Cabin pressurization

Index Cabin pressurization

Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft, in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. [1]

Aerotoxic syndrome

Aerotoxic syndrome is a phrase coined by Chris Winder and Jean-Christophe Balouet in 2000, to describe their claims of short- and long-term ill-health effects caused by breathing airliner cabin air which was alleged to have been contaminated to toxic levels (exceeding known, parts per million, safe levels) with atomized engine oils or other chemicals.
