Question

You are piloting a small plane that can maintain an air speedof 148.5 kt (knots, or nauticalmiles per hour) and you want to fly due north (azimuth = 000°)relative to the ground. (a) If a wind of 29.7 kt isblowing from the east (azimuth = 090°), calculate the heading(azimuth) you must ask your copilot to maintain.
°

(b) At that heading, what will be your ground speed?
kt

Explanation / Answer

V = 29.7 i +148.5 j. = 90- arctan(148.5/29.7) Vmag = (29.7^2 +148.5^2)
