What is the maximum allowable cabin altitude?
What is the maximum allowable cabin altitude? (ii) Maximum cabin altitude is lim- ited to 40,000 feet.
Why is the Airbus A380 being discontinued?
However, the $445 million price tag of each aircraft was not sufficient to even cover the production cost, so with Airbus losing money on each A380, and with orders evaporating, it made economic sense to cease production.
What happens if a cabin is not pressurized?
If airplanes didn't pressurize their cabins, it could lead to insufficient oxygen as well as related medical problems like hypoxia. Airplanes need pressurized cabins because it ensures passengers, as well as crew members, receive an adequate amount of oxygen in the air they breathe.
What is the cabin altitude of a 737?
The pressurisation system of all series of 737 ensures that the cabin altitude does not climb above approx 8,000ft in normal operation.
How high can you fly without pressurized cabin?
For operations conducted under Parts 121 and 135, the flight crew must use oxygen when cabin altitudes are above 10,000 up to 12,000 feet after 30 minutes and at all times when above 12,000 feet. The general aviation pilot flying an unpressurized airplane will not normally operate above 25,000 feet.
Why are cabins pressurized to 8000 feet?
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.
What is the maximum altitude of the A380?
Many large widebodies have a ceiling of up to around 43,000 feet (12,500 meters). The Airbus A380, for example, is 43,100 feet and the A350 and Boeing 787 are the same (although the larger 787-10 and A350-1000 are lower at 41,100 feet and 41,450 feet). The A380 has a ceiling of 43,100 feet.
Can you get altitude sickness in a pressurized cabin?
after the flight. Even if you are flying a pressurized aircraft, altitude DCS can occur as a result of sudden loss of cabin pressure (inflight rapid decompression).
What happens if you open a plane door while the cabin is pressurized?
If the plane is somehow kept pressurized, the cabin pressure is usually equivalent of 6000–8000 ft, which is lower pressure than the outside at sea level. Which means as soon as you unlock the door, it will swing inwards with a lot of force, as air from outside rushes in to re-pressurize the cabin.
Why do commercial planes fly at 35000 feet?
The higher you fly, the more efficient it is The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.
Why is it necessary to be in a pressurized cabin when flying at 30000 feet?
If you were to fly at this altitude without today's technology, you would quickly begin to feel light-headed and may faint as your brain isn't receiving enough oxygen to function properly. This is because, at 30,000 feet, there is only 4.4 lbs of atmospheric pressure compared to the 14.7 lbs found at sea level.
What is the highest altitude a plane has ever flown?
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!
