今天在Mile-Hi跳了第25跳,终于拿到了United States Parachute Association (USPA)
A-license. 学Scuba diving (NAUI)的时候,教练老头特别严格,不过总的来说潜水证
的难度还是介于图书证和汽车驾照之间. 同样都是dive,skydiving那是相当相当的困难
,从AFF的七级,到solo jump,再到two-way coach jump, 从各种出舱姿势到hop & pop,
最终自己叠伞上天做check dive,每一步都是极大的挑战.
07/03第24跳做了check dive,这个算是A-license的期终考试.从AFF program毕业以后
虽然可以独自跳伞,但只能算是student status. 必须完成A-licesne c | h********r

Free fall的时候,女生一般都比男生跳的好.

发帖数: 1432 | 7 There are two distinct stages in skydiving -- free fall and canopy flight. They are completely different in sensation and skill. Usually, the most interesting part is the free fall.
Paragliding looks similar as canopy flight, but the actual canopy used is very different in design and fly-characteristics.
You can find a wind tunnel and try indoor skydiving. By this way, you enjoy the free fall without worrying about landing problems.

Try tandem first, then do AFF.
If there is a wind tunnel nearby, check it out before you do AFF.

发帖数: 1432 | 13 It's just a name. There is almost no uncomfortable sensation one usually
feel on roller coaster.
Your velocity is constant in free fall. There is no apparent acceleration.
You are pretty stable and comfortable if in correct body position.

发帖数: 3291 | 14 free fall有很强的感觉吗？
我怎么觉得游乐场的一两秒钟的自由下落让人心都紧了。而跳伞时候的自由下落反而不
很刺激。可能是离地面很高，visual上没有下落的感觉？

发帖数: 94654 | 16 空气阻力吧，造成其实没有freefall?
尤其新手玩得那个tandam dive，后边绑个教练，一开始还放个小伞增加阻力
那种牛x高手开始当蝙蝠侠，阻力就更大了

发帖数: 1432 | 18 正解阿,因为空气阻力,下落的速度是恒定的.
Free fall只是一个叫法罢了,并不是真正的自由落体(没有阻力,有恒定的加速度g).
Free fall的感觉就像大风迎面吹来,而自己爬在一个空气软床上一样.
一般稳定的belly to earth free fall速度是120mph左右,如果是wing suit,则只有
75mph左右. 和高速上开车一个样了. 这时把车窗打开,把胳膊伸出去的感觉就是free
fall时候的感觉.

发帖数: 1432 | 20 It's mostly psychological in skydiving. Relax is the key, although it's
hard to achieve.
But there is a certain moment one will feel very strong acceleration like
the roller coaster. That's the exit. I spent a lot of jumps to practice all
kinds of exit. It's another hard part of skydiving.
