Week 1: A02 Airspeeds

1.1.1        Types of Airspeed

The airspeed of an aircraft can be defined numerous ways depending on the measurements available and the application. Before advanced navigation systems such as GPS, where groundspeed can be found directly, pilots were required to calculate several intermediate airspeeds before true airspeed could be found. Relating true airspeed with information about wind velocity and direction would allow for the ground speed of the aircraft to be found. These intermediate airspeeds are: Continue reading
