Quote PJ2 - Thrust produced by the engines for the climb is greater than that required in cruise so loss of a higher level of thrust would certainly be noticeable to the crew and the airplane would respond more firmly to the assymetric thrust
G'day
PJ, The Captain described the roll upon failure as a "snap roll" and thought that they had had a midair, both pilots grabbed the controls to roll her back, did someone say startle effect? Unfortunately accident reports are rather dry accounts and don't relate what it was like to be there, does the sim replicate anything that could be called a snap roll upon failure? The engine vibration was such that it caused the intake cowling to separate causing massive drag, hence the aircraft reaction.
