Preparing for Flight

Before launching the drone and activating the QuadroFleet module, you must perform the following pre-flight procedures.
These steps are essential for safety, stability, and reliable communication.

1. Physical Inspection

• Check the drone frame, propellers, motors, and wiring for visible damage.
• Ensure all screws and connectors are secure.
• Verify that the battery is fully charged and properly mounted.

2. Firmware and Configuration Check

• Make sure the flight controller is flashed with the correct version of iNav.
• Confirm that all sensors (accelerometer, barometer, magnetometer, GPS) are calibrated.
• Verify that the correct mixer, board layout, and receiver type are selected.

3. Channel Mapping and Failsafes

• Confirm correct channel mapping.
• Test all control inputs (pitch, roll, yaw, throttle, arming switch, mode switch).
• Configure and verify failsafe behavior — especially return-to-home (RTH) or disarm on signal loss.

4. QuadroFleet Module Initialization

• Power on the drone.
• Ensure it has a stable connection to the control application.
• Verify that telemetry and video stream are functional.

5. Compass and GPS Lock

• Wait for a valid GPS lock (at least 6–8 satellites recommended).
• Ensure the compass heading is correct and there are no magnetic interference warnings.

6. Arming Test

• Test the arming and disarming procedure.
• Make sure the drone does not arm unless all safety conditions are met (e.g., GPS lock, throttle low, level orientation).

7. Environment Assessment

• Check weather conditions, wind, and lighting.
• Ensure a clear takeoff and landing zone free of people and obstacles.
• Avoid strong magnetic fields, large metal objects, and sources of radio interference.

Once all checks are complete, the system is ready for takeoff.
