# Can jets fly at 80000 feet?

Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a 'service ceiling. ' For example, for the double-decker Airbus A380 'superjumbo' quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet.

## Can a plane fly at 80000 ft?

A: It depends on the wing and how much air can be kept flowing over it. The SR-71 routinely flew over 80,000 feet, but it was a very special wing. The space shuttle began encountering “usable” air around 100,000 feet during descent; it, too, was a very special wing and vehicle.

## What is the highest altitude a jet can fly?

All aircraft have a specified 'service ceiling' that defines the maximum height at which it should be operated. For most modern commercial jets today, this is around 41,000 feet. The exact level will depend mostly on the engines' performance (it is designed to be the maximum that still allows efficient operation).

## What flies at 80,000 feet?

The SR-71 regularly flew missions at speeds beyond 2,000 mph (Mach 3) and could survey more than 100,000 square miles of the Earth's surface per hour from a height of 80,000 feet (15 miles).

## Can a plane fly at 75000 feet?

Most commercial airplanes have a certified maximum altitude of about 40,000 to 45,000 feet. Regardless of its certified maximum altitude, if an airplane flies too high, it may fail in one or more ways. For starters, the engine may suffocate from a lack of oxygen.

## At what altitude can planes no longer fly?

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.

## 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.

## How high can a US fighter jet go?

Notably, the highest possible altitude for a military unit is not publicly shared for security reasons. Nonetheless, most fighter jets fly at an altitude between 45,000 and 51,000 feet. Some types, such as the F-22 Raptor, can reach as high as 65,000 feet due to the capability to rise vertically.

## How high can military aircraft fly?

Some business jets can soar up to 15,000 meters, while most military aircraft can fly at this altitude or even a little higher.

## What is the altitude limit for Boeing 747?

Boeing widebodies

Lufthansa previously bragged that its 747-400 could reach the highest altitude in its fleet, with a maximum service ceiling of 44,947 ft (13,610 m). The German flag carrier also flies the modern 747-8, which has a service ceiling of 43,100 ft (13,137 m).

## Can planes fly 70000 feet?

Military Reconnaissance (Lockheed U-2)

The only comparable aircraft would be Lockheed's SR-71 Blackbird. The U-2 was designed as a reconnaissance aircraft in the 1950s and had one engine, made by General Electric. The U-2 had a service ceiling of 70,000 feet.

## Is it safe to fly over 80?

Since commercial flights are pressurized to 6000 – 8000 ft, older adults with stable cardiovascular disease should be able to fly without risk.

## How high can an f22 Raptor fly?

It can soar 10 miles high and fly at supersonic speeds for extended periods of time thanks to an unprecedented capability known as “supercruise,” which propels the jet to speeds greater than Mach 1.5 without the use of afterburners. It can accelerate quickly and execute razor-sharp turns—even at high speeds.

## What is the max ceiling for a jet fighter?

Most fighter jets have a service ceiling below FL600, but there are a few that can fly higher (e.g. F-15 and F-22 with service ceilings of FL650, the MiG-25 again, and MiG-31 with the highest service ceiling of FL820+ for a fighter).

## Why do private jets fly higher?

Some Commercial Airplanes may have the capacity to reach altitudes higher than some Private Jets but very rarely do stick to the standardization of airspace usage. All the reasons private jets fly at a higher altitude are for increased safety and to reach their destinations faster.

## Is it possible to go Mach 10?

Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested. Mach 10 has, however, been achieved by a spacecraft - on November 16, 2004, NASA launched the X-43A, an air-breathing hypersonic vehicle, and was able to reach real Mach 10 while being pushed into the atmosphere.

## How long does it take a fighter jet to fly from California to New York?

Supersonic jets can fly from New York to L.A. in 2.5 hours (or less)

## What is the max age to fly a fighter jet?

What are the general qualifications to fly, including height? Becoming an Air Force Pilot requires you to meet strict physical, medical, vision and academic requirements. Applicants must achieve qualifying scores on the AFOQT exam, meet all requirements and pass a selection board prior to age 33.

## Which country has the best fighter jet in the world?

The US dominates the airspace when it comes to the world's most advanced fighter jets.

## What do pilots see when flying?

Pilots have a unique viewpoint while flying private or commercial aircraft. They get an unobstructed view of stunning natural sights, such as pink lakes and rectangular-shaped icebergs. Some have reported seeing UFOs, while others have flown over swirling hurricanes.

## How long would it take to fly in a 747 to the moon?

Did you know that flying a Boeing 747 to the Moon non-stop would take 17 days? Outer space is a big, empty place. The Earth's nearest neighbor, the Moon, is still an enormous 238,855 miles (384,401 Km) away. For comparison, you would have to circle the globe roughly 10 times to travel that distance.

## Can planes stop in air?

Airplanes stay in the air because of one simple fact-- there is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way, even if it's in midair 10 kilometers above the Earth's surface.
