Analyzing the importance of accurate air data and the limits of previous calibrating methods, this paper studies the theoretical basis of laser anemometry and shows its advantages for air data calibration. We build the corresponding methodologies, including calibrating methods for static pressure, airspeed, Mach number, temperature,angle of attack and angle of sideslip. We also review the relevant researches and demonstrations conducted worldwide for different kinds of aircrafts. Finally, we put forward some advice for test equipment and preview the applications of this technique, both in the fields of flight test and airline operation. This paper offers an outline for the follow-up researches.
