查询词典 on one's pins

It often happens that the parachute is too difficult, or even impossible, to extract from it's container (especially for less aggressive persons) because of too much Velcro, or deployment pins which are too long. In certain cases, if the pilot's in a spin, it's not even realistic to grab the handle of many parachute systems. After having mounted a parachute on a harness, it's vital to do a hang check to verify that the deployment handle is truly easy to grab and that the parachute can be pulled from the container with minimal effort and in any variety of pilots position and circumstances. Seems obvious, but almost no one actually does it!

而时常发生的情况是由于过多的尼龙搭扣，或者保险销过长导致备份伞很难，甚至是根本不可能从吊带里面抽出来（尤其是对于那些体力较差的飞行员）；在某些状况下，比如在螺旋当中，很多备份伞系统的备份伞手柄根本就不可能抓到；因此在安装好备份伞之后务必要做悬挂检查：将吊带吊起来，自己坐在上面模拟在各种飞行状态下是否能够轻易而迅速的抓住手柄将之抛出来；显然，没有多少人做过这个模拟。
