If you are landing on a short runway, This extra speed can lead to problems with inexperience if you have these conditions, and having a higher FMGC headwind entry can bring down the Magenta speed target.
Zone, if actual surface wind is higher than enterd then GS mini will increase Vapp but that doesn't increase Landing distance because the ground speed will be same as calculated before. Only thing is close thrust first and flare less. Why reduce GS mini protection by entering higher winds?
