hot airplanes

[John Pennekamp]

Just curious don't most 121 aircraft even if they dont' have a APU or it is inop have A/C once you start the engines and get the bleeds going? Or is this in a smaller t-prop that is'nt pressurized?

Thanks

This is mostly a problem with the CRJ-200. The engines don't produce enough air flow at low power settings, so you don't get any cooling until takeoff with no APU. They fixed it on the CRJ-700.

But yes, most airliners don't have this problem.
