Introduction
Draw airspaces to indicate where specific flight constraints apply
In this topic, you learn to use N-Tracking's Drawing tool to draw different shapes ("user-defined areas") on the map to represent airspaces where specific flight constraints apply.
We estimate that this will take 6 minutes to complete.
Detailed explanation
Why draw shapes on the N-Tracking map?
N-Tracking includes a tool, called the Drawing tool that you can use to draw shapes on the map to depict airspaces where flight constraints apply. Using this tool assists you in your flight planning tasks, as you can depict areas that represent danger zones, areas limited due to regulations, and even storms.
If you have an external provider that is supplying a feed that allows you to show controlled and/or restricted airspaces on the map, you can use the Drawing tool to add your own shapes to the map if that external source doesn't provide all the information you need.
In N-Tracking, the shapes you draw by entering the relevant coordinates in a table are called "user defined areas" or UDAs and you can color them as you see fit.
You can draw areas on your map that you share (display)with all other N-Tracking users in your airline and you can also draw private areas that do not display for others.
Click the Palette button.
Click the Drawing tool.
Name the area and enter the appropriate coordinates in the New Defined Area table.
For this example, enter the details of a new danger area named D33.
Click the Name input field.
The names of User Defined Areas display on the map. The first 12 characters of the name display at the center of the area. For longer names, the full name displays when you hover your mouse over the drawn area.
Enter D33 into the Name field.
Click the Color picker.
Choose a color on the larger color picker.
Click the red zone.
Close the Color picker, not the New Defined Area input area.
Click the Close (X) button.
Click the Latitude input field.
Enter 49.9 into the Latitude field.
Click the Longitude input field.
Your entry changes to green when accepted.
If N-Tracking identifies an incorrect entry, it displays the value in red.
Enter 005.4 into the Longitude field.
Repeat the previous step to fill the next two rows with:
- latitude -- 50.0 and
- longitude - 005.5.
Use the + button to add another row of coordinates.
Click the plus (+) button.
Click the Latitude input field.
For this example, 49.8 has been entered for you.
Click the Longitude input field.
Enter 005.4 into the Longitude field.
Click the Save button.
N-Tracking displays a notification on the map.
The danger zone (D33) you added to the map is located in Belgium.
Zoom in to see it better.
Click the Zoom (+) button.
Click the airport symbol.
Enter your text here
Click the airport symbol north-west of UDA D33.
Click the airport symbol.
The name of the airport, Saint Hubert military airport -- EBSU displays in the NAV information pane.
Next, click the airport symbol west of D33.
N-Tracking displays the name Bertrix -- EBBX for that airport.
Click the Layers button.
Click the AREAS tab.
At the 20 km zoom level, the Navaids layer is enabled.
In the AREAS tab, you can see your newly defined area in the UDA list. The list includes all user-defined areas, whether created by you, or created by other users and shared.
While you cannot change a UDA created by another user, you can use its slider to hide it if you don't want it to be visible on the map.
To modify any UDA, click 
.To delete a UDA, click 
.For this step, edit the user defined area you just created, D33.
Click the Edit button.
To make your UDA visible to other N-Tracking users in your airline, share it.
Click the Share slider.
Click the Save button.
If you stop sharing a User Defined Area, N-Tracking displays the following warning before you can proceed. Remember to share the revised UDA again after you complete any update.
Again, N-Tracking displays a notification about the update.
Click the Layers button.
The top of the list displays UDAs with asterisks before their names. These UDAs are private.
D33 now displays in the lower half, the shared area, of your UDA list, in alphabetical order.
