Flying into airfield "B" also on a gusty day, with a 15 kt tailwind at 1000', which rapidly turns into a 10 kt headwind at 400'. Aircraft records a momentary speed fluctuation of up to VAPP +25 before it settles down again. Still touches down at VAPP.
Company does nothing to pilot "A", and kicks ass of pilot "B" because a speed variation of +25 was observed on short final.
Question is then, is one an unstable approach and not the other? Should pilot "B" go around and not pilot "A"? From a P of F point of view, isn't it more dangerous to be flying into the decreasing headwind than the increasing headwind?
well our Airbus FCOM stated stable as TARGET +10 (magenta bug as positioned by GS mini) and VREF -5
