我想了解一下空中飞行时间。
斯波坎之行前三天，该飞行员的空中飞行时间为2小时32分钟。
In the three days prior to the Spokane trip, the pilot logged two hours and 32 minutes.
新加坡胜安航空公司开通的新加坡至长沙之间每周3 个航班，空中飞行时间近5小时。
Airbus A320, the Singapore-Changsha 5 hour flight of Singapore Silk Air, flies three times a week.
类似的机器也曾搭乘美国宇航局的航天飞机在太空中飞行，但无法进行时间足够长的测试来证明它们是否有效。
Similar machines have flown in space aboard NASA's shuttles, but they couldn't be tested for long enough to prove whether they were effective.
它最早的飞行时间长达83小时，而现在将尝试在空中停留了大约两个星期。
It had earlier performed flights of up to 83 hours, and will now try to stay in the air for about two weeks.
空中客车公司的声明中说，该飞机是在1990年投入使用，飞行时间已达51900小时。
An Airbus statement said the plane went into service in 1990 and had accumulated 51, 900 flight hours.
其他问题包括对飞行时间的严格限制、空中军事管制导致的飞行路线极其有限以及对进入高空的限制。很多飞机正是为高空飞行设计的。
Other issues include restrictions on flight times, extremely limited flight paths due to military control of the skies and limited access to the high altitudes for which many jets are designed.
