Embodiment 1

[0048] figure 2 It is a flowchart of a navigation method for a general aviation aircraft according to Embodiment 1 of the present invention. The navigation method can be applied to a navigator installed on a general aviation aircraft, thereby assisting a pilot to fly in a WYSIWYG manner. Specifically, as figure 2 As shown, the method includes the following steps S102 to S108.

[0049] Step S102: Obtain the location information of the general aviation aircraft.

[0050] Step S104: Read in the 3D real scene data corresponding to the location information.

[0051] Step S106: Obtain a 3D landscape low-altitude navigation data package, wherein the 3D landscape low-altitude navigation data package includes basic data, low-altitude obstacle data, threat area data, and security area data.

[0052] Step S108: Displaying a 3D navigation real scene map according to the 3D real scene data and the 3D landscape low-altitude navigation data package.

[0053] When the navigator adopts ...

Abstract

The invention discloses a navigation method, device and system for a general aviation aircraft. The navigation method for the general aviation aircraft comprises steps as follows: location information of the general aviation aircraft is acquired; three-dimensional realistic scene data corresponding to the position information are read; a three-dimensional landscape low-altitude navigation data package is acquired and comprises basic data, low-altitude barrier data, threatening area data and safety guarantee area data; and a three-dimensional navigation realistic picture is displayed according to the three-dimensional realistic scene data and the three-dimensional landscape low-altitude navigation data package. By means of the method, the device and the system, flying safety of the general aviation aircraft in low altitude and super-low altitude can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of general aviation, in particular to a navigation method, device and system for general aviation aircraft. Background technique [0002] With the gradual opening of low-altitude airspace, general aviation will be greatly developed. However, the safety of low-altitude and ultra-low-altitude flights is not optimistic. The reasons are not only low flying altitude, difficult tracking and monitoring, complex environmental conditions, and short time to deal with dangers. The flight safety environment of low-altitude and ultra-low-altitude general aviation aircraft is also deteriorating, and factors endangering safety are increasing, as follows: [0003] (1) The clearance environment deteriorates. The urbanization process is accelerating, and the existing airport has been surrounded by residential areas and emerging development areas. The clearance conditions of the airport are gradually deteriorating. Wh...
