It is rare for airliners to fly that high, the general range is 35-40k feet. The reason they fly this high is because the air is less dense (pressure is lower) this allows the aircraft to travel faster and with less drag, thus increasing fuel efficiency.

How far from the ground is an aeroplane when flying?

It varies upon aircraft type, private or commercial flight, and where the aircraft is going and on what heading. Above 3000 ft in the UK and 10,000 ft in America aircraft will fly on what is called a flight level which works off a pressure measurement of 1013.2hps keeping a 500ft gap between other aircraft on different headings (the quadrontal rule or semicircular rule if very high). The small aircraft you see flying about will tend to be about 1000-3000 ft and helicopters tend to fly on 1000 ft. Large passenger aircraft may go to 55000 feet or higher. Small private aircraft typically fly in the lower altitudes, say 3000 to 17000 feet and high performance private aircraft 18000 to 25000 feet. Commercial aircraft fly in the 35000 to 40000 foot range, and small business jets can operate in the 45000 to 50000 feet. These are broad generalities as operating altitudes are selected on a day to day basis depending on various factors such as winds, weather, time requirements, etc. Many military aircraft have much higher capabilities depending on the specific mission.

What level do most airplanes fly?

Commercial, jet engined aircraft, such as the 747, fly at approximately 40 000 feet. Propeller aircraft fly at lower altitudes


Why do most airplanes travel in stratosphere?

Most aircraft do not travel in the stratosphere. Some military and passenger jets fly in the stratosphere, but most aircraft fly in the troposphere, below the stratosphere.


Can a passenger plane fly 55000 feet above high winds?

Passenger planes can't fly at 55,000 feet. Gulfstream business jets can fly 51,000 feet altitude, and airliners like to cruise at 35,000 feet. Some military planes, like the U-2, can fly at 55,000 feet or greater.


How high do military jets fly?

Military aircrafts fly the same height as the commercial airplanes do. The cruising altitude maybe 30000 feet to 45000 feet. Planes like SR-71 have gone upto the maximum of 85,000 feet.


Why are airplaines pressurized?

Because the pilots, staff and passengers would pass out from lack of oxygen at the altitudes that aircraft fly best. Aircraft cabins are usually pressurized to 8,000 feet altitude equivalent. This also reduces passenger inner-ear discomfort.
