The GFC 500 requires configuration to match the specific aircraft characteristics. This includes:
- Aircraft Weight and Balance: Input the weight and balance information into the system.
- Control Inputs: Calibrate the control inputs for pitch and roll as instructed in the manual.
3. Conduct Ground Tests
Before taking the aircraft into the air, conduct thorough ground tests:
- Engage the autopilot and verify that it responds correctly to inputs.
- Check the functionality of the control panel.
- Test the servos to ensure they are operating as expected.
Flight Testing
Once the installation and ground tests are complete, it is time to conduct flight tests to ensure everything is functioning correctly.
1. Initial Flight Test
- Perform a controlled flight test in a safe and open environment.
- Engage the autopilot and monitor its performance closely.
- Test all features, including altitude hold and coupled approaches.
2. Monitor Performance
- Observe how the autopilot interacts with the aircraft.
- Ensure there are no unusual noises or vibrations from the servos.
- Pay attention to any alerts or warnings from the system.
