Is this true for the Airbus? Most of the turboprops I have flown used 1/3 headwind OR full gust up to maximum 15 kts.
Most jets I have flown used 1/2 headwind component AND full gust up to maximum 20 kts.
Edit:
Seems you are correct, 1/3 headwind without gust, guess the groundspeed mini calculation corrects for anything above? On the 737 there was a difference between A/T on or off for approach, with A/T on Vref + 5 was used as the A/T logic automatically corrects for any gusts, guess its somewhat the same here.
