Cabin Pressure
Cabin pressure is the controlled air pressure inside a spacecraft or aircraft, maintained at a level safe for human occupants.
TECHNICAL DEFINITION
Cabin pressure is the artificially maintained atmospheric pressure within the habitable volume of a spacecraft or high-altitude aircraft, regulated to provide a breathable environment and prevent physiological effects of low external pressure on human occupants, typically set to a partial pressure of oxygen equivalent to Earth sea level.
BACKGROUND
The Bombardier CRJ700 series is a family of regional jet airliners that were designed and manufactured by Canadian transportation conglomerate Bombardier. Officially launched in 1997, the CRJ700 made its maiden flight on 27 May 1999 and was soon followed by the stretched CRJ900 variant. Several additional models were introduced, including the further elongated CRJ1000 and the CRJ550 and CRJ705, which were modified to comply with scope clauses. In 2020, the Mitsubishi Aircraft Corporation acquired the CRJ program and subsequently ended production of the aircraft.
