ARTICLE: Air France 447 Probe Raises Questions about Stall Warning Ergonomics

072512

The Bureau d’Enquetes et d’Analyses issued a final report on the AF 447 accident which analyzes the probable causes for this tragic A 330-203 in the Atlantic Ocean. The French safety bureau has asked some very important questions and, as noted in the attached article, one of the most probing and perhaps distressing issues raised by BEA involves the small motor muscle ergonomics that are part of the Airbus sidestick (see above picture). Further, the report questions whether the pilots heard the aural warnings during this high stress period of flying.

These are difficult questions to pose in that this is a unique Airbus design (Boeing uses a cross linked pilot yoke system). It will be interesting to see how the Direction Générale de l’Aviation Civile, which certificated the A220-203 and other Airbus aircraft with the same sidestick, handles this delicate airworthiness issue.
