Air conditioning errors.

[Kerlix 99]

First thing, first.

 

Engine bleeds on, APU bleed off. That may go a long way to solving your issue. 

 

If you're performing a packs off T/O, remember to reconfigure your AC panel/bleeds as part of the after-takeoff checklist.

And isolation valve to auto, not closed.

Does that mean I need to set the flight altitude to 17000?

 

No, it means that the APU shouldn't be used for air conditioning.  It's used for aircon and power on the ground, to include bleed air for engine starts.  At that point, you turn it off, and let the engine bleeds take care of the aircon.

 

Sounds like you could use a run of the tutorial flight.

 

 

 

I'm curious, how did you know from that pic that I used engine bleeds off for takeoff?

 

Because, otherwise, you wouldn't have touched them.
