double_barrel to clarify: it is not always the incorrect use of the rudder that can cause the unintentional spin but likely a lack of it.
Pilot Dar as always brings knowledge and common sense to any debate. He has introduced the danger of a spiral dive as a threat. The spiral dive when uncorrected and allowed to develop can be very difficult to get out of in some aircraft particularly those non aerobatic types with a large amount of inbuilt stability. The spiral dive can be just as disorientating as a spin and the inexperienced in such things will have some difficulty in identifying one from the other. When not corrected early the speed may build rapidly to vne: the aeroplane becomes extremely stable, the controls difficult to shift, the risk of over stressing them and a possible failure may dominate the pilots mind.
The difficulty for spiral dive training is that we can take stalling and spinning to the fully developed stage but not the spiral dive recoveries, at or around the aircrafts vne, where it matters and with the apparent control lock.
