# Re: Exemption Request under Section 333 ofthe FAA Reform Act and Part 11 ofthe Federal Aviation Reg,Ilations 

# Dear Siror Madam: Pursuant to Section 333 ofthe FAA Modernization and RefonnAct of2012 and the requirements contained within 14 C.F.R. Pmi 11, Aerial Precision Surveyrequests an exemption from Federal Aviation Regulations (FARs) detailed belowfor the 3D Robotics Inc. (3DR) AeroM and X8+ unmanned aircraft system. The requested exemptionwould support an application for a commercial Certificate of Authorizationto support agriculture and land mm1agement. The 3DRAero-M and X8+ systems consists ofa lightweight battery operated aircraft both weighing less than 7 pounds each, ground based PC and handheld controller, and associated communications and imaging equipment. A geo-referenced still camerais carriedbythe aircraftthat allows itto conduct precision photogrammetry and crop scouting at resolutions necessary for precision agriculture and land management. The high-resolution data will provide farmers with detailed infonnation oftheir crops allowing themto determine which m·eas may need more seeding, fertilizer, and water at a faster rate than current conventional methods. Having the data at a faster rate will help fanners maximize crop yields which will directly benefitthe agricultural industry. The unn1anned aircraft will be operated in the field withboth a Pilot in Command (PIC) and a ground-based Visual Observer (VO) in accordance withthe FAA PolicyN 8900.227 Section 14 "Operational Requirements for UAS" withthe following additional operating restrictions: 1. All operations will occur in Class G airspace at no more than 400ftAGL 2. Operations will be operated overprivate prope1iy withthe pennission ofthe land owner 3. All required permits will be obtained from state and local governn1entpriorto operation 4. The aircraft will notbe operated overurban orpopulated areas 5. The aircraft will notbe operated within 5NM ofan airport orheliport 6. The aircraft will notbe operated at air shows or over an open-air assembly ofpeople 7. The aircraft will notbe operated overheavily traffickedroads 8. Operations will belimitedto day and visual meteorological conditions Page 1

# 9. Aircraft will remain within visual line ofsight at no greaterthan 

# YzNM ofthe PIC at all times 10. While the aircraft is airborne, the VO will be positioned within voice distance to the PIC 11. PIC will file aNOT AMprovidingradial/DME, radius, and a date/time group for each operation The PIC and VO will meetthe requirements outlined inthe FAA PolicyN 8900.227 Section16 Personnel Qualifications. The PIC and VO will perform maintenance onthe system along with completing an in-service on maintenance and safety procedures as part oftheir initial training. We do not anticipate the need for a supplemental pilot, due to the simplicity ofthe system. We submitthatthe combination ofstrict operation underthe guidelines established in 8900.227 and the aircraft's light weight, historically demonstrated flight perfonnance, and a fully qualified flight crew, the FAA can have confidencethat the operation will have an equivalent or greater level ofsafety ofa manned aircraft performingthe same mission.

# EXEMPTIONREQUESTS AND EQUIVALENT LEVEL OF SAFETY 

# Aerial Precision Surveyrequests an exemptionfrom the following regulations as well as any additional regulations that maytechnically apply to the operation ofthe 3D Robotics Inc. (3DR) Aero-M and X8+ 14 CFRPart21, SubpartH: Airworthiness Certificates 

# This partestablishes the procedures for the issuance ofan airworthiness cetiificate. Whilethe FAA continues to workto develop airworthiness standards for UAS, we request an experimental certificate be issued for the 3DRAero-M and X8+under either orboth ofthe following prOVlSlOnS: 21.191 Experimental certificates Experimental certificates are issued for the following purposes: (a) 

# Research anddevelopment. Testing new aircraft design concepts, newaircraft equipment, new aircraft installations, newaircraft operating teclmiques, or newuses for aircraft. (b) 

# Showingcompliance with regulations. Conducting flight tests and other operations to show compliance with the airworthiness regulations including flights to show compliance for issuance oftype and supplemental type certificates, flights to substantiate major design changes, and flights to show compliance with the function andreliability requirements ofthe regulations. Since the experimental cetiificate canbe used for commercialpurposes such as market surveys, sales demonstrations, and customer crewtraining, we would expectthat an experimental certificate wouldpermitfor our commercial purpose as well. The aircraft will not canypersons orpropetiy, will not canyfuel, and will only fly under strict operationrequirements. Combined withthe fact that the Aero-M weighs only 6.8 pounds and is constructed primarily out offoam, and the X8+ weighs 5.6 pounds and is composed primarily of aluminum and carbon fiber, we propose that the 3DRAero-M and X8+ will be at least as safe, if not safer, than a conventionally certificated aircraftperformingthe same mission. Ifan experimental airworthiness ce1iificate is not appropriate for this application, then we request an exemption of 14 CFRPmi 21, Subpart H, andthe requirement for an airwmihiness cetiificate in general, citing the equivalent level ofsafety outlined inthe previous paragraph. 14 CFR91.203(a) & 

# (b) Civil aircraft: Certifications required. 

# The regulationprovides that an airworthiness certificate, withthe registrationnumber assigned to the aircraft and a registration certificate must be aboard the aircraft. Additionally, subparagraph (b) provides that the airworthiness certificate be "displayed at the cabin or cockpit entrance so that it is legible to passengers or crew." At 6.8 m1d 5.6 pounds the 3DRAero-M and X8+ are too small to carry documentation, they do nothave an entrance, and are not capable ofcarrying passengers or a crew. Page

## AppendixA


# To obtain an equivalent level ofsafety and meetthe intent of91.203, we propose that documents deemed appropriate for this aircraft by the FAA will be located withthe crew at the ground control station and available for inspection upon request. In orderto identify the aircraft, we propose that the following informationbe pennanently affixedto the aircraft viaplacard: Manufacturer: 3D Robotics Inc. Model: Aero-M orX8+ Serial Number: Registered to: Aerial Precision Survey

10662 W First Court Star, ID 83669 Iffound please contact: (208) 353-4402 14 CFR45.23 Display ofmarks; general and 45.29 Size ofmarks. 

# These regulations provide that each aircraft must display "N"and the aircraft's registration number in letters at least 3 inches high. Additionally, the aircraft must display the word "EXPERIMENTAL" inletters at least 2 incheshighnearthe entranceto the cabin, cockpit, or pilot station. The 6.8 and 5.6 pound 3DRAero-M and X8+ do not have an entrance in whichthe word "EXPERIMENTAL" canbe placed, and may not have a registration number assigned to it by the FAA. We propose to achieve an equivalentlevel ofsafety by including the word "EXPERIMENTAL" on the top ofthe aircraft, where the PIC, VO and others inthe vicinity ofthe aircraft while itis preparing for launch will be able to see the designation. We feel thatthe permanentplacard discussed inthe previous paragraphwill provide the aircraft's registration infonnation should it be found on the ground. We will also display at the ground station a high contrastflag orbanner that contains the words "UnmannedAircraft Ground Station" in letters 3 inches high or greater. Since the aircraft will operate within 

# Yz NM ofthe ground station, the ba1111er shouldbe visible to anyone that observes the aircraft and chooses to investigate its point oforigin. 14 CFR91.9 Civil aircraft flight manual, marking, and placard requirements. 

# This regulation provides that no person may operate an aircraft unless a current, approved flight manual is in the aircraft. We assume that the intent ofthis requirementis to ensure that flight manual information is available to the aircrew while operatingthe aircraft. We request an exemptionto this requirement since the aircraft is not only too small to cany documentation, the documentation would notbe available to the crew. To obtain an equivalent level ofsafety and meetthe intent of91.9, weproposethat a current approved Airplane Flight User Manual (appendix G) must be available to the flight crew atthe ground station anytime the aircraft in in or operating for flight.

# 14 CFR61.113 Private pilot privileges and limitations: Pilot in Command and 61.133 Commercial pilot privileges and limitations. 

# Section 61.113(a) states that "nopersonwho holds aprivatepilot certificate may act as a pilot in command ofan aircraft that is canyingpassengers orproperty for compensation orhire; nor may thatperson, for compensation orhire, act as pilot in command ofan aircraft." Section 61.113(b) states that "Aprivate pilot may, for compensation orhire, act as pilotin conm1and ofan aircraft in connectionwith any business or employment if: (1) The flight is only incidental to thatbusiness or employment; and (2) The aircraft does not carrypassengers or property for compensation orhire." Section 61.133(a) states that "(1) 

# General. A person who holds a co111111ercial pilot certificate may act as pilotincommand ofan aircraft
- (i) Canyingpersons orproperty for compensation orhire, providedthe person is qualified in accordance with this part and withthe applicable parts ofthis chapterthat apply to the operation; and (ii) For compensation orhire, provided the person is qualified in accordance withthis part and withthe applicable parts ofthis chapter that apply to the operation." We request exemption from sections 61.113(a) and (b), and section 61.133(a) because our proposed operations include commercial operations. Considering the size, weight and operating characteristics of3DRAero-M and X8+ in question, and considering thatthe operation ofthe UAS is to be confinedto an area overprivate prope1iy with controlled access, Aerial Precision Survey requests an exemption from section 61.113(a) and (b) withthe following conditions: 1. The Pilot in Command (PIC) ofthe UAS must hold at least a private pilot airman certificate and a third-class ainnanmedical certificate and: 2. UAS operation will additionally require a Visual Observer (VO) and the VO musthave acceptable vision suchthatthey canmaintain visual line ofsight (VLOS) with the UAS at all times Additionally, boththe 3DRAero-M and X8+ are equipped with an onboard autopilot for autonomous flight, capable ofbeing (and required bythe operating manual to be) monitored by a Ground Control Station (GCS) at all times. The onboard autopilot will also ensure flight operationis kept withinthe controlled airspace, includingprohibiting operation above a defined maximum altitude. 14 CFR91.109 Flight instruction; Simulated instrument flight and certain flight tests 

# The regulationprovides that "No personmay operate a civil aircraft thatis being used for flight instruction unless that aircraft has fully functioning dual controls." The 3DRAero-M and X8+ ground control stations are based on a ground based PC andhand-held controllerthat offers a trainer plug for a second set of"controls", boththe student and instructor can, and will, operate the controls simultaneously. Withboth student and instructor having "hands-on" the controls during flight, we feel thatthis meets the intent of91.109 and provides an equivalentlevel of safety. Page 6

## AppendixA 

# 14 CFR91.119 Minimum safe altitudes: General The regulationprovides that over sparselypopulated areas the aircraft cannotbe operated closer than 500 feet to anyperson, vessel, vehicle, or structure. Sincethe aircraft will be operating at a maximum of400 feet AGL, we cannot comply withthis requirement. To provide an equivalent level ofsafety we will only fly overprivate property withthe permission ofthe land owner. The land owner willbe briefed ofthe expectedroute offlight and the associatedrisks to persons and property onthe ground. We maintain that due to the small size ofthe 3DRAero-M and X8+, the hazard to persons, vessels, vehicles, and structures is not comparableto manned aircraft and should be consideredin granting the exemption. The aircraft will not be operated over congested areas nor over any open air assembly ofpersons. The aircraft will be operated at an altitude allowing, ifapowerunit fails, an emergency landing withoutundue hazardto persons orprope1iy onthe surface. 

# 14 CFR91.121 Altimeter settings The regulationprovides that aircraft shall maintain cruising altitudes by reference to an altimeter setting available within 100 nautical miles ofthe aircraft. The aircraft will fly below400 feet AGL and will notneed to maintain hemispherical cruising altitudes in order to de-conflict with other aircraft. An appropriate altimetermeasurement presentedto the pilot should be above ground level and should be based onthe barometricpressure at thepoint oflaunch. To provide an equivalent level ofsafety, the UAS's AGL altimeter will be setto zero onthe ground priorto every flight. Since neither aircraft will t1y more than 40 minutes, evenrapid changes in barometricpressure will have limited e±Iect onthe safety ofthe t1ight. 

# 14 CFR91.151 Fuel requirements for flight in VFRconditions The regulationprovides that no personmaybegin a flight in an airplane under day-VFR conditions unless there is enough fuel to fly to the first pointofintended landing and to fly after that for at least 30 minutes. We feel thatthe intention ofthisparagraph is to provide a reserve of energy as a safety butler for go-arounds and other delays to landing. The 3DRAero-M and X8+ are battery operated and the maximum duration offlight from a single battery charge is 40 minutes for the Aero-M and 15 minutes for the X8+. Since the aircraft will never fly more than 

# Yz NMfrom thepoint ofintended landing, a full battery charge atlaunch will ensure that we meetthe reserve energyrequirement ofthis paragraph. Werequest an exemptionto the word "fuel" and ask for an equivalent interpretation withthe word "energy". 

# 14 CFR Subpart E (91.401-91.417)- Maintenance, Preventive Maintenance, and Alterations The regulationprovides thatthe operator is primarilyresponsible for maintainingthe aircraft in an airworthy condition, including compliance withpart 39 and 43. Paragraphs 91.407 and 91.409 require that the aircraftbe "approved for return to service by aperson authorized tmder 43.7" Page 7of8

## AppendixA 

# after maintenance and inspection. It

# is our intentionthat the PIC perform maintenance and inspection ofthe aircrafts and "be authorized to approve the aircrafts for retumto service." As provided in the attached Maintenance Procedures (appendices D & 

# E), the PIC will ensure that the aircraft is in an airwmihy conditionprior to flight and conduct detailed inspections after every 10 hours. Maintenance will perfonned and maintained by the PIC perthe operating manual, which contains instructions and procedures for inspecting, maintaining, and repairing the UAS. The PIC will document workperformed in accordance with 91.417. We feel that due to the size, construction, and simplicity ofthe aircrafts, the PIC can ensure an equivalent level of safety. 8900.227 Paragraph 16(c) (4) PIC Medical. And Paragraph 16(e) (1) Observer Medical. This policyprovides that boththe PIC and VO musthave a valid FAA second-class medical cetiificate issued underpart 67 in orderto perform as a pilot or observer. The aircrafts weigh 6.8 and 5.6 pounds. Requiring the crewto meet the same medical requirements as a commercial pilot canyingpassengers in a large aircraft is an mmecessary burden. We propose that the minimummedical requirements be vision corrected to 20/20 and a valid, state-issued driver's license. Due to the size and weight ofthe aircraft, the greatest hazard ofour proposed operationwill be driving to the launch site. A licensed driver is medically qualified to operate amuch largervehicle. The 20/20 vision requirementwill ensure thatthe PIC and VO can see and avoid air traffic. Given the unlikely event that boththe PIC and VO become medically incapacitated while the aircraft is in flight, the 3DRAero-M and X8+ will recover autonomously to the landing location designated prior to launch without crewintervention.

## Appendix B



# Failure messages RCfailures (i.e. transmitter/receiverfailures): 

# RC not calibrated :the radio calibrationhas not beenperformed. RC3 MIN and RC3 MAX must havebeen changed from their default values (1100 and 1900) and for channels 1to 4, the MIN must be less than 1300 and the MAX greater than 1700. Barometerfailures: 

# Baro not healthy : the barometer sensor is reporting that it is unhealthy which is nonnally a sign ofa hardware failure. 

# Alt disparity :the barometer altitude disagrees withthe inertial navigation (i.e. Baro + Accelerometer) altitude estimate by more than 2 meters. This message is normally shmt-lived and can occur whenthe flight controller is first plugged in orif

# itreceives a hardjolt (i.e. dropped suddenly). Ifit does not clearthe accelerometers may needto be calibrated orthere maybe a barometerhardware issue. Compass failures: 

# Compass not healthy :the compass sensor is reporting that it is unhealthy which is a sign ofa hardware failure. 

# Compass not calibrated: the compass(es) has notbeen calibrated. the COMPASS_OFS_X, Y, Z parameters are zero or the number or type ofcompasses connected has been changed since the last compass calibration was performed. 

# Compass offsets too high :theprimary compass's offsets length (i.e. sqt1(x"2+y"'2+z"2)) are larger than 500. This can be causedbymetal objects being placedtoo close to the compass. If only an internal compass is beingused (notrecommended), it may simply be the metal inthe board that is causingthe large offsets and this may not actually be a problemin which case you may wishto disable the compass check. 

# Checkmag field: the sensed magnetic field inthe area is 35% higher or lowerthan the expected value. The expected length is 530 so it's> 874 or< 185. Magnetic field strength varies around the worldbutthese wide limits mean it's more likely the compass calibrationhas not calculated good offsets and should be repeated. 

# Compasses inconsistent :the internal and external compasses are pointing in different directions (offby >45 degrees). This is normally caused by the external compasses orientation (i.e. COMPASS_ ORIENTparameter) being set incorrectly. Page 2 of4

## Appendix B 

# GPS related failures: GPS Glitch :the GPS is glitching and the vehicle is in a flight mode thatrequires GPS (i.e. Loiter, PosHold, etc) and/orthe circular fence is enabled. 

# Need 3D Fix: the GPS does not have a 3D fix andthe vehicle is in a flight mode thatrequires the GPS and/orthe circularfence is enabled. 

# Bad Velocity: the vehicle's velocity (according to inertial navigation system) is above 50cm/s. Issues that couldlead to this include the vehicle actually moving orbeing dropped, bad accelerometer calibration, GPS updating at belowthe expected 5hz. 

# High GPS HDOP: the GPS'sHDOP value (ameasure ofthe position accuracy) is above 2.0 and the vehicle is in a flight mode that requires GPS and/orthe circular fence is enabled. This may beresolved by simply waiting a few minutes, moving to a location with a better view ofthe sky or checking sources ofGPS interference (i.e. FPV equipment) are moved further from the GPS. Alternativelythe check canbe relaxed by increasing the GPS_HDOP_GOOD parameterto 2.2 or 2.5. Worst case the pilotmay disable the fence and take-offin a modethat does not require the GPS (i.e. Stabilize, AltHold) and switch into Loiter after arming butthis is not recommended. Note: the GPS HDOP canbe readily viewed through the Mission Planner's Quicktab as shown below.

INS checks (i.e. Acclerometer and Gyro checks): 

# INS not calibrated : some or all ofthe accelerometer's offsets are zero. The accelerometers need to be calibrated. 

# Accels not healthy :one ofthe accelerometers is reporting it is not healthy which could be a hardware issue. This can also occur immediately after a firmware update before the boardhas been restarted. 

# Accels inconsistent :the accelerometers are reporting accelerations which are different by at least lm/s/s. The accelerometers need to be re-calibrated or there is a hardware issue. Page 3 of4

## Appendix 

## B 

# Gyros not healthy : one ofthe gyroscopes is reporting it is unhealthy which is likely a hardware issue. This can also occurilmnediately after a firmware update before the boardhas been restarted. Gyro cal failed :the gyro calibrationfailed to capture offsets. This is most often causedby the vehicle being moved during the gyro calibration (whenred and blue lights are flashing) inwhich case unplugging the battery andplugging it in again while being careful not tojostlethe vehicle will likelyresolve the issue. Sensors hardware failures (i.e. spikes) can also cause this failure. Gyros inconsistent :two gyroscopes are reporting vehicle rotation rates that differ bymore than 20deg/sec. This is likely a hardware failure or causedby a bad gyro calibration. Board Voltage checks: CheckBoard Voltage: the board's internal voltage is below4.3 Volts or above 5.8 Volts. Ifpoweredthrough a USB cable (i.e. while onthe bench) this can be caused by the desktop computerbeing unable to provide sufficient currentto the flight controller- try replacing the USB cable. Ifpowered from a battery this is a serious problem and thepower system (i.e. Power Module, battery, etc) should be carefully checkedbefore flying. Parameter checks: Ch7&Ch8 Opt cannot be same: Ch7 and Ch8 auxiliary switches are setto the same option which is notpermittedbecause it could leadto conu1sion. CheckFS_THR_ VALUE :theradio failsafe pwmvalue has been settoo close to the throttle channels (i.e. ch3) minimum. CheckANGLE_MAX: the ANGLE_MAXparameter which controls the vehicle's maximum lean angle has been set below 10 degrees (i.e. 1000) or above 80 degrees (i.e. 8000). ACRO_BAL_ROLL/PITCH :the ACRO _BAL_ROLL parameter is higher thanthe Stabilize Roll P and/orACRO _BAL _PITCHparameter is higherthanthe Stabilize PitchP value. This could lead to the pilotbeingunable to control the lean angle inACRO mode because the Aero Trainer stabilization would overpowerthe pilot's input.

## To create a map, the X8 flies an autonomous mission over the survey site, using the integration between the Pixhawk autopilot and custom-programmed camera to capture images at a consistent distance interval. Pix4Dmapper then stitches these images together into a georeferenced, orthorectified mosaic. The accuracy ofthe map depends on the configuration of the mission. Planning a mission that captures high-quality images requires balancing the X8's operating parameters with the environmental factors at the survey site. Operating Parameters

Mission Planner allows you to plan the mission away from the mapping location; however, it is important to assess the environmental conditions on site at the time ofthe mission and adjusttheflight plan if necessary. Alternatively, you can plan the entire mission atthe mapping location. To create or alterthe mission, Mission Planner requires an Internet connection to access the maps. If you're unable to accessthe Internet on site, follow the instructions belowto pre-fetch the maps within Mission Planner while you have Internet access.

Open Mission Planner, select

### Set Angle Wind Direction In environments with winds of less than 6 m/s, set the angle so that the X8 flies into the wind. In winds from 7-1 0 m/s, configure the flight path totravel perpendicularto the wind so the X8 flies cross-wind. No. of Strips Adjust the angle so that the X8 makes as few turns as possible to complete its course. The 

## No. ofStrips parameter shows how many passes the X8 will make as you adjust the angle. Review Wind Conditions On-Site Always assess the wind conditions at your survey site at the time ofthe mission and adjust the mission accordingly.

Angle in low winds (1-6 m/s)

Angle in high winds (7-10 m/s)

Use caution when flying in winds over 1Om/s. Mapping results may degrade as a result ofinabilityto make headway or maintain appropriate groundspeed. 

### 12The survey altitude determines the duration ofthe mission and the ground resolution ofthe final map. Adjust altitude to balanceflight time and power consumption with the current environmental conditions.

Mission Planner Surveytool



### Check Ground Resolution Ground Resolution is the centimeters per pixel that you will have in the map and corresponds to the amount of detail that you will see. To improve ground resolution by decreasing the number of centimeters per pixel, decrease altitude. Set Altitude Recommended altitude: 60 m Operating altitude: 50-1 00 m Increasing altitude decreases flight time, allowing you to cover more area per minute. Decreasing altitude improves ground resolution. Set the altitude to get the best ground resolution while keeping the flight time under 14 min and the altitude under 120 m.
Keep altitude below 120 m, and ensure that the altitude is appropriate for your flying area and local regulations.

Check Flight Time

### a fully charged X8 battery. To decrease flight time, increase altitude or speed. High winds, humidity, high altitude, and extreme heat can affect power consumption and reduce flight time. Consider the environmental factors at your site when configuring flight time. In this example, we increased speed to 8 m/s to keep flight time below 14 min while allowing for moderate wind conditions. When increasing speed, keep in mind that the increased power required to travel faster will impact flight time. 13With the basic parameters in place, verify that the photo interval calculated from the altitude and speed complies with the operating parameters forthe camera.

# Safety

To ensure safe and successful flying, familiarize yourself with the safety information on this page. Always fly in accordance with your location regulations and these best operating practices.
Before you fly, determine the boundaries ofyour safe flying area. Ifthe X8 moves outside the designated area or exhibits instability in flight, switch to altitude hold mode and land the copter manually. The X8 will not avoid obstacles on its own, including during missions. As the operator, it's yourjob to recognize and avoid obstructions while flying. Always be ready to regain manual control ofthe copter in the event of an unsafe situation.

# Failsafes
The X8 is programmed with a set offailsafe behaviors to prevent a crash in the event of a loss of one ofthe data or communication channels required for autonomous flight. Although certain failsafes have assigned LED indicators and tones, it is unlikely that you will be ableto see these at a distance. Monitorthe Flight Data screen for failsafe indications. If a failsafe is triggered, the assigned behavior will activate. To override the failsafe behavior (RTL in most cases), use the controller to regain manual control. Regaining Manual Control To regain manual control during the mission, switch to altitude hold mode using the controller. If you're a confident operator, switch to stabilize modefor full manual control. Ifyou observe instability in theXS's flight behavior or it the aircraft moves outside your designated safe flying area, switch to RTL. Turning offthe controller will automaticallytrigger an RTL and can be used in an emergency situation as a hard recall command. Ground Station Signal Failsfe Physical obstructions and interferencefrom nearby wireless signals can affect the XS's connection with the ground station.

# Concepts Understanding key concepts in aerial images can help you understand the mission planning process and create better maps. Distance-Based Imaging By default, the camera captures only the images required to create the map. The Pixhawk monitors the distance traveled by the aircraft and sends a command to the camera to capture an image at the distance interval specified by the cameratrigger distance parameter 

### (CAM_TRIGG_D/Sl). This parameter is set by the Mission Planner Survey tool during survey configuration by calculating the minimum distance between images based on the parameters specified for the survey (altitude, overlap, sidelap). This distance-based imaging allows for more precise data collection, resulting in less images and data storage cost. Once configured, the Survey tool creates an event atthe start ofthe mission script (after takeoff) to set the camera trigger distance to the specified interval and an event at the end ofthe mission (before landing) to reset the cameratrigger distance to 0. Time-Based Imaging The camera is also equipped to capture images at a consistent time interval instead of using distance. This function can be useful ifyou want to capture images over an area without planning a mission. This time-based imaging results in more images per area, and therefore more processing time and storage cost. See the Trigger Type options on page xx to enable time-based imaging. Overlap and Sidelap To capture images for the map, the aircraft flies a lawnmower-like pattern in strips across the survey site. The front-to-back overlap between sequential images is called overlap; the side overlaps ofadjacent pictures in different strips is called sidelap. The overlap and sidelap parameters in the Survey tool (see Advanced Options page xx) determine the distance between images and the number ofimages to be captured based on the projected ground area that each image will cover, called a footprint. Increasing overlap and sidelap improves the accuracy ofthe map while increasing flight time and processing time.

In the Survey tool, 

### Distance between Imagesshows the specified cameratrigger distance that will be assigned tothe mission. You can also see the projected image footprint size and the total number of images to be captured.

# ! Safety- Read Before Flying 

# ! Your first priority must absolutely be the safety of people! Multicopters are essentially Flying Lawnmowers! • ArduCopter is an experimental aircraft running community-created code- Novel and unexpected results are NOT uncommon! • Crashes can happen, because of pilot error or hardware or software malfunction. • Especially while you are learning, it is recommended that you avoid, stiff, ultra-sharp carbon fiber props. o Get cheaper moreflexible and more breakable plastic ones. o Some carbon fiber props cut better than a Ginsu and while they are almost indestructible, you are not. • If you are flying anywhere near other people, you are putting them at risk! • Be sure to maintain safe distances between yourself, and spectators and your copter. o Circumstances will require that you will need to make your own determination of what is a "safe distance" from people and property. o At a minimum, consider: at least 1Oft (3m) but not further than 30ft (1Om) from you. o Keep all other people, property and obstacles considerably further away from your copter. o 

## Ensure that no one gets between you and your copter. o 

## Spectators should always be a safe distance behind the pilot. o If people intrude beyond what you have determined to be the "safe" area, land immediately and do not take off until they are clear. o 

## At full power, an average sized multi-copter can exceed 20 mph (32 km/h), can ascend to hundreds of feet and easily travel more than a mile in distance before running out of battery. • Always ensure that the battery cable is (NOT) connected to the power distribution board or harness until you are ready to fly. o After landing the first thing you should do is disconnectyour battery cable. o Always remove your props while you are testing motors. o Your hands, arms and face and those of your friends will thank you. o When the battery is connected, always assume the motors are armed. o Check with a short throttle pulse. o Don't pick up the model and the radio at the same time, you may bump the throttle. o 

## Do not attemptto fly longer than your batteries safe capacity. • At a minimum it is very hard on the battery and at worst you will crash destructively. • The APM and PX4 flight controllers we use incorporate a motor arming safety feature. o Immediately prior to flight after the battery has been connected, the RC transmitters throttle stick needs to be held down and to the right for several seconds to arm the motors. o After landing your first response should be to hold the throttle down and to the left for several seconds to "Disarm" the motors. o 

## Disarm condition can be tested by moving the throttle stick up, if the motors do not move it is dis armed. o 

## Even when disarmed, the throttle stick should always be kept in the full down position except when flying. • Get used to switching back to Stabilize mode from other modes and reassuming full manual control. o 

## This is the single most important recovery technique (practice it). o Stabilize mode can have Simple mode added to it, but if you do, practice with it till you are proficient. o 

## Do not use any modes other than Stabilize or Stabilize plus Simple until you are VERY comfortable flying. • Important primary response to a crash, inadequate landing or unknown flight controller state. o The first thing to do is throw a towel over your copters propellers (Propellers may start spinning unexpectedly). o Then immediately disconnect the battery. o 

## A large towel is your most important piece of safety equipment followed by a fire extinguisher and a first aid kit. --Generally better to use the first one than the last one. • When testing orflying any of the navigation modes (using GPS): o Ensure that your GPS has "Lock" before arming and takeoff. o 

## Check that your home position on the Mission Planner is in fact correct. o Sometimes GPS's do not report the home position accurately, reboot if not accurate and wait for 8 or more satellites (notjust 3D lock) and check again.I 

### l 

# Keep a safe distance between your Copter and People! These tips can also help protect your multicopter from damage. • Avoid sudden or extreme transmitter control stick deflections o Move the control sticks in small measured increments and don't "yank" on them. o If the copter is properly calibrated and balanced it should require only small stick inputs to control altitude, direction and speed. o 

## Your copter should be more or less stable on the horizontal plane without any control inputs. o 

## If you are "fighting" the copter, land and fix it- something is not right- Hardware adjustment or software calibration may be required. o Be especially careful of large throttle inputs, as a copter can gain (or lose) altitude very rapidly. • Because MultiCopters are symmetrical it is especially easy to lose Visual Orientation. o For manual flight modes, maintaining a clear vision of the Copters Orientation (direction it is facing) is the most critical part of successful flight. o Especially while learning it is very important to keep your copter appropriately close to you to aid in maintaining visual orientation. o Generally: more than 1Oft (3m) but not further than 30ft (1Om) from you. o If the copter getsfurther than about 1OOft (30m) it starts getting difficult to be able to maintain orientation and can easily crash. o If you lose Yaw orientation while flying in Stabilize mode, try only flying forward and using yaw to steer like a car. o 

## It is much better to simply descend and land rather than have an orientation-induced crash or fly away. • Fly-Aways often happen when the copter is commanded to tilt back towards the pilot but has rotated in the meantime and is so far away that orientation is lost. • Result: the copter flies further away and crashes or is lost. • Always have Stabilize mode as the {Go To) one of your 3 options. • High or unexpected winds or gusts can make flight considerably more difficult. o High winds can prevent forward progress or spin the copter around causing you to become disoriented. o The higher you are, the more likely high winds will be a problem. o 

## Switching to Stabilize mode and landing before you reach your skill limits can help you save your copter. • Avoid flying at high speed or high altitude until you have gained considerable confidence in both manual and automatic modes. • When flying around trees or buildings it is very easy to lose visual orientation or even to lose sight of the copter completely. o Gusting winds around objects can also worsen the problem and radio signal loss can also occur. o If your copter is approaching a potentially interfering object, immediately switch to stabilize mode and land or retrieve the copter to your location. • ArduPilot specific safety modes: RTL, FailSafe and GeoFence. o RTL can provide a safe Return to Launch if it starts to get away from you. o FailSafe and GeoFence can assist you with keeping the copter in a safe proximity. o 

## Do not rely on the above safety modes, always be ready to take control in stabilize and land the copter. o 

## Especially do not rely on the above safety modes to perform maneuvers or training that you would otherwise consider dangerous. o These modes are a supplement to, not a replacement for sound safety practices. • On your first takeoff after tuning or hardware setup o 

## In stabilize mode advance the throttle very slowly until the copter is almost hovering. o If the copter is trying to flip over turn it off and correct the problem, a motor could be turning the wrong direction, or a wrong direction prop could be installed. o If the copter tries to rotate on it's axis or fly off in some direction the transmitter or RC setup may be incorrect, a motor or ESC may not be performing properly or the props may be installed incorrectly. o When all problems are fixed it should be fairly easy to get the copter to hover a foot or 2 above the ground. o If a stable and stationary hover a foot or 2 above the ground cannot be achieved, land and fix the problem • When flying FPV "First Person View" {with a video camera), Set modes to: STABILIZE, SIMPLE, and RTL. o Ensure RTL is working properly before using FPV, o 

## Use Stabilize mode to fly FPV and If you lose FPV video switch to Simple or RTL to get back. • Make sure your battery can't fall out, use a Velcro Strap to hold it in place.

To create a map, the Aero flies an autonomous mission over the survey site, using the integration between the Pixhawk autopilot and custom-programmed camera to capture images at a consistent distance interval. Pix4Dmapperthen stitches these images together into a georeferenced, orthorectified mosaic. The accuracy ofthe map depends on the configuration ofthe mission. Planning a mission that captures high-quality images requires balancing the Aero's operating parameters with the environmental factors at the survey site.

### 12The suNey altitude determines the duration ofthe mission and the ground resolution ofthe final map. Adjust altitude to balanceflight time and power consumption with the current environmental conditions.

Mission Planner SUJveytool

Check Ground Resolution 

### GroundResolution is the centimeters per pixel that you will have in the map and corresponds to the amount of detail that you will see. To improve ground resolution by decreasing the number of centimeters per pixel, decrease altitude. Set Altitude Standard operating altitude: 100 m Operating altitude range: 80-120 m Increasing altitude decreases flight time, allowing you to cover more area per minute. Decreasing altitude improves ground resolution. Set the altitudeto getthe best ground resolution while keeping the flight time under 40 min and the altitude under 120 m. 

# A Keep altitude below 120 m, and ensure thatthe altitude is appropriate for yourflying area and local regulations.

Check Flight Time Flight Time estimates the duration ofthe mission. The total estimated flight time must be under40 min for a fully charged Aero battery. To decrease flight time, increase altitude or speed. High winds, humidity, high altitude, and extreme heat can affect power consumption and reduce flight time. Considerthe environmental factors at your site when configuring flight time.

# Safety

To ensure safe and successful flying, familiarize yourself with the safety information on this page. Always fly in accordance with your location regulations and these best operating practices.
Before you fly, determinethe boundaries ofyour safe flying area. Ifthe Aero moves outside the designated area or exhibits instability in flight, switch to fly-by-wire mode and land the plane manually. Always be ready to regain manual control ofthe plane in the event of an unsafe situation. The Aero will not avoid obstacles on its own, including during missions. As the operator, it's yourjobto recognize and avoid obstructions while flying. When planning missions, ensure that the selected altitude is appropriate for all geographical features ofthe area, including terrain.

# AutomaticTakeoff
Auto-takeoffworks by sensing the movement ofthe plane and launching it in that direction. Set the Aero to autonomous modewhen you're ready to launch. Find a launching area with at least 100feet of clear space in front ofyou. Face into the wind, and hold the body oftheAero in one hand underthe center of gravity. Be careful notto place your hand in the way ofthe propeller! Hold the Aero above your head, run, and throwthe plane at an upwards angle. The Aero will sense thethrow, powerthe motor, and climb to the altitude specified by the takeoffwaypoint before starting the survey mission.

DO NOTWIND UP YOUR THROW; ifthe Aero senses any backwards momentum itwill attempt to launch in that direction. Use onlyforward moment\.lm to throwto Aero!

Automatic takeoff requires you to configure thetakeoff angle during mission planning. See page 18. 

# Takeoff
If you're new to planes, we recommend having a friend help you launch the Aero. Have yourfriend throw the Aero while you control the controller. We recommend setting the Aero to fly-by-wire modefor takeoff. Find a launching area with at least 100feet of clear space in front ofyou. Face into the wind, and hold the Aero at the center of gravity. Raise thethrottle to center position to start the motor. Be careful notto place your hand in the way ofthe propeller! Hold the Aero above your head, run, and throwthe plane at an upwards angle. Once launched, the Aero will require immediate adjustment with the controller to navigate away from the ground and up to the desired altitude. Pitch up (right stick down) and add any other necessary controls based on wind, speed, and terrain.

# Automatic**Landin~**
To land automatically at the end ofthe mission, the Aero requires the mission to be configured with a specific pattern of landing waypoints that gradually decreasesthe altitude so thatthe Aero can land safely. For instructions on configuring automatic landing, see page 18. 

# Manual**Landin~**
When you're ready to end yourflight, follow these steps to land: - 

## » Fly a circle pattern aboveyour landing area. 

## » Come in on a final approach, flying into the wind at an altitude of20to 40 meters. 

## » When the plane reaches an altitude of 10 meters, set thethrottle fully down to turn offthe motor and glide down on a 15to 20 degree down-pitch angle. 

# A. After stopping the motor atan altitude of 10 m, keepyourthumb onthethrottle stick in fully down position to ensure thatthe motordoes not accidentally spin during landing.

# Concepts Understanding key concepts in aerial images can help you understand the mission planning process and create better maps. Distance-Based Imaging By default, the camera captures only the images required to create the map. The Pixhawk monitors the distancetraveled bythe aircraft and sends a command to the camerato capture an image atthe distance interval specified by the cameratrigger distance parameter 

### (CAM_TRIGG_DIS7). This parameter is set by the Mission Planner Survey tool during survey configuration by calculating the minimum distance between images based on the parameters specified forthe survey (altitude, overlap, sidelap). This distance-based imaging allows for more precise data collection, resulting in less images and data storage cost. Once configured, the Survey tool creates an event at the start ofthe mission script (aftertakeoft) to set the camera trigger distance to the specified interval and an event atthe end ofthe mission (before landing) to reset the cameratrigger distanceto 0. Time-Based Imaging The camera is also equipped to capture images at a consistent time interval instead of using distance. This function can be useful ifyou want to capture images over an area without planning a mission. This time-based imaging results in more images per area, and therefore more processing time and storage cost. See the Trigger Type options on page xx to enable time-based imaging. Overlap and Sidelap To capture images for the map, the aircraft flies a lawnmower-like pattern in strips across the survey site. The front-to-back overlap between sequential images is called overlap; the side overlaps of adjacent pictures in different strips is called sidelap. The overlap and sidelap parameters in the Survey tool (see Advanced Options page xx) determine the distance between images and the number of imagesto be captured based on the projected ground area that each image will cover, called a footprint. Increasing overlap and sidelap improves the accuracy ofthe map while increasing flight time and processing time.

In theSurvey tool,

# 3DREAI 3DR EAI is based on KAP UAV Exposure Control Script v3.1: a great open-source project for kite and UAV aerial photography. 

### Start and Stop Script Ensure the camera is set to P (program) mode before powering the camera. Upon startup, 3DR EAI starts automatically and listens for commands from the autopilot, indicated by 

### waitingforUSBsignal. To stop (and re-start) the script, pressthe shutter button. The script will display INTERRUPTED when stopped.

Script start: waiting on USB signal

Script stopped: INTERRUPTED FINISHED
