J.T & Denti, I have no problems with extra speed. Any extra energy will be helpful. In practise however, how will you determine that you're now 20 Kts plus if your speed indication all over the place. I presume we're talking bout a real WS here +- 20 kts, at least. I'm not talking bout LHR WS warning as per usual, those're beer shakers. I'm talking bout the once in the far east NRT, TPE, HKG or US east coast. Being within a 50 kts waring zone of a TD, let alone a typhoon you can already pretty much forget your IAS indication. How will you know you're At the point of VR+20 with speeds fluctuations of at least +- 20 kts unless you got so much runway that one can just sit it out and rotate as per arse feeling. J.T. SRS will provide a min climb rate of 300ft/m for WS conditions, if followed the FD. If the WS is so severe, we're talking downburst now, then Aplha Protection will at least keep the a/c alfoat so to speak. Not changing the config is supposed to soften the blow apart from not disturbing the air flow for better lift initialy. In thoery it sounds nice, in practise all depends.
