Many of the changes seem to be because of more modern wing and fuselage designs as well as safety features, like deployable chutes etc. Part 141 curriculum tries to satisfy some of the older training issues.
I am with you Klaus. I have now done a number of Tail Wheel endorsements given to newer pilots trained with much less use of unusual attitudes, no more accelerated or whip stalls, but most concerning, trained to correct a low wing (the one falling off
) during a stall with "Coordinated Aileron and Rudder". I teach strictly, Rubber to right a low wing in a stall and neutral rudder and show students what will happen in a 60 plus year old constant chord, slab wing will do when an aileron is lowered on the low wing, looking (and acting) like a big old flap and starting a rotation into that wing. Really important on my Multi-Engine Students when doing VMC demonstrations also.
Although I really do not do primary instruction any more, when I did, spins was always in the curriculum and always in an aircraft that was fun and safe to spin, rather than a C-172 that needs to be forced into one. Interesting to see how uninformed newer students are about the end results of cross controlled stalls and just taught to keep the ball centered, which is much easier to do when you know you are going to do a stall and STAY AWARE or the ball, unlike in the real world when correcting that low level base to final turn that they did not plan or execute well.
Did a few Flight Reviews the other day (no longer called Biennial Flight Reviews by the FAA) and did some of my old Unusual Attitude Training. "Close you eyes and flight straight and level" which I let them do until we are in some real unusual attitude that they never felt was coming nor could look out the side of a hood and sense what was going on. No change in engine setting or noise. Just like how I handle spatial disorientation training for Instrument Students, but I leave out the Sugary Donut and Regular Coke as well as the starless night over water, that I use for Instrument training.
