How long does rapid decompression last?

Rapid decompression typically occurs due to a sudden loss of cabin pressure in an aircraft, and it usually lasts less than 1 second. This rapid event can be caused by structural failure or malfunction of the cabin pressure system, resulting in a swift escape of the pressurized cabin air to the outside.

The duration is crucial because the moment a rapid decompression happens, cabin occupants may experience a sudden drop in pressure and need to respond quickly to avoid hypoxia or other adverse effects. The brief duration of less than 1 second means that pilots and crew must be trained to handle situations immediately after such an incident.

Understanding this aspect of rapid decompression is significant for proper emergency procedures and crew preparedness, highlighting the importance of quick reactions during such events.
