  Continue s 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 retur n 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. m ode 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) M aximum speed is 15m/s under Cruise Control mode.©201 3

 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 32 0 feet (100m) of the safety zone, a warning message will appear on the DJI Ground Station

For more information on ESC calibration, battery monitoring, failsafes, mode descriptions, and more, visit ardupilot.com . Do not operate your vehicle without a complete understanding of the online instructions.Operating a powered vehicle of any kind can be a lot of fun, but it carries certain inherent risks. Regulations governing the use of powered vehicles, including aircraft, vary from locale to locale, even within the same country or district. It is your responsibility to ensure that you understand and comply with all local laws and regulations.

Safety basics:

• Never operate the vehicle or software in a way that could be dangerous to you, other people, or property.

• Always keep propeller arcs free of objects and body parts while the vehicle is live.

• Keep in mind that software and hardware failures happen. Although we design our products to minimize

such issues, you should always operate with the understanding that a failure could occur at any time and without warning. Accordingly, you should take the appropriate precautions to minimize danger in case of product failure.

• Never use the software or hardware for manned vehicles.

• Always operate within local laws and regulations.

• Do not operate the aircraft if you are under the age of 18.

Additional safety information:

• Be sure to maintain safe distances between people and your aircraft.

• Never operate your aircraft if your ability to do so with the utmost attention to safety is impaired in any

way. Do not operate your aircraft while tired, under the influence of drugs or alcohol, or otherwise unable to operate it with the highest attention to safety.

• Environment conditions can change rapidly and can make operation difficult. If this occurs, land your aircraft

and discontinue use immediately. Do not operate your aircraft if operating conditions are not ideal. This includes, but is not limited to, rain, snow or excessive wind.

• Always ensure the battery cable is disconnected from the aircraft until you are ready to fly, and ensure that

your batteries are fully charged prior to use.

• Always turn on the transmitter and ensure the throttle stick is all the way down before connecting the

battery.

• After landing, disarm your vehicle immediately and disconnect the battery cable.

• Do not turn off the transmitter until after you have disconnected the battery.

• Always remove the propellers while testing the motors.

• When the battery is connected, always assume the vehicle is live and the motors are armed.

• Do not attempt to fly longer than the battery’s safe capacity.

• Do not operate the vehicle with excess weight attached.

• Ensure that all vehicle components are well maintained before each flight. Ensure that components are

firmly attached and operating properly.

• Replace any worn or damaged components before each flight. Never operate with any damaged or worn

components.

• SAFETY IS THE FIRST PRIORITY. Take all precautions necessary to ensure your own safety as well as the

safety of other people and property.
