Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...
At 40,000 ft (12,192 m), the ambient air pressure falls to about 0.2 bar, at which maintaining a minimum partial pressure of oxygen of 0.2 bar requires breathing 100% oxygen using an oxygen mask. Emergency oxygen supply masks in the passenger compartment of airliners do not need to be pressure-demand masks because most flights stay below 40,000 ...
The percentage of oxygen in the air at high altitudes isn't the issue, since that stays relatively constant at about 21% until about 70,000 feet. The problem is the lack of air pressure.
that the use of mobile phones is not allowed during flight, unless placed in "airplane mode" or the wireless capability is turned off, unless the aircraft has cellular connection and/or Wi-Fi that laptops and other electronics may only be used once the aircraft is at cruising altitude or the captain turns off the fasten seat-belt signs
Airplane cabins are pressurized to maintain the equivalent of 8,000 feet (2,438 meters) of elevation, meaning the air pressure and oxygen levels are lower than what most people experience on Earth.
Cabin pressurization is the active pumping of compressed air into the cabin of an aircraft in order to ensure the safety and comfort of the occupants. It becomes necessary whenever the aircraft reaches a certain altitude, since the natural atmospheric pressure would be too low to supply sufficient oxygen to the passengers.
Drinking alcohol on airplanes, particularly during long-haul flights, can negatively impact the body’s oxygen saturation and increase heart rate, says Dr. Tadwalkar.
Title 14 CFR – Aeronautics and Space is one of the fifty titles that make up the United States Code of Federal Regulations (CFR). Title 14 is the principal set of rules and regulations (sometimes called administrative law) issued by the Department of Transportation and Federal Aviation Administration, federal agencies of the United States which oversee Aeronautics and Space.
