If students are taught right from go to use the rudder properly to maintain balance, particularly in a go around; and the nonsense about picking up a dropping wing with full opposite rudder was taken out of the text books then we are about as safe as we can be.
So true. Even in normally benign stalling aircraft, a go-around at the flare or after a bounce or series of bounces, requires instant rudder to prevent the yaw that occurs with full power an speeds close to the stall. It seems to me instructors rarely demonstrate this manoeuvre at the flare and if they do, they tend not to accent the vital importance of countering the yaw that is inevitable. Most practice go-arounds in light training aircraft are conducted at 200 feet when there is ample speed usually in excess of flight manual threshold speed. The yaw is sometimes less noticeable
If for perceived flight safety reasons, or even under confidence of their own ability, instructors avoid demonstrating go around practice after the flare, there is no reason the manoeuvre cannot be conducted in the training area using (say) 1000 ft agl as simulated runway level. It is also important the student be taught the recommended go-around procedure found in the manufacture's POH and not an instructor's personal opinion.
It is failure to contain the yaw that occurs when high power is applied at low airspeed coupled with a nose attitude higher than optimum, that can lead to a wing drop into an incipient spin. A student needs several practices at go-arounds at the flare before he is deemed fully competent and this is why it is better done at a simulated runway altitude rather than wasting time on repetitive circuits just to get in a low go-around in crowded circuit area. It is also useful to conduct the practice under the hood (at safe altitude) in case of a night go-around at the flare or sudden onset of heavy rain obscuring the windshield
Grade 3 instructors should be required to demonstrate competency at low level go arounds on their instructor course. There is a big handling difference between a 200 ft go around and a go around off a severe bounce.
