Hey all,Can anyone tell me about the air conditioning unit, because Ive searched through all the pdfs and only found its mentioned once in a sentence in the introduction pdf.I assume it for providing air conditioning (as opposed to the air start unit). When I activate it in the CDU, my Duct pressure gauge doesnt move.So is there a procedure for using it somewhere in the docs that I cant find?Or am I misunterstanding its use? (btw, absolutely loving this aircraft) regards Andy

What do you activate in your menu? The Air Start Unit?

The ground air conditioning doesn't feed the packs or the bleed ducts. It connects directly to the cabin supply ducts. In fact, the packs are supposed to be off while ground AC is used (FCOM Vol2. page SP.2.2). Only when you use the ground starter will you have bleed duct pressure and you can also use the packs.

Aah, interesting, thank you.

Thank you, Ryan. I was wondering about this too.
