I wish to suggest that on AFE APU start, the AFE turns on the bleed air after APU startup. Perhaps also set the bleed and pack switches to provide air conditioning to the cabin, as well as set APU gen field, breakers and bus ties.

Currently from what I have seen, this AFE function merely turns on the APU. Unless I’m missing something, following solely the AFE through to engine start results in zero pneumatic pressure for the start unless additional manual setup is done to ensure the isolation valves and pack switches are set.

I will pass this along to the team, thank you 🙂
