Listening in to Thames this morning with the wind gusting at 40kts I noticed that quite a few a/c were going around due to the crosswind and windshear, it seemed however that Swiss Air pilots were aborting there approaches more than any other airline , this may have just been coincidence and i realise that the rj100's are just about the biggest a/c that goes into city but i wonder if Swiss air has different minimums in cross winds to some other airlines as, the Ba rj's seemed generally to land ok and allmost all of the VLM Fokkers 50's ??! One way or another LCY is definately a challanging approach......
