Thank you for your response.
FR24 began in 2009, so there was nothing available from AF447 at the time, but we did use the ACARS messages to read the tea leaves in the AF447 accident and got quite a bit from that source until the recorders were located two years later. But until we had the side-stick parameters, the stall-warning parameter plus pitch/roll, it was not possible to say where the problem originated and why; from the AF447 thread in Tech Log on ACARS:
AF447
Data is not opinion, nor is validated data stochastic. That's really my only argument. There can be a form of equivalence between FR24 information and the eventual results from the recorders but the former cannot be turned into action nor legitmately be included as part of any final report / recommendations.
