This might be a know issue.
Screens go black when flying: There are multiple root causes being investigated.
Try some of these workarounds to see if it fixes it:
- Flip the ENG switches off prior to starting a flight. This only applies to the piston aircraft (e.g. C172, DA40).
- Unbind the “Set Starter” from the ENG 1 switch
- Unplug the TCA Airbus Quadrant
