Embodiment Construction
[0041] The present invention is an aircraft navigation information generation device for generating aircraft navigation information for aircraft navigation, as long as a plurality of wind direction data and wind speed data at predetermined heights on the landing path acquired by meteorological sensors, runway azimuth data, aircraft machine Type information is used as input information to infer the difficulty of aircraft landing on the runway, and generate information that is highly correlated with actual navigation failures and accidents. Its specific structure can be any structure.
[0042] For example, the specific form of the weather sensor in the present invention may be any sensor such as weather radar or weather light radar as long as it can acquire wind information.
[0043] Below, based on Figure 1~4 The aircraft navigation information generating device 10 as one embodiment of the present invention will be described.
[0044] The aircraft navigation information gener...

The present invention provides an aircraft navigation information generation device, an aircraft navigation information generation method, and an aircraft navigation information generation program that generate information highly correlated with actual navigation failures and accidents. It is an aircraft navigation information generation device (10) for generating aircraft navigation information for aircraft navigation, and the aircraft navigation information generation device (10) obtains wind directions at a plurality of predetermined heights on a landing path acquired by a weather sensor (S) Data, wind speed data, runway azimuth data, and aircraft model information are used as input information to infer the difficulty of landing the aircraft on the runway.
Description
technical field [0001] The present invention relates to an aircraft navigation information generation device for generating aircraft navigation information for aircraft navigation, an aircraft navigation information generation method, and an aircraft navigation information generation program. Background technique [0002] For aircraft, the wind disturbance on the landing path changes the flight route and attitude of the aircraft irrespective of the pilot's intentions, which becomes the main cause of flight failures such as go-arounds and alternate landings, and accidents such as hard landings. The large-scale wind disturbance (wind shear) with a change scale of 1-10 km mainly changes the flight path, and the small-scale wind disturbance (turbulence) with a change scale of 10-100 m mainly changes the flight posture. The International Civil Aviation Organization (ICAO) requires that information on wind disturbance be provided to aircraft for a landing path whose height from th...
