APU in the heavy helicopter - what's the correct way to use it?

[guitarxe 10]

Got a mission to fly some cargo to a parade or something using a heavy helicopter. Haven't flown one before and the training doesn't cover it. There's a switch for the APU but I'm not sure what's the correct way to use it? Do I use it to help start the main engines and switch it off later? Do I keep it going during the flight?

I think IRL APUs overheat and fail but I'm not sure if they do in this game.

The APU gives you extra electrical power while the engines aren't running. In this game, they help you start the large turboshaft engines of the heavy helicopter.

The procedure I follow to start the heavy helicopter is:

batteries on

APU on

*engine start up procedure for one or both engines*

APU off

*engine start up procedure for remaining engine if applicable*

I believe that the APU is the alternative for the Starters in some way. It is true that the training doesn't cover the heavy chopper sufficiently but if you want to practice try the free flight.

If you want to be sure about the staring procedure press engines on automatically. In this way I believe you will be able to pinpoint the exact steps since they are are stated in written form at the bottom of the screen as they occur.
