I've noticed that when I have a strong xwind, I will keep thrust on till About 20/retard (depending on circumstances) flare, Just before touchdown de-crab with the rudder, And if need be (shoot me) maybe I check the side stick for a little bit of aileron.
Here's my problem, I have noticed that I tend to float alot with this technique. Today was a prime example, Had a xwind about 14kts gusting 20kts Brought back the thrust about 20ft flared, floated, Landed (within the touch down) For some reason I was very disappointed with the landing and started doubting myself. It felt as if I found it difficult landing in a 15kt xwind.
Maybe you are retarding the thrust too late? I've noticed some pilots (myself included if I don't think about it before flare) are a bit hesitant to retard the TL's in windy/gusty condition and do it later than they would do on a normal day. Add some extra speed to that and voila - you end up floating...
