**Am endment to:**  **AP PENDIX D**  **HEX sUA S SYSTEM DESCRIPTION**  **sUA S Operating Overview:**  The Hex has been reviewed by the Department of Homeland Security (“DHS”) through the DHS Robotic Aircraft for Public Safety (“RAPS”) program and has an estimated 1,500 flight hours. Prioria’s Hex Flyer is a multi

- rotor, vertical take

- off and landing platform. It simplifies users’ installation and enables quick disassembling. Frame arm integrates with ESC and motor. Wi th a Pixhawk autopilot system, it ca n achieve hovering, cruising and other flight elements. Hex Flyer can be applied for aerial photography and other aero

- modeling activities. The basic airframe T810 is manufactured by Tarot

- RC, leading manufacturer of consumer and commercial grade unmanned aerial systems.The T810 airframe is used extensively in TV and film industry as an aerial video/photo platform. Prioria performs all assembly and payload integration. **Parameter Characteristic**  Wi ngspan (rotor top to rotor tip) 37 in Height 12.6 in We ig h t, with standard payload 16 lbs Wi reless Range 1 km Rate of Descent 3 m/s typical Cruise Speed 8 m/s Approach Speeds N/A Operating altitude range 175 m (limited by SW) Ma x wind 15 kts sustained, 20 kts gusting Precipitation None Flight duration 15

The sUAS can be operated in fully autonomous flight modes. Creating pre

- planned flight paths to fly in autonomous mode is as simple as clicking on the map to create a preplanned flight path. Pre

- mi ssion waypoints, landing zone p oints, and flight area dimensions can all be entered during preflight, ensuring the sUAS operates only within specified parameters. Built

- in intelligent fault hand ling allows the sUAS to detect a system fault while in the air, and to automatically respond with a set command (one such option being to fly back to a pre

- selected rally point and land). Faults that can be detected include: loss of communication, loss of GPS, and low battery levels. **Pow er**  – The Hex and its ground control station are both powered by a Lithium polymer rechargeable battery pack. A new battery has a fully charged voltage of approximately 25.1V. The Hex’s battery charge is displayed in real

-ti me on the ground control station, ensuring maximum flight duration and safety. **Launch and Recovery Procedures**  The Hex Flyer utilizes vertical takeoff and landing, commanded either via Radio Control Transmitter or Automatic operation via Data Link and Miss ion Planning Software. In radio control (“R C”) mode, PIC uses GPS, Auto, or other modes via RC hand controller to maneuver aircraft for takeoff or landing , when desired

. To utilize a utomatic operation, PIC sets GPS flight mode in RC Controller, then uploa ds flight plan to aircraft via Datalink. Once upload is complete, selecting “Auto” on the RC hand controller activates auto takeoff and flight to first waypoint in flight plan. For landing, Hex automaticallyreturns to its launch point and establishes itse lf at a predetermined altitude . Aircraft then

executes slow descent automatic landing. **Takeoff and Landing style/ty pe** – The Hex uses a vertical takeoff and landing style, commanded either via Radio Control Transmitter or Automatic operation via Data Link a nd Ground Station Software. R/C: PIC uses GPS, Attitude, or Manual modes via RC hand controller to maneuver aircraft for takeoff or landing. Automatic: PIC sets GPS flight mode in RC Controller, then uploads flight plan to aircraft via Datalink. Once uplo ad is complete, selecting “Auto” on the RC hand controller activates auto takeoff and flight to first waypoint in flight plan. For landing, Hex automatically returns to its launch point and establishes itself at a predetermined altitude. Aircraft then executes slow descent automatic landing. **Navigation Sy stem** 

– The Mission Planner Software uses Google Maps for live map imagery wh ich can also be p re - cached for offline use in the field. Wa ypoints can be created before and during flight operation creating specific locations and sequences for the aircraft. **Maintenance**

– The Hex sUAS needs very little maintenance, and operators may perform most require d maintenance in the field with the field repair kit **Command and Control Sy stems** 

- The Main Controller (MC) is the brain of the system. It communicates with the Inertial Measurement Unit (“IMU”), GPS/Compass, electronic speed controllers (“ESCs”), and RC t ransmitter to carry out autopilot functionality. The Main Controller has a USB interface for configuration and firmware updates via a PC. The IMU consists of one 3

- axis accelerometer, one 3

- axis gyroscope and a barometer. It is used for sensing the attitud e. The GPS/Compass module is for sensing the position and direction. The LED indicates different states of system. Specially designed for the Controller to convert the higher voltage of the power circuit to the lower voltage required for the receiver etc. It contains two regulated power outputs for the entire Controller system and receiver separately, a battery voltage monitor, and CAN

Bus interfaces. **Ground Control Station** Ground Station enables 3

- D Map W ay Points Editing, Flight Path Planning, Real

-time Flight State Feedback and Auto Takeoff and Landing. W orking with the autopilot system, GS not only ensures stable performance and safety of the aircraft, easy operation for the PIC, but also allows the aircraft to fly along the flight path set before or mo dified during the flight mission in the Ground Station software autonomously.

**Emergency**

**Procedures and Sy stem Failures**  Loss of Link

– The sUAS does not need constant s ignal from the GCS to continue flying. Communications outages are detected by the system and are reported to the PIC. During the communication outage, the sUAS continues on its pre

- determined flight path until a failsafe is triggered. Once a failsafe is triggered, the sUAS will perform in accordance with the failsafe conditions uploaded before launch. This is accomplished without input from the operator.
