I understand people's issues here. Remember the TAF always forcasts the worst case scenario for the period indicated. The METAR was 7KTS for 1 1/2 hours as i was watching it. It never went over 12KTS.
I think the FTO was being very over cautious. At the end of the day its their aircraft, but on many occassions the TAF has been wrong and updated as was the case on sunday in Manchester.
I've landed in 15KT crosswinds....it's good practice for me
