Question

4. The GPS system on your airplane has malfunctioned and so(gasp!) you’ll have to navigate by dead reckoning. What is the magnitude and direction of the air vector(airspeed and heading)you’ll need to fly if... 1) the known wind vector is 055 degrees true with a wind speed of 40 mph and 2) the displacement vector from your present position to your destination lies in a direction of 340 degrees true with a distance of 100 mi. You must land at your destination in ½hr. Notes: The directions in this problem are based on true (geographic) north with 360 degrees being north, 090 degrees east, 180 degrees south and 270 degrees west. The angle of the wind vector is given as the direction from which the wind is coming, not the direction to which it is going. (ie if the wind direction were 360 degrees, then you would feel the wind on your face if your face was pointing north. The air vector is the velocity of the plane relative to the air mass in which it is flying, the wind vector is the velocity of the air mass relative to the ground and the ground vector is the velocity of the plane relative to the ground. Write your answer in mph and degrees relative to true north clockwise​
