AI aircraft not appearing at airport gates in FSX? Diagnose traffic sliders, WOAI files, missing models, parking nodes, airline codes and AFCAD conflicts
AI aircraft do not appear at airport gates in FSX or FSX: Steam Edition when no scheduled flight is due there at that time, airline traffic is disabled, the required AI model is missing, or the active airport BGL has no free compatible parking. Duplicate airport files and broken taxi links can empty the gates.
What determines whether FSX puts AI aircraft at gates?
FSX populates a stand only when the schedule, traffic-density threshold, installed aircraft and airport parking data all agree. FSX and FSX: Steam Edition use the same core parking rules, although their installation paths and active scenery-library entries may differ.
- Flight plan: A compiled schedule must place an aircraft at that airport on the selected day and time. FSX does not add airliners merely to make a terminal look occupied.
- Traffic density: Each flight plan has a percentage threshold. It will not run when the Airline traffic density setting is below that threshold. General aviation traffic density controls GA flights, while Airport vehicle density does not control aeroplanes.
- Installed model: The traffic file references an exact
title=entry from an aircraft'saircraft.cfg. A missing model, renamed title or incomplete livery prevents that flight from spawning. - Parking size and type: The parking radius must accommodate the aircraft, and the stand type must be appropriate for gate, cargo, GA or military traffic.
- Parking codes: The aircraft's
atc_parking_codesandatc_parking_typesinfluence stand selection, but they cannot override an undersized, occupied or disconnected spot. - Taxi connectivity: A parking node needs a continuous route into the taxi network. A painted stand, terminal building or visible jetway does not prove that usable AI parking exists beneath it.
Which symptom identifies the likely cause?
The pattern of missing traffic usually shows whether the fault affects all FSX traffic, one add-on package or a single airport.
| Symptom | Likely cause | Check first |
|---|---|---|
| Every airport is empty | Traffic setting, inactive traffic BGL, legacy-format conflict or missing models | Airline traffic density and active traffic files |
| Only one airport has empty gates | Airport parking layout, duplicate BGL or broken taxi links | The active airport definition |
| GA aircraft appear but airliners do not | Airline slider, airline schedules or airliner models | Airline traffic density and installed AI fleets |
| Aircraft land and then disappear | No suitable free parking or no route to it | Parking radius, type, occupancy and taxi links |
| Aircraft use remote stands instead | Gate size, type or airline-code mismatch | Gate properties and aircraft parking entries |
| One airline package is missing everywhere | Missing model, incorrect title= reference or inactive schedule | The package's aircraft and traffic BGL |
How do I fix AI aircraft not appearing at airport gates?
Diagnose settings and traffic files before editing the airport, because new parking cannot create a flight that was never eligible to run.
- Raise the relevant traffic setting. Temporarily increase Airline traffic density for airliners or General aviation traffic density for GA aircraft. Give FSX a few simulator minutes to rebuild traffic after loading or changing the time.
- Try another day and time. Add-on schedules can leave an airport quiet for long periods. Test a major airport during a plausible busy period rather than assuming every gate should always contain an aircraft.
- Compare two airports. If a default major airport has traffic but the problem airport does not, concentrate on that airport's BGL and parking layout. If both are empty, investigate traffic files, settings and models first.
- Verify the AI aircraft. Check that the model is installed under the simulator's
SimObjects\Airplanesdirectory and that itsaircraft.cfgstill contains the exact title expected by the traffic file. Our model-and-traffic-file recovery checklist covers broader cases where AI aircraft have vanished throughout FSX. - Check active traffic BGLs. Traffic files are often placed in
Scenery\World\Scenery, although add-ons can use another active scenery folder. An older FS2004-format traffic BGL can cause FSX-format plans to disappear while legacy traffic remains. - Look for duplicate airport files. Two AFCAD-style BGLs for the same airport can supply conflicting parking, taxi or runway data. Disable suspected files one at a time, reload the scenery and keep backups outside every active scenery folder; simply renaming a copied file does not help if it still has a
.bglextension and remains in an active folder. - Edit the airport only after isolating it. If traffic works elsewhere and aircraft are scheduled for the problem airport, inspect the active parking nodes with an FSX-compatible airport editor such as Airport Design Editor.
Why is WOAI FSX traffic installed but not at the gates?
WOAI traffic in FSX can fail because the World of AI schedule is inactive, its aircraft model is missing, a legacy traffic BGL conflicts with other plans, or the destination airport has unsuitable parking. Raising the traffic slider will not repair a missing model or disconnected stand.
If no WOAI aircraft appear at any airport, check the installation path, exact aircraft titles and active traffic files. If WOAI aircraft work elsewhere but not at one airport, inspect that airport's schedules and parking. Older WOAI packages also commonly involve FS2004-format traffic files, so use our WOAI-specific FSX checks before changing scenery.
Why do AI aircraft land and then disappear?
An aircraft that completes its approach but vanishes after landing usually cannot find a compatible free parking spot or a valid taxi route to one. FSX removes it rather than leaving it indefinitely on a runway or taxiway.
This symptom confirms that the schedule and aircraft model are working. Check parking capacity, spot radius, parking type and taxi links, especially after installing replacement airport scenery. A more detailed terminal model can still contain fewer usable AI stands than the default airport.
How do I use ADE in FSX to repair gate parking?
Use Airport Design Editor, commonly called ADE, only after confirming that the airport definition is the fault. “AFCAD” is still widely used as shorthand for an airport facilities BGL, even when ADE rather than the original AFCAD utility created it.
- Back up the add-on airport BGL. Never overwrite the stock FSX scenery files.
- Identify the definition FSX is loading. Resolve duplicate airport files and scenery-library priority before editing, or the simulator may continue loading another version.
- Inspect each relevant parking node. Check its radius, gate or ramp type, airline codes and position. Do not make every position heavy-aircraft parking; that can place large aircraft at visually unsuitable stands.
- Check the taxi connection. Each parking node needs a valid link to the airport taxi network. Watch for isolated nodes, broken path segments and one-way arrangements that prevent an aircraft reaching or leaving the stand.
- Review spacing. Overlapping parking circles and aircraft footprints can reduce practical capacity because one occupied stand may block its neighbour.
- Compile into a separate scenery layer. Place the corrected BGL in its own active scenery folder above the airport it replaces, and disable obsolete duplicates rather than leaving several competing files active.
- Reload and test both directions. Test a scheduled departure as well as an arrival. A departing AI flight may never spawn when FSX cannot allocate suitable parking at its origin.
Do parking codes force AI aircraft to use a gate?
No. Airline parking codes are preferences, not guaranteed reservations. FSX still requires a free stand with an acceptable radius, type and taxi connection, and it may use an uncoded compatible stand when the preferred coded positions are unavailable.
Use a consistent operator code in the aircraft's atc_parking_codes entry and the airport parking spot, normally following the package's three-letter airline convention. Check radius and parking type before adding more codes. The term CodesForce is not an FSX parking parameter; if it is the name of a utility encountered in a search, it is not required to repair gate parking.
Can I fill just the gates without adding normal AI flights?
FSX has no “just the gates” traffic setting: normal AI aircraft appear according to complete flight plans and will eventually depart. Increasing airline density also adds airborne and taxiing traffic rather than permanently filling selected stands.
For aircraft that remain in place, use static scenery objects or specially designed long-ground-time schedules. Our guide to placing static aircraft at selected FSX gates explains the trade-offs. Static models do not automatically reserve an underlying AI parking node, so leaving that node active can produce overlapping aircraft.
Does a jetway prove that an FSX gate is usable?
No. A jetway is a visual scenery object, while AI parking depends on the airport facility data stored in a BGL. A gate can have a jetway but no parking node, and a valid parking spot can work without an animated jetway attaching to its aircraft.
If traffic parks correctly but the passenger bridge remains still or misses the door, that is a separate problem; see our explanation of how FSX jetways interact with AI models.
Are Stick Nodes Pro 4.3.2 APK or เนี่ย related to FSX gates?
No. Stick Nodes Pro 4.3.2 APK is an Android application-package search term, not an FSX aircraft, airport editor, scenery file or traffic utility. An APK cannot be installed into FSX or FSX: Steam Edition and will not make AI aircraft appear.
The Thai word เนี่ย is likewise not the name of an FSX setting, file format or gate-parking tool. If either term led to this page, do not copy the associated files into the simulator; the relevant FSX components are traffic BGLs, AI aircraft models and airport parking data.
