iniBuilds A350 Airliner for Microsoft Flight Simulator 2024 & 2020 v1.2.7 Released

iniBuilds A350 Airliner V1.2.7 Update 🚀

Ahead of the full changelog, we wanted to share some of the key improvements the team has been working on for A350 v1.2.7. This update is one of our most substantial rounds of refinement yet, with a major focus on VNAV and LNAV accuracy, the flight model and handling characteristics, and overall performance. Alongside these core improvements, you’ll also find a wide range of fixes and enhancements across the FMS, flight deck systems, OIS, visuals and sound. Full details on every change can be found in the complete changelog below.

This update can be downloaded via the iniManager.

Key Improvements

Improved Stability & Crash Reporting

We’ve resolved several FMS-related crashes and stutters, and added optional automatic crash reporting, similar to the A380. This gives the team much greater visibility into rare and flight-specific issues that are difficult to reproduce internally, allowing us to track down their causes and deliver fixes more effectively.

On first launch of v1.2.7, you’ll be presented with a consent form on the FMS screen. You can reset your consent at any time via a toggle on the OIS Options page, with changes taking effect from your next free-flight session in any variant.

Refined LNAV

LNAV has received a substantial overhaul, with improvements to both the route presentation on the navigation displays and the underlying guidance the aircraft uses to fly it. Turn anticipation, transitions, displayed path geometry and aircraft tracking have all been refined together, bringing the drawn flight path and the aircraft’s behaviour into much closer agreement. The result is more accurate, consistent and predictable route tracking throughout the flight, with improved route drawing across departures, arrivals, approaches and missed approaches, and more reliable DIR TO, abeam waypoint, offset and waypoint sequencing behaviour.

Improved VNAV

Descent predictions are now substantially more accurate, with altitude and speed constraints correctly respected throughout the climb, cruise and descent phases. We’ve smoothed out constraint sequencing, eliminating the thrust oscillation and level-off/level-on behaviour previously seen when approaching waypoints with restrictions. DECEL point calculation after a DIR TO has been improved, managed speed targets should no longer flicker or jump erratically, and the level-off arrow on the ND now reliably reflects the aircraft’s predicted flight path. We’ve also improved the handling of holding pattern constraints, fixed the vertical profile latch so it correctly prioritises the descent path over speed, and resolved cases where hard altitude constraints at the FAF were being disregarded. Together, these changes make the vertical profile far more consistent with what’s shown on the ND, VSD and PFD, and bring the aircraft’s behaviour closer to the expected profile.

A note on LNAV & VNAV:

Both areas have seen a significant amount of focused development and testing in this update, covering a wide range of previously reported scenarios across SIDs, STARs, approaches, missed approaches and holding patterns. That said, given the sheer number of possible route and procedure combinations, there may still be edge cases that need further refinement. We’ll continue to monitor your feedback and reports closely, with further LNAV and VNAV improvements already planned for the upcoming A350 v2 update.

Enhanced Flight Model & Handling Characteristics

We’ve made targeted improvements to roll and pitch axis sensitivity, giving a more natural and predictable control response across the flight envelope. We’ve also resolved the issue where the aircraft would slowly roll further into a bank after being rolled to 22° and released, improving stability and trim behaviour in manual flight. Alongside these handling refinements, ground spoiler deflection angles and extension rates have been corrected to properly reflect the different deployment behaviour of spoilers 1-2 versus 3-7, bringing landing and rejected takeoff performance more in line with the real aircraft. Autoland behaviour has also been improved, resolving the oscillations and inconsistencies previously seen when landing in weather with a significant tailwind component.

Performance Optimisations

We’ve expanded the Performance Mode toggle logic, bringing the same approach used on the A380 to the A350, alongside several under-the-hood optimisations aimed at delivering a smoother and more consistent experience. Depending on your hardware and setup, these changes may also give a measurable boost to overall performance, particularly on systems where performance has previously been more constrained. This feature is available on the MSFS 2024 version only.

Performance Mode works the same way as on the A380 and can be enabled via the PERFORMANCE MODE toggle on the OIS Simulation Options page. When active, the cabin model, avionics bay and various other interior elements are hidden while the cockpit door is closed. Simply open the cockpit door to bring them back, and close it again to hide them.

See It in Action

Want to see these changes for yourself? You can watch all of the improvements in action in our A350 v1.2.7 showcase trailer below.

We really hope you enjoy these changes. A number of the improvements in this update have been brought forward from our ongoing A350 v2 development, and there’s plenty more still in the works for v2. We’re confident you’ll enjoy what’s coming just as much, and we look forward to sharing more with you soon!
