"Generally speaking, aircraft flying south, southwest, west, and northwest must be at an even altitude, like 36,000 feet. Aircraft flying north, northeast, east, and southeast must fly at an odd altitude, like 37,000 feet," says Bubb. "This enables air traffic controllers to safely spacea...
Airplanes fly at an altitude of 10,000 meters, where air temperatures can fall as low as -70℃. Despite these extreme conditions, the passenger cabin maintains a comfortable temperature and humidity. Below the passengers, the luggage compartment is usually much cooler. Separating these two sections...
to London but seven hours to travel east-west from London to NY.The reason for the difference is an atmospheric phenomenon known as the jet(喷射)stream.The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic.The planes moving at a c...
The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite. What would...

What happened would depend on how strongly the things were attached to the Earth.The Earth is moving at quite a speed,moving at over a thousand miles per hour.If you turn something around your head on a string(细绳),it goes around in a circle until you let go of the string.Then it ...
The physiological results often include cognitive impairment or light-headedness, which can seriously impair a pilot's ability to fly the plane. Pressurized cabins enable pilots, crew and passengers to avoid these pitfalls of flying at high altitude. While the air outside the cabin thins out the...
