iniBuilds has released version 1.2.3 for the A350 Airliner, delivering a comprehensive update focused on system stability, navigation logic, and overall usability for both MSFS 2020 and 2024.

Stability Fixes

The most critical fix addresses a WASM crash that could occur after selecting a STAR in the flight management system. For pilots who have experienced mid-flight crashes during approach setup, this alone makes the update essential.

Other significant systems fixes include:

  • TCAS improvements - No longer triggers from non-factor aircraft, and properly differentiates aircraft types instead of labeling everything as "HEAVY"
  • Flight Director sensitivity refinements
  • Cost Index logic corrections
  • Waypoint revision logic improvements across Active, Temporary, and Wind pages
  • Step descent logic fixes

Navigation and FMS

The flight management system receives numerous improvements:

  • Fixed STAR selection stability
  • Corrected waypoint selection for duplicates
  • Fixed Place Distance waypoint calculations with negative distances
  • Improved secondary airways logic
  • Fixed constraints and altitudes below transition level display

Art and Sound

Beyond systems, the update addresses visual and audio issues:

  • Fixed cabin window flickering
  • Corrected cabin lighting - Low, medium, and dim settings now work as intended
  • Refined RA callouts with balanced volume and attenuation
  • Improved gear extension sounds in cockpit and cabin
  • Fixed exterior sounds in MSFS 2020

Availability

The update is free for existing owners. New copies are available from the iniBuilds store for approximately 80 USD.
