Second issue:
The ground air in the latest update is a very nice addition. However, the ground air stop flowing if the packs are shut (at least the air sound, I forgot to check in the actual airflow is linked as well). In real life the ground air doesn't need the packs to be open to flow, selecting either packs open or close should not make any difference in the ground air flow. Actually, on some airliners, selecting ground air as well as apu bleed air simultaneously will blow some hoses as the addition of both air pressure is beyond what the system can cope with (something we have to be careful with as most of the time our ground crew doesn't tell us when they are connecting ground air, and we have once in a while a grounded aircraft due to a hose that blow out of its fittings, not talking about the F100 though).
