APU shutdown curiosity

[Stu Antonio 3002]

Not a real support question, more like a general curiosity: 

In the video below (mark 0:30), the power on the flight deck is more or less instantly gone once the dude hits the APU master switch. 
In the 'Labs it will still provide power until it actually spools down. 

So is this a system/version/airline/manufacturer-thing IRL, or is this just not 100% correctly modeled in the sim (which I kinda doubt)....

It depends, if apu bleed has been used it has a shutdown delay between 60-120 seconds.

if no bleed has been used it will shut down instantly.

Which - just tested it - is OF COURSE correctly modeled in the FSLabs 

(Thanks for clearing this up @Mark Visch)
