- 30

- 2015

Equipment used for direct and indirect control of Y6

- Scout are; The portable Ground Control Station, and the flight control transmitter. The ground Station (GCS) consists of five primary components: 1) a DC Power supply, 2) computer, 3) Digital Vide o Recorder (DVR), 4) In

-

flight, (FPV), video display, 5) Omni

- directional up

- link and down

- link antennas.. UAS system status, and flight telemetry are displayed and recorded on the GCS computer and DVR. The GCS contains a primary and secondary flight c ontrol transmitters. The pilot in charge maintains control of the air craft with the GCS’s primary flight control transmitter. If necessary the co

- pilot/observer can assume control, with PIC permission, of the craft via the GCS secondary flight control co mputer. Flight plans can be uploaded to the Y6

- Scout prior to completion of take

- off cycle enabling autonomous flight. When the Y6

- Scout is operated in autonomous mode the operator can alter the flight plan via the GCS computer or manually control the cra ft via the GCS primary or secondary flight control transmitter.

The Y6

- scout is equipped with a 2.4GHz flight control receiver with 3 satellite antennas. The multi antenna array limits RF interference resulting from airframe orientation during flight. Th e receiver is bound to the primary flight control transmitter. The PIC operates the primary flight control transmitter. The PIC, via the flight control transmitter, can pass/take control to/from GCS. The CGS communicates with the UAS at 2.4GHz. Using a s eparate Tx/Rx.

11. System Safety

— Flight Termination and Lost Link. Describe/explain the expectation of aircraft flight if fuel is starved. Describe/explain aircraft lost link and emergency recovery procedures. Provide an explanation of the flight termination system
in detail.

The Y6

- Scout motors are battery powered. Battery power is monitored by the GCS and provides the operator alerts as the battery becomes depleted. Status LED mounted on UAS also provides power warning status.

Loss of Communication in Flight ; Indications of lost or intermittent communications are identified by pop

- up warnings. Other indicators of weak up link are slow response to user inputs and failure to sync missions. Link signal strength is indicated on the GCS. Sustained loss of signal will activate the Return to Home autopilot.

Return to Home autopilot During the launch sequence the craft stores its present location in memory. The Return to Home autopilot instructs the craft to climb/descend to an altitude of 20m AGL then proceed on a heading to the location stored in memory. Upon returning to origin the craft will orbit over the launch point for 10 seconds then lands at the launch point. Restoring the communications at any time will allow the pilot to choose between autopilot landing and manual control.

Flight TerminationPage 9 , 04

- 30

- 2015

The Y6

- Scout does not include a flight termination system. However the operator can terminate the flight at any point by commanding an immediate power shutdown landing.

12. Command and Cont rol. Provide a description of the system and/or procedures for
command and control of the UAS or OPA.

The Y6

- scout UAS utilizes a fully autonomous flight system. Y6

- Scout UAS incorporates an advanced autopilot system with integrated GPS, which provides pr ecise navigation, station keeping and easy aircraft re

- tasking. The autopilot and embedded navigation system integrate with the intuitive and easily operated lightweight GCS that allows operators without flight experience to easily plan and execute autono mous missions. Prior to launching the Y6

- scout UAS, the planned operational mission is loaded to the UAS via data link communications. Following launch the UAS will execute the planned mission unless the ground station operator uploads a new mission, or ta kes direct control of the UAS operation via input control commands.

13. Control Stations. Provide a description of the ground/airborne stations used to
control the UAS or OPA.

The GCS consists of five primary components:1) a DC Power supply, 2) Laptop computer, 3) Digital Video Recorder (DVR), 4) In

- flight video display, 5).

1). The ground station is powered by a 11.1v lithium polymer battery.

2). The GCS laptop provides one of two control screen to support the operation and monitoring of the Y6

- Sc out UAS. This screen supports a map overlay of terrain data, depicts flight route plan information, and provides the UAS operator situation awareness of the UAS condition and flight state. The control screen also provides user controls to allow the operato r to provide command inputs to the UAS to change altitude, airspeed, and heading. The GCS application on the laptop computer utilizes the graphical user interface (GUI) including flight route planning and UAS monitors, telemetry calculations, and 2

- way communication with the aircraft, and also controls the video processor and the communications system.

3). The digital video recorder records video and flight telemetry transmitted from the UAS and supports post flight playback.

4). The in
