(one-time rapid yaw oscillation on takeoff from DXB),
Known as
pod nod and in my sixteen thousand hours on the type, have noticed this a few times, easily corrected, if the pilot knows what to do.
But my experience at RJ, the numbers quoted, the conversations I had with R-R and RJ people, are just as I related.
Intertesting.
As I work with ex-RJ guys all the time (our flight mechanics) they have mentioned no such thing, and several of these guys were sent to Lockheed and RR for training prior to RJ receiving the type.
Likewise, SV had no such problem that I recall, and I was there for over ten years, flying the airplane.
