Calibration of the airspeed indicator is important for accurate measurement of flight speed. This chapter introduces the various types of airspeeds, including indicated, calibrated, equivalent, and true airspeed. Various error sources are discussed, with a particular emphasis on position error, which dominates the difference between indicated and calibrated airspeeds. Position error, resulting from an inaccuracy in measurement of freestream static pressure, is shown to affect both the airspeed and altitude measurements on an aircraft. Flight testing methods for calibrating for position error are introduced, with an emphasis on global positioning system (GPS)‐derived measurements of ground speed over three separate headings in order to find true airspeed as well as wind speed in flight.
