Default Apu inop

Why are some of you CAís out there in hot and humid temps while forcing passengers to wear masks for hours on end accepting airplanes with an inoperative APU?

Asking for a friend. #notreally

Then why donít you sit in the back of one of these hot boxes when its 85-90 degrees out, no apu , one pack on Mel or something like that .
We had to do it on a dh, it was absolutely brutal , borderline intolerable.

Yep - that's a fact. Single pack or no APU and > 80F... refuse it.

At many airlines, operations make the decisions on how miserably low the passenger experience bar will be set. Captains can reject a plane if it cannot be operated safely.

Take about 500 lbs extra fuel and then increase thrust on the right engine. It only takes about 70% N2 to deliver the maximum PSI to the PACK. The only downside is that you can't do this while you're moving. I've successfully cooled the cabin to 24 degrees using this technique. Not the most comfortable but at least a safe temperature, and better than canceling the flight by a long shot.

No APU really isn't that big of a deal. Obviously a little more work, but it is still possible to run flights safely unless the temperature outside is over 100 F.

Thatís reckless and an easy way to damage other aircraft and equipment in close proximity, not to mention zero regard for FOD prevention.

You need to crack open the books again. 70% N1 on the ground is *not cool* outside of the runup pad or something. Seriously, youíre going to damage something eventually and management will throw you under the bus for trying to make them happy. I have seen photos of a steel baggage cart flipped on its side from people doing similar stuff in a -200.
