Util Pressure button/light not illuminating

[Lber657]

I'm going through the CH-47 training missions. In the first mission, it is impossible to go further than starting up the APU. The Util pressure light should illuminate, then turn off once the APU is running. It doesn't come on in the first place, so that's as far as you can go in the training mission.

You can simply ignore it and continue the mission.
