False actions of the aviation fire protection system caused by disturbances in power circuits

Abstract The article presents the results of simulation tests SSP-FK aviation fire protection system and identification main causes its false operation on many airplanes helicopters Polish Armed Forces with use a diagnostic simulator built at ITWL. performed statistical analyzes pointing to execution blocks as key factors in signaling are discussed. Selected test developed model actuator unit under conditions disturbances occurring supply circuits (in particular instantaneous voltage drops) presented. effectiveness presented method system, which can be used train engineering service pilots, support work Aircraft Accident Investigation Commission, was pointed out.
