Hetfield - for one who has been 'flying so long' I am amazed!
Firstly your page ref is wrong - it is 20 not 24. A quick look at the paragraph
above your quote shows EXACTLY what I said in my first post:
"Given a generally smooth land surface area, when the wind blows strong and the weather is stormy, the most powerful gusts blow in the same direction as the wind above the boundary layer.
In the northern hemisphere the wind veers clockwise about 10° to 20° with respect to the mean wind direction."
What is the problem? Oh, and how do you get a tailwind out of 270/10-20 on Runway 27?. This is why 'trolls' were mentioned by OCAS and explains my reply
