  3. If an airspeed of 100 mph is required for takeoff, what is the ground speed required? 75.85 mph

  4. Before the pilot is able to take off, the wind shifts. The wind is now directly out of the north at 25 mph. Will the pilot choose the same runway? Yes
    What is the ground speed required now? 78.35mph
