it ain't a rocket science fellas. Pretty simple really. Above 400 ft GS Mini adds full head wind and below it drops to a 1/3. That's what usually causes so called hanging through till stabilized again. All the aforesaid scenarios qualify as wind-shear therefore 2 way to cope with it. Either divert or select FLAP 3 and add 15 KTS on VLS, in this case there's sufficient energy till touchdown. Having said that it's far more important to know particularities of the airdrome in terms of vulnerability to win-shear. Perfect example is HKG or NRT with excellent low wind shear warning systems in place. If they broadcast gain and loss of 20 Kts on ATIS you bet you'll get it.
