Abstract: The invention concerns a system for deicing and/or defogging an aircraft surface (4) comprising: a temperature sensor (5) located proximate said surface (4) and adapted to generate a temperature information (TPT); a computer (20) adapted to generate a control information (CMD) based on the temperature information (TPT) and to transmit the control information (CMD) over a computer network (18) of the aircraft; an electric power supply system (8) located in the electrical center of the aircraft (18) and comprising a switch (12) adapted to be switched based on the control information (CMD); a heating element (6) located proximate said surface (4) and electrically powered via said switch (12). The invention also concerns a method for controlling such a system.

Abstract: The control system (1) comprises at least one control panel (P1, Pn) comprising a plurality of operable control means (2) for controllable pieces of equipment (EC1, ECk) of the aircraft, each of which is controlled by first and second computers (3A1, 3Ak, 3B1, 3Bk), and a communication system (4) comprising a first and a second communication channel (5, 6) which are separate from each other and follow different paths (C1, C2), the first communication channel (5) connecting the control means (2) to the first computers (3A1, 3Ak) and the second communication channel (6) connecting the control means (2) to the second computers (3B1, 3Bk), each of said communication channels (5, 6) comprising two different digital communication buses (8, 9; 10, 11).

Abstract: A system for monitoring a plurality of zones includes detection devices, disposed in the zones to be monitored, that emit detection signals on two different channels. A processor processes the signals and includes first and second computers, respectively connected to one or the other of the channels, and electrically isolating links that connect the first and second computers.

Abstract: System for monitoring a plurality of zones. The present invention comprises detection devices (DZM1 to DZM4, DZAP, DZLG), disposed in the zones (ZM1 to ZM4, ZAP and ZLG) to be monitored and able to emit detection signals on two different channels, as well as means (FDU) for processing said signals. These processing means (FDU) comprise first (C1A, C3A) and second (C2B, C4B) computers respectively connected to one or the other of said channels and electrically isolating links (3) connecting said first and second computers. An advantageous application of the invention relates to the detection of fire in unpressurized zones of aircraft.
