Airbuses side stick improves crew comfort and control, but is there a hidden cost?

The Airbus FBW side stick flight control has vastly improved the comfort of aircrew flying the Airbus fleet, much as the original Airbus designers predicted (Corps, 188). But the implementation also expresses the Airbus approach to flight control laws and that companies implicit assumption about the way in which humans interact with automation and each other. Here the record is more problematic.

Thinking about the unintentional and contra-indicating stall warning signal of AF 447 I was struck by the common themes between AF 447 and the Titanic. In both the design teams designed a vehicle compliant to the regulations of the day. But in both cases an implicit design assumption as to how the system would be operated was invalidated.

Why something as simple as control stick design can break an aircrew’s situational awareness

One of the less often considered aspects of situational awareness in the cockpit is the element of knowing what the ‘guy in the other seat is doing’. This is a particularly important part of cockpit error management because without a shared understanding of what someone is doing it’s kind of difficult to detect errors.

A report by the AIA on engine rotor bursts and their expected severity raises questions about the levels of damage sustained by QF 32.

It appears that the underlying certification basis for aircraft safety in the event of a intermediate power turbine rotor bursts is not supported by the rotor failure seen on QF 32.
