I would ask that you read BEA IR #3 pp. 79 to wit:

"4.3 Recommendations relating to Flight Recorders
Analysis of the FDR parameters and audition of the CVR provide information that is essential to an understanding of the event. However, it is difficult to reconstruct the indications that were available to the crew on their instrument panel, especially the instructions given by the Flight Director crossbars when they reappear. It is also impossible to see whether there have been any attempts to re-engage the autopilot. A view of the instrument panel would complete the information provided by the FDR and the CVR and would make it possible to confirm the indications that were available to the crew and the actions that they made. Numerous recommendations have already been made on this subject over the past ten years without any real progress having been made.4.3 Recommendations relating to Flight Recorders

It is BEA who suggest there are serious problems with the indications available the pilots, as to reconstruction, availability.

Specifically, autopilot commands, attitudes and speeds. OH, and FLIGHT DIRECTOR CROSSBARS


Thought you might be interested.
