就在F-16C型喷气式战机机头朝下、以每分钟8400英尺（42.5米/秒）的速度呼啸着向地面冲去的时刻，特技飞行员克里斯·斯特里克林猛然意识到：表演无法完成！恐怖的时刻到了……（注：事后事故调查表明，他错把飞机显示的海拔高度当成飞机与地面之间的实际距离——可地面本身还有将近200米的海拔高度！
Pointed nose-down and hurtling toward the ground at 8, 400 feet per minute, F-16C fighter jet pilot Chris Stricklin came to a terrible realization: I'm not going to make it.
但今天的试飞表现证明了这架飞机不仅能够飞得起来，而且可以在基本飞行试验的高度上续航相当长的时间。
Today's flight demonstrates that the airplane can not only fly, it can do so for an extended period at altitudes high enough for basic flight testing.
与在高空飞行的飞机不同，直升机不容易被雷达发现，因为它的飞行高度较低，且常常被地形所隐藏，因此最大的问题是噪音。
Unlike high altitude aircraft, helicopters aren't so vulnerable to being seen by radar, as they fly low and are often hidden by the terrain. The big issue is the sound.
在1960和1970年代，大部分个人和企业的飞机是飞行高度低于喷气式飞机的螺旋桨式或涡轮螺旋桨式飞机。
In the 1960s and 1970s, most personal and corporate planes were propeller or turbo-prop aircraft, which fly at a lower altitude than jetliners.
这种螺旋桨通常装在飞行员后面的一个桅杆上，起飞的时候升起（或在帮飞机实现更高的高度或航程的时候），随后收入机身。
The propeller is usually mounted on a mast behind the pilot and raised for take-off (or to gain more height or distance once airborne) and then lowered back inside the fuselage.
如果我们把“太空”定义为较低的地球轨道，比如大概距地面高度160至350公里航天飞机飞行的轨道，有两点可以揭穿长城传言。
If we take "space" to mean a low Earth orbit such as the one traveled by the space Shuttle roughly 160 to 350 miles above Earth, the Great Wall claim fails twice.
NTSB称，西北航空公司188航班的空客A320飞机正从圣地亚哥飞往明尼阿波利斯，于当地时间下午7时与航管失去无线电联络，当时飞机的飞行高度为37 000英尺。
The NTSB said Northwest flight 188, an Airbus A320, was flying from San Diego to Minneapolis and lost radio contact with controllers just before 7 pm local time when it was at 37, 000 feet.
在联邦航空局的准则里有，像安德森先生和他的客户们娱乐飞行，必须使无人机在400英尺以下高度飞行，远离其它飞机而且在操纵者的视线之内飞行。
Under F. A. A. guidelines, recreational fliers like Mr. Anderson and his customers must keep unmanned aircraft lower than 400 feet, away from other aircraft and within the operator's sight.
飞行操纵系统的监控和冗余、飞机传感器、动力和液压的产生，这些构成了高度有效性的电传操纵。
Monitoring and redundancy within the flight control system, aircraft sensors, power and hydraulic generation ensure a high degree of availability of the electrical control.
飞机飞行的高度是这么的高，以致于我们几乎看不到它。
The aircraft was flying at such a high altitude that we could hardly see it.
飞机以接近海平面的机场高度开始飞行、爬升、巡航、下降和接近海平面的机场着陆。
The airplane starts its flight at an airport altitude near sea level, ascends, cruises, and descends to a landing airport near sea level.
飞机飞行的高度是多少？
新发动机将使ChinookMk 3飞机快速部署到阿富汗，并实现其在苛刻，高温和高度的飞行条件下的高可靠性。
The new engines will enable the Chinook Mk3 to be quickly deployed to Afghanistan, and to operate more reliably in its harsh, hot and high flying conditions.

Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops.
爬升，飞机高度不断增加的飞行阶段。
在这个高度，听着，在保持这个速度，整个飞机空着的情况下，那飞行员说还剩六到七个小时的燃油。
And at this altitude, listen, and at this speed, with the plane empty, the pilot says there are six or maybe seven hours of fuel left.
在这个高度，听着，在保持这个速度，整个飞机空着的情况下，那飞行员说还剩六到七个小时的燃油。
And at this altitude, listen, and at this speed, with the plane empty, the pilot says there are six or maybe seven hours of fuel left.
