An emergency descent procedure is particularly necessary in situations where there are critical in-flight emergencies that pose an immediate threat to the safety of the aircraft and its occupants. When there is a fire or loss of cabin pressure, for example, it is essential to descend quickly to a safer altitude where breathable air is available, or to mitigate the risk of further damage from fire. This procedure is designed to ensure rapid descent while maintaining control of the aircraft, prioritizing the well-being of all on board.

In contrast, reaching cruising altitude is part of the normal flight phase and does not require an emergency descent. Turbulence, while uncomfortable, usually does not necessitate an emergency situation, as pilots are trained to manage it without resorting to rapid descents. Similarly, the need to land at a different airport can often be planned and executed without the urgency that defines an emergency descent. Thus, the circumstances involving fire or loss of pressure serve as the most compelling rationale for implementing emergency descent procedures.
