The high pressure air door (used for huffer starts) opens down and there is no way the slip stream would latch it closed. I agree that closing it or deferring it with speed tape is what should be done. I also know what its like in a CRJ with no APU after the long taxi to 17 in the summer time. Any legal creative solutions out there? Park in the pad and have FO close it... maybe MX... ? Returning to the gate for something so easy with almost no A/C is a pain in the A$$.
