iniBuilds A350 Airliner V1.1.3 Update 🚀

Update time! The newly released v1.1.3 update delivers a variety of fixes and improvements across systems, visuals, and sounds. From Flight Management System improvements, HUD updates, and many other bug fixes that will all enhanced the A350 Airliner experience.

We also have an exciting announcement regarding sounds, which you can read all about below. Now, let’s dive into the key enhancements and fixes that are inside the v1.1.3 update!

This update can be downloaded via the iniManager.

Flight Management System (FMS) Improvements

We took some time to address a number of issues relating to the FMS logic and reworking the systems stability. These included improvements to SEC/F-PLN operation in displaying holds on the ND and handling modifications as well as an issue where FMS2 submenus would not open correctly.
We also looked at some remaining VNAV issues like crossing SPD LIMIT pseudo-waypoints not working properly in managed and selected speed modes.
LNAV also now handles sequencing after a go-around properly and correct behavior of ILS backup during non-precision approaches has been added, it no longer gets overridden by the FLS approach state.

WASM Crashes

Thanks to the support of community members, we’ve been able to reproduce and address several WASM-related crashes that were affecting specific scenarios. These included issues with custom waypoint entry and certain procedures, such as the ANF arrival into NZWP.

Identifying these edge cases can be challenging, so having clear reports and reproduction steps has been invaluable. We’re continuing to investigate similar instances to ensure greater stability going forward, and we genuinely appreciate the time and effort from those who reached out and shared detailed feedback. It plays a key role in helping us deliver long-term solutions.

HUD Improvements

The HUD has proven to be a popular feature, and we’ve taken time to focus on some key areas based on your feedback. While there’s more to come in future updates, this update includes several important improvements
We’ve corrected the chevron energy behavior to provide accurate acceleration cues, resolved an issue where “MINIMUM” indications were not appearing below decision height, and made adjustments to the HUD’s field of view and perspective for better alignment within the sim environment.

Brakes Logic

This update brings several improvements to the Brake to Vacate (BTV) system, addressing both logic and display issues.
We’ve fixed a bug where BTV would not disengage following a go-around, as well as an issue where BTV was incorrectly shown on the FMA when taxiing below 10 knots. Additionally, BTV logic now properly responds to runway exit changes, ensuring more accurate (ROT) and turnaround time calculations.

Beyond BTV, we’ve updated the overall braking system thermodynamics. This resolves cases where brake temperatures cooled unrealistically quickly during rollout, especially after overweight landings. Brake cooling is now more accurately modeled, with slower cooling rates that better reflect ambient conditions.

Other Fixes

A wide range of backend system updates have been made to improve overall realism, particularly across electrical, hydraulic, pressurisation, and braking systems. Another addition is improved engine seizure logic. Engines will now seize properly when oil runs out, adding an extra layer of realism for those flying in more challenging scenarios.

We’ve also refined the VENT and AVNCS door systems, which now directly affect cabin pressurisation. This brings more realistic depressurisation behavior, including a pressure loss of approximately 2000 feet per minute when the vent system is active.
On the electrical side, the yellow electric pump ECAM message now displays correctly when cargo doors are opened during loading or unloading. We’ve also fixed an issue where GPU availability was inconsistent on spawn, helping ensure more reliable ground power operations.

OIS Maps and Navigraph Token Logic

We have worked closely with Navigraph and the community to fix the OIS enroute map which consistently became non-functional over longer flights. Community and internal beta test team members previously able to repo this event are reporting no issue after 15+ hour flights in real time. The Navigraph authentication token issue that required users to log in periodically throughout the flight has also been resolved. We have resolved several other issues including the readout in lbs now correctly rounded.

Sounds Refinement

Several improvements have been made to enhance audio feedback and overall immersion. One fix addresses a longstanding bug where the landing gear sound would play regardless of the actual gear state, this now behaves as expected and adds to the realism during approach and rollout. We also fixed an issue where flap deployment sounds were either missing or barely audible. Now, these sounds play clearly and realistically during all flap configuration changes.

We’re excited to share that we’ve partnered with Echo 19 Audio Productions to deliver a complete sound overhaul for the A350 Airliner. This collaboration will bring a significant step forward in engine, cockpit, and environmental audio, with much greater depth and spatial detail. Work is already underway, and more updates on this will follow soon.

Exterior Lighting Improvements

Based on numerous user reports, we have improved the lighting, especially during daytime scenarios. The smaller lights such as the lights located in the wing tip assemblies will be much more visible and clearer from a distance, especially during the daytime.

Cockpit LOD Loading Bugs

For some users on lower-end PCs, or especially on Xbox consoles, the cockpit would not initially load on the highest level of detail model, or LOD, when switching the camera view from the exterior to the cockpit or on initial loading. This caused rapidly flickering displays as the LOD models were catching up to the correct level. This has now been resolved, and the displays are not flashing anymore.

Livery “Floating Decal” Bugs

Some liveries would cause floating decals towards the area in front of the aircraft. This has been resolved, you do not need to update liveries as the fix was made on the base aircraft to prevent this from occurring.

Cabin Updates

Several important issues affecting the cabins have been resolved in this update. Notably, the passenger seat belt signage is now functioning properly again.
Floor lighting is also improved, now correctly linked with the emergency exit lighting system for greater realism and safety cues.
Beyond these, we’ve implemented various smaller technical fixes that enhance the overall user experience, informed by valuable feedback from our internal testing team.

We're incredibly grateful for the consistent support on this project, we are so glad that you've appreciated the updates to improve the product in general, so you can be sure we'll continue to update this product based on user reported bugs and feedback.
