Why don t commercial jets fly at 45000 feet?
Why don t commercial jets fly at 45000 feet? Flying at 45,000 feet plus altitude might avoid traffic and weather, but it also comes with its own risks. For example, if the aircraft was to rapidly depressurize and emergency oxygen fail, the time of useful consciousness at 45,000 feet is just nine to 15 seconds.
Why do private jets fly higher than commercial?
1 Because they can - smaller and lighter aircraft In general, private jets have a higher power-to-weight ratio, allowing them to ascend faster and maintain higher speed at higher altitudes. Commercial aircraft on the other hand, will be much heavier (even relative to their size) with passengers and payload.
How high is too high for planes?
The maximum height that a commercial airplane is allowed to reach when they fly is 42,000 feet, as this is the universally approved maximum altitude. This max altitude for airplanes is known as the “service ceiling.” Most commercial air jets fly at such a high altitude because it is known to optimize efficiency.
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.
How high can a 787 fly?
' For example, for the double-decker Airbus A380' superjumbo' quadjet, the service ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet. However, the stretched-fuselage 787-10 comes in a little lower, at 41,100 feet. Want answers to more key questions in aviation?
Can a plane fly higher than Mount Everest?
If you've traveled by air, you know that sometimes it inspires frustration and questions. Planes cruise almost 7 miles high in the sky. That's 7,000 feet higher than Mount Everest. A major reason for flying at that altitude is money.
Can a plane fly at 300000 feet?
white was the first pilot to fly any aircraft faster than mach 4, 5 and 6, as well as the first to fly above 200,000 and 300,000 feet. he set the only official world record of the X-15 program when he flew to 314,750 feet on July 17, 1962, a fédération aéronautique internationale altitude record that still stands.
Do big planes feel less turbulence?
The bigger the plane, the better! Any plane can experience turbulence, but larger planes weigh more and don't feel the impact of wind changes as much as a smaller plane. Specifically, the Airbus A380 handles turbulence very well! The A380 is a large plane mainly used for international flights.
What happens if a plane flies at 60000 feet?
Flying beyond the altitude of 60,000 feet entails the risks of structural failure, physiological hazards, and decreased operational efficiency. Commercial airliners are specifically engineered for lower altitudes, and exceeding these prescribed limits may also give rise to aerodynamic complications.
Can a plane fly at 50000 feet?
All planes are designed to fly whatever they need to achieve their mission (military or civilian). Some can fly at 50,000 or above because their missions require it, such as the U-2 and the SR-71 reconnaissance planes. A U-2 flew over the Chinese balloon at about 60,000 ft. Some fighter aircraft can reach 50,000 also.
Can planes fly at 45000 feet?
Although private jets tend to cruise at an altitude of 41,000 feet, they have the capability of reaching heights of 45,000 feet. Altitudes higher than this tend to be reserved for military aircraft that comfortably reach an altitude of up to 51,000 feet.
Can a plane reach 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).
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 happens if a commercial 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 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.
Can turbulence bring down a plane?
Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened. In 1966, human error and turbulence combined to bring a plane down over Mount Fuji.
