Description / Abstract:

This SAE Aerospace Recommended Practice (ARP) provides criteria for design and location of power supplies, controls, light fixtures, and associated equipment which are used to provide emergency illumination in transport aircraft, designed to comply with 14 CFR part 25 (Reference 1) for operation under 14 CFR part 91 (Reference 11) and 14 CFR part 121 (Reference 2), and also in compliance with FAA Advisory Circulars AC25.812-1A (Reference 3) and AC25.812-2 (Reference 10).

It is not the purpose of an ARP to specify design methods to be followed in the accomplishment of the stated objectives.


The purpose of this ARP is to provide criteria that will lead to and support existing regulatory standards of illumination for emergency evacuation in passenger or cargo transport aircraft such that the emergency illumination will facilitate egress under emergency conditions.

Consideration is given to existing requirements of the FAA and to the recommendations of aircraft operators and those involved in the manufacture or use of the Emergency Lighting System. Occupant safety is the primary objective, with appropriate provisions for crew system control taken into consideration. The criteria established herein are intended to produce an Emergency Lighting System that will comply with the Federal and International Regulations for Commercial Transport Airplanes. However, these recommendations are but one means of meeting the objective. Alternate practices may provide equivalent or superior results, although all of the recommendations within this document should still be considered when using an alternate means of compliance.
