Re: Crosswind application(s)
ToPocHi, I think that you are making meal of this! I also believe that whilst formulae may be used, they rarely are. The Mark I Human Being (the type that flies planes for a living), when doing "square" (boring?) circuits, merely places the aircraft on the extended centreline, nose a bit into the wind (a guessed heading). Then they wait and see what happens to the track made good and make adjustments as appropriate. No maths, no formulae, just common sense!
