What is the best freeware Concorde add-on for FSX?

The best freeware FSX Concorde is our Concorde for FSX and Prepar3D package, with a virtual cockpit, functional gauges, animations, effects, flight dynamics and 18 liveries. It is an aircraft add-on, not a free standalone simulator: you need a licensed installation of Microsoft Flight Simulator X or FSX: Steam Edition.

Free Concorde flight simulator: what is free?

The Concorde aircraft package is freeware, but the simulator needed to run it is not included. Searches for a free Concorde flight simulator often blur that distinction.

• Freeware aircraft: The downloadable Concorde files are free to install and use in a supported simulator.
• FSX and FSX: Steam Edition: These are the host simulators. You need a licensed, working copy of either the boxed Microsoft Flight Simulator X or FSX: Steam Edition.
• FS2004: Microsoft Flight Simulator 2004 is a separate legacy simulator. It requires its own compatible Concorde package and a licensed installation of FS2004.
• Microsoft Flight Simulator 2020 and 2024: These use a different add-on platform. The legacy FSX and FS2004 packages discussed here are not native MSFS 2020 or MSFS 2024 aircraft, and copying them into the Community folder will not convert them.

Why is this the best freeware Concorde for FSX?

The recommended package is the strongest all-round choice because its principal aircraft components are supplied together rather than assembled from unrelated releases.

• Virtual cockpit: Concorde can be flown from a three-dimensional cockpit rather than only through external views or a basic panel.
• Functional gauges: The package includes its required cockpit instrumentation, although every supplied gauge must be installed in the correct location.
• Animations and effects: These provide a more recognisable Concorde presentation than a visual model placed over generic aircraft components.
• Flight dynamics: The configuration and flight-model files are supplied as part of the package and should be kept together.
• 18 liveries: A useful selection is included without requiring separate repaint downloads.

Freeware does not automatically mean a full engineering simulation. Do not assume that real Concorde fuel transfer, inertial navigation or centre-of-gravity procedures are reproduced in depth unless the included documentation explicitly describes them.

FSX Concorde package comparison

Choose the all-in-one FSX package for the clearest FSX experience. The older Project Mach 2 collection is mainly useful for FS2004 users or simmers who specifically want to compare that release.

The packages can coexist when their aircraft folders and configuration titles remain unique, but install and test one before adding the other. Copying an aircraft.cfg, panel or flight-model file between packages is a common cause of missing variants, broken gauges and implausible handling.

Does the Concorde add-on work in FSX: Steam Edition?

The recommended FSX Concorde should work in FSX: Steam Edition because Steam Edition retains the same basic aircraft-folder structure. Problems usually come from installing into an inactive boxed-FSX directory, nesting the aircraft folder incorrectly or omitting gauges and effects.

1. Extract the archive first. Unpack it into a temporary folder and read any supplied installation notes. Do not drag the unopened archive into FSX.
2. Locate the active Steam installation. In Steam, open the Library, view the properties for FSX: Steam Edition, select Installed Files, then use Browse. The folder Steam opens is the active FSX root; use it instead of relying on a guessed path.
3. Install the aircraft. Place the complete Concorde aircraft folder or folders under [FSX root]\SimObjects\Airplanes. The final Concorde folder must contain aircraft.cfg directly, alongside its model, panel, sound and texture folders. Remove any unnecessary outer wrapper folder.
4. Install the gauges. Merge the contents of any supplied top-level Gauges folder into [FSX root]\Gauges. Avoid creating a duplicate path such as Gauges\Gauges, and keep supplied gauge CAB files intact unless the documentation says otherwise.
5. Install the effects. Merge the supplied effect files into [FSX root]\Effects. Effects left inside the extracted download will not be found by FSX.
6. Start FSX and review security prompts. Approve a gauge or module only when it belongs to the package you deliberately installed. Declining a required module can leave cockpit instruments blank.
7. Check the aircraft selector. Enable all variations if necessary and look under the manufacturer, publisher or aircraft name defined by the package rather than assuming it will be filed under a particular operator.

The same destinations apply to boxed FSX, but its active root folder may be elsewhere. The mistake we see constantly is a correct-looking installation made into an old or unused FSX directory.

Why is Concorde missing or the cockpit blank?

A missing aircraft usually means FSX cannot find aircraft.cfg; blank instruments usually mean a gauge file, module or security approval is missing.

1. If the aircraft is absent, check folder depth. Open its folder under SimObjects\Airplanes. If another identically named folder must be opened before reaching aircraft.cfg, move the inner aircraft folder up one level.
2. If the gauges are blank, close FSX and verify the gauge installation. Confirm that every supplied gauge file or CAB reached the main Gauges folder and was not left in the archive or placed inside a second nested Gauges directory.
3. Check trusted-software prompts. A declined package gauge may not load even when its file is present. Relaunch FSX after correcting the installation and approve only the expected package components.
4. If displays or textures are black or transparent, disable DX10 Preview for a test. Some legacy FSX models, gauges and effects do not display correctly through that optional renderer.
5. If reheat, smoke or lighting effects are absent, inspect the Effects folder. Recopy the supplied effect files to [FSX root]\Effects without renaming them.
6. If handling becomes unstable, restore the original files. Reinstall the package's own aircraft.cfg and flight-model files instead of combining them with files from another Concorde release.

FS2004 Concorde

For Microsoft Flight Simulator 2004, use the older Project Mach 2 collection supplied for FS2004 and FSX. It is the appropriate alternative when FS2004 compatibility is the deciding factor.

For FSX alone, we still recommend the package above. The Project Mach 2 download is an older collection rather than the same unified combination of virtual cockpit, gauges, effects, flight dynamics and 18 liveries, so do not assume every included aircraft has an identical cockpit or feature set.

Installation in FS2004

1. Extract the collection into a temporary folder. Check its documentation and identify the folders intended for FS2004 rather than blindly copying every FSX component.
2. Locate the active FS2004 root folder. Use the installation that contains the simulator executable and its main Aircraft, Gauges and Effects directories.
3. Copy each aircraft folder separately. Place the complete Concorde aircraft folders under [FS2004 root]\Aircraft. FS2004 normally uses this directory rather than the FSX path SimObjects\Airplanes.
4. Install supporting files. Merge supplied FS2004 gauge contents into [FS2004 root]\Gauges and effect contents into [FS2004 root]\Effects.
5. Check the final folder level. Each installed aircraft folder should contain aircraft.cfg directly. An extra wrapper folder will prevent the aircraft from appearing.
6. Launch FS2004 and test one variant first. Confirm that its panel, sound and effects load before installing modifications or exchanging files between variants.

How should you prepare the first Concorde flight?

Start with the package documentation, daylight, clear weather, a long runway and a simple route. Before taxiing, identify how the package operates the nose and visor, reheat, autopilot and any custom cockpit controls it provides.

FSX can create and load a conventional route, but its planner does not reproduce Concorde-specific acceleration profiles or prove that specialised fuel, INS and centre-of-gravity procedures are modelled. Learn the supplied aircraft as documented, avoid mixing files from other Concorde packages, and leave complex weather or time acceleration until you can complete a stable take-off, climb, descent and approach.
