Default Question about the Airbus planes

While that is a possibility the timing might suggest otherwise. The
malfunction reports that reported electrical and pressurization failures
came several minutes AFTER other serious malfunction reports. It is
possible the electrical and pressurization failures report was a RESULT of
an aircraft breakup.


ACARS did not report a "pressurization failure." ACARS reported a cabin
altitude alarm. Although loss of pressurization could be one reason for
this alarm, another would be a fast descent and "catching the cabin" or
the outside altitude getting too close too fast to the cabin altitude.

Beware what you read in the press, they are taking raw data and either
misinterpreting it or trying to "simplify" it for their impression of
their reader's intelligence.

Exhibit A for this is the NY Times:

"A loss of cabin pressure could suggest a break in the fuselage, but
planes are built to withstand buffeting from a storm’s updrafts and
downdrafts. It could also be a consequence of an electrical failure, if
the plane’s air compressors stop working."

As if the A300 has electric air compressors! No western transport plane
flying today does, although the Boeing 787 will change that. Perhaps
the "reporters" should do a little fact checking and research about what
they are writing about.
