FIELD: devices enhancing safety of flights of civil aircraft; prevention of aircraft hijacking.
SUBSTANCE: proposed device is located on seats in aircraft saloon which is equipped with observation camera. Arm-rests of seats have holes in their center parts and are freely fitted on rods for rotation in horizontal plane excluding axial displacement. Articulated to ends of arm-rests towards the backs of seats are cylindrical permanent magnets at axial direction of magnetizing. Free ends of these magnets having unlike poles are received by axial hole of electromagnet mounted on rear side of back from opposite sides and are elastically connected by means of coil cylindrical spring. Electromagnet winding is connected at preset polarity to respective contacts of seat in pilot cabin indicating the number of seat connected with constant voltage source at adjustable amplitude.
EFFECT: enhanced safety of flights of civil aircraft.
