For example, the information that must be considered in the design can be vast and complex, including information on runways, wireless facilities, aircraft, terrain, navigation standards, and so on. There are various ways to formulate airspace, including aviation security facilities,
You have to choose a formula that suits your 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.

Conventionally, this airspace design has been performed exclusively by hand.

It has been implemented in a variety of applications and has had many successes. Therefore, it is expected that the above-mentioned problem caused by the manual operation can be solved by automating the air space design.

However, the specific method and procedure of the airspace design work largely depend on the skill and skill of the designer in the past, and the whole work includes what kind of work elements and how these work elements are formed Everything that needs to be clarified in automation, such as being organized and in what order, is in the brain of the designer,
Moreover, it is not something that the designer is clearly aware of. Therefore, it is not easy to automate airspace design work,
In particular, it is very difficult to provide an excellent system that allows efficient and easy proper design.

Accordingly, it is an object of the present invention to provide an airspace design system that can easily and efficiently design an appropriate airspace.

Another object of the present invention is to provide an airspace design system that can easily evaluate a design result and create an effective presentation material.

Then, the process proceeds to step S29 in FIG. 6, where the printer output routine 1019 creates output data to the printer for the designated print target and passes it to the operating system for output to the printer 13.

Seventh, when the designed protected airspace is to be printed out on a map, the user sets the map on the plotter 11 and then presses the "plotter output" button 129 (FIG. 8, S55). Then, the process proceeds to step S3 in FIG.
Proceeding to 1, the plotter output unit 109 displays a predetermined plotter output screen (not shown), and the user sets an output file name, a scale value, or a map leaf name on the plotter output screen. Then, the process proceeds to step S33 in FIG. 6, and the plotter output unit 109 causes the plotter 11 to print the plan view of the protected airspace at the designated scale or at the area and scale corresponding to the designated map map leaf. And output data to the operating system for output to the plotter 11.

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.

Both the setting item and the defining item are items that must be set in order to design a protected airspace. Among these, the standard items include standard setting values that are generally used, and are automatically set as initial values in the present system (files (not shown) provided in the present system). And it is automatically displayed there 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 individually each time of design.

FIG. 9 shows, as setting items, an airport ID, an approach method name, a radio facility used, a final approach angle,..., And FIG. , The turn completion altitude correction value is shown, but this is an example in the case of a certain flight method. For each flight type (ie, for each type of airspace)
Only items necessary for the design of the airspace type are displayed on the setting item input screen and the prescribed 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 according to 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.

After setting the values of all the setting items on the setting item input screen shown in FIG. 9 and pressing the “display” button,
As described above, the setting item data and the specified item data are passed to the protection airspace creation routine 1014, and the protection airspace is automatically designed. The design calculation of the protection airspace is performed based on the set item data, the specified item data, the facility information 21 in the database 3, and the like in accordance with 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.

After that, when the "verification" button on the setting item input screen shown in FIG. 9 is pressed, the verification whether there is any obstacle or terrain infringing the protection airspace is automatically performed.
This obstacle verification is performed by the obstacle information 29 in the database 3.
This is a process of detecting, from among obstacles and altitudes registered in the altitude table 33, those that violate the designed protection airspace. When this obstacle detection is completed, the top view and cross-section of the designed protection airspace (if any)
The graphical symbols of obstacles and terrain that violate the protected airspace are displayed on the graphic screen 116 shown in FIG. 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).

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 to perform the design again. In this case, the user only needs to change the item values, and the airspace calculation and the obstacle verification are performed automatically. Therefore, the user's burden is extremely light and the design can be performed efficiently.

After designing and displaying the protected airspace with the “display” or “verify” button as described above, pressing the “register” button on the screen displays the design specification values (designated items) of the designed protected airspace. , Setting item values) are registered in the design specification information 27 of the database 3, and the designed shape data of the protected airspace are registered in the shape table 31 of the database 3.
