At cruising altitude most airplanes are at between 35,000 and 41,000 feet. However, to get there it has to pass all of the intervening feet between that and the altitude of the airport.
12 feet
the answer is 300 to 600 feet
An Airbus 319 can climb to 37,000 feet in 23 minutes, and obtain optimum cruise performance between 39,000 and 41,000 feet.
Yes, many aircraft can fly in the stratosphere.
Can you fly on airplane with pericarditis
An airplane that will fly straight past 97.2 ft is the Boeing 747. It routinely flies at altitudes in excess of 30,000 feet as it travels several thousand miles at a time.
your question is why Airplane don't fly over tibet than answer is most airlines avoid flying directly over the Himalayas. this is often because "the Himalayas have mountains above 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet." Read full article on why airplane don't fly over tibet than you can check
10 kilometers (about 32,808 feet).
It depends upon the airplane and the intentions of the pilot. General aviation aircraft may fly anywhere between 500 feet and 20,000 feet or beyond. A little Piper Cub on a sightseeing trip may fly quite low, while a more complex airplane on a cross-country trip may fly at higher altitudes for better cruise efficiency and terrain avoidance. Airliners typically fly around 30,000 - 45,000 feet which puts them above most of the weather and it's also where the turbofan engines operate efficiently. Military plans may operate higher, such as the Stealth Bomber which may fly as high as 50,000 feet, or the U2 spy plane which operated as high as 90,000 feet.
Most aircraft fly in the 'Troposphere' which exist up to approximately 55,000 feet. After that is the' stratosphere' which only a few military aircraft fly in.
Neither of the Wright brothers was the first man to fly an airplane. -Many men had flown, but for shorter distances, before they did.
