Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
A Delta Airlines flight had to return minutes after takeoff as passengers’ noses began bleeding when the cabin failed to pressurize as it climbed high into the air.. The Boeing 737-900 plane ...
The most common source of compressed air for pressurization is bleed air from the compressor stage of a gas turbine engine; from a low or intermediate stage or an additional high stage, the exact stage depending on engine type. By the time the cold outside air has reached the bleed air valves, it has been heated to around 200 °C (392 °F). The ...
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 ...
According to a health expert in Canada, even though the risk of a blood clot is low, given the number of people who fly, it is a public health risk. [9] It is reported in 2016 that the average distance between seat rows has declined to 79 centimetres (31 in), from over 89 centimetres (35 in), while the average seat size has shrunk to 43 ...
Your nose is gushing like a fire hose and it's really annoying.We get it–and you’re not dripping alone. After all, it’s virus season. And there are other things that can leave you with a ...
The control panel that controls cabin pressurisation and bleed air distribution on a Boeing 737-800. A fume event occurs when bleed air used for cabin pressurisation and air conditioning in a pressurised aircraft is contaminated by fluids such as engine oil, hydraulic fluid, anti-icing fluid, and other potentially hazardous chemicals.
