Landing decision assistance system, landing decision assistance method, and landing decision assistance program

Abstract

The purpose of the present invention is to provide a landing decision assistance system, a landing decision assistance method, and a landing decision assistance program with which even a general user who is not a specialist can easily and correctly read information that is useful for making an aircraft landing decision. A landing decision assistance system (1) that provides information for assisting with making an aircraft landing decision, and that has a screen generation unit (220) for generating a variety of screens displayed on a display unit, and a display control unit (260) for causing the display unit to display the variety of screens generated by the screen generation unit (220). The screen generating unit (220) comprises an echo intensity screen generation unit (240) for generating an echo intensity screen. Echo intensity information included in the echo intensity screen is generated on the basis of subject-to-monitoring echo intensity data that has been acquired by a weather sensor, and the horizontal distribution of echo intensity is displayed on the basis of a summary statistic of the echo intensity in the airport vicinity in a predetermined altitude zone.

Description

technical field [0001] The present invention relates to a landing judgment assisting system, a landing judgment assisting method, and a landing judgment assisting program for providing information assisting the judgment of aircraft landing. Background technique [0002] In the past, devices that provide information on significant wind changes (low-level wind disturbance) at low altitudes are known as WTWS (Windshear and Turbulence Warning System: Windshear and Turbulence Warning System) developed by the Hong Kong Observatory (see Non-Patent Documents 1 and 2), NCAR (National Center for Atmospheric Research : JAWS (Juneau Airport Wind System: Juneau Airport Wind System) developed as a prototype by the US National Center for Atmospheric Research) (see Non-Patent Document 3), and an information providing system developed by the Japan Meteorological Agency (see Non-Patent Document 4, 5). The prototype of JAWS is based on the initial project implemented by NCAR in Hong Kong and ...

Problems solved by technology

[0010] However, the above-mentioned conventional graphic display devices are aimed at various users, but currently in Hong Kong, they are mainly used by staff of the Hong Kong Observatory, and in Japan, they are mainly used by experts such as staff of the Meteorological Agency, and there are navigation managers, pilots, etc. other than experts. The problem that it is difficult for ordinary users to read the required information accurately

[0011] For example, even if the low-level wind disturbance information is provided, the actual impact of the low-level wind disturbance on the aircraft and control (shaking, path departure, actual landing difficulty) varies with the aircraft type and the subjectivity of the pilot, so it is difficult to make the warning information directly effect on navigation

[0012] In addition, in actual flight, the following phenomenon often occurs: Even if the warning information is provided from the above-mentioned system, the aircraft can land without any problem, and on the other hand, although the wind disturbance information is not issued, it actually encounters wind disturbance when it is about to land. Phenomenon such as landing and go-around
