PFD and/or ND doesn't fully load and AP won't turn on. Major problem. Would seem to be an electrical thing maybe? Air.cfg has electrics always "on" and I can't turn on external power in flight (obvs unrealistic).
Sometimes starting with the default "ready for take off at SEA" cures it but often not.
It's random and annoying and should be simple to solve but it's stumped me for a while now.
Any help appreciated!
