题目内容

Compared with sea level airports, there are some differences of flying high elevation airports because Air density and aircraft engine power decreases with altitude and temperature but the approach speed increases with altitude. For example, the air density is thinner, the aircraft engine performance will be significantly reduced. On the one hand, a longer takeoff distance is needed to accelerate to Vr. On the other hand, a longer landing distance is needed to stop the aircraft.

将下列段落翻译成汉语：Bird activities are dangerous to flight safety. During takeoff or landing, the aircraft at lower levels are most likely to encounter bird ingestion or bird strike.First, bird ingestion and bird strike may cause engine problems such as engine failure, engine flameout and engine vibration. Second,bird strike may cause structural damage to the aircraft such as nose, windshields and engines.

翻译：请将下列段落翻译成汉语。A belly landing or gear-up landing is when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. Normally the term gear-up landing refers to incidents in which the pilot forgets to extend the landing gear, while belly landing refers to incidents where a mechanical malfunction prevents the pilot from extending the landing gear.
