I totally disagree with this nonsense about minimum drag speeds and minimum flying speeds.
A good landing (tricycle) is one in which the flare begins at the right height, at the right speed (Vref) and the aircraft touches down on or within a reasonable distance of the intended touchdown point, main(s) first with no drift, followed by gentle lowering of the nosewheel. Anything else is unnecessary "flying club heroics" in airline pilot speak. The touchdown speed is irrelevant. I'm reading a book on a/c design at the moment. It says that the rule of thumb for main gear length is that is prevents a tailstrike at the AoA that produces 90% lift. A lot of spamcans give more gear clearance than that but it might explain why Vref may be higher than 1.3Vs in some cases.
The POH has Vref speeds and perf. charts. If the figures in the POH don't suit you, maybe you need another plane or more training. In the event of an accident, any heroics outside of what is recommended by the POH could lead to insurance problems if an accident occurs.
A lot of the techniques describes here may work in a taildraggers and the smaller range of aircraft but in a lot of the larger a/c with longer tails you'll be asking for trouble. Attempting some of the techniques mentioned previously in the larger high perf. a/c used in professional environment will end with " tea-no-biscuits" with the Chief Pilot. This probably explained a lot of the loss of control accidents during Approach in high performance GA aircraft flown by PPLs.
Most flight test tolerances for Vref are -0/+5KIAS.
Flying schools should students to follow the POH, the figures given there have been tested by test pilots with higher skill and experience than 99%of us. I would be very wary of any instructor who thinks he/she knows better than the aircraft designers and test pilots.
I think its safer (even though i don't approve) to teach people to come in 5kts faster that 5kts slower. Below Vref the aircraft is less stable and L/D ratio is lower, making harder to go-around.
I just wish that light A/C manufacturers could provide more Vref speeds for different weights and configurations.
