飞机一般飞行的高度是多少
展开全部
一般民航机的飞行高度约为10 000公尺。 相信大家也十分欣赏在飞行时望向窗外的云海景象。通常一般的云层对飞行中的飞机影晌不大，因为在一般民航机飞行高度(通常在二、三万呎)的云层巳经十分稀薄。不过当有雷暴云团产生时，云层便发展得很高，而和雷暴相关连的坏天气，例如，闪电、雷击、积冰和冰雹等现象都对飞行有一定的危险。不过，现今的飞机设备先进，飞行人员又可以透过气象预报去了解坏天气出现的地方，从而作出准备。如有必要，飞机可以改变航道，以避开最恶劣的天气情况。所以，雷暴为航机带来的危险是可以避免的。 o/education/newsarticle/000531 飞行器在美国堪萨斯州萨莱纳机场起飞，当爬升至15240公尺高度（一般民航机高度为10668公尺），挤身在细小驾驶舱的福塞便可顺随喷射气流滑行，有如搭便车般轻松又省油。 singpao/20050222/international/678061 2007-03-23 18:27:35 补充： 英国帝国理工学院的科学家罗伯特。诺兰等人经过研究，提出了一个解决方案-- 降低民航机飞行高度。他们认为，视天气情况而定，当飞机的飞行高度从33000 英尺降低到24000-31000英尺之间时，将不会产生凝结尾迹。t7online/feature/news231002 2007-03-23 18:33:12 补充： 参考以下网址的附图：飞机飞行的高度就在「对流层」顶。ihouseedcity/~hm1203/atmosphere/air

cruising at 40
000ft isn't rare at all. In fact the majority of modern jet airliners is certified to fly above 40
000ft and it's particularly mon on long-haul operations where flying at higher altitude will achieve better fuel consumption and engine performance. For example from Sydney to Hong Kong
Cathay's A333s typically operate at the range of 35
000 to 41
000ft. With the initial altitude at 33-35
000ft
they gradually climb to 39-41
000ft at mid-way depending on the direction. Then all the way to the top of descend point. But most jet operations are constrainted below 45
000ft due to the extra-terrestrial ionising radiation issue. The only regular public trport operations of jet airliners at the altitude above 45
000ft in history were operated by Concorde due to the need of leaned air density and more stabled air to achieve supersonic performance. For the highest flight altitude achieved by manned aircraft
it's depended on how you define an aircraft. For manned vehicle laterally all spacecraft including space shuttle fly above 380km. But since their flight dynamic is achieved by the use of external booster (in the other words
rockets) at the initial flight stage (that me the launch) and being held on the orbit (i.e. level flight) by the inertial force (so no thrust) which maintains the vehicles at the Escape Speed (in plain words
the speed to get away from a pla)
it doesn't count as an aero-dynamic vehicle (in our words
airplane). The recorded manned airplane operation with the highest altitude achieved is the SpaceShip One flight on 21st June 2004
at the altitude of approximately 100km.
航程超过2小时的
民航机的飞行高度一般是11000公尺
航程在2小时以内的
大多是7500~ 10000公尺之间. 飞机发行的是大气层的最低层
称为对流层
高度约为14公里. 10000公尺等于10公里.
