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.

Question: Explain how you would use the result of finding the ground speed to find the course of the airplane.

Answer: 181.2

Explanation: 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
