Big Pistons Forever, CASA is clearly addressing this issue and I agree with your summary in the other thread. The incipient spin is not being fully addressed in the UK. An increasing number of UK instructors have minimal spinning experience, don't like it, and appear to believe: an incipient spin is at the wing drop although this is no more than a development of the (advanced) stall. An incipient spin can only be when a rotation has begun. The ICAO type certification requirements: all controls remaining effective throughout the first rotation, mean that the standard stall recovery technique will be effective during the early onset of the incipient stage of the spin. Therefore during the early stages the spin can be broken, as for stall recovery, by pitching with a coordinated use of the rudder and aileron of course.
The majority of training aircraft available nowadays are prohibited from intentional spinning. I have never seen an exemption to allow incipient spins. If the manual states: "No intentional spins" then it must be correct that the instructor draws the line at the wing drop and goes no further but this should not infer that this can be considered an incipient spin.
