Why don't airliners fly higher?


Why don't airliners fly higher? 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 planes fly at 40 000 feet?

Therefore, routes are often broken up using smaller aircraft along the way. Altogether, commercial airliners have the physical capability to travel up to 43,000 feet.


How high can military planes fly?

The speed record is also held by an SR-71, at 2,193 mph. This is not as high or as fast as the airplane can fly, however, it's absolute speed and altitude limits are classified. Most US military aircraft can exceed 50,000 feet, if they really really try. Again, the limits are classified.


Why do commercial planes not fly higher?

Much thinner air means that the engines cannot produce enough trust, and the wings would not produce sufficient lift. There could also be problems restarting a failed engine at a higher altitude in the event of a failure, as well as other safety implications of flying at higher altitudes for passengers and crew.


Can planes fly at 50 000 feet?

The highest certified altitude of an airliner was Concorde's 60,000 feet. Today some of the corporate jets can fly at 51,000 feet. Q: What is the highest cruising altitude allowed? A: Most airliners are limited to 45,000 feet or less.


Why are commercial planes flying so low?

Aircraft have to fly low in order to properly line up with the runways and execute safe landings. Aircraft may, however, appear to be lower than they actually are because their large sizes make them look closer.


Why do planes cruise at 36 000 feet?

A major reason for flying at that altitude is money; After labor, fuel is the greatest expense for airlines. That's why airlines are constantly working to maximize their fuel efficiency. Cruising at 36,000 feet helps with that. The higher altitude means thinner air.


Why do planes fly at 40000 feet?

Planes are *optimized* to fly at certain heights to maximize the efficiency of their engines and their fuel consumption. So jet planes can fly a lot higher than propeller planes, so they do. They fly between 20,000 feet and 40,000 feet because they are designed and optimized to do just that.


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.


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.


Why do planes fly at 25,000 feet?

The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.


Can a plane fly at 60000 feet?

There are no specific regulations governing civil aircraft operations beyond the altitude of 60,000 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).


Do more experienced pilots fly bigger planes?

To fly a large wide-body aircraft, like the Boeing 777 and Airbus A350, you will typically need to be reasonably senior and ahead of a lot of other pilots on the list.


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.
