Crosswind calculations using CR3 computer
lostinspace2011 created the topic: Crosswind calculations using CR3 computer
For cross wind calculations, should I worry about the difference between using the CR3 calculator and using trigonometry. The CR3 is great for an approximate value and I am hoping this will be good enough.
However some of my answers using the CR3 were off by a couple of knots, when compared to the trig method.
