True. hey - we are about
However, I dont teach my students to fly 75kts and then flare at 75kts from 150' or wherever...why? Because the manoeuvre you are talking about requires judgement....which they havent developed yet...
Illl bet at the threshold/50' you will be at Vat even if you start your flare from 175kts....you must be (well there abouts - depending on the 'type' of approach)...otherwise you wouldnt reach the runway in the same place at 6 inches just above the stall...
Im sure you will agree that flare height is governed by three things...sink rate, initial airspeed and target airspeed all types of landing follow that same principle - so we are entirely in agreement there..
Examining it further - to end up landing at the same place @ the same speed means that you can only vary the point you start the flare at (for a given configuration)...and whatever happens you will fairly closely be at the same speed over the threshold.
Therefore what I am saying is if you dont place yourself over the threshold @ the right height at the right speed you will get a different performance.
If you take 2 identical aircraft - one over the threshold/50' @ 75kts and one at 65kts, the one at 75kts will land deeper for the same approach type and technique if they are to both have the same touchdown speed.
eek...hope folks can follow that....dont you agree?
