GSX v.3.8.8 out

Version 3.8.8 April 1st, 2026

GSX Pro NEW: Handler scripts: avirampExits property allows aircraft handlers to control which passenger exits use aviramp staircases on a per-exit basis.

GSX (all versions) Change: Airport customization dialog: waypoint labels clarified to "Rear Stairs waypoints" (on jetway gates), "Passengers waypoints" (on non-jetway gates), "Static Jetway waypoints", and "Airport Walkers waypoints".

GSX Pro Fix: Crash when aviramp is enabled in the airport profile but no aviramp stair model is installed. GSX now falls back to a normal staircase gracefully.

GSX (all versions) Fix: Crash with MARS sub-positions on airports that have jetway-connected parking spots, caused by an unpickable C++ object in the parking snapshot.

GSX (all versions) Fix: MARS sub-position pushback labels could bleed into the parent parking after restoring the original gate.

GSX (all versions) Fix: Jetway waypoints in the airport customization dialog were only editable when "Simultaneous Jetway + Rear Stairs" was enabled. They are now always available on jetway gates.

GSX (all versions) Fix: Boarding would wait for manually operated stairs to complete their full retract cycle before proceeding, even if the stairs were already extended and in position.

GSX (all versions) Fix: Pushback crash on routes with a pull-push direction change (e.g. pull-push-pull), where the steering wheel tracking was not reinitialized on the push segment.

GSX (all versions) Fix: Crash during boarding or deboarding on aircraft with embedded stairs but no GSX stair model, caused by a missing attribute on the embedded stair object.

GSX (all versions) Fix: Cargo loading LVars (FSDT_GSX_LOADER_EXIT) were incorrectly reset by the first loader to finish, clearing the state of other loaders still active.

GSX (all versions) Fix: Global cargo progress LVars (FSDT_GSX_BOARDING_CARGO_PERCENT, FSDT_GSX_DEBOARDING_CARGO_PERCENT) could reset to zero prematurely when one loader finished before another.

GSX (all versions) Fix: Crew and pilot boarding/deboarding LVars (NOT_BOARDING, NOT_DEBOARDING) set by addons were overwritten when boarding or deboarding started.

GSX (all versions) Fix: Crash with FSS E-Jets when checking economy class while a background tasklet was still running after disengage.

GSX (all versions) Fix: Handler script super calls could permanently clear internal handler state, causing crashes in subsequent stock handler methods such as PIGS creation.

GSX Pro Fix: Leonardo Maddog: GSX external stairs no longer appear on the rear exit when the hydraulic press is not activated.
