1. What is SIM ACARS?

SIM ACARS is a free ACARS (Aircraft Communication Addressing and Reporting System) report tool designed to be used for the Virtual Airlines Manager web system VAM (, it also can be used as a standalone application to track and store your own virtual flights.

The main functions and characteristics of SIM ACARS are:

  • Monitors every 100 milliseconds the main parameters of the flight.
  • Store the flight parameters into a local database every 1 minute
  • Send the flight data , parameters and events to a VAM web system


SIM ACARS is a windows application and not valid for Mac OS.

Compatible Flight Simulators:

  • FS2004 (FS9)
  • FSX
  • Prepard 3D
  • X-Plane


2. Summary Installation and Setup.


  1. Unzip to a folder of your choice
  2. No need to install - runs out of folder created
  3. Start sim acars.exe
  4. Click on the "Virtual Airline Settings" TAB
  5. Click "New Virtual Airline"
  6. Populate the 5 options available as below

            Callsign: Your ZAVxxx callsign
            Password: Your password used when registering on
            VA Name: SAVAF
            VA ICAO: ZAV
            VA ACARS URL:
            Weight Unit: Kg

       7. Once completed go to "Flight Plan" Tab
       8. At the bottom left, in the dropdown option under "Virtual Airline", you will now find SAVAF, select it


3. Installation and prerequisites

IMPORTANT: if you are using a previous version of SIM ACARS please just replace the SIM ACARS.EXE and the dll. Do not overwrite the file SIM_ACARS.DB3 otherwise you will lose your historic of flights.

SIM ACARS is a portable application, no installation process needed or required. Just unzip de folder and place it in a folder of your computer. (Program Files sub folder recommended).

Files included in the SIM ACARS:


2. 8 dll needed by the EXE

3. SIM_ACARS.DB3 is the database to store the flights, events and parameters


In the database there are more than 40.000 airports with the coordinates. This information is used by the ACARS to check the take-off and landing positions. This airport information is not encrypted. Other tables used by the ACARS to store flights, events and parameters contain the data encrypted. This encryption prevents from data manipulation and it is needed to prevent fake reports to the Virtual Airlines.

The name of the Database must be “SIM_ACARS_DB3”. You can do a backup, just copy this file and save it in a safe place.


  • Microsoft .NET Framework 4.0
  • FSUIPC for FS2004,FSX and P3D
  • XPUIPC for X-Plane


4. Instructions


2. Fill your flight plan and flight data. 

  • Aircraft Type ICAO
  • Select IFR or VFR
  • Departure ICAO
  • Departure Time
  • Cruise Speed
  • FL/Altitude
  • Passengers
  • Cargo (kgs) 
  • Arrival ICAO
  • Total EET
  • Endurance
  • Alternate 1
  • Alternate 2
  • Flight Number (CHARTER, OLM, TOUR, TFMxx Etc)


3. There are two fields that are read-only and will be automatically filled by the ACARS.


  • Aircraft
  • Registry


4. In case you want to report you flight to your Virtual Airline. During the flight the ACARS will send current information to VAM system. The user can see active flight in the current position in the web map.


  1. Select the name of the Virtual Airline.
  2. Press Login button


5. Connect to the simulator. Your simulator must be running before the following steps. Your aircraft should be in the parking position at departure airport.

  • Select the network used in your flight (IVAO, VATSIM , OFFLINE,…)
  • Select the weight units (MUST BE KG FOR SAVAF, used for fuel measure)
  • Press “Start Track”


Validations done before start the flight

  • SIM ACARS will check if the pilot is located in the departure airport
  • SIM ACARS will check if the departure and arrival airport exits in the database.


In case of any of the above validations fails a message will appear, the user can cancel to correct the data of continue, if the data is not corrected then the ACARS will detect this action as a failure.

During your flight you can see the current flight parameters and the events & failures captured. This information is displayed in the tab “Flight Data”.

The parameters captured by SIM ACARS are the following:

  • IAS (Knots)
  • Vertical Speed
  • Altitude
  • FOB - Fuel On Board: expressed in Kg or Lbs. based on the weight measure selected.
  • GS – Ground Speed (Knots)
  • Latitude
  • Longitude
  • Fuel used: expressed in Kg or Lbs. based on the weight measure selected.
  • NM To arrival
  • % Completed
  • Flaps:
    1. Flight Simulator and Prepard 3D : Flaps detent
    2. X-Plane: % of flaps extension.
  • ZFW – Zero Fuel Weight: expressed in Kg or Lbs. based on the weight measure selected.


Flight events captured:

  • Boarding (initial flight stage)
  • Taxi to the runway : when GS is > 10 Knots
  • Engine(s) start
  • Take off
  • Gear up
  • Gear down
  • Flaps movement
  • Landing
  • Engine(s) stop
  • Critical events captured:
  • Engine(s) running and beacon light OFF
  • Lights off below 10.000 ft
  • IAS > 250 Knots below 10.000 ft
  • Stall
  • Over speed
  • Pause
  • Slew
  • Aircraft changed
  • Refueling


During the landing some important parameters are captured:

  • IAS
  • Vertical Speed (ft/min)
  • G Force
  • Bank angle
  • Pitch angle
  • Lights on/off
  • Flaps position
  • Wind direction & intensity
  • Landing heading


6. When the user finish the flight the button “End Flight” must be pressed. This action saves the flight in the database.

7. Flight Summary tab visible, in this tab the user can see the flight summary.

8. If the user wants to report the flight to the VAM system: press the button “Send Report”. The flight and all the events will be stored in the VAM data base. The user can see the flight data and the map in VAM.

9. In case the user wants to start a new flight: press the button “New Flight”, this will reset all the fields, then start from the step 2.


5. Virtual Airline Settings

SIM ACARS is designed to allow pilots to report the flights to different virtual airlines. SIM ACARS does not manage any file to set-up the connection to the virtual airline web system, everything is stored in the local data base.

You can create as many VA connections as you want. Follow these steps:

1. Press the button “New Virtual Airline”

2. Fill the following information. ZAVAF VA ACARS URL: 


Your VAM user (SAVAF callsign = ZAVxxx) and password must be the same as entered in the SIM ACARS.

The user can delete any VA settings just pressing the delete icon:


6. Logbook

In the logbook tab the user can see all the flights stored in the data base.

Information about each flight is displayed if the user presses on the information icon.

In case the user wants to send the flight report to a VAM system:

1. Connect to the Virtual Airline

  1. Select the name of the Virtual Airline.
  2. Press Login button


2. Press the green icon. VAM system will not allow duplicated flights and a message will pop up in this case.


7. Flight Map

In any stage of the flight you can see your current position on six different types of maps. You can adjust the zoom with your mouse wheel.
