Hi RiverRock,
Well you need to know what altitude you are going to fly, then you look on the F214 to get the area winds aloft, which will be different to any METAR or TAF at the airfields you are going to visit. This wind is marked onto the Whizz-Wheel.
My guess is that unless it is CAVOK and with airspace above us, the 2000ft wind will be used. It would be nice to do a QXC at 10,000ft but this is GB.
