If you have time and patience to help me with some questions that, as you also said, were not clarified during my training, actually because I haven't know about them then.
Regarding "my first question, headwind shifts to tailwind, you said 15 kts and sincerely I don't get it why it's so". I figure out that if the headwind will decrease suddenly, there should be a change in airspeed, e.g. 15kts headind changes to 5 kts headwind, if it's suddenly, the airspeed decreases 10 kts. "So, why when it suddenly shifts from 15kts to 15 kts tailwind there is no a 30 kts drop?"
Also, what is not clear to me is the difference between a wingdrop and an incipient spin. I figure out that you may have a wingdrop even if you are coordinated, because the wingdrop may be induced by engine power effects and other factors, not necessary yaw, so, with ball centered you may have a wingdrop, but not a spin, right?
If that wingdrop is abrupt, what be will be the outcome? The wing will tuck under and the result will be a spiral with nose pointing down?
During a coordinated turn descent, I know that the AOA of the inside wing is higher than of the outside, in this case, you may have a spin even if you had ball centered?
And during decrabbing, when you introduce pro-spin controls, i.e. rudder to decrab and opposite aileron just to prevent banking in the direction of the rudder, why there is no wingdrop? Considering a stall landing, the airplane is very close to stall when we introduce these controls.
