Why don't commercial planes fly at 45,000 ft?


Why don't commercial planes fly at 45,000 ft? Spending less on fuel is great for airlines, for obvious reasons, but a plane's engines also need oxygen in order to work, according to Traveller, to create combustion, which also creates energy. So, flying too high can also cause problems because the air is much thinner.


Can a Boeing 777 fly at 45000 feet?

It is powered by two engines and is the largest twin jet aircraft. The Boeing 777 is certified to fly as high as 43,100 feet, but typically cruises between 35,000-39,000 feet.


What altitude do military planes fly at?

Some business jets can soar up to 15,000 meters, while most military aircraft can fly at this altitude or even a little higher. However, these aircraft tend to stay below 15,000 feet for safety reasons, as the air can become too thin and make it impossible to burn aviation fuel continuously.


How high can you fly without oxygen?

For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).


How do pilots know if the plane is too heavy?

An overloaded aircraft may not be able to leave the ground, or if it does become airborne, it may exhibit unexpected and unusually poor flight characteristics. If not properly loaded, the initial indication of poor performance usually takes place during takeoff.


Why don t commercial planes fly at 45000 feet?

For starters, the engine may suffocate from a lack of oxygen. Engines work by mixing air with fuel to create combustion. The higher an airplane flies, the less air the engines will receive. Second, the airplane's wings may fail to produce a sufficient amount of lift to maintain its current and excessive altitude.


What happens if a plane flies too high?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.


Can airplanes stop in air?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.


Why don t we fly east to go from India to USA?

Because the Earth is a three-dimensional sphere and not merely a two-dimensional flat, East-West surface. Because of this spherical shape, often times the shortest distance is flying more north and south, up over the Northern latitudes and the North Pole, rather than flying east/west over the Pacific.


Can a 747 fly at 45000 feet?

For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).


What happens if a plane goes 50000 feet?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.


What can fly at 60000 feet?

Nevertheless, certain exceptional aircraft like the Concorde and the Tupolev Tu-144 have managed to ascend to altitudes of FL600 (equivalent to 60,000 feet).


Can a plane fly 100k feet?

A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it.


What do pilots see when flying?

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
