Hey IPACS,

after reaching the CRZ ALT using VNAV,
the ALT HOLD button starts to flicker.
Is this a bug?

Greetings

Thanks, this is now fixed internally and is waiting for an upcoming update.

Please try if the issue is resolved when you disable the assistance for "autopilot".

Thank you Jan for fixing this issue so quickly! It does indeed not occur when the assistance for "autopilot" is disabled as it seems - I just tested.
