摘要
首先分析了 Ｊ Ｊ５ 飞机中空意外进入尾旋的原因， 说明了意外尾旋的特点。其次， 估算了 Ｊ Ｊ５ 飞机中空意外尾旋各阶段的高度损失，计算了尾旋最低安全跳伞高度。重点分析了尾旋改出的机会，并指出了尾旋安全跳伞时机。最后，根据多年来 Ｊ Ｊ５ 飞机高空尾旋飞行成功的经验与体会，以及近年来中空意外尾旋改出成功率低的实际情况， 提出了几点建议， 可供飞行人员参考。
First, the causes of JJ5 airplane getting into a spin by accident in medium altitude are analyzed and the characteristic of accidental spin is discussed in this paper. Then, the altitude loss of JJ5 airplane medium altitude accidental spin in different phases is estimated and spin minimum safe parachuting altitude is calculated. In order to make the spin safety to be understood more clearly , the chance of spin recovery is emphatically analyzed and spin minimum safe parachuting altitude is also given .Finally, some suggestions are put forward based on successful experiences of JJ5 spin recovery .
