Version History

Release Date: April 15, 2026
Note: This update is still in beta. “Release Candidates” are penultimate updates before the full release.
ATC
- Fixed a crash when entering a flight plan on the ATC screen (XPD-17948)
Avionics
- Fixed a crash when using a secondary monitor for avionics display, such as the G1000 PFD
Graphics Engine
- Fixed an issue where aircraft LODs (Levels of Detail) were not switching correctly with distance, causing only the highest-detail model to render at all ranges and leaving visual artifacts at maximum distance (XPD-17984)
- Graphics engine improvements, including updates to the VMA allocator and Vulkan transfer coordinator for better performance and stability (XPD-17946)
Flight Model
- Loading an in-flight situation file is now significantly more stable. Aircraft previously exhibited pitch oscillations and erratic behavior when resuming a mid-flight save (XPD-17832)
Scenery
- Nice Côte d’Azur Airport (LFMN) – improved custom airport scenery with enhanced detail and accuracy. Many thanks to Matthias Gerstberger for this update!
- Windsock indicated airspeed accuracy – windsock deflection now more accurately reflects actual wind conditions (XPD-17994)
- Updated Global Airports with the latest approved submissions from the X-Plane Gateway.
User Interface & Controls
- Fixed a crash when displaying “All Planes Altitude” in the Data Output window (XPD-17962)
- Added a dedicated pause/freeze command for Tobii Eye Tracker users (XPD-17867)
- Fixed the joystick configuration for the Honeycomb Echo Controller, as four buttons were not registering correctly and are now fully functional (XPD-17983)
