Emergency descent.
An emergency descent is a maneuver carried out by the flight crew which involves the aircraft descending as rapidly as possible to a lower altitude.
The maneuver is mainly performed due to a loss of cabin pressurization, uncontrollable fire, or any other event that requires the aircraft to descend to a lower altitude at the earliest possible time within the structural limitation of the aircraft.
There are set procedures the flight crew should follow under company operating procedures which are set by the guidelines of the aircraft manufacturer. Flight crew are routinely trained to perform this maneuver if ever necessary.
