Question

An airplane with a speed of 160 knots is headed east while a 24-knot wind is blowing from 240°. Explain how you would use the result of finding the ground speed to find the course of the airplane.

Answer 1

vertical speed of 20.78 knots

new course is (-148 , 20.78) = inverse tan ( 20.78 / -148) = 172° or 8° N of East at 149.45 knots

New speed (- 148)² + ( 20.28)² = 149.45 knots round and you get 181.2
