A350 Airliner V1.0.4 Update 🚀

This week's second update brings significant improvements in system depth and simulation fidelity, addressing multiple key areas. Along with some key work done in art. 

One of the most notable enhancements is dynamic fuel temperature simulation, ensuring fuel temperatures behave more realistically throughout the flight. A key improvement in this update is that fuel temperatures will no longer remain stagnant over long flights. Instead, there is now some natural dynamic variation, with fuel cooling occurring at a more realistic rate and never dropping below -20°C. Unlike older aircraft, the A350 features heated fuel tanks, primarily located within the wing box near the fuselage. These tanks absorb residual heat from the airframe and hydraulic systems, preventing excessive cooling at high altitudes.

This update can be downloaded via the iniManager.

With update 1.0.4, we’re further refining the realism of the A350’s engine behavior, specifically focusing on accurate initial spool rates. The XWB engines on the A350 don’t react instantly to thrust input. Instead, they follow a realistic, gradual spool-up process, particularly at low power settings. This update ensures the engines respond more naturally when advancing the throttles from idle, accurately reflecting FADEC-controlled ramp-up times.

Additionally, we've made a major update to the long-winglet model for the A350-900. After reviewing community feedback and conducting further investigations, we've improved the shape and profile of the long-winglet type using newly obtained technical and image reference data. This ensures a more accurate representation. Furthermore, FS20 performance has been significantly improved by optimizing node counts and refining the system for swapping cockpits. These changes reduce CPU load, resulting in smoother frame rates and fewer stutters, especially for users on lower-end systems.

All liveries will need to be re-downloaded/updated via iniManager to work with v1.0.4 for FS20 and FS24 editions of the A350 as this was a necessary step to ensure the key fixes in this patch could be carried out at once. 

Key navigation system fixes include improving waypoint insertion stability, and fixing step altitude persistence after climbs. Additionally, the wind data logic and descent speed limit functionality have been refined to better reflect real-world operations.

WASM-related fixes were also a major focus, resolving multiple crashes linked to TCAS activation, flight plan imports, and Navigraph integration. These improvements enhance stability and usability for all users.

The team remains dedicated to continuous improvement and deeper simulation accuracy, with ongoing refinements across all areas of the aircraft systems. As always, we appreciate the community's feedback and look forward to further enhancements in the future. Stay tuned for more updates as we push for even greater realism!
