Clearly there is no mention of "picking up the wing with rudder" in DCA Publication 45 published in 1975. So where did this expression originate? Maybe around a local aero club bar in those far back days
Perhaps an explanation lies here
Centaurus. Just been reading a pilot report on a DH 9 and the author (Roger Bailey, chief pilot of the Shuttleworth Trust, CV here
https://www.shuttleworth.org/news/er...lebrowntrophy/) has this to say,
Stalling - In all cases roll and yaw control could be controlled with unreversed use of controls up to the stall. On those occasions when a wing dropped it was not always possible to prevent the roll off with roll control alone, but intuitive use of rudder was always effective in checking the roll.
The differences between this aircraft and one designed to a post WWII airworthiness specification, it should be noted the lateral and directional characteristics of the aircraft, which are typical of most aircraft of this era, in particular of de Havilland designs, are not conventional by 'modern' standards. The pilot must understand that the primary turn control in those days was seen as the rudder, with ailerons being used only to maintain wings level or to 'fine tune' the bank angle required to achieve balanced flight. When such a control strategy is used it eliminates adverse yaw, because the rudder produces proverse yaw before the aileron is deflected significantly.However, a 'modern' pilot, one trained after WWII, expecting to enter and exit turns using the aileron to effect the roll angle change will experience significant adverse yaw unless attention is paid to balance and the rudder used generously. It should be recognised that the lateral/directional stability and control characteristics described are little different to and no worse than those of the DH82 Tiger Moth.
Since all Commonwealth pilots of WWII vintage trained on the Tiger might the 'pick up wing with rudder' emanate from those days? I was given the advice early 60's somewhere around the traps, may have been when doing the Tiger check out, don't recall.
