冷天气起飞时的高度修正研究

对飞机在冷天气起飞时是否应该对高度进行修正问题进行了研究，通过理论分析和实际计算证明：由于冬季低温天气实际温度大大低于标准大气温度，几何高度可能比气压高度低几百英尺甚至更多。因此，冷天气起飞时应该对改平高度进行修正。文中给出了冷天气高度修正的通用计算方法，并以波音公司的图表为例介绍了冷天气高度修正方法。

Cold Temperature Take-off Altitude Correction

This paper studied a problem whether or not it is necessary to calibrate the altitude value when aircraft takes off under cold weather conditions.After a series of theoretical analysis and statistic reckoning,the results show that the geometric altitude may be several hundreds of feet and even much lower than the pressure altitude because the actual air temperature is well below the standard air temperature in winter.Thus,it is important to calibrate the defined straight and level flight altitude when aircr...
