空速指示系统与飞机的性能和自动化水平密切相关,它不仅直接向飞行员提供空速和马赫数显示,还通过大气数据计算机向自动驾驶仪、导航系统、飞行管理系统、飞行记录系统和中央警告系统等提供所需的空速信息。因此,在大型运输类飞机试飞过程中,空速校准是一个非常重要的科目。飞机空速是通过测量出的总压和静
Airspeed indicator system is closely related to the performance and automation level of the aircraft. It not only provides airspeed airspeed and Mach number display directly to the pilot, but also provides the pilot to the autopilot, navigation system, flight management system, flight record system and central warning system through the air data computer System, etc. to provide the required airspeed information. Therefore, airspeed calibration is a very important subject during the flight test of large transport aircraft. Aircraft airspeed is measured by the total pressure and static
