OEBs

Question 1

OEB 57 CAB PR EXCESS CAB ALT (Applies to A330-200/-300)

Answer 1

The CAB PR EXCESS CAB ALT alert may appear to trigger incorrectly as the PRESS page will show a normal (erroneous) CAB Press indication. Ignore this erroneous CAB Press indication on the PRESS page and perform the ECAM anyway.

Question 2

OEB 55 AIR ENG 1(2) BLEED FAULT or AIR ENG 1(2) BLEED NOT CLSD (Applies to A330-900)

Answer 2

If either of the two ECAMs trigger on the -900, disregard the ECAM and run the OEB Procedure Instead
