SAE ARP 997C PDF
The purpose of this SAE Aerospace Recommended Practice (ARP) is to establish criteria for the installation of emergency equipment that shall permit its efficient use and encourage standardization, thereby reducing reorientation of crewmembers to equipment accessibility while working on differing types, models, and series of transport-category aircraft. This does not preclude the requirement to pre-flight check all emergency equipment relative to its location, availability, and operational status.
