Engines start up
Hi, recently i have reinstalled Q400 PRO into P3D5.3.
The issue i experience is that after longer period of time which i use for FMC programming and plane preparation engines do not start.
During my preparations i am on external power so batteries are not drained,
If i try to run engines just after loading the plane, or after short time of setting things then engines start up normally, if waiting time is let's say 20min, then engines spool up 19.8/30 and nothing is going on.
How to deal with this issue?
