Years of accumulated experience suggest the choice of the following compromise: set structural standards for paraglider lines and hang glider hang-loops high enough to essentially exclude the pilot can separate from his paraglider or hang glider, and test emergency parachute equipment for structural integrity to roughly 150 km/h.

多年的經(jīng)驗積累給出了如下一些妥協(xié)：結(jié)構(gòu)標(biāo)準(zhǔn)考慮了飛行員可能會和滑翔傘或者懸掛滑翔機分離造成的高速下開傘的情況亚洲日本看视频，備份傘結(jié)構(gòu)測試采用的最大速度為150km/h。
