Set up GSX Pro for the iniBuilds A350 in MSFS 2024, install the correct profile, synchronise doors and loading, and fix stuck services.
To set up GSX Pro with the iniBuilds A350 in Microsoft Flight Simulator 2024, update GSX and the aircraft, load a compatible A350 aircraft profile, enable the A350’s GSX integration when offered, and let only one system control doors, fuel and payload. Test boarding and pushback at a large gate before flying.
This combination requires MSFS 2024 on Windows PC. GSX Pro relies on the external Couatl application, so it cannot provide these services on Xbox or PlayStation, even where the A350 itself is available.
GSX Pro and iniBuilds A350 setup
The reliable setup is to confirm that GSX works normally before changing any A350 service points or door assignments.
- Update both products. Update GSX through the FSDT installer and update the A350 through the simulator’s content system. Our GSX installation and update procedure covers the simulator target, activation and Couatl checks.
- Load the A350 at a suitable gate. Choose a stand large enough for the aircraft rather than starting on a runway or remote spawn intended for smaller types. Set the parking brake and shut down the engines.
- Confirm that GSX opens. If the GSX menu or Couatl is missing, fix that before touching the aircraft profile. An aircraft profile cannot repair an installation or simulator-link problem.
- Inspect the A350 aircraft profile. Open GSX’s aircraft configuration tool and check that the passenger doors, service doors, cargo holds, nose gear and service points line up with the model. Do not save speculative edits if the supplied configuration is already correct.
- Enable aircraft integration where available. Some A350 builds expose a GSX integration or automation option in the aircraft settings or EFB. Enable it if present. If your installed build has no such switch, use the A350 EFB to operate doors manually when GSX requests them.
- Disable duplicate ground services. Do not place the A350’s own stairs, loaders or pushback tug while GSX equipment is active. Two systems trying to control the same door or ground object commonly causes overlapping vehicles and services that never complete.
- Run a short gate test. Request boarding, verify the correct doors and cargo holds, then cancel or complete the service and test pushback. Resolve geometry and door errors before attempting a full flight.
Do I need a separate GSX profile for the A350?
Use the A350 configuration supplied by an updated GSX installation first; install a separate gsx.cfg only when the bundled profile does not recognise your aircraft variant or places equipment incorrectly.
An imported aircraft profile normally belongs under %APPDATA%\Virtuali\Airplanes\ in the exact aircraft folder supplied with the profile. It does not belong in the MSFS Community folder. Follow our aircraft and airport profile installation instructions rather than renaming folders or guessing the aircraft identifier.
A custom profile can override GSX’s built-in A350 configuration. This is a common cause of problems after an update: an old user profile remains active while GSX’s corrected internal profile is ignored. Temporarily remove or rename the custom A350 profile, restart Couatl, and retest before editing service points.
| Configuration | What it controls | Use it when |
|---|---|---|
| A350 aircraft profile | Door identities, cargo holds, vehicle positions and aircraft geometry | Equipment is wrong at every airport |
| Airport profile | Stopping position, jetway behaviour and pushback routes for a particular stand | The problem occurs only at one airport or gate |
| A350 EFB settings | Aircraft doors, internal loading, fuel and native ground equipment | GSX is waiting for the aircraft’s internal state to change |
What is the correct A350 boarding and pushback sequence?
A clean cold-and-dark turnaround prevents most GSX state conflicts.
- Prepare electrical power, the APU and the aircraft systems using the iniBuilds A350 cold-and-dark procedure.
- Set the parking brake, keep the engines shut down and use either external power or the APU as required.
- Request deboarding, catering, refuelling or boarding from GSX. If door automation is disabled, open only the doors named in the GSX message using the A350 EFB.
- Allow cargo and passenger loading to finish before changing the payload elsewhere. Avoid moving MSFS weight-and-balance sliders while the A350 or GSX is applying a load.
- Before pushback, close every passenger and cargo door, remove the A350’s native ground equipment and chocks, and ensure the APU is available.
- Request pushback from GSX. Release the parking brake and start the engines only when instructed.
The normal boarding, catering, fuelling and departure order is explained in our practical GSX service workflow.
Why does GSX keep waiting for an A350 door?
GSX waits for a door when its profile expects a different exit, the requested door has not been opened in the A350 EFB, or two automation systems are issuing conflicting commands.
- Read the door or exit named in the GSX status message, then operate that specific door from the A350 EFB.
- Check that the profile matches the loaded A350 variant. A configuration made for a different fuselage or model definition can map the wrong exit.
- If automatic door handling is enabled, do not also open and close doors manually during the same service.
- Remove any stale custom
gsx.cfg, restart Couatl and test the built-in configuration. - If GSX recognises no door-state changes at all, update GSX and the A350 before rebuilding the profile.
Why are the stairs or cargo loaders misaligned?
Misalignment at every airport points to the A350 aircraft profile; misalignment at only one stand usually points to the airport profile or parking position.
First confirm that the aircraft is stopped on the stand’s intended reference point. If every loader is offset by the same amount wherever you fly, inspect the aircraft reference position and service points. If only a particular jetway or pushback route is wrong, leave the A350 profile alone and correct or replace that airport’s profile.
The mistake we see most often is adjusting the aircraft profile to compensate for one badly configured gate. That change then breaks the aircraft at every correctly configured airport.
How should GSX and the A350 synchronise fuel and payload?
Use the A350 EFB as the source for planned fuel and payload, then let the installed GSX integration animate and monitor the corresponding ground service.
Request the GSX fuel truck and follow the on-screen instruction about when to enter or apply the target fuel. The exact sequence depends on the installed integration mode. Do not repeatedly alternate between the A350 EFB, GSX controls and the simulator’s weight-and-balance screen while loading is in progress.
Before pushback, verify the final fuel quantity, passenger or payload state and take-off mass in the aircraft. An A350 gsx.cfg fixes doors and vehicle geometry; it does not correct an inconsistent flight plan, fuel target or loadsheet.
