An aircraft have a speed in still air of 400 km/h. A wind is blowing from the south at 80 km/h.
The pilot wishes the aircraft to travel due east. Find the direction in which aircraft should be steered and the speed at which it will travel.
for every hour, the aircraft goes 80km. To go south to compensate, the 400SinTheta=80 on speed, or theta=.2 or Theta will be arc sin .2 S of East.
