There are a variety of ways to formulate airspace, and you need to choose a method that is appropriate for the aviation security facility to be used, approach, departure, and other factors. The specific calculations performed in the airspace design are also complicated. In designing, it is necessary to grasp the positional relationship between the airspace, terrain, and artificial obstacles not only from a planar viewpoint but also from a three-dimensional viewpoint taking altitude into consideration.

And output data to the operating system for output to the plotter 11.
[0073]
FIG. 9 shows an example of the setting item input screen described above. FIG. 10 shows an example of the above-described prescribed item input screen.
[0074]
Both the setting item and the stipulated item are items that must be set without fail in order to design a protected airspace. Among these items, the standard items include standard setting values that are usually used, and are automatically set as initial values in the present system (files (not shown) provided in the present system in advance). And it will be displayed automatically when you open the default item change screen). Therefore, the user only needs to open the specified item change screen and change the value of the specified item only when using a value other than the initial value. On the other hand, there is no such a standard setting for the setting items, so that the user needs to open the setting item input screen and set each time every design.
[0075]
FIG. 9 shows, as setting items, an airport ID, an approach method name, a used radio facility, a final approach angle,..., Etc., and FIG. 10 shows, as specified items, a far-edge angle outside a turning approach route, a protection airspace width, and turning completion. Altitude correction values are shown, but are illustrative for a particular flight regime. For each flight method (that is, for each type of airspace), only the items necessary for the design of that airspace type are displayed on the setting item input screen and the specified item setting screen. Therefore, the types of setting items and prescribed items on the screen are different for each flight method (airspace type). The user may simply make settings in accordance with the screen, and does not need to be aware of items to be set and items that need not be set for each flight method.
[0076]
After setting the values of all the setting items on the setting item input screen shown in FIG. 9 and pressing the “display” button, the setting item data and the specified item data are passed to the protected airspace creation routine 1014 as described above. The protection airspace is automatically designed. The design calculation of the protection airspace is performed based on the setting item data, the definition item data, the facility information 21 in the database 3, and the like according to a unique design method programmed in advance for each flight method to be designed. When the design of the protected airspace is completed, a plan view and a side view of the designed protected airspace are displayed on the graphic screen 116 shown in FIG.
[0077]
After that, when a “verification” button on the setting item input screen shown in FIG. 9 is pressed, verification of whether there is any obstacle or terrain infringing the protected airspace is automatically performed. This obstacle verification is a process for detecting, from the obstacle information 29 and the altitude table 33 registered in the altitude table 33 in the database 3, those that violate the designed protection airspace. Upon completion of this obstacle detection, graphical symbols of obstacles and terrain that infringe the protected airspace (if any) are displayed on the graphic screen 116 shown in FIG. Is displayed. FIG. 11 shows an example of a plan view and a sectional view of the airspace displayed in this manner (in this example, obstacles and terrain are not displayed).
[0078]
From the plan view and the cross-sectional view on the graphic screen 116, it can be easily determined whether the design result is appropriate or not. If the design result is not appropriate, it is possible to change the values of the setting items and the specified items and re-design. In this case, the user only needs to change the item values, and the airspace calculation and the obstacle verification are performed automatically, so that the user's burden is extremely light and the design can be performed efficiently.
[0079]
After designing and displaying the protected airspace with the "Display" or "Verify" button as described above, pressing the "Registration" button on the same screen will result in the design parameters (designated items, setting items) of the designed protected airspace.

It is possible to select whether or not to superimpose and display the protection airspace. In addition, for the obstacles, latitude / longitude, navigation assistance facilities, air routes, etc., the display mode can be selected to be displayed as a graphic symbol, text information such as a name (information), or both. it can. Here, the protection airspace auxiliary line is auxiliary information such as a line other than the outer frame of the protection airspace, for example, a center line. The design information is information on a protected airspace obtained by design calculation (for example, a correction value when input data is corrected, an azimuth, a distance, a latitude and a longitude obtained by calculation).
[0081]
After selecting display / non-display on the superimposition setting screen, if a button labeled “Setting” on the screen is pressed, if an airspace is already displayed on the graphic screen 116, If the airspace has not yet been calculated, when the airspace is calculated and displayed on the graphic screen 116, the data of the object to be displayed is extracted from the database 3 and the graphic of the object is displayed. (Or information) is created and superimposed on the graphics in the airspace and displayed on the graphic screen 116. In this case, the obstacle data is extracted from the obstacle information 29 of the database 3, the shoreline and contour data are extracted from the terrain information 32, the navigation support facility data is extracted from the facility information 21, and the air route data is extracted from the route information 25.
