Airbus new multiple failures Landing distance
Hi folks.
something not clear to me with the latest Airbus landing distance calculation method in case of multiple failure, mainly due to the fact that it's not specified if multiple failures (now referred to as "several failures") are really multiple!
A330 exemple:
We have an ENG 1 fail, that's by airbus definition an INDIPENDENT FAILURE. the ecam leads you to shutdown the engine, that leads you to have a subsequent PRIMARY FAILURE (boxed on ecam): HYD B LOW PRESS, plus a number of secondary failures.
my question is, shall I now apply the Several failure landing distance calculation or shall i treat it like a single failure (eng fail)? any reference is appreciated
