The QF 72 accident illustrates the significant effects that ‘small field’ decisions can have on overall system safety.

The fallout from the QF 72 in flight accident has now reached the courts with Australian Aviation reporting that passengers and crew have taken up a joint class action against Airbus and Northrop Grumman (the manufacturer of the faulty Air Data Inertial Reference Unit).

So far as we know flight AF 447 fell out of the sky with its systems performing as their designers had specified, if not how they expected, right up-to the point that it impacted the surface of the ocean.
So how is it possible that incorrect air data could simultaneously cause upsets in aircraft functions as disparate as engine thrust management, flight law protection and traffic avoidance?

Reading the 2nd BEA interim report’s analysis of ACARS message timing can provide a further refinement of the cabin vertical speed based estimate AF 447′s terminal velocity.

Recent incidents involving Airbus aircraft have again focused attention on Airbus’ approach to cockpit automation and it’s interaction with the crew.

A cross walk of the interim investigation accident reports issued by the ATSB and BEA for the QF72 and AF447 accidents respectively shows that in both accidents the inertial reference units that are part of the onboard air data inertial reference unit (ADIRU) that exhibited anomalous behaviour also declared a failure. Why did this occur?
