What are the best airport scenery add-ons for FSX?

Adam McEnroe
In short

Compare the best FSX airport scenery add-ons for KLAX, Heathrow, Barcelona and Ireland, with installation, compatibility and conflict advice.

The best airport scenery add-ons for FSX and FSX: Steam Edition are focused upgrades for airports you use often: Los Angeles V3 for KLAX, Heathrow Terminal 5, Barcelona El Prat, and an Irish airports collection. Choose a full rebuild for hub operations or a regional pack for broader touring coverage.

Our best FSX airport scenery add-ons

These freeware picks from our Fly Away Simulation library cover four distinct needs: a major US hub, a focused terminal enhancement, an improved European airport and broad regional coverage.

Scenery add-onBest forWhat it changesMain caveat
Detailed KLAX rebuild with photoreal groundUS airline and long-haul operationsRedesigned terminals, the Tom Bradley International Terminal, ground textures and A380 parking.Dense AI traffic and other Los Angeles scenery can increase the total performance load or create duplicates.
Terminal 5-focused Heathrow enhancementFlights using Heathrow Terminal 5Terminal 5A, 5B and 5C buildings, the control tower and HSBC-branded jetways.It enhances one part of EGLL rather than rebuilding the entire airport.
Improved default Barcelona El Prat airportEuropean airline routesSharper ground detail, a better apron layout and revised airport data compared with default FSX.The layout may represent a different period from the charts or aircraft navigation data you use.
Multi-airport Irish scenery collectionRegional touring and general aviationUpgraded airports plus numerous smaller Irish aerodromes.Check the documentation for included locations and disable any separate rendition of the same airport.

Heathrow Terminal 5 is the right choice only if that part of EGLL is your priority. It should not be mistaken for a complete Heathrow replacement. The Irish collection offers the opposite trade-off: less concentration on one international hub, but far more places to visit.

How do scenery add-ons improve an FSX default airport?

An FSX airport add-on can replace the airport layout, add custom buildings, improve surfaces or cover several airports, but not every package does all four.

  • Airport layout or AFCAD update: changes runways, taxiways, parking positions, frequencies and AI routing while continuing to use many default objects.
  • Focused enhancement: improves one terminal or recently altered section without replacing the whole airport.
  • Full airport rebuild: combines a revised layout with custom terminals, aprons, ground markings, lighting and airport-specific objects.
  • Regional package: upgrades several airports and aerodromes, making it the better value for touring rather than repeated hub operations.
  • Ground-texture replacement: changes the appearance of aprons, taxiways, cracks and markings at many default airports. It does not add terminals or correct individual layouts.

Across years of handling FSX uploads, a recurring mistake we see is treating every scenery add-on as a complete rebuild. Read the package description closely: an attractive terminal model does not guarantee updated runways, working AI parking or revised approaches.

Which FSX airport add-on should I choose?

Choose the package that matches your regular routes, required layout period and acceptable performance cost rather than the one with the longest feature list.

  • Choose a full rebuild when most of your flights start or finish at one hub and accurate stands, taxiways and terminal placement matter.
  • Choose a regional collection when you fly short sectors, island routes or general aviation and want several useful destinations.
  • Choose an AFCAD-style update when AI parking, taxi routing or runway use matters more than custom buildings.
  • Choose global ground textures when you want a consistent visual improvement across many default airports without installing individual replacements.
  • Check the represented period when following real-world procedures. An older airport can look excellent while retaining a closed runway, previous terminal arrangement or superseded stand numbers.

An airport package may revise local runway or ILS definitions, but it does not update a complex add-on aircraft’s FMC database or make FSX’s worldwide navigation data contemporary. If scenery and navdata represent different periods, runway identifiers and approaches can disagree.

Are Aerosoft FSX and Orbx airport packages better than freeware?

Aerosoft FSX and Orbx products are not automatically better; the right choice depends on airport coverage, compatibility, required shared libraries and how much of the surrounding region they alter.

Commercial packages may include more custom modelling, installer-managed components, seasonal assets or specialised features. Older installers can also expect boxed FSX registry entries, a particular service level or separate support software. Confirm explicit support for your FSX edition before buying or reinstalling a legacy package.

Some Orbx products cover a region rather than one airport, so they may change terrain, landclass, objects and airport elevations across a wide area. Never activate a freeware airport and a commercial rendition of the same ICAO together unless their documentation specifically says they are compatible.

Do airport scenery add-ons work in FSX: Steam Edition?

Conventional FSX scenery built from BGL and texture files generally works in both boxed FSX and FSX: Steam Edition.

The most common Steam Edition problem is an installer looking for the boxed simulator’s folder or registry entry. Do not assume the installation location. Find the actual FSX root folder used by Steam and review the package instructions before directing an installer there.

A normal self-contained manual package often uses <FSX>\Addon Scenery\Package Name\scenery, with an optional adjacent texture folder. Some add-ons also supply effects, object libraries or elevation files for other locations, so placing every file inside Addon Scenery can break the package.

How do I install a manual FSX scenery package?

Install manual scenery by preserving its folder structure and registering the folder immediately above its scenery subfolder.

  1. Extract the archive outside FSX. Read its documentation and identify any dependencies, separate elevation files or special instructions.
  2. Find the package root. If the BGL files are inside Package Name\scenery, select or copy Package Name rather than the scenery folder itself.
  3. Copy the package to a dedicated location. <FSX>\Addon Scenery is conventional, although another organised scenery folder also works when registered correctly.
  4. Add and enable it in the Scenery Library. Put the local airport above broader regional scenery affecting the same location unless the author specifies another order.
  5. Restart FSX and test the airport. Check more than the runway: inspect terminals, parking, taxiway signs, AI routing and airport elevation.

An extra folder level is a frequent cause of missing scenery. If the registered entry points to Package Name but the actual BGL files are buried under another identically named folder, FSX will not load them.

Why do FSX airports have duplicate buildings or sunken runways?

Duplicate objects and elevation faults usually mean that two versions of the airport are active or that an old correction file remains loaded elsewhere.

SymptomLikely causeWhat to check
Double terminals, runways or parkingTwo airport-definition BGLs or complete renditions are activeDisable the older add-on or duplicate AFCAD. Do not delete FSX’s core airport files.
The new airport does not appearDisabled Scenery Library entry or incorrect folder nestingConfirm that the registered package contains a direct scenery subfolder holding the BGL files.
Floating or sunken runwayConflicting mesh, airport altitude data or an old elevation correctionCheck regional packages and supplied files under locations such as Scenery\World\Scenery, where a correction may remain active even after the main airport is disabled.
Flickering ground or disappearing apronOverlapping ground polygons or an older package incompatible with FSX’s DirectX 10 PreviewDisable the competing scenery and, where the documentation does not claim DX10 support, test with DirectX 10 Preview switched off.
Black or missing buildingsMissing textures, broken folder hierarchy or an absent object libraryRestore the package from a clean archive and verify every stated dependency rather than renaming textures.
AI aircraft park incorrectlyParking sizes or airline codes do not match the AI models and traffic planConfirm that the intended airport-definition file is active; detailed terminals alone do not correct AI parking.

Change one scenery entry at a time and restart FSX after each test. Deleting unidentified BGL files makes later troubleshooting and uninstallation much harder.

How much performance do detailed FSX airports use?

There is no fixed frame-rate cost because the airport, aircraft, AI traffic, weather, surrounding scenery and FSX settings are loaded together.

At a busy hub, reduce airline AI traffic and airport vehicle density first. If performance remains poor, lower Scenery Complexity or Autogen Density one step and make sure two airport packages are not rendering simultaneously.

FSX and FSX: Steam Edition are 32-bit applications, so detailed airports also consume limited address space. A package that works alone may contribute to an out-of-memory crash when combined with a complex aircraft, dense AI, detailed weather and high-resolution regional scenery. Install one airport at a time and test it under the conditions in which you normally fly.
