BMC failure
If one BMC fails, the adjacent BMC takes over the monitoring of the bleed system to
issue the following ECAM warnings if necessary:
– Overpressure.
– Overtemperature.
– Wing leak.
Nevertheless, the associated bleed FAULT light on the AIR COND panel is lost, and the
associated bleed valve does not close automatically.
ENG BLEED LEAK warning is lost for the associated engine, as is also the APU BLEED
LEAK warning if BMC1 has failed.
