iniBuilds A340 Airliner for Microsoft Flight Simulator 2024 v1.0.4 Released

[mattY]

Hello everyone!

We’re excited to bring you the A340 Airliner v1.04 update, a release that advances the aircraft in some big ways!

Over the past weeks, our teams have been WORKING to refine core systems, improving audio behaviour, and expanding functionality across the board. This update marks a major milestone for the A340 Airliner, introducing a complete rework of the EIS1 display logic, enhanced DMC behaviour, a brand-new cold and dark startup flow, and a fully featured ATSU/AOC suite that elevates the whole operational experience from pre-flight through shutdown.

There’s a lot packed into this one, so let’s dive into what’s new.

Display Unit and DMC Behaviour Overhaul
A major highlight of this update is the complete overhaul of the EIS1 display logic and several core DMC behaviours, bringing the aircraft much closer to the authentic older-generation Airbus standard.

If you’re powering up from cold and dark, you’ll spot the changes right away. Each display unit now begins with a single white diagonal line during startup, a visual cue that the screen has power but hasn’t yet begun receiving data from the DMC.

If you remember the A300, this symbol was also used when its signal generator units were manually selected off. It is another authentic carry-over from the earlier Airbus widebody lineage.

Automatic Display Reversion and E/WD Priority Logic
The Engine and Warning Display (E/WD) is one of the most important screens in the cockpit, and its priority rules are now fully simulated.

If the upper DU fails or is manually turned off, the E/WD will automatically transfer to the lower DU without any pilot action. In an electrical fault scenario, having to manually move engine indications to check status would be the last thing you want.

This logic works in reverse as well. When the upper DU comes back online, the E/WD automatically returns to it. You can test these behaviours directly through the EFB failures menu.

PFD and ND Transfer Logic
The PFD now includes full reversion logic as well. If the DU it is assigned to fails, the PFD will automatically transfer to an available display, ensuring continuous flight information is always visible. Unlike the E/WD, however, the PFD does not automatically switch back when the original screen is restored. This reflects real-world Airbus operation, where the pilot must manually use the PFD/ND transfer pushbutton to return the display to its original DU.

Single Display Unit Operation and Advisory Logic
Operating in single-DU mode introduces a unique Airbus design quirk that is now fully modeled. In normal operation, the system would automatically call up the appropriate system page and highlight it when a parameter drifts out of limits. But with only one DU available, the aircraft cannot display that page directly. Instead, Airbus uses an advisory memo (ADV) on the upper display, while the ECAM panel flashes the relevant system page light to prompt the pilot to press and hold it to view the affected parameter. After some work from the team refining this, the behaviour is now fully simulated.

Additionally, when flying with only the upper DU, page selections and the STS page require you to press and hold the button to display them. If the ECAM/ND selector is used, the system correctly reverts back to dual-operation logic.

Flight Data and Initialization Enhancements
AOC Flight Plan Uplink
The A340 Airliner now supports AOC flight plan uplinks, allowing operational flight plans to be automatically received and loaded into the aircraft. This includes route information, cost index, cruise levels, and wind data, all inserted digitally without any need for manual transcribing. The workflow from Simbrief loadsheets is fully preserved, ensuring a seamless and efficient preflight process.

Performance and Takeoff Data
Performance and takeoff data has also been improved. The aircraft now supports automatic V-speeds, flex temperature settings, and thrust rating uplinks, making preflight preparation faster and more accurate while closely reflecting real-world airline operations.

Loadsheet and Ground Operations
Digital Loadsheet Delivery
The A340 Airliner now features an updated digital loadsheet delivery. After importing from Simbrief, a preliminary loadsheet is immediately received, providing an initial overview of the flight’s payload. Once the EFB loading process is complete, a final loadsheet is automatically sent, with passenger and cargo values reflecting a realistic airline workflow from start to finish.

OCM (Operational Control Messages)
The A340 Airliner now includes updated Operational Control Message (OCM) functionality. This system handles company delay messages, diversion requests, and post-flight reports including fuel burn. It also features fully automated OOOI tracking, recording off-block, airborne, landing, and in-block times to provide an accurate overview of the flight from start to finish.

New ATC Messaging Capabilities
ATC Requests via AOC
The A340 Airliner also now offers enhanced ATC messaging capabilities through AOC integration. Pilots can send oceanic clearance requests and position reports directly from the aircraft, with all messages routed efficiently via the DCDU or MCDU. This streamlines communication and ensures procedures closely match real-world airline operations.

What This Update Means for Long Hauls
This update takes the A340 Airliner well beyond a traditional MCDU-focused workflow and turns it into a fully connected airline operations experience. Long-haul flying gets the biggest boost, with a far more procedural, automated, and immersive flow from pre-flight all the way through to shutdown.

Whether you’re running full airline SOPs, following a dispatch-style setup, or just want a more streamlined, hands-off cruise, the new ATSU and AOC systems bring a meaningful layer of depth and realism to every phase of the flight.

We hope you enjoy this update and you can check out the full changelog below!
