Aiming at the modern aircraft adopting aerodynamic compensation airspeed system to improve the accuracy of the altimeter system, the requirements of the highly stratified plane are briefly introduced. The main error sources that cause the position error of the airspeed system are expounded and analyzed. The results show that the test data obtained can provide an important basis for the design of airspace aerodynamic compensation airspeed system and the highly stratified test flight method.
