No-Fly-Zones
No-fly zones (NFZ) are areas on the map where flying is prohibited. NFZs are divided into two categories – Aerodrome zones, which are built into UgCS, and Custom zones which the operator can create.
The operator can create a Custom NFZ of either two shapes:
- Prism
- Cone
NFZ can be created by clicking on one of the two bottom icons on the No-Fly-Zone drawing tools and shift-click on the map.

To create a prism-formed NFZ, at least 3 points are necessary. The cone NFZ requires only one point. To finish creating an NFZ, click on the selected NFZ icon again. To edit the finished NFZ click it on the map. To delete an NFZ click on the trash can icon on the editing screen.
The following parameters for each of the NFZ can be changed:
- Name of NFZ
- No-Fly Zone starts from – altitude from which the NFZ begins. By default, this parameter is set to 0 m AGL.
- Ground or sea-level – change the altitude origin between AGL and AMSL
- Height – the altitude NFZ ends. By default, this parameter is set to infinity.
For the cone NFZ there are two additional parameters:
- Base radius – radius of the base of the flight zone. By default, this is set to 100 m.
- Top radius – radius of the top of the flight zone. This parameter can be used only if the height parameter for the cone NFZ is not infinity.
Note: If NFZ width is less than one meter it is not taken into account for route calculation.
To change the visibility of NFZ:
Click on the Map options (globe icon) button at the very top right-hand corner of the screen;
Click on the Layers button.
In the new window, deselect Aerodrome zones or Custom zones so that they are no longer displayed on the map.

Keep in mind, that this operation does not disable the NFZ, it simply hides them.
The No-Fly Zones can be disabled in the parameter window of the route, by deselecting the Aerodrome zones or the Custom zones. The route’s parameter window is displayed during the creation process of a new route, or it can be accessed by selecting the Parameters button of the route’s card Parameter setting dropdown.
UgCS will not be able to calculate a route if any waypoint is in an NFZ.
