Interesting discussion. The Airbus FBW and Boeing Vapp logic work in opposite directions in varying winds; With an increased HW gust, Airbus will increase thrust and IAS, (to maintain ground speed), Boeing will decrease thrust and IAS, (to maintain airspeed).
So given a gust, the Airbus will maintain its "place" on approach; whereas the Boeing will "move back" with a HW gust and "forwards" for a TW gust.
Always nervous when folk talk about overriding Airbus GS Mini, which could reduce safety margin in the event of an unexpected gust or wind drop. Some think the Airbus does the wrong thing or gets "out of phase", because it increases thrust and IAS with increased HW gust, (and vice versa). which is the opposite way round to "conventional" aircraft
