Hi guys!After three days rumbling through the AOM, Tutorial and the intro document, i'm still totally in the dark with respect the Vapor Cycle Airconditioning system. I know i'm NOT supposed to use it above 1500 AGL, but where ios the controlpanel for it, and what does is do!?!?I've been looking through all the documents, but I just can't find it!!Help ;)Martin

Vapor Cycle is just a fancy name for freon-type of cooling, used on the ground to condition the cabin air before engines start. Once engines are up and running, you've got an "air cycle" machine to handle cooling/heating.

THX a bunch for the quick answer!I'll be sure to use it only on ground!Martin
