Many moons ago I was in Japan for a few weeks during summer. The building I was working in turned the AC to about 80 to conserve energy. However, in the loo, the heated toilet seats were still going full blast warm. Just goes to show that silly policy is not limited to the US.

True. But if you put the packs in high on the ground with the APU bleed on, you get APU high flow rate. (yes. It's a thing) AND Placing the pack switches in high turns off the left recirc fan. It's in our FM. Not as a proceedure, but as an air conditioning description. And yes, it works great.

There is nothing in our books that disallows this procedure.

The toilet seats also serve as heat exchangers for the AC, which discourages loafing in the loo.

Yup. Amazing how far a little systems knowledge goes.

Let me guess, he is also one of the heroes that waits until push time to start the APU. What a complete tool.

8. When you get to the jet turn on the APU unless the plane is already ice cold. 120 + people put out a lot of heat and will be here soon.

9. Not one degree warmer than Willis Tower!

Same crap every year. I've lost faith in 70 percent of the guys who fly airplanes.
Guppy drivers; please try and remember to reverse this when going up past FL180. Those of us in the back freeze our asses off at altitude when you don't.

FM 4.10.18 hot weather operation for at the gate. Works for taxiing as well but eng bleeds off to kill the dual bleed light.
