For the record: When comparing time-stamp to time-received, I have assumed time stamp is minute without seconds, i.e. 2:10 covers everything between 2:10:00 and 2:10:59, rather than 'rounded to' nearest minute.

About 'gentle' and 'rapid' roll and pitch rates:

Roll axis: Regulation requires a minimum roll rate capability of 5 deg/sec at speeds above Mmo for recovery from lateral upsets. I believe the roll rates typically used when initiating routine heading changes are of similar order of magnitude. In the accident near Perpignan the A320 exhibited uncontrolled roll rates in stalls of 30 to 40 deg/sec.

Pitch axis: Typical pitch rate during takeoff rotation is 3 deg/s, in cruise probably somewhat less, say 2 - 2.5 deg/s. In the QF72 accident the airplane involuntarily pitched down at 8.5 deg/s, then pitched up in response to the pilot's control input at 5.6 deg/s.
