[SystemSafety] Understanding Air France 447

[Dewi Daniels]

The September 2013 AAIB bulletin contains a report on two unreliable air
speed events on British Airways A321s.

Some sentences that struck me in the report:

 

"The pilots commenced the procedure for 'Unreliable Speed Indication' and
turned off the Flight Directors."  (The AF 447 crew failed to perform either
of these actions).

 

"The pilots commented that company training in unreliable airspeed
indications had made the incident straightforward"

 

"The operator had identified several possible events as having a high
priority for training within its Advanced Training and Qualification Package
(ATQP), based on a Task Analysis and Training Needs Analysis of its Airbus
operation.  Unreliable airspeed was among them, and was included in one of
the Line Orientated Evaluation (LOE) scenarios conducted in 2009-10."
(Given the timing, this training need was presumably identified in direct
response to AF 447).

I've just finished reading a new Kindle book titled "Understanding Air
France 447" by Bill Palmer.  The author is an A330 training captain at Delta
Air Lines.  It's a well-balanced account, and I found his explanation of the
avionic systems on the A330 to be very illuminating.  As a training captain,
his conclusions focus on the need for improved pilot training.  I recommend
this book to anyone interested in the topic.

 

Yours,
