Sim Update 15 Beta Release Notes - February 22, 2024


If you are playing on PC, outdated packages in your community folder may have an unexpected impact on the title’s performance and behavior.
If you suffer from stability issues or long loading times, move your community package(s) to another folder before relaunching the title.

How to install a new update safely

Known Issues

Today’s Sim Update 15 Beta build ( contains stability fixes to address sim crashes and instances of black avionics (which have been the top reported issues from the Sim Update 15 Beta). Unfortunately, while making comprehensive changes to improve these two issues, a handful of new issues were introduced: Known Issues

  • Aircraft with floats are unable to take off/land on water.
  • Reverse thrust is not functional on certain aircraft.
  • When launching a glider, releasing the winch causes the sim to crash.

While often we would not release a build to the flight groups with such obvious issues, we need community feedback on the stability fixes as soon as possible to understand if the changes were successful or if we have more work to do. The next SU15 Beta build (planned to release to the flight groups next week) will include fixes for the above three known issues. We will not release Sim Update 15 until the above known issues are fixed.

If this significantly impacts your sim experience, as a reminder, you may leave the Sim Update 15 Beta and return to the current public build at any time by following the steps outlined here: Welcome to the Sim Update 15 Beta

Thank you for understanding and participating in the Sim Update 15 Beta!

General Bug Fixes

  • Various crash fixes across the title.
  • FPS display memory usage now displays allocated virtual memory rather than used physical memory pages. This more accurately reflects the memory effectively used by the simulator
  • Fixed an issue where the model matching for AI traffic would spawn more than usual non-optimized traffic models resulting in performance and memory regression.
  • Fixed an issue that could cause a white circle to appear during gameplay
  • Improvements to reduce the probability of avionics randomly turning off on Xbox
  • Fixed some localization bugs


  • Fixed some navdata packages not correctly loaded


  • Fixed achievements for live events

Glass Cockpits

  • Changed parameters of Glass Cockpit update logic to keep refresh rate more fluid in lower framerate situations.

Garmin G3000 / G5000

  • Fixed an issue where the LNAV could compute incorrect guidance in certain situations with Low bank mode active.
  • The HSI to/from indicator now displays the correct indication while the active navigation source is FMS instead of always indicating TO.

Bug Fixes:

  • Attempting to remove or activate a flight plan leg in the MFD FPL page will now trigger a confirmation dialog.
  • The Load Approach button in the Select Approach dialog is now disabled if loading an Approach would also automatically activate the approach.
  • When opening the Select Approach dialog without an Approach already loaded/activated, the selected airport will no longer be initialized to the last airport in the flight plan unless it is also the last Waypoint overall in the flight plan.
  • Opening the Direct-To menu from the MFD FPL page will now initialize the Direct-To menu’s selected waypoint to the focused waypoint in the MFD FPL page, if one exists.

  • Fixed an issue where the PFD Bearing Information displays were not visible.
