Several concerns come to mind.
(a) there has long been a disjoint betwixt certification and operations. After a few serious prangs, this starts to get fixed in this area and that - eg the rudder/manoeuvring nonsense which led to the loss of AA 587 and a subsequent major overhaul in training emphasis
(b) for normal category, certification stall requirements have varied over the years but, in the basics, are done relatively sedately with a reasonably prompt recovery. Generally, power is not restored until after the aircraft is well and truly unstalled and speed is increasing nicely. I recall a flight test tale relating to TP training on a B58. Evidently, the military student thought to hold the aircraft into the stall to see what might transpire .. which was a somewhat surprising and eyebrow raising flick into an inverted spin. The certification looked at a prompt recovery from the initial evidence of the stall.
(c) for normal category, use of rudder in the stall generally emphasises the prevention of further yawing motion. Picking up wings with significant rudder application is operational pipedream nonsense tending to stupidity. How do you spell "spin", again ?
If a Regulator requires exposure to spin training (to whatever extent), then the flying schools really should be using an aerobatic aircraft for those sequences to provide some buffer for manipulative incompetence in the training sequences. This writer cannot understand the rationale behind the present absence of elementary spin training to save a few nickels and dimes in the overall scheme of things.
Sure, we have all been able to get away with this and that ... however, after a lot of such events, fatigue might just have progressed to the stage where the next pilot gets a very unpleasant and fatal surprise ?
Perhaps demonstrating the ability to
Perhaps, first, one should delve into the relevant TCDS, design regs and ACs to get an idea of what the certification might have looked at .. go too far beyond that envelope in ignorance or stupidity and you are signing up to the untrained TP brigade and get what those folk often get ..
