There are questions that arose from beating the ACARS to death for two years! As to ambient noise, which is likely given "turbulences forte", ACARS "WINDSHEAR", and "do you think we have some crazy speed...?" Etc.
If due to an unusual sound of airstream, it is recorded on the Cockpit Area Microphone...
To my knowledge, few people have heard that recording, with its nuances, intonation, alerts, etc. but an easy take once heard, I should think.
Also, by 'crazy' Bonin could mean slow, fast, or sideways (slip)..... To include the turbulent airmass of cruise in the ITCZ.....
One would need experience of flight at or near Stall in high speed, actual Overspeed, and the "personality" of the airframe in jet upset.....
If Wind Shear occurred, it might help an understanding of corrupt AirData, and altitude reporting. The ingredients were present for fluctuations in performance leading to A/P quit?
Trigger a protection?
