So, now you are sitting in the cockpit with a plane load of people. You have called zone once/twice to have the air pulled but it is still connected. External air is insufficient. Cabin temps while you are on the aircraft have risen to the mid to high 80's as you wait to run apu air. Your cabin is essentially heat soaked and you have 20 minutes to departure.

Would care like to expand on "exactly" as to what your next step, if any would be?
