Calibration – H8E

Carrier H8E

• Location: Place the drone in an open area, away from any metal objects or large structures that could interfere with the compass readings.
• Environment: Ensure the calibration area is free from electromagnetic interference, which could affect the compass accuracy.

1. Compass Calibration:

Use Mission Planner's compass calibration tool:

Steps:

1. Connect the drone to the GCS using telemetry or USB.
2. Go to the Initial Setup tab in Mission Planner.
3. Select Compass Calibration and follow the on-screen instructions.
4. Rotate the drone in all directions as indicated (pitch, yaw, and roll).
5. Save the calibration.

2. IMU Calibration:

Use Mission Planner's accelerometer calibration tool:

Steps:

1. Place the drone on a flat, level surface.
2. In Mission Planner, navigate to Initial Setup > Accelerometer Calibration.
3. Follow the on-screen prompts to position the drone in specific orientations (e.g., level, on its side, nose up/down).
4. Save the calibration.

Please always reference pre-flight & post-flight checklists for system critical calibrations:

Mission Preparation

• Mission Area Definition: Set takeoff and landing zones, configure waypoints, and verify terrain levels.
• Emergency Planning: Define emergency landing and rally points for power loss or failsafe scenarios.
• Weather and Airspace: Check for max wind speeds (>=25 MPH), review airspace, and apply for LAANC if required.
• Personnel: Station visual observers (VO) for visual line-of-sight (VLOS) and notify all personnel in the area.
• Coordination: Establish a Crew Resource Management (CRM) plan.
• Equipment Readiness: Verify all equipment is fully charged and prepare power/fuel reserves for lengthy missions.
• Final Step: Complete a Pre-Flight Checklist.

Arming and Takeoff

• Site Selection: Choose a flat area free of obstructions like tall grass or trees.
• Configuration: Verify "Loiter" flight mode before arming.
• Arming the Vehicle:

• C-GCS: Throttle down & Yaw Right.
• C-ATLAS: Left Stick Down & Right.
• HereLink: Left Stick Down & Right.

• Confirmation: Confirm "ARMED" status in the Heads-Up Display (HUD).
• Takeoff: Ease throttle up and monitor climb out.

Disarming and Landing

• Positioning: Center the vehicle over the landing area.
• Descent: Reduce throttle and descend slowly until touchdown.
• Disarming: Hold throttle down for 10 seconds until propellers stop; confirm "DISARMED" in the HUD.

Post-Flight Procedures

Order	Procedure	Post-Flight Inspection
1	Cool down EFI generator in IDLE, then STOP (EFI only).	Check propellers for chipping/delamination; apply socks.
2	Power down IE Fuel Cell (Hydrone only).	Check boom arms for damage and locking functionality.
3	Power down peripherals (cameras/LiDAR).	Check motors for debris or grate damage.
4	Power down drone by unplugging batteries.	Inspect airframe integrity.
5	Power down Ground Control Station.	Fold landing gear and store in case (Electric only).
6	Store all components in respective cases.	Align vehicle in case per page 6 diagram.
