Can civilians fly above 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).

To maintain their operational ceiling of 70,000 feet (21,000 m), the early U-2A and U-2C models had to fly very near their never-exceed speed (VNE). The margin between that maximum speed and the stall speed at that altitude was only 10 knots (12 mph; 19 km/h).

Can a plane fly at 75000 feet? Airliners can't, jet airliners normally operate between 37,000 and 43,000 feet. US airliners normally don't go above 41,000 feet as they have restrictions applied to such flights. Concorde did fly at 60,000 feet routinely, but of course that is history now.

Most modern fighters, such as the F22, F35 or Eurofighter, can fly at altitudes around 65,000 feet.

Sandercock says there is a practical limit to how high Perlan 2 or any glider can fly. Cracking 100,000 feet would require flying at Mach 0.7 or Mach 0.8, and “giant amounts of thrust” would be required to push the aircraft through the transonic drag of those speeds, he says.

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.

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.

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.

The F-22 Raptor is indeed capable of flying at altitudes of up to 65,000 feet. This impressive feat is made possible by the jet's powerful engines, advanced aerodynamics, and high-tech materials used in its construction.

Can you fly at 80000 feet? The US Air Force U-2 reconnaissance aircraft flies at 72 000 feet almost every day for many hours. The world's fastest manned aircraft, the SR-71, flew for many years at 80 000 feet and higher.

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.

Commercial jets, however, have more sensors and control measures to prevent midair collisions, meaning they generally aren't affected by traffic. Private jets lack the high-tech sensors and controls of commercial jets, so pilots operating them typically fly at a higher altitude where there's less traffic.

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

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.

MORE DETAILS

A higher elevation will require a longer climb, meaning the aircraft will burn more fuel in order to reach its cruising altitude. Additionally, 35,000 feet gives more time for airline crew to address any unexpected mid-flight incidents.
