GSX (all versions) NEW: Ground traffic awareness. Every GSX vehicle is now aware of the space around the aircraft: the working areas other vehicles occupy — or are about to occupy — and the routes they are currently driving. This brings a whole new level of realism to how ground services move and coordinate around your aircraft, and it makes busy turnarounds both better looking and better behaved.
No more vehicles inside each other. A vehicle no longer drives in while another one is standing on its working spot: it waits for the area to actually clear, then approaches. This works automatically with every fuelling strategy, custom approach path and custom stop position — GSX derives each vehicle’s real footprint from where it is actually going to park, articulated vehicles included: a baggage train is tracked wagon by wagon, a fuel tanker as cab and trailer.
Vehicles yield to each other on the move. Moving vehicles see each other’s routes and give way: they slow down, wait for crossing traffic, and follow consistent right-of-way rules designed so that two vehicles can never end up waiting on each other forever. A departing truck whose exit runs past a vehicle still working — the classic case of the fuel truck leaving through the catering position — now holds until the way is physically clear, and moves on the very moment it is. Vehicles only ever adjust their timing, never their route: custom approach and leave paths are always driven exactly as you authored them.
Faster turnarounds, not slower. The new system replaces the old fixed safety timers and one-size-fits-all rules with real geometry, so services start as soon as the space is genuinely free: catering no longer waits a fixed time after refueling, the water and lavatory trucks angle their approach at their service port so they stay clear of the rear stairs, the catering truck and each other, the empty baggage trains leave immediately when boarding starts instead of lingering in the way, and the two catering trucks now leave independently of each other. And whenever something is waiting, the status page tells you exactly why — “waiting for the Fuel truck to clear the work area” — on the in-game panel, the web remote and the EFB alike.

GSX (all versions) NEW: More services at the same time. The zone-based system has allowed us to remove most of the arbitrary restrictions on which services could be performed together: instead of blanket rules keeping whole services apart “just in case”, services now run concurrently whenever there is actually room for them — and only wait when there genuinely isn’t. You can now call Catering, Refueling and Boarding all at the same time and watch the whole turnaround unfold at once — the fuel truck at the wing, both catering trucks at their doors, stairs, buses and baggage trains all working together, each vehicle taking its spot the moment it’s actually free, just like on a real apron. This also makes the “Assistance services Auto Mode” option considerably more useful: when it chains Refueling and Catering into a Boarding request, those services now genuinely overlap instead of queueing one after the other, with the baggage loaders dispatched as soon as the trucks have taken their working positions — shorter, livelier and more realistic turnarounds without touching a single menu.

GSX (all versions) NEW: Smoother vehicle and passenger movement. The most time-critical animation code has been moved from Python to C++, greatly reducing latency: the position of every ground vehicle — articulated ones included, so the baggage train’s whole wagon chain, the fuel tanker’s trailer, the towed GPU cart and everything they carry — and of every walking passenger and crew member is now updated by the engine’s native code on every single frame. Ground traffic keeps moving fluidly even in the busiest moments, greatly reducing the micro-stutter in vehicle and passenger motion that could be seen during heavy scenes at large airports.

GSX (all versions) NEW: Print your invoices on a real receipt printer. If you have one of the inexpensive thermal POS receipt printers (58 mm or 80 mm paper rolls, ESC/POS compatible — the kind shops use for till receipts), GSX can now print every invoice as a genuine paper receipt: operator logo letterhead, itemised charges with local currency, taxes and totals, finished with an automatic paper cut.
Zero-configuration setup. The new “Invoice printing” section in Settings > Network detects receipt printers automatically — the paper width is read from the printer itself and the receipt layout adapts to 58 mm or 80 mm rolls — with a Print test button to try it out. Regular full-size printers are deliberately not used: for those, the invoice’s “Open in browser” option and your browser’s print function already give the best result.
Preview first, print from anywhere. Before printing you get a preview of the exact receipt, character for character, right in the GSX menu — and the whole flow works identically from the in-game panel, the web remote and the EFB, from both the invoice notification and the “View past invoices” browser (your previously saved invoices are printable too).
Auto Print. An optional setting (off by default) prints every new invoice automatically the moment it is issued — receipts simply roll out of the printer as services complete, no clicks needed. A lovely touch for home-cockpit setups.

GSX Pro Change: Remote API updates for third-party developers. A remote client — an EFB, an ATC or dispatch tool — can now select the parking gate directly with a single command, picking from the same live gate list the protocol already publishes. And beyond reading the rich aircraft, gate and flight data that aircraft profiles (handler scripts) see, remote clients can now also write the same properties a handler script can customize — gate options, service positions and routing — so external tools and aircraft integrations can adjust GSX behaviour on the fly. Both features are fully documented in the included Remote API guide.
-
GSX (all versions) Change: On multi-aircraft (MARS) parkings, custom vehicle approach paths are now strictly per sub-position: paths authored on the parent position no longer apply to its sub-positions — a path is only geometrically correct for the exact stop position it was authored on — and editing a sub-position’s paths can no longer silently modify its siblings.
-
GSX (all versions) Fix: Invoices for ground handling and passenger transport now show the amounts converted to the airport’s local currency, exactly like the fuel and catering invoices already did.
-
GSX Pro Fix: Service questions (“Do you want to board the crew?” and similar) now reliably appear on the web remote and the EFB while the main in-game menu is closed. Previously they could be silently skipped, depending on how the menu had been used earlier in the session.
-
GSX Pro Fix: Menus displayed in the classic style now render correctly on the web remote and the EFB — they could show up empty, or with leftover buttons from a previous page.
-
GSX Pro Fix: Fixed the EFB occasionally being left with blank menu icons after quickly backing out of the SimBrief details pages.
-
GSX (all versions) Fix: Fixed a possible complete freeze of the Couatl engine when a menu (the refueling fuel-level selection, for example) was re-displayed while the menu system was busy closing.
-
GSX (all versions) Fix: The SimBrief entry in Additional Services opens its details pages again.
-
GSX (all versions) Fix: Much improved walking routes for passengers moving between the aircraft stairs and the passenger bus: passengers now step clear of the bus before heading for the stairs, walk around the passenger-guidance unit instead of through it, and on aircraft without one they no longer detour in single file all the way out to the wingtip — each door keeps its own separate stream, rounding the nearest wing edge only when actually needed.
-
GSX (all versions) Fix: The arriving baggage train could reverse onto its docking spot and end up folded against itself, misaligned with the aircraft; it now docks straight every time, on custom and default routes alike.
-
GSX (all versions) Fix: The empty baggage train waiting at the gate could materialise with the tractor and all its wagons stacked on a single point; every part now appears correctly spread out.
-
GSX (all versions) Fix: The fuel truck’s fuel counter could get stuck showing 00000 for the entire refuel, and the scrolling fuel-price display could stop with an error; both now display reliably.
-
GSX (all versions) Fix: Long invoices shown in the in-game panel now shrink the operator logo to a small inline mark instead of hiding it entirely.
-
GSX (all versions) Fix: Fixed an internal conflict that could disable the automatic removal of pre-existing static vehicles at the parking spot.
-
GSX (all versions) Fix: Improved engine resilience: an error occurring in the per-frame animation code is now caught, logged and isolated to the object that caused it, instead of potentially corrupting the engine and causing a crash much later.
