### GROUND CONTROL STATION DESCRIPTION The Phoenix UAS is operated by a single operator from a user friendly Ground Control Station (GCS), which provides operators all necessary controls and displays to safely and effectively plan and execute a mission, including controlling and monitoring the aircraft, associated payloads and data-link status. The GCS hardware consists of a laptop or handheld tablet computer running the Microsoft Windows operating system and industry-standard GCS software used for controlling and managing missions for a variety of small UAS, along with a bi-directional communications data-link. The control station can run off of batteries or other external power sources.

Ground Control Station Hardware (Left: Laptop Option, Right: Rugged Tablet Option) The GCS software provides all necessary controls and displays to safely plan and monitor mission performance and system performance in real time and provide the means for operator intervention to return home and/or land the aircraft immediately for airspace de-confliction. The GCS software provides a map view on which aircraft status is displayed at all times including location, critical performance parameters, endurance remaining, data-link status, and critical system health parameters. The pre-planned mission waypoints can be updated real-time during the mission from the map view. Aircraft location is continuously updated and displayed on the map view. Controls and displays are provided in the software to allow the operator to select the mission mode, plan and/or modify mission parameters, waypoints, takeoff, landing and rally points and lost comms parameters, arm or disarm the motor, monitor the aircraft, aircraft

ASSEMBLY: 1. Open transport case. 2. Remove left and right wings, inspect for structural damage. 3. Insert wing clip onto one of the wings, verify intact. 4. Slide the wings together, verify snug fit. 5. Extend the Pitot-static tube to the forward position. 6. Remove the fuselage, inspect for structural damage. 7. Inspect pogo-pin connectors for damage, replace if needed. 8. Attach the wings to the fuselage:
a. Insert the wing leading edge tabs into the fuselage socket. b. Retract the slide latches and press the wing down into place.
c. Push the slide latches fully aft, verify secure. 9. When ready to begin preflight, insert a fully charged battery into the fuseiage.



## DISASSEMBLY AND PACKING: 1. Reverse order the assembly steps. 2. Place the battery into one of the bays under the fuselage pocket in the transport case. 3. Place the wings into the wing pocket in the transport case: tip to tip, bottom face to bottom face. Wing trailing edges face up. 4. Place the fuselage into the fuselage pocket. Bottom side faces up.



## STORAGE The system should be stored in a dry location within the storage temperature limits listed in Section 2 of this handbook. Battery Maintenance and Storage If not used for long periods of time, air vehicle batteries should be stored at 40-50% charge capacity. Batteries should be periodically checked for remaining capacity every three months. If necessary,

8-1 Sentera, LLC Proprietary Information

### batteries in storage should be charged back to the 40-50% charge

capacity. Battery Disposal At the end of their usable life, indicated by the battery state of health, AV and GCS lithium polymer batteries should be disposed of properly. 

## TRANSPORTATION The system should be transported in its packed away configuration. The air vehicle soft case should be packed in a cardboard box before shipping. The optional system hard case can be used as a shipping container. Battery transportation Lithium batteries must be shipped in accordance with local regulations. The Phoenix batteries are lithium polymer and typically must be shipped via a ground carrier. 

## SERVICE AND MAINTENANCE Most simple repairs of "wear" items or minor damage can be done in the field using tools and spare items included in the FSK. PROPELLER REPLACEMENT Inspect both propellers for damage including chips, broken tips, or other damage prior to flight. In the case of a damaged propeller, unscrew the broken or damaged propeller by loosening the #1 Phillips screw. Install a new propeller and replace the screw. Tighten the screw so that there is light friction on the folding propeller.

s-z Sentera, LLC Proprietary InformationSPINNER REPLACEMENT

If the spinner becomes damaged, unscrew and remove the spinner cone. While holding the propeller stationary, use the wrench to remove the nut holding the collet and yoke onto the motor shaft. Replace spinner assembly and tighten collet nut as tight as possible using wrench in the FSK (factory spec is 50 in-Ib). Ensure gap between collet and motor mount is < 1116 th inch (<1.5 mm) and that the motor/propeller spins freely with no rubbing. Install the spinner cone.

It is possibfe to operate the air vehicle without a spinner cone installed, but a spinner cone should be used if possible for better performance and orotection of the propulsion system.

### MOTOR ASSEMBLY REPLACEMENT

The motor should be replaced every 75 flights or 50 flight hours whichever comes first. The motor assembly may need to be replaced sooner if it becomes damaged, will not function properly, or exhibits unusual or loud sound when activated. Remove the motor assembly by first removing the spinner cone screw and spinner cone. Next, remove the motor assembly from the fuselage by removing three screws. Before the motor can be pulled out of the fuselage ; the electronic speed control (ESC) has to be unfastened from its Velcro mount within the nose of the fuselage. Then, unplug the motor's 3 bullet connectors from the propulsion wire harness.

8-6 Sentera, LLC Proprietary InformationPlug the new motor's three bullet connectors into the propulsion wire

harness. Match the colors used on the old motor. Remove the spinner cone from the new motor assembly and install using the three screws. Reinstall the spinner cone. If the new motor spins backwards during operation then swap 2 of the 3 bullet connectors. Propulsion Harness Replacement The propulsion assembly may need to be replaced if it becomes damaged or if the air vehicle motor will not function properly. Remove the propuision harness by removing the two screws that fasten the battery interface board. Pull the board outward to expose the wiring behind it.

Disconnect the cable from the long skinny white connector. Carefully pull the propulsion harness circuit card away from the hook and loop fastener holding it to the fuselage. Remove the motor assembly from the nose of the aircraft as described previously. Disconnect the motor leads and pull the propulsion harness out of the nose back into the battery bay. Install the new propulsion harness through the opening in the battery bay, connect the cables, attach the circuit card to the hook and loop fastener, connecting the cable, and installing the two screws.
