Hy alex, unfortunately this is no Falcon or Bac111, since no air is coming out of the packs anymore, I really don't see how we can ventilate the airplane!
Hmmm... let me think...
Assuming the shape of the fuselage creates a depression around it because of increased airflow velocity (Bernoulli), some warm air can be sucked out of the airplane through various outflow valves, but how is fresh air entering the airplane????
