JPS63191924A - Residual fuel warning device - Google Patents

Abstract

PURPOSE:To send a warning of the rest of fuel to a ground controller and to assist the safe flight of an aircraft by using a radio data link between the aircraft and a ground radar, and obtaining fuel rest information on the aircraft. CONSTITUTION:A signal received by a radar antenna is inputted to a data link control part 4 through a transmitter receiver 3. A control part 4 makes questions and answers by using the aircraft number in a track data file 5 to monitor the aircraft. A fuel rest value sent from the aircraft 1 is processed by a trackable distance arithmetic part 8 together with the equipment kind data in a flight plan data file 7 to calculate a trackable distance, which is sent to a warning decision part 9. The decision part 9 compares the flight plan distance with the trackable distance and displays a warning on a warning display part 10 when a margin distance is smaller than a constant value. The air traffic controller makes a communication with an aircraft pilot in response to the warning display to take the best countermeasure for safety.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to flight safety of aircraft in air traffic control systems.

[Conventional technology]

Traditionally, information on an aircraft's remaining fuel was obtained by the pilot checking the plane's meters.

[Problem that the invention seeks to solve]

In the past, only the pilot was responsible for managing the remaining fuel in an aircraft, so accidents have occurred where the pilot's carelessness has caused the aircraft to run out of fuel, resulting in an emergency landing at an unscheduled airport, or in the worst case scenario, a crash. Ta.

[Failure to solve the problem]

The remaining fuel warning device of the present invention is obtained from the remaining fuel information of the aircraft obtained by the wireless data link between the aircraft and the ground radar, the position information of the aircraft obtained by the radar, and the flight plan information of the aircraft. It has a function that calculates the aircraft's cruising range and the flight distance from its current flight position to the destination aerodrome based on the aircraft type and destination aerodrome, and sends a warning to the radar indicator if the cruising range is exceeded.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the remaining fuel warning device according to the present invention. In FIG. 1, 1 is an aircraft that responds to an interrogation signal from a radar antenna 2 with location information and remaining fuel information along with the aircraft's strange rocks. The signal received by the radar antenna is input to the data link control section 4 via the transceiver 3. The data link control unit uses the aircraft number in the track data file 5 to correlate with the received data, makes inquiries and answers at regular intervals, and continues to monitor the aircraft. The position information of the aircraft is based on the route information to the destination aerodrome obtained from the flight plan data file 7. The flight distance calculation unit 6 calculates the aircraft position information, and the flight distance calculation unit 6 calculates the flight distance from the current position to the destination aerodrome to the warning judgment unit 9. send. The remaining fuel value is calculated as the possible cruising distance by the cruising distance calculating section 8 together with the model type data of the responding aircraft in the flight distance data file 7, and is sent to the warning determining section 9. The warning determination section compares the scheduled flight distance and the possible cruising distance, and if the margin distance is less than a certain value, a remaining fuel warning is displayed on the warning display section 10. Air traffic controllers can communicate with the pilot of the aircraft when a fuel remaining warning is displayed on the radar indicator and take the most appropriate action.

〔Effect of the invention〕

As explained above, the present invention uses a wireless data link between an aircraft and a ground radar to obtain information on the aircraft's remaining fuel, thereby issuing a remaining fuel warning to ground controllers, thereby supporting the safe flight of the aircraft. There is.
