FLIGHT AND NAVIGATION SYSTEM OF A TRANSPORT AIRCRAFT Russian patent published in 2021 - IPC G01C21/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of flight and navigation systems of a transport aircraft. The digital flight and navigation system of the transport aircraft includes the equipment of the current flight and navigation parameters (IS-1, IS-2, ADS, RA), a channel switching unit, a digital-to-analog converter, a command execution unit, a radio communication system with a receiver-transmitter of communication with the control panel at the initial and final points of the route, a route program unit, a take-off and landing unit, two on-board digital computers, two inertial systems. The claimed system also contains a trajectory correction channel consisting of a trajectory correction unit, a receiver of a satellite navigation system, and a receiver of a radio-distance system operating from three or more ground-based radio-distance systems that provide navigation and landing approach accuracy. At the same time, it additionally includes a correction channel of landing trajectory consisting of a correction unit of landing trajectory that interacts with the component units of the flight and navigation system.

EFFECT: technical result is an increase in the accuracy and safety of piloting the aircraft.
