One study of eight flights in Airbus A380 aircraft found a median cabin pressure altitude of 6,128 ft (1,868 m), and 65 flights in Boeing 747-400 aircraft found a median cabin pressure altitude of 5,159 ft (1,572 m).

The general rule is that planes should have cabin pressurization when they go above 10,000 to 14,000 feet. Can a pilot depressurize a cabin? Most aircraft cabins are pressurized to an altitude of 8,000 feet, called cabin altitude.
Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 74745,000 feet (13,700m).
The pressurisation system of all series of 737 ensures that the cabin altitude does not climb above approx 8,000ft in normal operation. However in 2005 the BBJ was certified to operate with a reduced cabin altitude of 6,500ft at 41,000ft (?P of 8.99psid above 37,000ft) to increase passenger comfort.
The Cabin Altitude of a pressurised aircraft is normally maintained at and altitude of 8,000 ft or less as a compromise between the physiological needs of the crew and passengers and the structural limitations of the aircraft. At 8,000 ft the use of supplemental oxygen is not required.
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).
How Fast Does a 747 Go To Take Off? A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
It was in 1977 that the highest current altitude record achieved by a manned air-breathing jet engine propelled aircraft was set, when Alexandr Fedotov flew to a height of 123,520 ft in a Mikoyan Gurevitch E-266M. That's about three times the normal cruising altitude of a passenger jet!
Emergency landings are tough at high altitudesHigh terrain can cause a plane to crash if the cabin depressurizes, the plane must descend to 10,000 feet before heading to a nearby airport. Airlines choose not to fly over Tibet to prevent such situations.
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.
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.
Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it. Q: Much beyond the certified ceiling, can an aircraft maintain altitude? A: During certification testing, airplanes are flown above the certified ceiling, but the performance is limited.
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.
And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times. And that above 15,000 feet each occupant of the aircraft must be provided supplemental oxygen. All of this is spelled out in Federal Aviation Regulations Part 91.211.
Low air pressure during air travel also decreases the amount of oxygen in the air. This effect is modest and generally not noticeable for healthy travelers. For patients with significant lung disease, a small decrease in available oxygen can cause significant symptoms, especially with exercise.
