Product Code:SAE ARP1178
Title:Aircraft Evacuation Signal System
Issuing Committee:S-9b Cabin Interiors And Furnishings Committee
Scope: Because of the necessity of advising all crew members instantly and simultaneously of an existing or impending cabin evacuation, this recommended practice has been prepared. The development of large aircraft with remote flight compartments, cabin attendant stations, and galleys have made the necessity of such a warning system more evident. This recommended practice establishes criteria for the development and installation of an aircraft emergency signal system to permit any crew member to inform all other crew members that an emergency evacuation situation exists and that an evacuation has been or should be immediately started. NOTE: It is not the purpose of this ARP to specify the design method, mechanism or equipment to be used in the accomplishment of the objectives set forth herein.
