Stalling
Flight Training News Pg 13 discusses an accident involving a student and his instructor whereby he was teaching stall recovery and unfortunately didn't recover from a spin.
The AAIB have made a safety recommendation that 'oscillatory stalling' is not included in any flight exercises during flight training.
Oscillatory stalling is described as 'holding the aircraft in the stall using maintained back pressure on the control column when leads to a nodding motion or 'oscillating' pitching movement. With appropriate rudder inputs to control any wing drop this could lead to a spin.
My question is this:
Flight exercises on stalling include entries, symptoms and characteristics of being stalled. In a PA28, the nose nod or 'oscillatory pitching movement' is a symptom of the stall.
In order for students to experience how this feels and therefore be able to recover, I also allow students to enter a stall and hold a stall with maintained back pressure before they recover, keeping the aircraft in balance with light inputs to the rudder and alierons kept neutral. Flight Training News also appear to have spoken to a number of instructors where this practise is regarded as common place.
Are the AAIB saying that holding an aircraft in a deep stall for students to experience its effects and subsequent recovery should be stopped as it is not safe practise due to being close to the ingredients of a spin ?
At what stage approaching the stall do you therefore allow a student to recover ? Incipient or actually stalled ?
I would be interested in other instructors thoughts !!
