Calculating Headwind Component for Trigonometric Wind Triangle Problem
Reply to thread
Message
[QUOTE="Cristiano, post: 5497573, member: 570546"] This is a question about the well known trigonometric problem of the wind triangle, but my problem is just the calculation of the head wind component. I don't know how to write a general procedure to find the angle between the wind and the speed of the aircraft (the so called ground speed). Suppose that the wind direction WD= 120° and the ground track GT= 40°; the wind direction is always *from* x degrees, then I need to consider WD + 180= 300; the angle is GT - 300 + 360= 100°. Now suppose that WD= 40° and GT= 120°; the above formula doesn't work; in this case I just need to do (WD + 180) - GT. Please, could someone help me in finding a general procedure to do that? Thank you [/QUOTE]
