P. Pilcher. Methinks you have made quite a drama out of that 1.3Vs landing approach! Presumably, if you have certified the student competent to go solo, he would have previously carried out several uncomfortable landings from which he would have either re-landed by cushioning any bounce (which is the safest and most convenient method) - or carried out a normal go-around.
A bounce caused by a 65 knot late flare and an instinctive stick pull back, would be an impressive sight indeed. A bounce from a touch down speed around 45 knots should be easily rectified. And to touch down around 45 knots in a C152 means a hold off time off around 5-8 seconds from 54 knots over the fence throttle at idle. So what's the problem with 1.3Vs? Its not dangerous - it is a normal landing speed for just about every type of aircraft designed.
On the other hand a flare at 65 knots aiming to touch down just as the stall-warning beeps, necessarily means you have to dissipate 20 knots by floating. No problem with plenty of runway in front of you - but a potential hazard on a shorter airstrip than normal. And do you then add yet another 5-7 knots over the fence for a flapless? That makes it 77 knots which is damned near cruise speed on a hot day for a C152..
Seems an awfully foolish way to land a small training aircraft.
