This SAE Aerospace Information Report (AIR) provides data and general analysis methods for calculation of internal and external, pressurized and unpressurized airplane compartment pressures during rapid discharge of cabin pressure. References to the applicable current FAA and EASA rules and advisory material are provided. While rules and interpretations can be expected to evolve, numerous airplanes have been approved under current and past rules that will have a continuing need for analysis of production and field modifications, alterations and repairs. The data and basic principles provided by this report are adaptable to any compartment decompression analysis requirement.
This report provides data and analysis methods for calculation of internal and external airplane compartment pressures during rapid discharge of cabin pressure. This revision provides several clarifications and corrections. Overall scope and content are substantially unchanged from the previous revision.

AC-9 Aircraft Environmental Systems Committee
Furthers the advancement of technology related to the research, design, test and utilization of aircraft environmental and anti-icing/deicing systems. Develops and updates standards, recommended practices, and information reports contributing to the quality, economy, and safety of commercial and military aircraft.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
