The Y6

- Scout is a Y configuration hexacopter, multi

- rotor , radio

- controlled, electric powered Unmann ed Aircraft System. The coaxial motor configuration provides redundancy and stability in wind. The UAS is equipped with a multi mode auto pilot flight controller. The UAS flight controller can be operated in one of 3 modes; 1) Attitude stabilization, 2) Attitude stabilization & GPS stabilization, 3) Autonomous mode. It is specifically designed for remote sensing applications in the domains of precision Agriculture, emergency services, and aerial inspection.

(2) Composition. Describe the various materials and where they are used in the construction of the UA. Include details of the fabrication and construction processes

and procedures.

The fuselage and booms of the Y6 Scout are constructed from 3/4” 7073 extruded square aluminum tubing. 14mm diameter holes are machined in the aluminum tubing to reduce weight and allow access to internal wiring. 3mm thick PLA coupling plates bind thePage 2 , 02

b. Navigation.Page 8 , 02

- 08

- 2015

(1) How does the UA determine where it is? How does it navigate to its
intended destination? The Y6

- Scout GPS receiver can track up to 13 GPS satellites to identify its location. When the onboard flight controller auto pilot system is initialized and acquires 6 or more GPS satellites its home position is stored in the auto pilot firm ware system. When utilizing the PC or IPod based flight control computer g round station a sequence of predefined way

- points, max 15, can be up loaded prior to take off and in flight.

(2) How does the pilot respond to the following directions from Air Traffic Control, a visual observer, or other crew member?

(a) Change of aircr aft heading. If a request to change heading is part of the predetermined flight plan, the pilot in command will execute the request. If the request is not part of the predetermined flight plan the request will be considered an emergency maneuver. Emergenc y maneuvers are defined as a maneuvers NOT included in the flight plan. Executing maneuvers not included in the flight plan can result in unanticipated battery consumption. The PIC will asses the impact of the ATC request. The PIC will
either execute the ATC request then resume the flight plan OR notify ATC that the UAS will terminate it flight plan and execute an emergency landing at a predetermined site.

(b) Change of aircraft altitude. If request to change altitude is part of the predetermined fli ght plan the pilot in charge will execute the request. If the request is not part of the predetermined flight plan the request will be considered an emergency maneuver. Emergency maneuvers are defined as a maneuvers NOT included in the flight plan. Execu ting maneuvers not included in the flight plan can result in unanticipated battery consumption. The PIC will asses the impact of the ATC request. The PIC will either execute the ATC request then resume the flight plan OR notify ATC that the UAS

will ter minate its flight plan and execute an emergency landing at a predetermined site.

(3) How does the system identify and respond to a loss of the primary means of navigation? Is there a backup means of navigation? How does the system respond to a

loss of the secondary means of navigation? Primary navigation for the Y6

- Scout is line of sight (LOS). Should the UAS fly beyond LOS the PIC and or copilot can upload new instructions to the UAS, via the ground station, to come back into LOS operations range. If the UAS fly's beyond LOS and the P IC and or copilot are unable to upload new instructions to the UAS the autopilot will engage and the UAS will "return t o home" when

the UAS is more tha n 1000 meters or 3282 feet from its take off location.

(4) Describe the procedures to test the altimeter system (refer to § 91.411). When the auto pilot is initialized altimeter readings are compared to known elevation data.

c. UA Flight Controls.

(1) Describe how the control surfaces respond to commands from the flight control computer. Instructions issu ed to the UAS control surfaces from the ground station control computer provide the same results as instructions issued from the flight control transmitter. In either case the control surfaces respond to current modulation from the Electronic Speed Control lers (ESC). The ESC increase/decrease the rotational speed of the control surface providing pitch, roll, yaw, and thrust.Page 9 , 02

- 08

- 2015

(2) Describe how the pilot provides input to the control system. Flight control input is provided by means of a 2.4 GHz radio tran smitter which interfaces with an on

board receiver connected to the UAS auto pilot. The transmitter has two control sticks, which control directional control via modulation of the ESC. The right hand stick operates the “ elevator ” (pitch control) and “ ailer ons ” (roll control), and the left hand stick operates the throttle, “ rudder ” (yaw control) . The sticks are self centering, except for the throttle. Each stick has an associated trim control lever, which may be used to adjust trim during operation. The U AS does not use a traditional elevator, ailerons, or rudder for control surfaces. However, the Y6

- Scout flight characteristics and pilot operations mimic that of a fixed wing aircraft

. (3) Flight control computer. Via the flight control computer k eyboard the pilot can pause a running flight profile.

(a) Does the flight control computer interface with auxiliary controls that might cause an unintended action? The flight control computer can support an auxiliary transmitter. However, before the aux iliary transmitter can be activated, the pilot in command must physically initialize the auxiliary controller. Procedural safe guards help prevent auxiliary controller from being activated without the pilots knowledge.

(b) Describe the flight control c omputer interfaces required to determine flight status and to issue appropriate commands.

Y6

- Scout ground station computer interfacePage 10 , 02

- 08

- 2015

- 08

- 2015

(4) Does the autopilot employ input limit parameters to keep the aircraft within structural limits? If so, provide a table of these limits. How were these limits
validated?

The flight limits function is default enabled in the NAZA

- M Flight control auto pilot system, it’s aimed to restrict the flying height and distance of the aircraft. The “Max Height” limiter restricts the vertical distance between the aircraft and the home point, the “Max Radius” limiter restricts the horizontal distance between the aircraft and the home point. The default Max Height is 2000m and Max Radius is 2000m. Users can write the values of the “Max Height” and “Max Radius” in the Assistant software, the range of the “Max Height” settings is 10m

- 100000m, the range of the “Max Radius” is the same. So that the aircraft will fly in the entered range, which is a cylinder space above the home point. For o ur applications the “Max Height” is set to 121m and “Max
Radius” set to 926m.

If spectrum approval is not required, under what regulation is the use of the frequency author ized? Command control transmitter operates at 2.4 Ghz. Video and telemetry is transmitted at 5.8 Ghz. These are industrial, scientificPage 13 , 02

- 08

- 2015

and medical (ISM) radio bands

. ISM bands are defined by the ITU

- R in 5.138, 5.150, and 5.280 of the Radio Regulations

. uses of the ISM bands are governed by Part 18 of

the FCC rules.

(b) What type of signal pr ocessing and/or link security (that is, encryption)

is employed? Data transmissions between the UAS and transmitter or ground station are not encrypted. However, during “ binding ” the transmitter sends a unique identification code, GUID, to the UAS. After the UAS is bound to the transmitter all data packets exchanged between transmitter and aircraft are validated using the GUID.

(c) What is the data link margin in terms of the overall link budget at the maximum anticipated distance from the control station? How was it determined? Our flight profile analysis and field testing results suggest a normal operating range of 10m

- 300m. Control station and video link rated to 2000m. N ormal operations provide a 85% data link margin.

(d) Is there a radio signal strength and/or health indicator or similar display to the pilot? How is the signal strength and health value determined and what are the threshold values that represent a cri tically degraded signal? The ground station computer displays the signal strength. Health of the signal strength is displayed on a 0

- 5 scale. A signal strength of 0 lasting 10 seconds or more will automatically trigger the return to home protocol. If the signal strength should drop to 0 for less then 10 seconds more than 2 time during the flight the PICs will determine if the RTH protocol is executed or to continue the flight profile.

(b) Describe the operatio nal procedures in the event of a lost link. As soon as a lost link situation is identified the PIC will make an assessment as to terminate or continue the flight profile. After the UAS enters lost link mode it will continue to attempt
to reestablish commu nication with the ground station. The PIC can choose to terminate the flight profile by allowing the UAS to execute its return to home, (RTH), protocol. While in lost link mode if the UAS reestablishes communication with the ground the PIC can chose to; a llow the RTH function to terminate the flight or disengage the RTH and continue the flight profile. While operating in class, B, C or D airspace the PIC will make contact with appropriate air traffic control agencies by two way radio and continuously

moni tor appropriate frequency. In case of lost link, the PIC will immediately notify controlling agency of the situation. While operating in class E airspace lost link situation occurs, the PIC will notify appropriate ATC agency of the situation.

( c ) Describe the sequence the UA will follow in the event control link
is lost. Lost link sequence;

(1) Aircraft will slow to a hover and level attitude. If signal is regained within 3 seconds the aircraft will continue flight path.

(2) If signal is not regained in 3 seconds fail safe is triggered and aircraft execute RTH protocol. If RTH protocol is triggered aircraft will ascend to AGL of 20 meters if current AGL is below 20 meters. if current AGL is greater then 20 meters

current altitude wil l be maintained.

(3) After aircraft AGL adjustment aircraft will follow a direct path to original takeoff location.

(4) Aircraft will hover over takeoff location for 10 seconds before auto

landing sequence begins. The 10 second delay provides an opportun ity for the PIC take control and manually land the aircraft if necessary.

(d) Describe how the aircraft will react during takeoff, climb, cruise, descent, and landing in the event of a lost link. Should a lost link occur during take off or landing the f

light will terminate. If lost link occurs during climb, cruise, or descent the return to home protocol is triggered.
