I was on the approach the other day coming into land the tower gave me a w/v 180/10kts. I looked at the wind sock and it was more like 210 ten kts. My student says the following......
Here is my brain teaser....If the wind is given in magnetic (unlike a forecast) and the wind comes relative to TRUE NORTH (because the wind doesn't "feel" the effects of variation) and the controllers equipment makes a correction for local variation which means the windsock tells a true picture and the given w/v is different then what is going on..????
i have a handful of these types of quezzies I don't dare say this one to my colleagues for fear of intense laughter!
PS here in FAGG the variation is 25w
