Aero Products CR-3 Circular Wind Triangle T/S/D Computer by APR

in flight you may wish to calculate what your track made good is which is called the actual track of the aircraft and your ground speed you can do this calculation providing you have maintained a constant speed and heading from the last positive fix the calculation requires three inputs through a speed or TAS heading and actual wind for our example we're going to look at an aircraft that as of 200 knots a heading of 120 degrees magnetic and an actual wind of 170 degrees magnetic at 50 knots our first step is to set my tears or true airspeed of the aircraft now Taz is 200 knots so what we need to do is to bring that 200 knots around here above the two I'm independent as triangle the second step is to plot our wind vector on the wind disk which is this colored disc to make it easy what I suggest you do is to bring the wind direction of 170 degrees magnetic and bring it up above the TC mar
