FIELD: aviation.
SUBSTANCE: invention relates to aviation instrument-making and can be used in measurement and display systems, facilitating piloting of aircraft in event of failure of its primary flight navigation systems. For this purpose, integrated standby instrument system (ISPR) of aircraft includes first and second unit of galvanic isolation, first, second, third node of diode junction and electric power storage device is connected through first node of diode junction to onboard network via second node of diode junction to power bus orientation unit, connected via a third node of diode junction to power output of voltage switch, first device electrical isolation is connected between output of battery voltage monitoring device and first control input of orientation of unit, second control input is connected through a second device is galvanically isolated to output board network control unit of aircraft.
EFFECT: technical result is improvement of reliability and functionality.
