Description

  The present invention relates to a radar display device and a flight altitude display method of the radar display device.

  A radar display device used in an air traffic control system includes a display control device, an input / output device, and the like, and the radar display device exchanges data with a connected external device.

The radar display screen displays information such as the flight position of the aircraft necessary for air traffic control and the system time, weather, runway, obstacles, flight plan, and the like. The radar display screen in the related art has the following characteristics.
(1) The radar display screen displays a main window that displays information on the flight position of the aircraft and a plurality of sub-windows that display information such as system time, weather, runway, obstacles, and flight plans. The radar display screen displays a huge amount of information.
(2) A sub-window for displaying information such as the system time, weather, runway, obstacle, flight plan, etc. is superimposed on the main window for displaying information on the flight position of the aircraft.
(3) The main window for displaying the flight position information of the aircraft displays the position of the latitude and longitude of the aircraft and the position of the flight altitude of the aircraft. The position of the flight altitude of the aircraft is displayed as a character string. The controller reads the character string of the flight altitude of the aircraft.
(4) Since the aircraft flies in a three-dimensional space, the position of the flight altitude of the aircraft is very important information in air traffic control.

  A related art radar display screen will be described with reference to the drawings. FIG. 8 is a diagram for explaining a radar display screen of related technology.

  The radar display screen used for air traffic control displays an enormous amount of information to the controller.

  A main window 800 for displaying information on flight positions of aircraft displays character strings 820, 821, and 82n of flight altitude positions of a plurality of aircraft, and updates display contents at intervals of once every few seconds. The number of aircraft may exceed 100, and the aircraft whose latitude and longitude positions are close to each other is displayed on the main window 800 with overlapping character strings of flight altitude positions.

  Further, sub-windows 810, 811, 812, 813, and 814 for displaying information such as system time, weather, runway, obstacles, flight plan, etc. are displayed on the main window while updating the display contents as needed. As a result, the radar display screen has an enormous amount of information.

  Next, the character string of the position of the flight altitude of the aircraft will be described. FIG. 9 is a diagram for explaining a character string of the position of the flight altitude of the aircraft on the radar display screen of the related art.

  “080” in the second line of the character string indicates the position of the flight altitude of the aircraft. For example, “080” in the character string is 8000 feet.

  That is, the controller reads the character string of the position of the flight altitude of the aircraft. Then, the air traffic controller performs air traffic control by calculating the interval of the aircraft from the character string of the position of the latitude and longitude of the aircraft and the position of the flight altitude of the aircraft.

  At this time, when a plurality of aircrafts are flying in a narrow area, the character strings of the positions of the flight altitudes of the aircrafts are displayed in an overlapping manner, so that it is difficult for the controller to interpret the character strings.

  Techniques for displaying three-dimensional aircraft information in an air traffic control system are described in Japanese Patent Application Laid-Open Nos. 9-304526 and 2001-273599. A technique for displaying information such as system time, weather, runway, obstacles, flight plan, and the like is described in Japanese Patent Application Laid-Open No. 2009-009585.
