SECTION 1 GENERAL NOTE: Inan effort to minimize costs and maximize spare parts availability, many COTS (commercial off the shelf) components have been utilized. Some may have slight modifications to better suit this application. Most COTS products have separate data sheets, assembly manuals and instruction manuals.As with all high technology products utilizing constantly evolving software, itis important to periodically check for online upgrades tothe COTS components, including hardware, firmware and software. WARNING: Great care must be taken with the batteries. Much ofthis manual and supplemental information is devoted tothe use and care ofthe batteries, especially the flight batteries. They are less volatile than gasoline, though they should be treated with

the same respect. Become very familiar with proper techniques of their use. GENERAL CHARACTERISTICS o Economical due to extensive useof COTS products o Low Visual Signature 00000 Quick Launch and Recovery Short Training Period Simple OperationWaypoint Navigation

Improper charging, vibration, impact, high discharge, etc. can lead to explosion and fire. Batteries must be charged under constant supervision and using proper precautions. o Batteries fully charged must be handled with extreme care. o Batteries must not be stored above 60% charged state. o Store batteries between 20%-60% charged state. Fully charge just before use. o Fully charged batteries which are not tobe used within 24 hours should be discharged to 20%- 50% charged state. o Discharging LiPoly batteries in excess of 80% of their rated capacity can cause harm tothe batteries. o Using more than one battery ata time requires the proper wiring harness so that the voltage isno more than 16.8V. Over voltage will cause serious damage to electrical equipment. PILOT OPERATIONS HANDBOOK PAGEI2/I\I\ 00000 Using more than one battery ata time requires weight and balance checks. Proper CGis critical to performance. Airframe must not be overloaded. GPS/Compass must be facing forward. Do not use GPS Mode without GPS lock. oUse low strength thread locking compound onall screws. Wireless Video and Data ranges vary considerably on many factors including weather, equipment, and obstructions. PILOT OPERATIONS HANDBOOK PAGEI3/\ SECTION 2 LIMITATIONS AIRSPEED LIMITATIONS Vne- Velocity to Never Exceed: 15m/s oVa- Typical Maneuvering Speed- 5m/s POWER & POWERPLANT LIMITATIONS o 40 Amps max per motor o 40 Amps max per speed control o 320 Amps max total o Do not exceed 80-90% discharge of rated battery capacity o Do not charge batteries which are warmer than air temperature. o Allow batteries to cool after use before charging. Leave anair gap between batteries when multiple batteries are used simultaneously WEIGHT LIMITS o Takeoff Weight Max: 10lbs o Must be checked prior to takeoff ifany change in equipment is made. CENTER OF GRAVITY LIMITS 0 3mm from the center of any ofthe three pairs of arms 0 Must be checked before every flight to ensure batteries were installed inthe proper location. Check all four pairs of arms before flight. MANEUVER LIMITS This aircraft is intended for non-aerobatic operations. o G-loading maximum: 2G TEMPERATURE LIMITS o Operating Temp Range: -1ooc to +40°C In cold temperatures: o Keep IMU at room temperature if possible before the flight. o Keep Batteries above 5°C before flight. o Do notfly with any frost oriceon the propellers oIn warm temperatures. o Batteries heat up when discharged. o The higher the discharge rate the higher the temperature increase during use. o At temperatures above 45°C, useof2or more batteries is required to lower the load on any one battery pack to keep it cooler. PILOT OPERATIONS HANDBOOK PAGEI4(\ WEATHER LIMITS Light dust and light rain require the useofa cover for the electronics inthe center section. RANGE LIMITS Battery capacity isa primary limiting factor.

Flying into the wind will use more battery power to travel the same ground distance. Higher air speeds will be required to penetrate the wind which used more battery power. Take this into account when flying a mission. Where possible, fly upwind atthe start ofa mission and downwind atthe end to avoid depleting the battery before returning to base. Have alternative landing sites available in case of emergency landing. WIRELESS LINK o Wireless links will be stable inLOS (line of sight) in most conditions. o Wireless links are always susceptible to shorter ranges due to atmospheric conditions.•••••• Other transmission devices inthe area Jamming Antennas not aligned properly Improper voltage Antenna blockage from AVin certain positions Multipath - reflection off buildings or ground which cause multiple signals to arrive at different times and/or phase. PILOT OPERATIONS HANDBOOK PAGEI5SECTION 3 EMERGENCY PROCEDURES MOTOR FAILURE o Operation is possible with one motor/ESC/propeller failure. o The two adjacent motors/ESCs will be increased in thrust automatically by the flight controller to overcome the loss. o In cases where the airframe is highly loaded the maximum rating of40 amps may be exceeded by these two motors/ESCs. o Operation should be terminated as soon as possible to reduce the possibility of damage tothe remaining motors. COMMUNICATION FAILURE o Video link failure. o 5.8 Ghz being the shortest wavelength in general UAVuse has the least ability to penetrate. This link should be the firsttobe lost. o Itisbest to lose video first!Itisthe least likely to cause a crash when itfails. o 5.8 Ghz can lose link with little warning. o Ensure that the GCS station antennas are perpendicular tothe UAV. Do not point the antenna atthe AV. o Yaw the AVto change the antenna position o Other links should stillbe good. Return back tothe GCS until linkis restored. o Transmitters produce heat when in operation. When overheated they may have thermal protection which interrupts use temporarily. Useofa heat sinkorfan may be required especially with high ambient temperatures. o Higher gain antennas may be used, but doso with caution. High gain antennas are directional. o Multiple antennas using "diversity" can be used. Diversity isa device which determines the best signal, and uses that. o 5.8 Ghz even at high wattages theoretically has less range than lower frequencies. o RC link failure o 2.4 Ghz antennas can lose link with little warning. o Anything in between the two antennas can cause temporary signal loss especially a person. o Hold the transmitter upinthe air and walk inthe general direction ofthe AV (aerial vehicle). o Ensure that the antenna is vertical. Do not point the antenna atthe AV. o The failsafe's on the RC link should besetso that the AV returns to home. Should this require a heading change, the antenna may move intoa more desirable position and link will be restored. o The onboard equipment may block the signal. Yaw the AVso that the antennas point towards the GCS. PILOT OPERATIONS HANDBOOK PAGEI6LOW BATTERY POWER o Fail-safes can beset such that inthe event oflow battery power, either due toa failure or too long ofa flight, the warning light on theAVwill constantly flash amber. Thisisthe first level of warning. o The second warning levelisred flashing lights o Landing with 80-90% of battery depleted is best. o Do not mix partially charged batteries. Only use completely charged batteries. GCS FAILURE o Takeover by the external pilot should happen ASAP using the RC link. o Most often happens due toalow battery. o Keep a spare 3cell LiPoly battery with the appropriate plug to plug into the charge jack for emergency use. Most chargers are 19V output which is roughly equivalent toa 4-cell battery. 3-cell batteries may work. COMPASS CALIBRATION ERROR o Ifthe compass isoutof calibration the warning light will flash red. Thisisthe same signal as low voltage. Ifthe voltage is correct, there isa calibration error. o Recalibrate the compass following the instruction manual. FIREo Fires can occur due toa short circuit or battery failure. o Disconnect the battery ASAP unless there is danger in doing soif there isany electrical issue. o Itisnot possible toput outa battery fire. o Do not attempt to put outa battery fire. Useafire extinguisher to put out fires surrounding the battery. A C02 fire extinguisher is better than the powder or chemical type. C02 does not leave a residue. Water can be used though itmay cause other electrical component failures. FORCED LANDINGS o If alternate emergency landing zones should be chosen ahead of time. o Be sure that theLZis clear of people to avoid any incidents. o Land inthe nearest LZ which is clear of people. o Announce your intentions of landing as loud as necessary to alert people ofthe incoming AV. PILOT OPERATIONS HANDBOOK PAGEI7( SECTION 4- SETUP SUGGESTIONS GPS/COMPASS MAST LENGTH o We found that the higher the mast, the better the GPS reception. RADIO SETUP o Follow the instructions inthe manual. TIMERSo Use ofthe countdown timer isa good backup method to ensure landing with battery power. o Set the timer for10 minutes (or what you deem appropriate) and have itstart when the throttle is over **\~.** Then adjust the timer upwards until the amount of battery used is about 80-90% ofthe total available.

BATTERIESo Replace the transmitter standard battery witha Lipoly battery to extend use times

to eight hours. Supplied batteries often last about two hours. NORMAL PROCEDURES PREFLIGHT CHECKLIST o Confirm all communication radios are operational. o Area must be clear of people to avoid collision. o Check for overhead power lines and other obstacles to avoid. o Check structural integrity. o In event of prior crash, inspect all booms, props, and motor mounts for excessive flex indicating structural fatigue/failure. o Have a manual flight plan avoiding obstacles. o Load auto flight planif using one. o Be sure that the total flight timeis under 15 minutes to avoid low battery. o Clean lens. o Remove lens cap. o Ensure camera has SO card installed. o Many flights have been wasted due tothis! olnstall batteries. o Ensure that the straps are tight and the Velcro keeps the batteries from moving which will avoid ashiftinthe CG (Center of Gravity- or thatit balances evenly). o Check CG (Center of Gravity). o Lift the copter on each of the two pairs of arms. The copter should balance properly. Ifnot, do not fly. Rearrange the equipment such that the CGisoIMU pointing forward. o The Inertial Measurement Unitissetso thatit must face forward oGPS/Compass PILOT OPERATIONS HANDBOOK 81PAGEinstalled, limited free play, pointing forward. o This device must be installed with a screw to hold itin place. It cannot vibrate easily. Ifit does not point forward, the corrections inATTI and GPS mode will be incorrect anditwill crash. The FCwill provide a warning with constant flashing white lights. o Level copter using a bubble level with front pointing in correct direction for course lock- do not turn on. o Keep in mind the best angle for pointing the landing gear inthe direction that will keep the landing gear outofthe shot when flying. • Turn on Pilot Tx • Confirm transmitter switch settings. • Check Model Selection onTxtobe Surv 800 oThrottle onTx Down. • Return to Home switch off. o These settings above are required to initialize the copter properly. Ifthe switches areinthe incorrect position, itwill not initialize properly. o Ifthe copter does not function properly after takeoff, land immediately and disconnect the copter power. Then putallthe switches inthe proper position for initialization and turn the power back ontothe copter. o Do not move or vibrate the copter until 30 seconds after full GPS Lock. o Initial 3red blinks is normal meaning no GPS lock. No red flashes indicates full GPS lock. 000000000 Continue with checklist as you are waiting forfull GPS lock, but do not move the copter.Ifthe GPS takes more than 5 minutes to lock, there isa problem with the area. Itis not receiving the proper signals from the satellites. GPS signals are weak, so trees, people, buildings, terrain, weather, have an effect. Move the copter intoa more open area where itcan more easily see the satellites. The transmitters receive a signal from the corresponding receivers. The voltages are regulated to about 5v.Ifthe voltage is below 4.4v or above 6vdo notfly. There may be power regulation issues. The receivers cannot work outside this voltage consistently. Also there is some issue ifthe voltage is outside that range which should be resolved before flying. Engage Attitude Mode- Must achieve double amber flash. Engage GPS Mode- Must achieve double purple flash Do not engage motors.

Center the trim such that when the stickisinthe neutral position that there are

equal numbers of clicks in each direction. This ensures that when the sticks are neutralized that the flight controller will recognize this signal and engage GPS mode. Calibrate GPS/Compass before the first flight each day orif receiving continuous red blinks or continuous white blinks. Flip the GPS mode switch 7 times very quickly from manual to GPS. End with the switch inthe manual position. The indicator light will be blue. Rotate the copter about.1.5 turns ina horizontal position. A green flashing light indicates that thisis complete. Then hold the copter vertically and rotate about 1.5 turns. A white PILOT OPERATIONS HANDBOOK 9IPAGE(''- flashing light indicates that thisis complete. Repeat if necessary until thisis completed.• After calibration, reset the copter by cycling battery with copter pointed in

the correct heading for course lock. • Engage Camera. • HDMI switch On. o This will stop video from playing onthe back ofthe camera and will send the video signal tothe video transmitter via the HDMI connection. o This allows the camera tobe operated freely through the transmitter. o Verify camera operation. o Operate the shutter. o Set the focus to auto. o Verify data linkif installed. o Roll the copter about 45 degrees onits side by lifting one side ofthe copter and resting one side ofthe landing gear on the ground. o A corresponding roll should be seen on the gauge. o Ifthe copter is rolled tothe right, itwill appear on the gauge that the horizon rolls tothe left- not the right because the view from inside the copter isthat the horizon rolls the opposite direction ofthe copter. 000 Verify altitude is about 0via gauge on computer. Ifitisnot about 0,the altitude settings for the waypoints will beoffbythis amount. This could cause the copter toflyat10 meters or30 meters ifthe waypoint isset for20 meters and the altitude isoffby10 meters one way or another. Ifthe copter thinks itisat10 meters when itison the ground, thenitwill only rise10 meters above the ground to achieve what it believes ittobe20 meters above the ground. The altitude can be reset using the ground control software by going to altitude offset. o Alternate Emergency Landing Sites Established. NORMAL TAKEOFF 000000000 Engage GPS mode- Double purple flash when the throttle is down instances. Announce loudly: "CLEAR PROP" Move both ofthe sticks tothe bottom left corners to engage the motors. Within 1 second move the throttle up1/8- 1I4.The copter should notliftoff until about V2 stickis reached. Verify data and video links before lifting off.If anything isnot working properly, move the throttle stick tolowto disengage the motors and determine a solution. Ifall flight checks are passed, announce loudly: "TAKING OFF" Advance throttle to about 3/4. Copter must jump offofthe ground to avoid one skid coming up before the other skid, and the skid on the ground getting caught and flipping the copter over sideways. Ascend to3 meters. Then decrease throttle toV2to engage the GPS hold. Verify links, GPS, Attitude, etc. Should be single purple flash. Verify that the copter is holding position within .5minall directions. PILOT OPERATIONS HANDBOOK 10IPAGEo Verify camera operation. o Verify copter stability. If unstable, land and reset gains, recalibrate, or retest as necessary. o Proceed with manual mission or;For autopilot operation o Ascend to10 meters. o Quick decisions are required when red flashes are indicated. o 10 seconds or more oflossof GPS signal will stop waypoint guidance and any GPS hold and put into manual mode. o Red indicator light battery warning requires immediate landing. POST LANDING o Note battery power used during the flight. Write this down inthe log book. o ALWAYS disconnect the main power tothe UAVfirst, then turn off the transmitter. o Check motor temperatures by touching them with your fingers. Any motors which are excessively hot should be further inspected and possibly replaced. o Check battery temperatures by touching them with your fingers. • Battery temperatures should not be hottothe touch. • Battery temperatures should be slightly above ambient. o Inspect all components especially the propellers for wear. o Note in logbook which batteries were used to calculate life cycle. o Remove the props using the "quick-disconnects" for return storage in case.

Include the following: • Aircraft flown • Aircraft serial number • Date • Time of Day • Time in Operation (in hours) • Location • Flight Objective • Remarks \ PILOT OPERATIONS HANDBOOK 12IPAGESECTION 5- PERFORMANCE FLIGHT TIMES o The UAVis designed to hover at high efficiency. Hovering is much less efficient than flying ona wing, thus flight times are low compared to fixed wing aircraft. o Allthe weight ofthe UAVis supported by power from the batteries. Asthe batteries are used ina flight, the amount of power available decreases. Therefore, the power reserve is constantly decreasing asthe battery is being used. Thus loading a rotorcraft above its limitisnot recommended. While the UAV may have enough power toliftoff initially onafull charge, the power reserve at partial charge may be too lowto allow for maneuvering and will result ina crash. o High lateral speeds will add liftto slightly improve efficiency. The rotors act similar to fixed wings at higher speeds. This increase in efficiency may be negated bythe increased power consumption of forward flight. o High winds or gusts decrease efficiency /flight time. The motors work harder to hold position. o As weight increases flight times decrease. WIRELESS TRANSMISSION o Refer tothe specific manuals for performance ratings. o Wireless communications utilized provide acceptable communication for LOS (loss of signal). o In general: • LOSis required. • The higher the GCS antennas, the better the range. • Any freq. at may have severe degradation due to location to other admitters such ascell towers. • RSSI (Received Signal Strength Indication) should be monitored for indication of communication drop out. PILOT OPERATIONS HANDBOOK 131 PAGESECTION 6- WEIGHT AND BALANCE EQUIPMENT LIST o CGis critical tothe efficient operation of any AV. o When components are shifted, the CG will be altered. o The main components which are moved ona regular basis are the sensors and the batteries. o The sensors are typically inthe front ofthe AV, and the batteries are located inthe correct position to offset allthe components on theAV. o The CG must be tested after any change tothe components or their placement. o The CG should be tested by lifting the UAVwith fingers on the bottom ofthe arms. WEIGHT Check all three pairs of arms. The CG should beno more than 2mm offinany on the three checks. The closer the CGistothe centerlines of the arms the more efficient and the more stable the UAV will be. o Weight is critical tothe operation of any aircraft. o Weight is especially critical toa rotor wing aircraft. Atfull throttle the motors have a finite amount of thrust. All the weight is lifted by the battery power, there isno wing to assist in providing lift. o As the batteries are operated, they lose power. Atfull charge they have about 16.8v. At 20% remaining capacity they have about 14.0v. o Do not overload the aircraft or there will not be sufficient reserve power to maneuver atlow battery levels. PILOT OPERATIONS HANDBOOK 14IPAGE( I SECTION 7- AIR VEHICLE AND SYSTEMS DESCRIPTION FLIGHT BATTERY REQUIRED o Manufacturers: Various COTS suppliers. o Battery chemistry recommended: Lithium Polymer. o Battery Capacity: upto 16,000 mah or greater depending on max gross weight. o Battery cell count required: 4S(4 cells in series) o Battery Voltage: 14V minimum during hover, nominal, 16.8V maximum. o Battery Minimum Rated Discharge Rate: 20C minimum. o Battery Minimum Charge Rate: 1 C (2C preferable) o Battery Rest Time between discharging and charging: 0-30 minutes. o Batteries used simultaneously: Typically 1 o Recommended Battery Discharge Amount: 80-90% WIRELESS COMMUNICATIONS o Refer tothe specific manuals for performance ratings. o Never power a video transmitter or receiver without an antenna connected or overload failure will occur. o Wireless communications utilized provide acceptable communication for LOS. o In general: • LOSis required. o Lower frequencies penetrate objects such as trees better than higher freqs. o Lower freqs have longer range than high freqs. o Higher freqs can transfer more data than lower freqs. o Higher freqs use smaller/shorter antennas. o The higher the GCS antennas, the better the range and reception. o Any freq at may have severe degradation due to location to other admitters such ascell towers. o Range must be constantly monitored. o Alternate antenna types may be utilized to improve link/range. Patch, helical, omni, etc. can be substituted. They must be verified before use. o Alternate freqs may be utilized to improve link/range. PILOT OPERATIONS HANDBOOK 151 PAGESECTION 8 HANDLING, SERVICE AND MAINTENANCE PROPELLER CARE o Propellers must be checked each flight for nicks or cracks. o Propellers are designed tolast indefinitely ifthey do not impact dust, dirtor more. BATTERY CARE AND USE Refer to instruction sheet included from the battery manufacturer. Typical information follows:o Batteries are highly flammable and can explode, especially when fully charged. Improper charging, vibration, impact, high discharge, etc. can lead to explosion and fire. o Batteries must be charged under constant supervision and using proper precautions. o Batteries fully charged must be handled with extreme care. o Any battery which puffs upis considered damaged and must not be used. Itisin a dangerous state. Never charge a puffed up battery. o Any battery which holds less than 80% ofits rated capacity should be discarded. o Cycle test each battery after every 50 cycles orifa battery is suspected to have lostas significant amount ofits capacity to determine the current capacity. o Properly dispose of batteries. First discharge the battery fully using a battery cycler. Bring toa recycler such asa home improvement store. o Always charge flight batteries under "balance" mode. o Flight Battery Recommended Charge- Rate: 1 C which takes approximately 1hour to charge. o Flight Battery Maximum Charge Rate: May exceed 5C. Charge rates higher than 1 Cwill decrease life cycles. Maximum charge rating per the manufacturer will provide 300+ cycles. Use the lowest charge rate which is practical. o Battery Rest Time between discharging and charging: 30 minutes minimum, 1hour maximum. 0000000 Do not charge ifthe battery is more than 2°C warmer than ambient, especially if the temperature is above 20°C. The outer surface is cooler than the inner core after use. Damage will occur when charging a warm battery. Recommended Battery Discharge Amount: 80%. Using more ofthe capacity of the battery will decrease the life cycles

As battery temperature approaches freezing the capacity of Lithium Polymer batteries decrease. Keep warmer than 5°C before installing into the UAV (unmanned aerial vehicle). Battery capacity decreases at higher discharge rates. Using more batteries decreases the discharge rate of each battery thereby extending individual battery capacity slightly.

Lower discharge rates improve the life cycles. Batteries are rated at greater than 300 life cycles. 1,000+ life cycles are possible. Batteries must not be stored above 60% charged state for extended periods. PILOT OPERATIONS HANDBOOK 16IPAGE(\ o Batteries should be stored below 25°C for extended periods. o Store batteries between 40%- 60% charged state. Fully charge just before use. o Fully charged batteries which are not tobe used within 24 hours should be discharged to 40%- 60% charged state using the battery discharger. PREVENTATIVE MAl NTENANCE ANNUAL INSPECTION (SUGGESTED) o Ifthe airframe hasin excess of300 hours inaone year period, an annual inspection must be completed byan approved technician. o An approved technician should disassemble the UAVand inspect all components for wear and replace any components as required. o Test all batteries for capacity. o Upgrade firmware and software to latest revisions 500 HOUR PM (SUGGESTED) o An approved technician should disassemble the UAVand inspect all components for wear and replace any components as required. o Replace all motors. o Test all batteries for capacity. o Upgrade firmware and software to latest revisions.

PILOT OPERATIONS HANDBOOK PAGEI4(\ WEATHER LIMITS Light dust and light rain require the useofa cover for the electronics inthe center section. RANGE LIMITS Battery capacity isa primary limiting factor.

Flying into the wind will use more battery power to travel the same ground distance. Higher air speeds will be required to penetrate the wind which used more battery power. Take this into account when flying a mission. Where possible, fly upwind atthe start ofa mission and downwind atthe end to avoid depleting the battery before returning to base. Have alternative landing sites available in case of emergency landing. WIRELESS LINK o Wireless links will be stable inLOS (line of sight) in most conditions. o Wireless links are always susceptible to shorter ranges due to atmospheric conditions.• Other transmission devices inthe area • Jamming • Antennas not aligned properly ••• Improper voltage Antenna blockage from AVin certain positions Multipath -reflection off buildings or ground which cause multiple signals to arrive at different times and/or phase. PILOT OPERATIONS HANDBOOK PAGEI5SECTION 3 EMERGENCY PROCEDURES MOTOR FAILURE o Operation is possible with one motor/ESC/propeller failure. o The two adjacent motors/ESCs will be increased in thrust automatically by the flight controller to overcome the loss. o In cases where the airframe is highly loaded the maximum rating of40 amps may be exceeded by these two motors/ESCs. o Operation should be terminated as soon as possible to reduce the possibility of damage tothe remaining motors. COMMUNICATION FAILURE o Video link failure. o 5.8 Ghz being the shortest wavelength in general UAVuse has the least ability to penetrate. This link should be the firsttobe lost. o Itisbest to lose video first!Itisthe least likely to cause a crash when itfails. o 5.8 Ghz can lose link with little warning. o Ensure that the GCS station antennas are perpendicular tothe UAV. Do not point the antenna attheAV. o Yaw the AVto change the antenna position o Other links should stillbe good. Return back tothe GCS until linkis restored. o Transmitters produce heat when in operation. When overheated they may have thermal protection which interrupts use temporarily. Useofa heat sinkorfan may be required especially with high ambient temperatures. o Higher gain antennas may be used, but doso with caution. High gain antennas are directional. o Multiple antennas using "diversity" can be used. Diversity isa device which determines the best signal, and uses that. o 5.8 Ghz even at high wattages theoretically has less range than lower frequencies. o RC link failure o 2.4 Ghz antennas can lose link with little warning. o Anything in between the two antennas can cause temporary signal loss especially a person. o Hold the transmitter upinthe air and walk inthe general direction ofthe AV (aerial vehicle). o Ensure that the antenna is vertical. Do not point the antenna atthe AV. o The failsafe's on the RC link should besetso that the AV returns to home. Should this require a heading change, the antenna may move intoa more desirable position and link will be restored. o The onboard equipment may block the signal. Yaw the AVso that the antennas point towards the GCS. PILOT OPERATIONS HANDBOOK PAGEI6/(\ LOW BATTERY POWER o Fail-safes can beset such thatinthe event oflow battery power, either due toa failure or too long ofa flight, the warning light on theAVwill constantly flash amber. Thisisthe first level of warning. o The second warning levelisred flashing lights o Landing with 80-90% of battery depleted is best. o Do not mix partially charged batteries. Only use completely charged batteries. GCS FAILURE o Takeover by the external pilot should happen ASAP using the RC link. o Most often happens due toalow battery. o Keep a spare 3cell LiPoly battery with the appropriate plug to plug into the charge jack for emergency use. Most chargers are 19V output which is roughly equivalent toa 4-cell battery. 3-cell batteries may work. COMPASS CALIBRATION ERROR 00FIRE0000 Ifthe compass isoutof calibration the warning light will flash red. Thisisthe same signal as low voltage. Ifthe voltage is correct, there isa calibration error. Recalibrate the compass following the instruction manual. Fires can occur due toa short circuit or battery failure. Disconnect the battery ASAP unless there is danger in doing soif there isany electrical issue. Itisnot possible toput outa battery fire. Do not attempt to put outa battery fire. Useafire extinguisher to put out fires surrounding the battery. A C02 fire extinguisher is better than the powder or chemical type. C02 does not leave a residue. Water can be used though itmay cause other electrical component failures. FORCED LANDINGS o If alternate emergency landing zones should be chosen ahead of time. o Be sure that theLZis clear of people to avoid any incidents. o Land inthe nearest LZ which is clear of people. o Announce your intentions of landing as loud as necessary to alert people ofthe incoming AV. PILOT OPERATIONS HANDBOOK PAGEI7SECTION 4- SETUP SUGGESTIONS GPS/COMPASS MAST LENGTH o We found that the higher the mast, the better the GPS reception. RADIO SET UP o Follow the instructions inthe manual. TIMERSo Use ofthe countdown timer isa good backup method to ensure landing with battery power. o Set the timer for10 minutes (or what you deem appropriate) and have itstart when the throttle is over 1k Then adjust the timer upwards until the amount of battery used is about 80-90% ofthe total available.

BATTERIESo Replace the transmitter standard battery witha Lipoly battery to extend use times

to eight hours. Supplied batteries often last about two hours. NORMAL PROCEDURES PREFLIGHT CHECKLIST o Confirm all communication radios are operational. o Area must be clear of people to avoid collision. o Check for overhead power lines and other obstacles to avoid. o Check structural integrity. o In event of prior crash, inspect all booms, props, and motor mounts for excessive flex indicating structural fatigue/failure. o Have a manual flight plan avoiding obstacles. o Load auto flight plan if using one. o Be sure that the total flight timeis under 15 minutes to avoid low battery. o Clean lens. o Remove lens cap. o Ensure camera has SD card installed. o Many flights have been wasted due tothis! olnstall batteries. o Ensure that the straps are tight and the Velcro keeps the batteries from moving which will avoid ashiftinthe CG (Center of Gravity- or thatit balances evenly). o Check CG (Center of Gravity). o Lift the copter on each of the two pairs of arms. The copter should balance properly. Ifnot, do not fly. Rearrange the equipment such that the CGisoIMU pointing forward. o The Inertial Measurement Unitissetso thatit must face forward oGPS/Compass PILOT OPERATIONS HANDBOOK 81 PAGEinstalled, limited free play, pointing forward. o This device must be installed with a screw to hold itin place. It cannot vibrate easily. Ifit does not point forward, the corrections inATTI and GPS mode will be incorrect anditwill crash. The FCwill provide a warning with constant flashing white lights. o Level copter using a bubble level with front pointing in correct direction for course lock- do not turn on. o Keep in mind the best angle for pointing the landing gear inthe direction that will keep the landing gear outofthe shot when flying. • Turn on Pilot Tx • Confirm transmitter switch settings. • Check Model Selection onTxtobe Surv 800 oThrottle onTx Down. • Return to Home switch off. o These settings above are required to initialize the copter properly. Ifthe switches areinthe incorrect position, itwill not initialize properly. o Ifthe copter does not function properly after takeoff, land immediately and disconnect the copter power. Then putallthe switches inthe proper position for initialization and turn the power back ontothe copter. o Do not move or vibrate the copter until 30 seconds after full GPS Lock. o Initial 3red blinks is normal meaning no GPS lock. No red flashes indicates full GPS lock. o Continue with checklist as you are waiting forfull GPS lock, but do not move the copter. o Ifthe GPS takes more than 5 minutes to lock, there isa problem with the area. Itis not receiving the proper signals from the satellites. GPS signals are weak, so trees, people, buildings, terrain, weather, have an effect. Move the copter intoa more open area where itcan more easily see the satellites. o The transmitters receive a signal from the corresponding receivers. The voltages are regulated to about 5v.Ifthe voltage is below 4.4v or above 6vdo notfly. There may be power regulation issues. The receivers cannot work outside this voltage consistently. Also there is some issue ifthe voltage is outside that range which should be resolved before flying. o Engage Attitude Mode- Must achieve double amber flash. o Engage GPS Mode- Must achieve double purple flash Do not engage motors. o Center the trim such that when the stickisinthe neutral position that there are equal numbers of clicks in each direction. This ensures that when the sticks are neutralized that the flight cohtroller will recognize this signal and engage GPS mode. o Calibrate GPS/Compass before the first flight each day orif receiving continuous red blinks or continuous white blinks. o Flip the GPS mode switch 7 times very quickly from manual to GPS. End with the switch inthe manual position. The indicator light will be blue. Rotate the copter about. o 1.5 turns ina horizontal position. A green flashing light indicates that thisis complete. Then hold the copter vertically and rotate about 1.5 turns. A white PILOT OPERATIONS HANDBOOK 9IPAGEflashing light indicates that thisis complete. Repeat if necessary until thisis completed.• After calibration, reset the copter by cycling battery with copter pointed in

the correct heading for course lock. • Engage Camera. • HDMI switch On. o This will stop video from playing on the back ofthe camera and will send the video signal tothe video transmitter via the HDMI connection. o This allows the camera tobe operated freely through the transmitter. o Verify camera operation. o Operate the shutter. o Set the focus to auto. o Verify data linkif installed. o Roll the copter about 45 degrees onits side by lifting one side ofthe copter and resting one side ofthe landing gear on the ground. o A corresponding roll should be seen on the gauge. o Ifthe copter is rolled tothe right, itwill appear on the gauge that the horizon rolls tothe left- not the right because the view from inside the copter isthat the horizon rolls the opposite direction ofthe copter. 0 Verify altitude is about 0via gauge on computer. 0 Ifitisnot about 0,the altitude settings for the waypoints will beoffbythis amount. This could cause the copter toflyat10 meters or30 meters ifthe waypoint isset for20 meters and the altitude isoffby10 meters one way or another. Ifthe copter thinks itisat10 meters when itisonthe ground, thenitwill only rise10 meters above the ground to achieve what it believes ittobe20 meters above the ground. 0 The altitude can be reset using the ground control software by going to altitude offset. o Alternate Emergency Landing Sites Established. NORMAL TAKEOFF o Engage GPS mode- Double purple flash when the throttle is down instances. o Announce loudly: "CLEAR PROP" o Move both ofthe sticks tothe bottom left corners to engage the motors. Within 1 second move the throttle up 1/8- 1/4. The copter should notliftoff until about 112 stickis reached. o Verify data and video links before lifting off.If anything isnot working properly, move the throttle stick to lowto disengage the motors and determine a solution. o Ifall flight checks are passed, announce loudly: "TAKING OFF" o Advance throttle to about 3/4. Copter must jump offofthe ground to avoid one skid coming up before the other skid, and the skid on the ground getting caught and flipping the copter over sideways. o Ascend to3 meters. Then decrease throttle toY2to engage the GPS hold. o Verify links, GPS, Attitude, etc. Should be single purple flash. o Verify that the copter is holding position within .5minall directions. PILOT OPERATIONS HANDBOOK 10IPAGE( o Verify camera operation. o Verify copter stability. If unstable, land and reset gains, recalibrate, or retest as necessary. o Proceed with manual mission or;For autopilot operation o Ascend to10 meters. o Quick decisions are required when red flashes are indicated. o 10 seconds or more oflossof GPS signal will stop waypoint guidance and any GPS hold and put into manual mode. o Red indicator light battery warning requires immediate landing. POST LANDING 000 Note battery power used during the flight. Write this down inthe log book. ALWAYS disconnect the main power tothe UAV first, then turn off the transmitter.

Check motor temperatures by touching them with your fingers. Any motors which are excessively hot should be further inspected and possibly replaced. 000 Check battery temperatures by touching them with your fingers. • Battery temperatures should not be hottothe touch. • Battery temperatures should be slightly above ambient. Inspect all components especially the propellers for wear. Note in logbook which batteries were used to calculate life cycle. 0 Remove the props using the "quick-disconnects" for return storage in case.

Hovering is much less efficient than flying ona wing, thus flight times are low compared to fixed wing aircraft. o Allthe weight ofthe UAVis supported by power from the batteries. Asthe batteries are used ina flight, the amount of power available decreases. Therefore, the power reserve is constantly decreasing asthe battery is being used. Thus loading a rotorcraft above its limitisnot recommended. While the UAV may have enough power toliftoff initially onafull charge, the power reserve at partial charge may be too lowto allow for maneuvering and will result ina crash. o High lateral speeds will add liftto slightly improve efficiency. The rotors act similar to fixed wings at higher speeds. This increase in efficiency may be negated bythe increased power consumption of forward flight. o High winds or gusts decrease efficiency/flight time. The motors work harder to hold position. o As weight increases flight times decrease. WIRELESS TRANSMISSION o Refer tothe specific manuals for performance ratings. o Wireless communications utilized provide acceptable communication for LOS (loss of signal). o In general: • LOSis required. • The higher the GCS antennas, the better the range. • Any freq. at may have severe degradation due to location to other admitters such ascell towers. • RSSI (Received Signal Strength Indication) should be monitored for indication of communication drop out. PILOT OPERATIONS HANDBOOK 131 PAGE( SECTION 6- WEIGHT AND BALANCE EQUIPMENT LIST o CGis critical tothe efficient operation of anyAV. o When components are shifted, the CG will be altered. o The main components which are moved ona regular basis are the sensors and the batteries. o The sensors are typically inthe front ofthe AV, and the batteries are located inthe correct position to offset allthe components on the AV. o The CG must be tested after any change tothe components or their placement. o The CG should be tested by lifting the UAVwith fingers on the bottom ofthe arms. WEIGHT Check all three pairs of arms. The CG should beno more than 2mm offinany on the three checks. The closer the CGistothe centerlines ofthe arms the more efficient and the more stable the UAVwill be. o Weight is critical tothe operation of any aircraft. o Weight is especially critical toa rotor wing aircraft. Atfull throttle the motors have a finite amount of thrust. All the weight is lifted by the battery power, there isno wing to assist in providing lift. o As the batteries are operated, they lose power. Atfull charge they have about 16.8v. At 20% remaining capacity they have about 14.0v. o Do not overload the aircraft or there will not be sufficient reserve power to maneuver at low battery levels. PILOT OPERATIONS HANDBOOK 14jPAGE( SECTION 7- AIR VEHICLE AND SYSTEMS DESCRIPTION FLIGHT BATTERY REQUIRED o Manufacturers: Various COTS suppliers. o Battery chemistry recommended: Lithium Polymer. o Battery Capacity: upto 16,000 mah or greater depending on max gross weight. o Battery cell count required: 4S(4 cells in series) o Battery Voltage: 14V minimum during hover, nominal, 16.8V maximum. o Battery Minimum Rated Discharge Rate: 20C minimum. o Battery Minimum Charge Rate: 1 C (2C preferable) o Battery Rest Time between discharging and charging: 0-30 minutes. o Batteries used simultaneously: Typically 1 o Recommended Battery Discharge Amount: 80-90% WIRELESS COMMUNICATIONS o Refer tothe specific manuals for performance ratings. o Never power a video transmitter or receiver without an antenna connected or overload failure will occur. o Wireless communications utilized provide acceptable communication for LOS. o In general: • LOSis required. o Lower frequencies penetrate objects such as trees better than higher freqs. o Lower freqs have longer range than high freqs. o Higher freqs can transfer more data than lower freqs. o Higher freqs use smaller/shorter antennas. o The higher the GCS antennas, the better the range and reception. o Any freq at may have severe degradation due to location to other admitters such ascell towers. o Range must be constantly monitored. o Alternate antenna types may be utilized to improve link/range. Patch, helical, omni, etc. can be substituted. They must be verified before use. o Alternate freqs may be utilized to improve link/range. PILOT OPERATIONS HANDBOOK 151 PAGEi\' SECTION 8 HANDLING, SERVICE AND MAINTENANCE PROPELLER CARE o Propellers must be checked each flight for nicks or cracks. o Propellers are designed tolast indefinitely ifthey do not impact dust, dirtor more. BATTERY CARE AND USE Refer to instruction sheet included from the battery manufacturer. Typical information follows:o Batteries are highly flammable and can explode, especially when fully charged. Improper charging, vibration, impact, high discharge, etc. can lead to explosion and fire. o Batteries must be charged under constant supervision and using proper precautions. o Batteries fully charged must be handled with extreme care. o Any battery which puffs upis considered damaged and must not be used. Itisin a dangerous state. Never charge a puffed up battery. o Any battery which holds less than 80% ofits rated capacity should be discarded. o Cycle test each battery after every 50 cycles orifa battery is suspected to have lostas significant amount ofits capacity to determine the current capacity. o Properly dispose of batteries. First discharge the battery fully using a battery cycler. Bring toa recycler such asa home improvement store. o Always charge flight batteries under "balance" mode. o Flight Battery Recommended Charge- Rate: 1 C which takes approximately 1hour to charge. o Flight Battery Maximum Charge Rate: May exceed 5C. Charge rates higher than 1 Cwill decrease life cycles. Maximum charge rating per the manufacturer will provide 300+ cycles. Use the lowest charge rate which is practical. o Battery Rest Time between discharging and charging: 30 minutes minimum, 1hour maximum. 0000000 Do not charge ifthe battery is more than 2°C warmer than ambient, especially if the temperature is above 20°C. The outer surface is cooler than the inner core after use. Damage will occur when charging a warm battery. Recommended Battery Discharge Amount: 80%. Using more ofthe capacity of the battery will decrease the life cycles

As battery temperature approaches freezing the capacity of Lithium Polymer batteries decrease. Keep warmer than 5°C before installing into the UAV (unmanned aerial vehicle). Battery capacity decreases at higher discharge rates. Using more batteries decreases the discharge rate of each battery thereby extending individual battery capacity slightly.

Lower discharge rates improve the life cycles. Batteries are rated at greater than 300 life cycles. 1,000+ life cycles are possible. Batteries must not be stored above 60% charged state for extended periods. PILOT OPERATIONS HANDBOOK 16IPAGE( Batteries should be stored below 25°C for extended periods. 000 Store batteries between 40%- 60% charged state. Fully charge just before use. Fully charged batteries which are not tobe used within 24 hours should be discharged to 40%- 60% charged state using the battery discharger. PREVENTATIVE MAINTENANCE ANNUAL INSPECTION (SUGGESTED) o Ifthe airframe hasin excess of300 hours inaone year period, an annual inspection must be completed byan approved technician. o An approved technician should disassemble the UAVand inspect all components for wear and replace any components as required. o Test all batteries for capacity. o Upgrade firmware and software to latest revisions 500 HOUR PM (SUGGESTED) o An approved technician should disassemble the UAVand inspect all components for wear and replace any components as required. o Replace all motors. o Test all batteries for capacity. o Upgrade firmware and software to latest revisions.
