FSLTL User Guide

1. Start MSFS and load it into a flight
2. Open the FBW Installer if it is not open.
3. Once the FBW Installer opens, in the left plane, click on the radar icon (3rd icon from the top). This will bring you to the FSLTL menu where you will see two separate options for FSLTL Traffic Base Models and FSLTL Traffic Injector.
4. Click on FSLTL Traffic Injector and you should see a status of Not Running under the image header. To start the injector, click on Start to the right and you will see a command prompt window open stating that the injector has started and connected to the simulator.
5. You will be prompted if you would like to change the values for the injector. If you would like to do so, enter Y, otherwise enter N.
6. Happy flying amongst busy skies! To stop the installer, simply click Stop in the FBW Installer.

FSLTL Injector Options

On the launch of the injector, you will be presented with the ability to change various options which affect how traffic is depicted, below describes what these are and their effects.

• Live Aircraft settings, data taken from FR24 every 20 seconds.
  • Max Active IFR Aircraft - an IFR aircraft is one with both origin and destination available on FR24
    • Sets the overall amount of IFR traffic ( number is actual number of aircraft ), default gives good coverage with minimal performance impact (you can go higher but expect slowdowns!). Disable IFR flights by entering 0. This value is then proportioned to air and ground traffic based on your altitude (AGL):
      • user on the ground - 50% for air, 50% for on the ground
      • user above 10000ft - 75% for air, 25% for on the ground
      • user above 20000ft - 100% for air, 0% for on the ground
  • Max Active VFR Aircraft - a VFR aircraft is one with neither origin and destination or only one of origin or destination available on FR24
    • Sets the amount of VFR traffic ( number is actual number of aircraft ), default gives a few GA flights. NOTE: GA control is beta and not close to perfect. Disable VFR flights by entering 0.
  • Max Radius to Inject Aircraft in Air- by default aircraft in the air are injected up to 150km from the user - you can alter that distance with this option. Aircraft are removed at 10km past this distance.
  • Max Radius to Inject Aircraft on Ground- by default aircraft on the ground are injected up to 150km from the user - you can alter that distance with this option. Aircraft are removed at 10km past this distance. Reducing this radius can be useful in dense airport space like around KLAX or EGLL.
  • FlightPlannerDB API - Configures injector to represent optional realistic flight plan following. Without this API key aircraft will fly direct from origin to destination. Create an account at https://flightplandatabase.com and enter the API key from the settings page to use this feature. Optional but highly recommended.
  • Use SIDs for departure (Navigraph only) - Enables departure procedures which are determined based on the flight plan and current active origin runways based on in sim live weather METAR. Currently only available with Navigraph Navdata installed due to a bug introduced by Asobo in WU12 that can crash the sim when using the navdata api to access default navdata. The SID in use will be announced in the console window for pre-flight.
  • Use STARs for arrival (Navigraph only) - Enables arrival procedures which are determined based on the flight plan and current active destination runways based on in sim live weather METAR. Currently only available with Navigraph Navdata installed due to a bug introduced by Asobo in WU12 that can crash the sim when using the navdata api to access default navdata. The STAR in use will be announced in the console window for enroute aircraft.

• Historic Aircraft settings, data is from a historic probability distribution for airline / aircraft type at each airport.
  • Additional Airline Parked Aircraft - Sets the amount of static parked traffic at airports based on historical data for the ICAO. 0 for none, 10 for max, 2-3 recommended. ( number is scale linked to percentage of parking spots >= 10m radius )
  • Absolute Airline Parked Aircraft Max per Airport - Sets an absolute number of aircraft that will be used as additional airline parked aircraft at each airport. The number of parked aircraft will be the lesser of this value and the value the injector calculates from the Additional Parked Aircraft setting. This is useful to limit extra parked aircraft at large airports. The default is 30 (recommend) with a max setting of 100.
  • Additional GA Parked Aircraft - Sets the amount of static parked traffic at airports based on historical data for the ICAO. 0 for none, 10 for max, 2-3 recommended. ( number is scale linked to percentage of parking spots < 10m radius)
  • Absolute GA Parked Aircraft Max per Airport - Sets an absolute number of aircraft that will be used as additional parked aircraft at each airport. The number of parked aircraft will be the lesser of this value and the value the injector calculates from the Additional GA Parked Aircraft setting. This is useful to limit extra parked aircraft at large airports. The default is 15 (recommend) with a max setting of 100.

• Utility settings, these control general aspects of the aircraft injection
  • Blocked Aircraft Removal Time - a time in seconds at which to remove aircraft that should be moving but are not - this can be stuck in pushback, in taxi or just holding for too long. Recommended using 120 or 180 seconds to prevent aircraft awaiting take-off from being removed too quickly.
  • Disable showing Blank liveries - does what it says! By default, the injector will show blank liveries for models we have but currently there is no suitable livery on your machine. This option allows disabling these blank liveries from being used - so no blank liveries will be injected (GA Models excluded for now)
  • Disable showing Generic Models - does what it says! By default, the injector will show generic models if a suitable fallback cannot be found when an FSLTL model doesn't exist. This option allows disabling these generic models from being used - so no generic models will be injected.
  • Just Flight FS Traffic models - for those with Just Flight's FS Traffic installed on your machine. This setting allows you to toggle whether the FS Traffic models are given priority over the FSLTL models or not. By default FS Traffic will be below FSLTL in priority and behave like backfill in the way AIG does. If you enable this setting the role will be reversed and you will see FS Traffic's model with priority over the FSLTL version, and FSLTL will be backfill. If using this mode it is very important only the FS Traffic models are installed and the FS Traffic injection module is not active. To ensure this, we advise that only the justflight-aircraft-traffic-fleet folder be in your community folder and all other FS traffic folders be removed / disabled.

Changing FSLTL Options Manually

To update the options of FSLTL manually, browse the injector configuration file and make your alterations:

• The FSLTL Traffic Injector is located here: %APPDATA%\fsltl-trafic-injector
• Right-click on fsltl-trafficinjector-config.json and open in a text editor such as Notepad, Notepad++, or VS Code.
• Enter the values you wish to change and save the file.

To remove the prompt for changing injector options when the injector is launching, add the following line to the config file mentioned above:

• "silent":"yes"

In-Sim Running Control Options

While the injector is running, you can control a couple of aspects of its behaviour by using the inbuilt toolbar:

Reset Traffic Injection: Removes all existing aircraft and starts injecting again from scratch

Remove Nearby Traffic: Removes traffic that is active around you in an approx 5km radius - useful if aircraft are stuck in front of you on taxi or slow aircraft on final blocking your way!

The sliders allow you to update the injector settings (and have the new values written to the config file) in real-time. It can take a small amount of time until they fully update in the sim as aircraft are removed or added.

The Historic Parked setting is an exception to full real-time updates, existing parked aircraft won't be removed when you change this setting but new airports you come across will use the new setting.

Web API calls:

The injector exposes some rest API calls that allow you to trigger some of the functions of the toolbar from an external program or device.

• Reset traffic injection: http://localhost:42888/reset
• Cull nearby traffic: http://localhost:42888/nearcull
• Kill the injector process: http://localhost:42888/kill

Fallbacks for models not included in our solution and blank texture files for any airlines without livery are covered, however, you can use the FSLTL VMR alongside any custom model matching you may have or wish to use.

The FSLTL VMR file is titled FSLTL_Rules.vmr and can be found in the fsltl-traffic-base folder located in your MSFS Community folder.

Copy this file and place it in your vPilot folder. Within vPilot, add custom model matching and import the FSLTL VMR file. Order the file to the top to avoid overrides from any other VMR you may have.
