Compare the best airport scenery add-ons for FSX, including KLAX, Heathrow, Barcelona and Ireland, with performance and conflict tips.
The best airport scenery add-ons for FSX and FSX: Steam Edition include upgrades for KLAX, London Heathrow, Barcelona El Prat and Ireland’s regional airfields. Choose a full airport rebuild for places you fly regularly, a regional pack for touring, or a global texture replacement when you want broader coverage with fewer airport-specific changes.
Our best FSX airport scenery picks
For most simmers, the best choice is the airport or region they actually revisit, not the package with the longest feature list.
| Add-on | Best for | What it adds | Main caveat |
|---|---|---|---|
| KLAX rebuild with photoreal ground textures | US airline and long-haul operations | Redesigned terminals, updated aprons, lighting, parking positions and A380 gates. | AI traffic and other detailed Los Angeles scenery can increase the total performance load. |
| focused Terminal 5 enhancement at Heathrow | Heathrow departures and arrivals using Terminal 5 | Terminal 5A, 5B and 5C buildings, the control tower and realistic HSBC jetways. | This concentrates on Terminal 5 rather than rebuilding every part of Heathrow. |
| Barcelona El Prat international-airport upgrade | European airline routes | An alternative to the sparse default FSX representation of this major Spanish airport. | Check the included layout against the charts and navigation data period used for your flight. |
| regional Irish airports and aerodromes collection | Regional flying, island touring and general aviation | A broad package covering upgraded Irish airports and smaller aerodromes. | Read the package notes for the exact included locations rather than assuming every Irish airfield is covered. |
A global airport-ground texture replacement is the better choice when you want sharper taxiways, aprons, markings, cracks and weathering across many default airports. It improves surfaces, but it does not add terminals, correct parking positions or update runway layouts.
Which FSX airport add-on should I choose?
Choose according to route coverage, layout accuracy and performance rather than screenshots alone.
- For regular hub operations: install the complete airport upgrade for the hub you use most. Detailed terminals and accurate stands matter when almost every flight begins or ends there.
- For regional touring: a multi-airport collection offers more useful coverage than spending the same storage and performance budget on one large hub.
- For worldwide default airports: use a ground-texture upgrade. It provides consistent visual improvement without replacing hundreds of individual airport layouts.
- For present-day procedures: inspect the scenery’s runway, taxiway and parking layout before relying on it. An older package may look much better than default FSX while still representing an earlier airport configuration.
No visual scenery package automatically updates an aircraft’s FMC navigation database. If the scenery and navdata represent different periods, runway identifiers, approaches or taxi routes may disagree.
Do airport scenery add-ons work in FSX: Steam Edition?
Standard FSX scenery made from BGL and texture files normally works in both boxed FSX and FSX: Steam Edition.
The usual problem is the installation path, not the scenery format. Older installers may look for a boxed FSX folder even when Steam Edition is installed elsewhere. For a conventional self-contained package, the structure is normally <FSX>\Addon Scenery\Package Name\scenery with an optional adjacent texture folder, but always preserve the structure specified by the included instructions.
Do not point every installer blindly at Addon Scenery. Some packages also contain effects, world-elevation files or other components that belong elsewhere in the FSX installation.
Why do airport add-ons show duplicate buildings or sunken runways?
Most airport scenery faults come from two active versions of the same airport, incorrect folder nesting or a conflict with terrain and elevation files.
- Double terminals, runways or parking: disable the older add-on or duplicate airport-definition BGL, often called an AFCAD. Do not remove the simulator’s core scenery files.
- The new airport does not appear: confirm that the package’s
sceneryfolder is registered and enabled. A mistake we see constantly is an extra folder level between the Scenery Library entry and the actual BGL files. - Floating or sunken runways: check for an old elevation correction or conflicting mesh. Keep the local airport and its supplied exclusions above broader regional scenery, following the package instructions where they specify a different order.
- Black or missing surfaces: restore the original texture folder from a clean archive and preserve its hierarchy. Randomly converting or renaming textures usually creates more faults.
When troubleshooting, disable conflicting scenery entries one at a time and restart FSX after each change. This is safer than deleting BGL files whose purpose is unclear.
How much performance do detailed FSX airports cost?
The performance cost depends on the airport detail, aircraft, AI traffic, weather, surrounding scenery and settings loaded together.
At large hubs, reduce airline AI traffic and airport vehicle density first. If performance remains poor, lower Scenery Complexity or Autogen Density one step and check that overlapping airport packages are not both active.
FSX is a 32-bit application, including Steam Edition, so several detailed add-ons loaded together can exhaust its available address space. An airport that works by itself may still contribute to an out-of-memory crash after a long flight with a complex aircraft, dense AI traffic and high-resolution regional scenery. Install one local airport at a time and test it in the aircraft and conditions you normally use.
