METHOD FOR PROVIDING BACKUP RETURN OF SINGLE-SEAT COMBAT AIRCRAFT IN EVENT OF CENTRAL COMPUTER FAILURE Russian patent published in 2023 - IPC G01C23/00 B64C19/02 

FIELD: aircraft.

SUBSTANCE: methods for ensuring the flight safety of an aircraft. In the process of pre-flight preparation, elements of the flight task necessary to ensure a safe return are loaded from the central computer into both multifunctional indicators with a push-button frame containing a computing part, and if the central computer fails, both multifunctional indicators process information from the general aircraft radio-electronic equipment and a signal concentrator unit, indicate spatial flight parameters based on information from flight navigation equipment and an integrated control system, providing indication of information from landing aids, indicate the route to the return airfield and the direction of approach to the airfield based on information from elements of the flight mission or manually specified by the pilot through multifunction buttons, indicate the state of on-board systems, fault messages, warning and emergency alarms, which are issued to the communication system for voice notification of the pilot, provide the ability to control the communication system, view and scroll through fault messages through the multifunction buttons of the multifunction indicator. The signal concentrator unit converts information in analog form from general aircraft equipment and transmits it to multifunctional indicators via radial communication lines, begins to execute algorithms for direct automatic control of the air conditioning system and ensures synchronization of the operation of multifunctional indicators by transmitting operating parameters and status between them via radial communication lines, and the backup instrument system indicator, equipped with a screen and an autonomous inertial positioning device, provides an indication of the aircraft's attitude and landing assistance based on information from flight navigation equipment and an integrated control system received via radial communication links.

EFFECT: increasing the fail-safety of a single-seat combat aircraft and expand the functionality of the pilot in the event of a failure of the central computer.
