You are piloting a small plane, and you want to reach an airport 450 km due south in 2.0 hours. A wind is blowing from the west at 75 km/h.What heading and airspeed should you choose to reach your destination in time?
Make an angle measured from S counterclockwise to heading (somewhere SE)
the Easterly component has to be 75km/hr
The resultant is S, and the heading is 450
Then TanTheta= 75/desired resultantvelocity
solve for Theta.
Your airspeed should be
solve for desired airspeed.
