have to disagree there, oak - you should aim to be at Vref(+) at 50' but bleed off to something like Vref-5 at touchdown.
Agree wholeheartedly. There seems to be a fear of flying at Vref. This speed has already plenty of fat built into it by certification rules. With regard to bleeding off the half HW component additive the FCTM says "approaching touch down." This statement frequently leads to a varied interpretation of "approaching touch down" Some assume it means during the flare and float.
The clue is in Supplementary Procedures (Adverse Weather) Approach and Landing where it says if ice formations are observed on the airplane surfaces, add 10 knots to VREF. This ensures maneuvering capability. There is also a Note that says "To prevent increased landing distances due to high airspeed, bleed off airspeed in excess of VREF+5 knots+gust correction when below 200 feet AGL. Maintain the gust correction to touch-down"
This statement suggests that the Boeing definition of "approaching touch-down" is when below 200 feet AGL. It does not mean after you flare.
Being on VREF at the point of flare is perfectly safe.
