AF 447 Thread No. 12

[RetiredF4]

The hands off simulation demonstrates two points within the initial first minute of the upset:

The pitch excursion was caused by Bonins initial pitch input
The roll excursion was worsened in frequency by Bonins attempt to level the wings.

While the pitch excursion only manifested itself for Bonin in an increased pitch indication and a steady climb rate (if he noticed those), the roll excursion was changing from left to right (like wing rocking) despite the inputs Bonin made.

That's Machinbird's point, which i share. Bonin was obsessed in geting the roll under control, causing PIO by his inputs in roll direct, and thus not gave much attention to the pitch excursion.
