Just a few words about this 'landing configuration'.. I have looked through my PPL course details, including the Pooleys Pilot's Work Book, and 'Landing Configuration' is not mentioned for Ex.10A Ex.10B or Ex11.
I also had an Instructor who asked for TTTT when approaching a Waypoint, which turned out he meant Transit, Turn, Trim, and Talk.
Where these terms come from I have no idea, maybe they are used in USA.
I have encountered the 'wing-flip' stall once when encountering my wake turbulence during a complete orbit, It flipped me out of the turn very quickly.
