| 摘 要： | 针对一起由静压孔堵塞造成的空难事故，对飞机全静压系统静压孔堵塞后，座舱仪表显示的空速九进行了分析，讨论了静压孔堵后仪表显示和马赫数的特点，给忆堵塞后不准确的座舱仪表显示数值估算起初空速和马赫数的近似公式，以及判断静压孔堵塞的方法和静压孔堵塞后应采取的措施，可供飞行训练部门和飞行人员参考。

| Abstract: | After pitot static vents of total static pressure system are covered, the real airspeed, Mach number and pressure altitude are not displayed from cockpit instrument, and the accident might happen. In this article, instrument display of calibrate airspeed and Mach number with pitot static vents covered is discussed. The approximate formulas of calibrate airspeed and Mach number by using radio height and instrument display figures, which are not accurate, are developed. The method of judging whether pitot static vents are covered and the relevant measurements are suggested,which can be used in pilots training. |
