I have seen quite a few people make Vref corrections for head wind. I do not understand why as it is totally unnecessary. You completely mess up your landing figures and you are carrying too much energy and just float when you should be on the runway and require the brakes to absorb more energy. In my view it is unsafe practice.
20 to 30 years ago most CFIT incidents were aircraft hitting the ground in the undershoot because of poor and unsafe practice. The result is that we now have a generation of pilots who think it is safe to approach high and fast. With out accurate figures to hand, now somewhere around 98% of CFIT are runway overruns.
It is best practice to come over the threshold at Vref with corrections for gusts only. This is by far the safest way to fly.
