Why are so many of you discussing GS mini when GS mini is not really relevant in the question asked?
There is no GS-mini protection for a crosswind, GS-mini only looks at the headwind component, GS mini is irrelevant in this.
What is relevant in answering the question is that the FCTM recommends to add a few knots in a gusty crosswind situation. Again, nothing to do with GS-mini.
Wether or not I would pull selected speed to add this increment to Vapp to assist in a last minute gusty crosswind scenario is a whole other debate which I will stay away from, as it’s too much dependent on company culture and SOP.
