When flying at 36000 feet what altitude is the cabin pressure set at?
When flying at 36000 feet what altitude is the cabin pressure set at? To avoid that, airliners don't try to duplicate the air pressure at sea level. Instead, at a cruising altitude of 36,000 feet (10,973 meters), most commercial jets simulate the air pressure at an elevation of 8,000 feet (2,438 meters), about the same as Aspen, Colorado.
What is the cabin pressure at 35000 feet?
At the normal stratospheric cruising altitudes of 30,000–38,000 ft, the outside pressure is 0.3–0.2 atm, respectively, while the cabin pressure is maintained at a level equal to that found at altitudes between about 5500 ft and 8000 ft, or between about 0.8 and 0.7 atm.
What is the cabin pressure of Boeing 737?
they are set at Originals 8.5psi, Classics: 8.65psi , NG & Max: 8.95psi. According to these figures, the 737 NG and MAX have a maximum allowable pressure differential that exceeds (by 0.15 PSIg) that at which the cabin-pressure relief valve opens and vents the cabin pressure overboard.
How fast does a plane go at 35000 feet?
The Boeing 747-8 Intercontinental, the most recent 747 passenger variant, has a typical cruise speed of Mach 0.86 while flying at an altitude of 35,000 feet, according to Boeing.
Why do planes cruise at 37000 feet?
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.
At what altitude do you need pressurized cabin?
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.
