Hi wycjol,

I don't fly the 737 any more (-200) - but I seem to remember that we couldn't mix APU & Engine Bleed air. So if we used APU bleed - we had to configure Eng Bleeds Off.

Hi ggofpac,

A320 series has no restriction for TO & Landing - just select Hi Flow and limit to FL 370.
The Engine Bleed is signalled to close when the APU Bleed is signalled open.

FCOM 1.36.10 Engine Bleed:

The bleed valve is fully closed :

........

the Bleed air Monitoring Computer (BMC) in the following cases :

overtemperature; overpressure; leak; open starter valve;

APU bleed being ON.
