How to troubleshoot Aspen Avionics Autopilot System display that does not power on?
- KKayla OdonnellAug 2, 2025
If the display doesn't power on, there could be several reasons: 1. The PFD might be missing A/C power. Check the PFD circuit breaker, the PFD on/off switch on the panel, the wiring, and ensure the A/C battery voltage is above 11.5 volts. 2. The PFD might have been improperly shut down. Try switching the unit off using the “REV” button or the “SHUT DOWN” command. 3. The PFD might be missing A/C ground. Inspect the wiring to the PFD. 4. The PFD itself might be defective, requiring repair or replacement.
