This report reviews in detal the sources of error that may enter into the measurement of airspeed by pitot-static methods. Methods of flight calibration of airspeed installations are given. Special attention is given to the problem of accurate measurement of Mach number, air temperature, and true airspeed during high-speed maneuvers. This report also contains an extensive bibliography.

Of the systems investigated, a nose-boom installation was found to be most suitable for research use at transonic and low supersonic speeds because it provided the greatest sensitivity of the indicated Mach number to a unit change in true Mach number at very high subsonic speeds, and because it was least sensitive to changes in airplane normal-force coefficient. The static-pressure error of the nose-boom system was small and constant above a Mach number of 1.03 after passage of the fuselage bow shock wave over the airspeed head.
