The fire alarm system is considered as an information and control system that performs the function of providing a light and sound signal about the occurrence of a fire in one of the compartments of the aircraft. The classification and characteristics of primary information sensors are given. At the same time, the main causes of sensor failures, non-detection and false alarm for a large class of aircraft alarm systems of various generations, which today account for more than 70% of the total number of fire alarm system activations are determined. An information model for the analysis of aircraft power plant fires was built and the main parameters and indicators were determined (dangerous gas temperature, dangerous temperature of bearings, chips in oil, dangerous vibration and rotation frequency, and other parameters), with the aim of transitioning from monoparametric to multiparametric control of a dangerous fire situation on board of the aircraft. The proposed information model can be used in the training of pilots to eliminate dangerous flight situations. Also, the paper examines a real disaster related to an engine fire as an example of the importance of timely determination of the first moment of fire occurrence. At the same time, more attention is paid to titanium fires and their causes.Downloads
