Muddy theres nothin wrong with that but its a bit complicated mate when Nature is throwing huge buckets of water in your face with sudden 30 kt windshifts and lightning, and your flat out just keeping the sky and runway where they should be!
Why not just simpley hold GS while keeping an eye on IAS and be done with it? I do.
Given: (737)
Vref = 133 kts (flap 40)
rwy 36
wind 350-030/30G45
1200m TSRA
So Steady wind = 15kt additive
mean Gust = 15kt
total IAS additives = +30 kts
:. approach IAS = 163 kts (vref + 33kts)
(*737-300 max additive = +20kts and also 163kts is over the structural speed for for flap 40. :. fly flap 30 which has higher limit).
So to protect your much-desired additives (especialy in conditions like these):
* take a flap 30 vref instead (138 kts).
* mean GS expected = 123 kt @ 138 kt IAS + your gust of 15kts = 138kt
So (assuming wind stays as advertised) hold GS at 138kt reducing to 123 kt over the fence irrespective of the higher IAS (remember runway landing distances actualy used are dictated by GS on touchdown, not IAS).
* As mentioned some aircraft may require reduced flap setting if IAS additives are too structuraly high for the higher landing flap.
PS main danger is attempting a smooth touchdown which could result in a prolonged float especialy at lower flap settings and higher than normal IAS's.
