# Airports<no value>
The **Airports** option from the [Debug](../../debug_info/) menu will open up the following sub-menu:

{{< image-center
    src="images/2_DevMode/menus/debug/airports/options_13.png"
    alt="The Airports Sub-Menu" >}}

initially only two of the options from this sub-menu will be available to you:

-   **Draw Debug**: Enabling this will turn on the airport debug overlay drawn onto the simulation scene, and also unlock the rest of the debug options.
-   **Airport Coloring**: This is a toggle that will enable/disable surface colouring for the airport (by default this is on).

 

Once you enable **Draw Debug**, airports will display some basic debug information:

{{< image-center
    src="images/2_DevMode/menus/debug/airports/options_14.png"
    alt="The Basic Debug Draw For An Airport" >}}

This will show the following details:

-   **Taxiways**: These are shown as purple lines.

-   **Taxiway Points**: These are shown as cyan opposing circles.

-   **Runways**: These are shown as cyan rectangles

-   **Ground Vehicle Paths**: These are shown as orange lines.

-   **Aircraft Parking Spots**: These are shown as green concentric circles, where the inner circle illustrates the minimum area for the parking spot and the outer circle shows the maximum wingspan permitted.

-   **Ground Vehicle Parking Spots**: These are shown as dark blue concentric circles.

-   **Helipads**: These are flagged by a light blue "H" symbol.

 

The options that enabling Draw Debug opens up can add further information to the simulator overlay:

-   ##### Additional Taxi Info

    Enabling this will show text overlays with information about the taxiway points as well as the different parking spots associated with the taxiways.  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_15.png"
        alt="Displaying Additional Taxiway Information" >}}

-   ##### Taxi Width

    When enabled, taxiways will be represented using rectangles showing their width.  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_16.png"
        alt="Taxiway Width Being Shown In The AIrport Debug Drawing" >}}

-   ##### Additional Parking Info

    As the name implies, enabling this will show additional information about the different taxiway parking spots.  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_17.png"
        alt="Additional Taxiway Parking Information Being Shown In The Sim" >}}


-   ##### Parking Occupation

    Enabling this option will permit you to get information about airport parking usage and spawned AI aircraft. On selecting this option a new window will open where you can select an airport to view the various parking spots within it (the dropdown at the top of the window will initially show all loaded airports, sorted by the distance from the player). After selecting an airport the window will change to show the following two tabs:

    - The **Parkings** tab shows all the [TaxiwayParking Objects](../../../editors/scenery-editor/objects/taxiwayparking-objects/) available at the airport, and whether it is occupied or free:

        {{< image-center
            src="images/2_DevMode/menus/debug/airports/options_parking_occupation_1.png"
            alt="The Parking Tab Of The Parking Occupation Window" >}}
        
        The toggle at the top of the tab, **Draw Position**, can be used to toggle on/off the bounding sphere and legend for each of the parking spots, and under that you have the **Filter Parkings** input box, which can be used to filter down the parkings shown based on the input text. Free parking spots have no additional options, but if a spot is occupied, you can expand it to get information on the aircraft currently parked as well as it's **AI State**. Additionally, there will be two extra buttons to show debug information about the aircraft within the world ({{< image-icon src="images/2_DevMode/menus/debug/airports/options_parking_occupation_2_icon_eye.png" alt="Eye Icon" >}}) and to show the current path ({{< image-icon src="images/2_DevMode/menus/debug/airports/options_parking_occupation_2_icon_tag.png" alt="Tagged Path Icon" >}}), either taxiing *to* or *from* the flightplan.

    -   The **Spawner** tab is used to spawn aircraft, either on a parking spot, or on a flight using a [flightplan file](../../../../content-configuration/mission-xml-files/flight-plan-xml-pln-file-properties/).

        {{< image-center
            src="images/2_DevMode/menus/debug/airports/options_parking_occupation_3.png"
            alt="The Spawner Tab Of The Parking Occupation Window" >}}
        
        This tab has two sections. The first is for **Parked** aircraft, where you can select an aircraft from the drop-down list and then click the {{< button "Spawn" />}} button to spawn the aircraft on one of the available parking spots. If you have a PLN (flight plan) file, then you can use the second section, **Enroute**, to select an aircraft, the PLN file, and the position along the route to spawn at. You may also select to make the landings "touch and go" or not. When ready, click on the Spawn button to spawn the aircraft. All aircraft will be listed at the bottom of the window with buttons to show debug information about the aircraft within the world ({{< image-icon src="images/2_DevMode/menus/debug/airports/options_parking_occupation_2_icon_eye.png" alt="Eye Icon" >}}), show the current flight path ({{< image-icon src="images/2_DevMode/menus/debug/airports/options_parking_occupation_2_icon_tag.png" alt="Tagged Path Icon" >}}), or delete it ({{< image-icon src="images/2_DevMode/menus/debug/airports/options_parking_occupation_2_icon_bin.png" alt="Delete Icon" >}}). Note that these sections replicate the functionality of the SimConnect functions [`SimConnect_AICreateParkedATCAircraft_EX1`](../../../../programming-apis/simconnect/api-reference/ai-object/simconnect_aicreateenrouteatcaircraft_ex1/) and [`SimConnect_AICreateEnrouteATCAircraft_EX1`](../../../../programming-apis/simconnect/api-reference/ai-object/simconnect_aicreateenrouteatcaircraft/).


-   ##### Runways Info

    Enabling this will show additional information about the runways in the airport.  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_18.png"
        alt="Additional Runway Information Shown Overlayed In The Sim" >}}


-   ##### Runways Deformation

    When this is enabled, points will be shown at either end of the runway showing any deformation values.  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_19.png"
        alt="Runway Deformation Values Shown In The Sim" >}}


-   ##### Runway ILS

    When this option is enabled, debug information about any ILS beacons will be included in the scene at their position within airports. Additionally, the heading and angular spread of the beacon will be shown using semi-transparent polygons:  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_35.png"
        alt="The Airport ILS Debug Overlay" >}}


-   ##### Debug Navigation Data

    This option will display data related to the different radio navigation beacons that have been defined for the airport, for example: {{< glossterm >}}vor{{< /glossterm >}}, {{< glossterm >}}ndb{{< /glossterm >}}, Waypoints, etc...  

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_20.png"
        alt="Debug Navigation Overlay" >}}


-   ##### Debug Airport Override

    When enabled, this will show information about any aspects of the airport that have been overridden by an add-on.


-   ##### Apron Control

    Selecting this option will open the **Apron Control** debug window. The window is initially split into two parts, where the top shows those airports that have a custom apron control setup, and then the bottom half shows the airports that do not have custom apron control and rely on the *fallback* services.

    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_apron_control_1.png"
        alt="The Apron Control Debug Window" >}}
    
    If you click on any of the listed airports the selection will then expand to show further options which permit you to visualise the apron control services, status, and positions in the world:
    
    {{< image-center
        src="images/2_DevMode/menus/debug/airports/options_apron_control_2.png"
        alt="The Apron Control Debug Window Showing The Services At An Airport" >}}
    
    Within each airport you can:

    -   show/hide the navigation graphs of the vehicles handled by this Apron Control. They will appear as spheres for the nodes, and lines for the edges
    -   see a list of all the vehicles handled by this Apron Control, along with the current state of their navigation service.
    -   see a list of the global navigation services (also called CabinServices) spawned by the Apron Control, and expanding them will show data related to the navigation service.
    -   see the current contexts referring to service requests, along with their current state.
