Le Point article on AF 447 accident simulation
For those that are more comfortable with an English version, here are some excerpts from the article. I've selected based on elements discussed on the AF 447 threads:
- the thrust at FL 350 was at %85 - article comment: "at this altitude Thrust level changes other than Idle don't bring a very significant power variation."
- "for changing altitude, the procedure requires a pitch no less than 0 degrees for descent, or 4 degrees for ascent."
- "the altitude change caused a buzzer to sound at 200 ft above FL350."
- "95% of 4 minutes, the NU action was present. However, there were a total of 6 short ND commands."
- "at FL 375 the climb is at 700ft/min, and the plane still flies at 4 degrees attitude and 215knots, certainly slow"
- "when the Captain rejoins, the speeds are invalid, the Stall Warning stops, quite a confusion in the cockpit"
- "while the plane was at 10000ft/min descent, and 40 degree attitude (AoA), the actions of thrust to Idle, and ND don't bring a significant change, AoA remaining above 35 degrees."
