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).
Commercial aircraft typically have a maximum operational altitude ranging from 42,000 to 43,000 feet, while smaller private aircraft, including corporate jets, can reach even higher ceilings of up to 51,000 feet. On the other hand, military planes are capable of flying at approximately 50,000 feet and sometimes surpassing that threshold.
The airspace above 60,000 feet is referred to as "upper-Class E" airspace, which is subject to less stringent air traffic control regulations. It is worth noting, however, that the Federal Aviation Administration (FAA) retains ultimate authority over determining the precise altitude of an aircraft within any given airspace.
Can a Boeing 747 go up to 60,000 feet?
It is not possible for a Boeing 747 to ascend up to 60,000 feet. According to Aviation blogs, Lufthansa had boasted in the past about its 747-400 having the highest altitude in its fleet, with a maximum service ceiling of 44,947 ft (13,610 m). The German flag carrier also operates the modern 747-8, which has a service ceiling of 43,100 ft (13,137 m). Furthermore, the highest altitude an airliner can attain today, as reported by USA Today, is around 45,000 feet.
Commercial jetliners have a limited elevation ceiling of about 45,000 feet. While corporate aircraft can fly higher, slightly above 50,000 feet, they are specifically designed for such purposes. However, reaching an altitude of 60,000 feet would require super-efficient engines and glider-like wings. The engine of U2 was designed with no blade tip clearance to enable it to function at an altitude of 70,000 feet.
To summarize, a Boeing 747 is incapable of ascending up to 60,000 feet. The highest altitude a commercial jetliner can reach is approximately 45,000 feet, while corporate aircraft can fly slightly above 50,000 feet, but only if they are specifically designed for that purpose. Achieving an altitude of 60,000 feet would necessitate super-efficient engines and glider-like wings.
What will happen if a plane flies above 60,000 feet?
Flying at altitudes exceeding 60,000 feet poses various risks and dangers, as elucidated by the ensuing details obtained from the search findings:
- Structural instability:When an aircraft reaches approximately 43,000 feet, the pressure reaches a maximum of 9 PSI. Any elevation beyond this threshold could result in a catastrophic collapse of the aircraft's structure.
- Physiological perils:Exposure to altitudes above 43,000 feet, even for a brief period, without the provision of positive pressure breathing, can rapidly induce unconsciousness.
- Jet stream implications:Modern airplanes typically operate at cruising altitudes of 40,000 feet, while the effects of jet streams at 60,000 feet remain unclear and ambiguous.
- Cabin pressurization:Commercial flights entail exposure to hypobaric conditions, where the cabin pressure corresponds to an altitude of 5,000-6,000 feet. This results in a reduced fraction of inspired oxygen ranging from 0.17 to 0.15 compared to ground level.
- Efficiency considerations:Optimal performance for contemporary airliners is achieved within the altitude range of 35,000 to 42,000 feet. Within this sweet spot, the aircraft's engines operate at their highest efficiency.
- Aerodynamic challenges:Should a commercial airliner ascend excessively, it will encounter less dense air passing over its wings, consequently diminishing the ability to generate lift. This occurrence can lead to a loss of lift and potential stalling of the aircraft.
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.

FAQs
However, there presently are no civilian aircraft that can fly higher than 60,000 feet. The Concorde was certified to 60,000 feet, but typically flew at 45,000.
What civilian planes can fly at 60000 feet? ›
Some aircrafts are able to fly at much higher altitudes. For example, supersonic jets like the Concorde could reach altitudes of up to 60,000 feet (18,290 meters). Military aircrafts can go even higher - upwards of 70,000 feet (21,300 meters).
How high can a civilian fly? ›
"Most commercial airliners have what we call a 'service ceiling' of up to 45,000 feet," says former pilot Dan Bubb, now a professor at the University of Nevada, Las Vegas. "The service ceiling is the point where the airplane can no longer develop lift, and gravity begins pulling it down to the ground."
Can a plane fly at 70,000 feet? ›
The US Air Force states that the famous U2 spy plane routinely flies at over 70,000 feet, while PhyLink.com claims the U2 can cruise at up to 90,000 feet or 17 miles. Stealth Bombers cruise at up to 50,000 feet.
What is the highest civilian flight? ›
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 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 helicopters fly at 60000 feet? ›
Very few helicopters are pressurised so they typically do go above 10,000′ and cannot hover much above that. High performance helicopters can fly up to 20,000′ but the crew would need to be on oxygen. The altitude record for a helicopter is 40,000 that was an aircraft specially built for the attempt.
How high can you fly without FAA approval? ›
Fly at or below 400 feet in Class G (uncontrolled) airspace. Note: Anyone flying a drone in the U.S. National Airspace System (NAS) is responsible for flying within the FAA guidelines and regulations.
What is the maximum range of a civilian aircraft? ›
Long-range commercial aircraft can traverse over 11,000 miles nonstop, connecting cities and continents in ways once considered impossible.
Can planes fly at 65000 feet? ›
Some fighter jets, such as the F-15, can reach altitudes of up to 65,000 feet (19,812 meters), while others, such as the F-22, can reach altitudes of up to 60,000 feet (18,288 meters).
Sometimes however, the turbulence is a little more complicated and happens when the plane is not in a cloud - known as 'clear air' turbulence. This happens around the jet stream, which is in-effect a fast flowing 'river' of air, usually found at around 50,000 feet.
Can a plane fly at 100000 feet? ›
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.
What US aircraft can fly at 60,000 feet? ›
The Global Hawk, an unmanned surveillance aircraft, can fly at altitudes up to 60,000 feet. The F-22 Raptor, an advanced tactical fighter, has a maximum altitude of more than 50,000 feet.
What is the top speed of a civilian aircraft? ›
As a general rule, the speed of passengers aircrafts moves around Mach 77, equivalent to about 860 km/h, that is 14 kilometres per minute. At present, talking of commercial aircrafts, the Airbus A330Neo seems to be the fastest with a maximum speed of 1,061 km/h, and the Boeing B788, which gets up to 1,051 km/h.
