And since bleed 1 only supply pack 1, and bleed 2 is still off because the 2nd engine hasn't been started, it could get quite hot in the back since pack 2 doesn't get any air.
My question is is there any operator that modified the SETO procedure by letting the APU bleed on or open the crossbleed? Is there any effect of turning those on/open during SETO?
Thanks
Use common sense. If a single pack can’t sufficiently cool the cabin, open the crossbleed, or leave the APU running.
