DearAdministrator, Sevee & Maher Engineers, Inc. (SME) is an engineering company located iri Cumberland Center, Maine. We specialize in civil, environmental, geotechnical, water, and compliance. A large portion ofourwork depends on topographic information. Current topographic surveys are performed by small planes using aerial photogrammetry, which is costly and can have lead times upto several months. Using a small-unmanned aircraft system (sUAS) SME would be able to quickly and affordably provide our clients with the topography oftheir properties. By granting this request, flights consisting ofsmall manned aircrafts would be replaced by sUAS, resulting in less airtraffic. It is also worth noting that the sUAS is powered by batteries, and would have minimal impact on the environment compared to the planes currently used for aerial surveys. The sites that SME wants to map consist ofsolid waste and industrial landfills, dams, quarries and gravel pits, and other large open areas. Most landfills are in remote areas, and operations pose nothreat to public safety. Operations are typically up to 13 minutes and follow a predetermined path to provide the photos necessaryfor photogeometric analysis. Each operation ends in the proximity ofwhere it began. A constant elevation (approximately 300 feet above ground level) is maintained. One site may require several operations. The sUAS will travel no fasterthan 10 meters per second (mps) and will never operate out of line ofsight. Granting this request will do nothing more than allow SME to dowhatthousands of hobbyists and manufacturers of model aircraft do every day, and we will abide by much stronger safety measures than currently required for these groups by FAA policies and regulations. In this petition for exemption, we seek to engage in essentially the same type ofsUAS operation that the FAAwould permit us to currently but forthe fact that SME is not a hobbyist or manufacturer ofa model aircraft.

### (c) The extent of reliefwe are seeking, and the reason we are seeking the relief We seek an exemption from several interrelated provisions of 14 C.F.R. Parts 21, 45 and 91 to the extent necessary to engage in commercial operations ofsUAS on our clients' property. We have detailed, below, a set ofsafeguards that will apply to our sUAS operations as well as a copy ofthe Aircraft Flight Manual. Our operations will not "create a hazard to users ofthe national airspace system orthe public or pose a threat to national security" and are thus consistent with the congressional mandate in Section 333 ofthe FAA Modernization and Reform Act of2012, which gives FAA a mechanism to allow certain UAS to operate safely in the national airspace system.

Z:\SME\Administration\DRONE\20141119_Drone_Petition.doc November 19, 2014 Page 2 of6

### (d) The reasons why granting our requestwould be in the public interestthat is, how itwould benefitthe public as a whole As described above, the sUAS will provide timely and affordable topographic survey. The current use of planes to perform aerial surveys has more significant impact on the environment (carbon footprint) and airtraffic. (e) The reasons why granting the exemption would not adversely affect safety, or howthe exemption would provide a level ofsafety at least equal to that provided by the rule from which we are seeking the exemption UnmannedAircraftSystem The UAS proposed is a proprietary design, conceived and constructed by Atlantic RC Aircraft, and referred to as the LC 047. This aircraft has four rotors and four motors in a quadcopter configuration (X4). Given the size, weight, speed, and limited operating area associated with the aircraft to be utilized, an exemption from 14 CFR part 21, Subpart H (Airworthiness Certificates), subject to certain conditions and limitations, is warranted and meets the requirements for an equivalent level ofsafety under 14 CFR part 11 and Section 333 ofthe FAA Modernization and Reform Act of 2012 (PL 112- 95). A UAS operated without an airworthiness certificate in the restricted environment and underthe conditions and limitations proposed by the petitionerwill be at least as safe, or safer, than a conventional aircraft (fixed wing or rotorcraft) operating with an airworthiness certificate issued under 14 CFR part 21, Subpart Hand not subjectto the proposed conditions and limitations. The unmanned aircraft (UA) to be operated underthis request is less than 55 lbs. fully loaded, flies at a speed of no more than 10 meters per second, carries neither a pilot nor passenger, carries no explosive materials or flammable liquid fuels, and operates exclusively within a secured area. In addition, there are integrated safety features into the design ofthe UAS, as described in the petitioner's Aircraft Flight Manual, to ensure the safety of persons and property within and surrounding the limited operating area. In the event the UAS loses communications or its GPS signal, the UA will have the capability to return to a pre-determined location. It will also have the capability to abort a flight in the event of unpredicted obstacles oremergencies. Even though its UAS will have no airworthiness certificate, an exemption may be needed from 14 CFR 

## § 45.23 as the UA will have no entrance to the cabin, cockpit, or pilot station on which the word "experimental" can be placed. Given the size ofthe UA, the petitioner notes that the two-inch lettering will be impossible. The petitioner asserts that an equivalent level ofsafety will be provided by having the UA marked with the word "experimental" on the fuselage in compliance with 14 CFR 

## § 45.29(f), in a Z:\SME\Administration\DRONE\20141119_Drone_Petition.doc November 19, 2014 Page 3 of6

### location where the pilot, observer, and others working with the UAwill see the identification. The maintenance requirements in the pertinent sections of 14 CFR part 91 are only applicable to aircraft with an airworthiness certificate in accordance with part 43. The UAS does not have specific maintenance instructions; therefore, there is a documented preflight and postflight maintenance process for the UAS. Any manufacturers' recommended instructions and procedures will be followed when those procedures exist for certain components ofthe UAS. 

### PilotIn Command(PIC) Since the UAwill not carry a pilot or passengers on board, the proposed operations will not adversely affect safety by requiring the PIC operating the aircraft to have no.[ghc1] pilot license. Since there are no standards for either private or commercial UAS pilot certificates, knowledge of airspace regulations and dexterity in the control and operation ofthe UAS acquired from actual operation ofthe aircraft will be the most importantfactors in establishing an equivalent level ofsafety. Furthermore, given the restricted and controlled airspace within which operations will take place, the key factors needed by the PIC are knowledge ofthe airspace within which the operation will take place and howthat airspace fits into the National Airspace System (NAS). It cannot be assumed that a commercial pilot, approved to operate a helicopter orfixed wing aircraft, has the skill or ability to safely operate an unmanned aerial vehicle, operating at 400 feetAGL or lower, within strictly controlled pre-approved airspace. Additionally, the aircraft will be operated within a secure environment, which no one will be allowed to enter unless they are part ofthe operation, have been fully briefed ofthe risks priorto operation ofthe UAS, and have consented to the risks associated with being in the operating area. Should there be a mishap, the UA being flown pose significantly less ofa threat than the helicopters and fixed wing aircraft now being employed because they are a fraction ofthe size, carry no flammable fuel, and do not carry crew or passengers. This is in stark contrast to conventional aircraft that are flown to the site, carry flammable fuel, carry passengers and crew, and operate in a much larger area. 

### UAS Operating Parameters All flights will be operated within visual line of sight (VLOS) ofa pilot and/or observer, and that the UAflights will be limited to a maximum altitude of400 feet AGL. An operatorwill ensure that only consenting personnel will be allowed within 100 feet of the UA operation. An equivalent level of safety can be achieved given the size, weight, and speed ofthe UAS, as well as the location where it is operated. The UAS will be operated within a safe operating perimeter, the boundaries ofwhich will be determined by SME personnel and only participating and consenting personnel will be allowed
Z:\SME\Administration\DRONE\20141119_Drone_Petition.doc November 19, 2014 Page 4 of6

### within this perimeter. Compared to flight operations with aircraft or rotorcraft weighing far more than its maximum 55 lb., and the lack offlammable fuel, any risk associated with the UAS operations is far less than those with conventional aircrafts. With respect to preflight actions, an exemption from 14 CFR 

## § 91.103 may be needed, because it will not have approved rotorcraft flight manuals. An equivalent level of safety will be achieved by the PIC and one additional operator taking all preflight actions as set forth in theirAircraft Flight Manual, including reviewing weather, flight battery requirements, landing and takeoff distances, and aircraft performance data before initiation offlight. Additionally, a briefing will be conducted priorto each day regarding planned UAS operations. With respect to the fuel requirements, the battery life ofthe UAS allows for a 15-minuteflight maximum. Which makes meeting the 30 minute reserve requirements in 14 CFR 

## § 91.151 not possible forthe sUAS. An equivalent level ofsafety can be achieved by limiting flights to 15 minutes or 15% of battery power, whichever occurs first. An exemption from 14 CFR 

## § 91.121 will be needed, as the UAS will have a GPS altitude read out instead ofa barometric altimeter. An equivalent level of safety will be achieved, as outlined in the Aircraft Flight Manual. Specifically, the altitude information will be provided to the UAS PIC via a digitally encoded telemetric data feed. Priorto each flight, a zero altitude initiation point will be established and confirmed for accuracy by the PIC. 

### Public Interest The petitioner states that, given the small size ofthe UA involved and the restricted sterile environment within which it will operate, and due to the size ofthe UA and the restricted areas in which the UAS will operate, approval ofthe application presents no national security issue. Given the clear direction in Section 333, the strong equivalent level ofsafety surrounding the proposed operations, and the significant public benefit, including enhanced safety, reduction in environmental impacts, and including reduced emissions associated with allowing UAS for survey operations, granting the requested exemptions is in the public interest. The attached Aircraft Flight Manual (Appendix A) includes specifics on the equipment being used.

### GPSModefor 6 to 10 times. The LED indicatorwill turn on solid BLUE. 2. Rotate your Multi-rotor around the horizontal axis (about 360°) until the LED changes to solid GREEN, and then goto the next step. 3. Hold your Multi-rotorvertically and rotate it (its nose MUST be downward) around the vertical axis (about 360°) until the LED turns off, meaning the calibration is finished.

4. The LED indicatorwill showwhetherthe calibration is successful or not.
• Ifthe LED keeps WHITE for 3 seconds, meaning the calibration is successful, and then calibration modewill exit automatically.
• If the LED keeps flashing quickly RED, the calibration has failed. Switch the control mode switch
one time to cancel the calibration, and then re-start from step 1.



### 1. You don't need to rotate your multi-rotor on a precise horizontal or vertical surface, but keep at least 45• difference between horizontal and vertical calibration. 2. If you keep having calibration failure, it might suggest that there is very strong magnetic interference around the GPS & Compass module, please avoid flying in thisarea. 3. When to do re-calibration.
• The flightfield is changed.
• The multi-rotor mechanical setup has changed, including the following situations:

a) Ifthe GPS & Compass module is re-positioned. b) Electronic devices added, removed or re-positioned (Main Controller, servos, batteries, etc). c) When the mechanical structure ofthe multi-rotor is changed.
• Ifthe flight direction appears shifting (meaning the multi-rotor doesn't "fly straight").
• The LED indicator often indicates abnormality blinking when the multi-rotor spins. But it is normal for this to happen only occasionally.
• LED blinks yellow and green**(ri>~)** continually, indicating thatthe compass data is abnormal.

# Basic Flying Test Step

# 1 Aboutthe Control Mode Switch The autopilot system can work in Manual Mode and A TTl. Mode without a GPS module. After connecting to the GPS module, GPS Mode is available. Followthe bellow stepsto enterthe different control modes. 

### l. Use a 3-position switch on the transmitteras modecontrol switch. 

### 2. Make suretotakeofftheaircraftin A TTl. Mode in everyflight. 3. Hover the Aircraft. Release all joysticks and then flip the control mode switch to the GPS Mode or Manual Mode (NOT RECOMMENDED). 

# Step2Start 

## & Stop Motor Star Motor : Pushing throttle stick before takeoff will not start motors. You have to execute any one of following four Combination Stick Commands (CSC) to startmotors

Stop Motor :The defaultsetting ofstop motoris Immediately. Forthe immediatelymode, in anycontrol mode, once motors startand throttlestick is over 10%, motorswill stop immediatelywhen throttle stickis back under 10%again. In this case, if you push the throttle stick over 10% within 5s after motors stop, motors will re-start, CSC is not needed. Ifyou don't push throttle stickaftermotors start within 3s,motorswill stop automatically. Please referto the instructions ofA1 and A2 in theAdvanced Functions section, to learn more about the Control Modeand Stop Motordetails. 

# Setp3Checking List before Flying

• Make sureyou have assembled your multi-rotor correctly. 

## e Make sureyou have donethe configuration procedure correctly. 

## e Make sure all connections are in good condition.
• Make sure batteriesarefully charged for yourtransmitter, autopilotsystem and all devices.
• Any of the following mistakes will lead to a dangerous accident, double check all these items: Rotation direction ofmotor is opposite

## I Propeller installation mistake 

## I Main controller installation mistake

## I Wrong connection between the main controllerand ESC.
• Always switch on the transmitter first, then power on multi-rotor! (Power off multi-rotor first, then switch offthetransmitterafter landing!)
• Make sure the GPS signal is good, only one Red LED blinking or without Red LED blinking.



# •

• Otherwisemulti-rotor will driftwithout stick commands. When system is powered on, you MUST NOT move your multi-rotor or sticks on transmitter until the systeminitialization is finished (about 5 second). Please AVOlD using the autopilot system in areas of urban area with crowded buildings, tunnels and under bridges, where GPS signal will be blocked most likely. In ATTI Mode, throttle stick center position is for 

### Omls along the vertical direction. You should keep the position ofthrottle stickhigherthan 10%from cut-throttle during theflight! Please dothe fly test and gaintuning with A TTl. Mode in theopen air without heavy wind!
• Refer tothe indication in the software: Basic->Gain for moredetails.

# Step4Flying Procedures 1. If in GPS Mode, placethe aircraft in an open space without buildings ortrees. Take offthe aircraft after

### 6 or
more GPS satellites are found (RED LED blinks once or no blinking). If in Manual Mode orATTl. Mode, you
can skip this step. 2. Placetheaircraftthree meters awayfrom you and others (especiallychild), toavoid accidental injury. 

## 3. Start-up

../ Switch on thetransmitter, and then power on autopilot system! You MUST NOT move your multi-rotor or stickson transmitter until the system initialization is finished (about5 second)

. ../ Push both sticksoftransmittertothe left bottom orright bottomto startthe motors
. ../ Release the yaw, roll and pitch sticks and keep them at the neutral position, avoiding the aircraftto tilt to
one side. At the same time raise the throttle stick from the bottom quickly. The motors will stop ifyou do not push thethrottle stickfrom the bottom within 3sand you will need to executethe start-up procedure again. When the aircraft is on the point ofleaving theground, continue to push the throttle stick upwards to takeofffrom the ground, pay attention nottopush the stickexcessively

. ./ Pay attention to the aircraft movement at any time when flying, and use the sticks to adjustthe aircraft's position. Keep the yaw, roll, pitch and throttle sticks at the neutral position to hover the aircraft at the desired height. 

## 4. Lowerthe aircraft slowly. Pull the throttle stickto the bottom and then push the sticks to the left bottom or right bottom to stop the motors after landing. (Also, with throttle stick under 

### 10%, and after landing 3s the motorswill stopautomatically) 

## 5. Poweroffthe autopilot system, and then switch offthe transmitterafter landing.



# 0 • DO NOT fly near to any ferromagnetic substances, to avoid strong magnetic interference with the GPS. Otherwise, it may causetheaircraftto FailSafe, crackorevenfly away. 

# • If abnormal compass data occurs during flying, LED will blink Yellow and Green alternatively (**®~** ). 

### If in A TTl and Manual Mode, it is free from influence. In any other control mode, the autopilot system will enter into A 

### TTl. Mode automatically; once the compass data goes back to normal, theautopilotsystem will regainthe original control mode.


# .. • Ifthe LED flashes quickly YELLOWthen this indicatesbatteryvoltage is low, land ASAP

. 

# • It is recommended to land the aircraftslowly, to preventthe aircraftfrom damage

. 

# • Ifthetransmitter indicates low-battery alarm, please land ASAP. In this condition thetransmitter may causethe aircraftto go outofcontrol or even crash. 

# • The LED will blink White to indicate huge cumulative yaw errors caused by spinning the craft continuously. In this case, you can stop or slow down the spinning, and continue flying after the White blinking has stopped, soasto have betterflight performance. 

# ·'f· • If Low-Voltage Alarm is set, the aircraft will act according to the configuration of the Assistant Software once Low-Voltage Alarm is triggered. 

# • If Fail-Safe function is set, the aircraft will act according to the configuration of the Assistant Software once Fail-Safe is triggered.
