A system for extracting a ground route of an aircraft includes an airport surface detector acquiring ground movement information of an aircraft detected in an airport, a mapper acquiring node information of the airport from a database and mapping the ground movement information with the node information, a route detector detecting taxi route information of the aircraft by collecting adjacent node information of a mapped coordinate and erasing redundant node information among collected adjacent node information, a node identifier identifying start node information or end node information of a taxi route by using stand node information of the aircraft, and a final route extractor extracting a final taxi route including an extracted shortest route by dividing the taxi route into a plurality of sub-routes and applying a shortest route algorithm to the divided sub-routes.

System and method of extracting ground route of aircraft, and computer-readable recording medium thereof

The present invention relates to a method for coupling a flight plan and a flight path using ADS-B information, and more specifically to a method for coupling a flight plan and a flight path, wherein a flight data processing unit of an air traffic control system or an arrival management system separately and directly receives ADS-B information such that the received ADS-B information can be used for coupling a flight plan and a flight path of an aircraft.

Method for coupling flight plan and flight path using ADS-B information

Provided is a test tool for an airspeed indicator of an aircraft, including: a cylinder portion including an insertion groove with a predetermined amount of space, and of which one end is sealed by a cover and includes an injection portion on the cover so that the insertion groove passes through a pitot tube, and of which another open end includes a protruded step around its inner circumferential surface; a piston portion being inserted into the insertion groove to reciprocally move within the insertion groove, and including a protrusion portion having a size and a shape corresponding to an aperture of the insertion groove, and a bar-shaped knob portion being extended from the protrusion portion; and a display portion being formed of a transparent material on an outer surface of the cylinder portion to display a location of the protrusion portion reciprocally moving within the cylinder portion.

Quick test tool and method of aircraft airspeed indicator

There is provided a frequency transceiver for automatically controlling a TX/RX IF signal in a radar or a communication system, which transmits/receives an RF signal. The frequency transceiver includes a local oscillator for oscillating a VHF proportional to a VHF oscillation control voltage, a first IF processor for mixing an external RF signal with the VHF signal oscillated by the local oscillator and converting the RF signal into an IF signal proportional to the VHF signal, a second IF processor for mixing the RF signal oscillated by the RF oscillator with the VHF signal oscillated by the local oscillator, converting the RF signal into an IF signal proportional to the VHF signal, and converting the converted IF signal into a voltage, a control signal generator for generating a control signal to control the VHF signal oscillation of the local oscillator according to an output voltage of the second IF processor, and a VHF oscillation controller for outputting the VHF oscillation control voltage to the local oscillator according to the control signal generated from the control signal generator.
