After WorldJetways, AirportVehicles and FollowMe, the next extension for SAM is ready to go. SAM GroundService XP places the apron vehicles in the X-Plane flight simulator.

Let the passengers deboard, connect the GPU or refuel the plane. All processes on the ground around the aircraft are simulated and displayed in 3D. From the chocks, loading or unloading of luggage or cargo, to the arrival of the cleaning staff.

As with the previous extensions, all settings can be tuned via the SAM menu. From here you can also import your flight plan from SimBrief, (as an example) or select a fast-loading option if you want it to happen a little faster.
