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 of all, it analyzes the reasons why the J-J5 plane accidentally enters the tail spin and explains the characteristics of accidental spin. Secondly, the height loss of each phase of the accidental wake of J J5 aircraft was estimated, and the minimum safe parachute height of tail rotation was calculated. Focus on the analysis of the opportunity to change the tail rotation, and pointed out the safe tail parachute timing. Finally, based on the successful experience and experience of J-5s ’high-altitude tail-flight flight over the years and the fact that the success rate of hollow unexpected accidents has been changed in recent years, some suggestions are put forward for the pilots’ reference.
