185th VFS SOP 2 - BMS 4.34 Installation & Setup SOP

As of May 2020, the 185th VFS fly install standard BMS 4.34 Update 4.


Installation of BMS 4.34 is fairly straightforward. It works fine with Windows 10, 8 & 7 and with both NVIDIA and AMD graphics cards.

You will need Falcon 4.0 installed, and BMS 4.34.0 and Updates. If you don't already own a copy of Falcon 4.0, it can be purchased from GOG for a very low price. Once you have Falcon 4.0, install it. There is no need to run Falcon 4.0 but you must keep it installed on your computer to install and run BMS 4.34.

Once you have download the BMS Installer and updates and have Falcon 4 installed, simply extract the Falcon BMS 4.34 Setup folder to your chosen drive, run Setup.exe in the Setup folder and follow the instructions. Then extract each update into the BMS Setup folder, run and install sequentially. For more detailed install instructions see Pages 3-12 to 3-18 of the BMS Manual Change 2.0.

It is recommended that you only copy your logbook across from 4.33 but the official list of files that can be copied is on Page 3-17 of the BMS Manual. Do not copy across any files other than those listed as it will cause issues in BMS 4.34.

Falcon BMS Config file Setup

Once BMS is installed, you will need to edit your Falcon bms.cfg file. Ensure the following lines in your Falcon bms.cfg file (...\Falcon BMS 4.34\User\Config):

Ensure you take a backup copy of the default config file so you can revert to this if required.

set g_bPlayIntroMovie 0
If this is set to 1 change it to zero to avoid the intro movie playing every time you launch BMS.

g_bCalibrationHg 1
Sets atmospheric pressure cockpit altimeter units to Imperial (inHg).

set g_bHiResTextures 1
Enables hi-res textures.

set g_bNoAAAEventRecords 0
Change the default value of 0 to 1 (Removes recording of AAA in debrief file, otherwise these will clog up your debrief)

set g_bPrettyScreenShot 0
Change the default value of 0 to 1 (Removes any text from screenshots you take)

set g_nTaxiLaunchTime 7
Changes the default time before taxi time when entering the pit from 4 to 7 minutes when commiting to taxi.

set g_nminimum_available_aircraft 8
Set the minimum number of fraggable aircraft in Sqn to 8 to prevent low aircraft availability from stopping you fragging a mission.

g_bRampTaxiStart 1
Committing to taxi spawns on ramp instead of taxiway. It is important that everyone selects this Option to 1 otherwise the flights will spawn in different places.

You should not make any other changes to the config file.

In your IVC.ini file located in ..\Falcon BMS 4.34\Bin\x86\IVC folder, make the following changes:

Ensure you take a backup copy of the default ini file so you can revert to this if required.

#quick = 0
quick = 1
this will enable HAVE QUICK ambient noise of UHF that simulates frequency hopping anti-jam capability

#hum-level = 0
hum-level = -18
400Hz tone you hear that simulates leak of AC power hum into the audio feed to your ears

#hiss-level = 0
hiss-level = -18

Remarks - ambient noise in the incoming transmission in hissing form

#uhf = 307300
uhf = 339750

#vhf = 1234
vhf = 1234

#outsiders = seat
outsiders = all

Alternate Launcher

There is a 3rd party alternate launcher available for BMS that allows HOTAS setup from the launcher. It is available to download here. See launcher documentation for details. Some members have experienced issues with key bindings dropping out using the Alternative Launcher. If you do encounter issues it is recommended that you revert back to the default launcher. It is recommended that you backup your …\bin\x86 folder before installing as the launcher overwrites some BMS default files.

Running BMS

Right click the Falcon BMS 4.34 icon on your desktop and click properties. In the Target box add the modifiers -window and -nomovie. Provided you have used the default install location, the Target box line should look like this "...\Falcon BMS 4.34\Launcher.exe" -window -nomovie It is highly recommended that you run BMS in windowed mode others you can get CTDs, especially when Alt tabbing once it has loaded.

Double-click the Falcon BMS 4.34 icon on your desktop to start the software, a ‘Launcher Window’ appears that gives you a list of menu choices to select. Select the top item on the menu, ‘Launch’. Falcon BMS 4.34 will start.

Setting Up BMS

You will now need to setup the realism, graphics, sound and HOTAS within BMS 4.34. If you're stuck ask a question in the BMS 4.34 Technical Forum. If you are a cadet and cannot access the technical forum please e-mail our Cadet Training Officer (CTO), Sabre, who will answer your query.

8. The Main Screen has several options across the top, one of which is the ‘Setup’ option. When you click this option, a ‘Setup’ Window appears that gives you access to four primary setup areas: Simulation, Sound, Graphics, and Controller.

Simulation Setup

The 185th fly with a high level of realism. Set the Skill level to Ace then ensure padlocking is set to realistic. Also, ensure ‘Smart Scaling’ ' Radio Calls Use Bullseye' and ‘Display InfoBar’ are checked. Finally, increase the ACMI file size to 500Mb then click OK. See pages 4-26 to 4-30 of the BMS manual for more details.

Sound Setup

You don't need to change the default sound settings apart from turning the Music volume down to zero but if you want to change any of these setting to suit your preferences then feel free. See pages 4-31 to 4-33 of the BMS manual for more details.

Graphics Setup

Some trial and error may be required to get the optimum balance between frame rate and eye candy. Some of the options can be controlled from your graphics card software.

For graphics setup details see Pages 4-34 to 4-38 of the BMS Manual.

Note that the Object Density sliders have now been removed and cannot be user selected. .


There are so many different combinations of controllers that it would be pointless to go into detail here. Read the BMS manual pages 4-39 to 4-52 for details. If you are struggling to resolve an issue use our BMS 4.34 Technical Forum for assistance. If you are a cadet and cannot access the technical forum please contact our CTO, Sabre, who will answer your query.

13. Installation and setup are now complete. Check out our MP SOP for details of how to setup BMS 4.34 for online flying with the 185th VFS.
