GSX 4.0.19 update adds cargo realism features

FSDreamTeam released Couatl Live Update 4.0.19 for GSX on August 26, 2026, introducing new cargo handling features. Baggage and cargo trains can now perform multiple trips per hold, with the number of containers loaded adjusted to the aircraft's real hold capacity and flight specifics. Two new "load realism" settings allow users to control the amount of cargo and baggage moved during loading operations.

The update improves handling invoices by including a cargo manifest with container counts, types, and volume or weight in metric and imperial units. Aircraft profiles can now specify cargo hold capacities, and handler scripts support custom ULD configurations per airline or route. The status page and Remote API report cargo progress per hold, including train positions and trip counts.

Several fixes address vehicle routing and boarding issues, such as preventing vehicles from waiting indefinitely on taxiways or cutting through aircraft. Compatibility improvements include support for MSFS 2024's ATR 42/72 door states and fixes for handler script recursion errors that previously disrupted vehicle selection.
