It's been awhile since I flew the 88 and 90 so I can't remember if it has a similar dilema but it seems like it did. So if you are running the APU and packs on the ground, make sure you are on APU power and not ground power.
Waves,
You are losing me here - "...

Reading this literally I think you are saying the LCA wanted guys to run the packs and external. Did you mean to say you "encouraged" guys to not run the packs while hooked up to the ground power."
I seem to remember it as the later, but its been a long time and since we had ROPEs back then, the only time I ever flew was on National Holidays. Of course I flew on every National Holiday.
