I'm reminded of video of a TU-154 Dutch rolling. I'd always thought Dutch roll was characteristic of swept wing aircraft at speed and altitude; I remember Brian Trubshaw (or Roland Beamont) describing switching off the yaw damper in the cruise in a VC10 and the phugoid soon taking it to nearly 90% of bank.
Would a B744 Dutch roll to this extent in T/O configuration if for some reason its yaw dampers (if it has them) were inactive?
It does not looks like a Dutch Roll. The roll seems controled. Machinbird explained the method used after sudden pitch up (post #95).
