Maintenance Query

What controls are in the Game to force the completion of A, B. D checks etc?

I think when the timer gets to 0 for a check they plane won’t fly any more until you get that check

I believe atm it is -72 hours and it will force the check if you keep delaying it manually. If you do not once it detects it goes below 0 when it is scheduling it will do the check, but that means you can still end up quite some hours into the negatives.
