The time is almost here… the iniBuilds A380 Airliner will be landing next week on the Microsoft Flight Simulator Marketplace! Get ready to experience the worlds largest airliner like never before in MSFS2024!

Some previews of the 3D models at KTMB

A closer look at the upcoming iniBuilds A380 Airliner, showcasing the latest cockpit, systems & cabin lighting in action. 💡The Superjumbo is taking shape!

Today, we’re delighted to officially release iniBuilds El Hierro Airport (GCHI) for Microsoft Flight Simulator 2024!

Located on the rugged northeastern coast of El Hierro, GCHI serves as the principal air gateway to the smallest and westernmost of the Canary Islands. Surrounded by the Atlantic Ocean, dramatic volcanic terrain and steep coastal cliffs, the airport offers a truly distinctive island setting. Its exposed location, changing winds and scenic approaches make El Hierro a memorable destination for every virtual pilot.

Available now for £9.99 (excl. VAT): https://inibuilds.com/products/inibuilds-el-hierro-gchi-msfs-2024

Another week means another mini preview of the upcoming Accu-Sim Legacy RG550!

This week we are taking a look at the artwork behind the aircraft, with a little insight from our 3D lead for the project, Michal Puto, better known to us here at A2A as Mike P. Mike is a genuine artist both at the computer and away from it.

"All of the artwork for our Lancair Legacy has been created entirely in house. We have used a mixture of photogrammetry, 3D scanning, good old fashioned 3D modelling and digital sculpting, with Scott’s own Lancair Legacy providing the inspiration and real aircraft reference throughout the project.

The leatherwork inside the cockpit is a great example of the detail involved. Every leather part was hand sculpted in ZBrush before being baked onto the optimised low poly mesh used in the simulator. The textures were then created using Substance Painter and the Affinity Suite."

There is an enormous amount of work behind even the smallest details you see inside the cockpit, but it all helps us recreate the character of the real aircraft as faithfully as possible.

Beta testing continues behind the scenes, and we hope you enjoy this week’s little look at the art behind the Accu-Sim Legacy RG550!

Black Square has shipped the first update for the Commander 114, about three weeks after the aircraft launched for MSFS 2020 and 2024 on July 29. Rather than just quietly polishing rough edges, this patch reworks a core piece of how the engine behaves.

New fuel injection model — and a new way to start the engine. The Commander now runs a proper Lycoming continuous fuel injection simulation, replacing the old logic. The practical effect: starting procedure has changed. Lycoming engines don't start like the Continentals most payware GA pilots are used to — cranking with the mixture at full rich will likely flood this one. The correct method is to keep the mixture in idle cut-off while cranking, then advance it once the engine catches. If you do flood it, the fix is throttle full forward and roughly 15 seconds of cranking. In-sim checklists have been updated to match.

EDM 800 engine monitor got a real overhaul, not just a bugfix. The lean-of-peak function now properly steps through finding the leanest cylinder first, then the richest, resetting reference temperatures at each stage — giving more realistic fuel flow numbers for both max-power and economy leaning. A peak-hold display was added (hold the LF button to see the captured peak EGT/fuel flow), sample rate during peak-finding doubled to 10Hz, and the on-screen digit font was redone for legibility.

More to notice on the ground. Magneto checks are more meaningful now: each magneto drops RPM independently, subtle fouling is detectable through the drop itself (not just an obvious sound cue), and there's a new magneto timing failure with its own audio tell. Cylinder temperatures are also individually varied per aircraft rather than uniform across cylinders.

Turbocharger simulation gained manifold pressure feedback, so pushing the throttle now shows a realistic lag before manifold pressure actually climbs as the turbo spools — and a new turbo bearing failure caps how much boost you can get above ambient pressure.

MSFS 2024 quality-of-life fixes: you can now properly walk out via the wing-walk and climb back in through the pilot's seat, a couple of objects that the 2024 LOD system was aggressively culling have been corrected, and a "Show Copilot from Inside" tablet option that shouldn't have been there in 2024 has been removed.

Smaller fixes worth knowing about: a bug that could stop circuit-breaker-protected failures from triggering at all has been fixed, along with excessive solar heating of the cabin, a gear warning light that wasn't illuminating correctly, and various radio/avionics quirks (ADF acceleration, MX170 nav ident button, RNAV511 waypoint sourcing, voltage-drop audio referencing the wrong nominal voltage). The cloud strobe propeller effect is no longer a toggle — it's just on permanently now.

Version 0.1.1 is available now through Just Flight.

Synaptic Simulations has pushed out v1.0.7 of its A220 for MSFS 2020 and 2024.

The update lands alongside a bigger milestone: the A220 is no longer locked to the in-sim Marketplace and is now also purchasable through the iniBuilds Store and installable via iniManager. Anyone still running the Marketplace copy should uninstall it first before switching over.

On the changes themselves, this is mostly a systems and polish pass rather than a major feature drop:

• Localizer capture behaves more reliably now.
• Nose-wheel steering jitter has been calmed down.
• A wing-fold quirk was removed, and spoiler handle position is now properly capped.
• Several smaller FMS/PFD display fixes — an FMS preview line no longer lingers after switching to LOC, the CTP menu hides inactive items, the FCP's manual speed preselect now previews correctly for 5 seconds, and the heading pointer hides on the PFD in AUTO mode as expected.
• VHF3 no longer stays silent while in DATA mode.
• Checklist items that are latched or sensed now only latch when they're actually next in sequence.
• A datalink audio variable that was resetting incorrectly has been fixed.
• Missing contrails and the engine/APU heat-blur effect have been restored.
• Sound side got some love too: a new flap motor sound, plus reworked ground roll and touchdown audio.

iniBuilds put its long-awaited A380 through its first real test flight this week, flying Cardiff to Heathrow live on the official Microsoft Flight Simulator Twitch channel. Over roughly two hours, lead technical developer Cameron and head of production Mike walked viewers through the aircraft while flying a British Airways-liveried A380 along a route the real jet has used when repositioning after maintenance work in Cardiff.

Optimizing for a giant

Given how much airframe there is to render, performance was the topic the team spent the most time on. Their main solution: when every door is shut, the interior cabin geometry simply isn't drawn, and it only loads back in once a door is opened. There's also a dedicated no-cabin option for players who'd rather skip modeling the interior entirely. The team was upfront that this approach won't necessarily push your frame counter higher — the goal is steadier frame pacing and fewer stutters, particularly when looking around the cockpit. For a performance baseline, they're aiming to match roughly what the A350 achieves today, with further tuning planned before launch.

On consoles, an Xbox build is already being tested and reportedly holding up well, and the team confirmed ChasePlane compatibility. A PlayStation 5 version hasn't been ruled out, but iniBuilds indicated there's still work to do before that's feasible.

Built to cover multiple real-world configurations

Rather than a single fixed setup, the A380 is shipping with several swappable options:

• Cabins: the familiar Emirates four-class layout, alongside a newly revealed generic cabin meant to represent operators outside Emirates (this is what flew on stream, dressed as British Airways).
• Engines: both major real-world powerplants are modeled independently — the three-spool Rolls-Royce Trent 900, which displays N1/N2/N3 and de-rates climb thrust automatically based on aircraft weight, and the Engine Alliance GP7200, which only shows N1/N2 and relies on manually selected de-rate levels.
• Avionics: a legacy "batch 2" software standard from around 2010 sits alongside a modern "batch 7" build, and switching between them changes what you see across the FMS.

Combine all three and one purchase should be able to represent a large slice of A380s actually flying today.

Systems and features under the hood

A lot of the underlying systems architecture is shared with iniBuilds' existing A350. The EFB has been reworked to pull SimBrief flight plans, coordinate GSX ground services, and automatically factor in intersection departures when calculating takeoff numbers — no more manually trimming runway length by hand. Additional avionics include CPDLC via Hoppie, an onboard weather radar, Brake to Vacate with runway overrun protection, simulated fuel dumping, and a checklist system that can tell when an item hasn't actually been completed.

Failures can either be switched on immediately or left to occur at a random point in the flight. Beyond straightforward failures, iniBuilds also built out less predictable "situations" — things like an erratic fuel leak, vibration building on a randomly chosen engine, GPS interference, or a bird strike that knocks out an engine and leaves visible airframe damage. The ECAM system is reportedly far more elaborate than what's in iniBuilds' A320-family aircraft, with abnormal procedures running several pages deep.

Flying and taxiing the aircraft

Cameron described the flight model as effectively rebuilt from scratch for this airframe, with a fly-by-wire rotation law tuned so pilots pull back once at rotation rather than holding continuous pressure. Ground handling gets its own learning curve too: the nose gear has a capped turn rate, and — mirroring the real aircraft — the rear body gear also steers, which keeps the nose wheel from dragging sideways under the aircraft's weight. Idle thrust is enough to keep it rolling when lightly loaded, but heavier weights need a thrust nudge to get moving. At the gate, multiple jet bridges connected to the aircraft at once using iniBuilds' own jetway system.

No date yet

Beyond confirming the aircraft is coming "soon," iniBuilds didn't give a release date or price during the stream. A "Welcome to the A380" video series is planned ahead of launch, and the studio will have a presence as a platinum sponsor at the Flight Sim UK show in Bristol on October 10–11 — worth watching for any further updates.

The FSimUK event this autumn is hotting up to be a really exciting event! The first Flight Sim event in the UK since the Cosford days. Much is in the works at the moment behind the scenes, and the FSimUK team are hard at work to ensure the weekend is a success, but for us, we're just absolutely buzzing to be able to meet you and show what we've been cooking!

We'll be running presentations throughout the day so you can see just how powerful this system is, and also giving away more of our "famous" pens that seemed to be such a hit at FSExpo in June!

So come by our stand at FSimUK, meet KatiePilot & the team and try out efbX for yourself - (and get there before we run out of pens!!)

Just a little update from the team...

The good news is that our beta testing team have been hard at work and we're pleased to say that we've not come across any show stoppers for ourQ4, 2026release. Of course, beta is a fun time and it's hard to know when gremlins may appear, but based on current feedback we are confident at this stage that we are on to meet our commitments that we made earlier this summer.

The Project MAX CASA C212-200 is now available for Microsoft Flight Simulator 2020 & 2024, exclusively on iniBuilds. Our very first aircraft has officially taken flight, and we hope you'll enjoy flying the Aviocar as much as we enjoyed building it.

Thank you for following the development of this project. See you in the skies!

Development of A350 Airliner V2 is now underway, representing a much broader core upgrade rather than simply a collection of fixes or a visual refresh.

V2 includes major work across the cockpit geometry, interior and exterior artwork, aircraft variants, Head-Up Display, EFB, OIS, systems, failures and ECAM functionality. The update is being developed specifically for Microsoft Flight Simulator 2024 and will be available as a free update for all existing A350 Airliner customers.

The cockpit itself is receiving a substantial geometry overhaul based on newly collected data, giving our art team stronger reference material for revisiting the proportions, positioning and shapes of key flight-deck elements. The wider interior artwork is also being revisited to create a more cohesive and accurate cockpit environment.

Work is taking place on the exterior as well, with particular attention being given to the differences between the A350-900 and A350-1000. The wing geometry of both variants is being revisited so that each aircraft more accurately represents its individual proportions and characteristics, moving away from the more general representation currently shared between them.

The Head-Up Display is receiving a major update to its logic, symbology and behaviour throughout the different phases of flight. Our goal is to improve the accuracy of the guidance shown to the crew and ensure HUD indications respond correctly as flight modes, aircraft configuration and operating conditions change.

Both the EFB and Onboard Information System are also being revisited, with improvements planned to their functionality and integration with the wider aircraft systems. More details on the individual EFB and OIS improvements will be shared as V2 development progresses.

Another major area is the introduction of a new failure system, alongside significant updates to the underlying systems logic. This will allow failures and abnormal situations to be represented in a more detailed and structured way. The ECAM displays and associated logic are being revisited at the same time, creating a closer relationship between simulated system states, failures, alerts and the information presented to the crew.

With V2, Microsoft Flight Simulator 2024 will become the sole development platform for the A350 Airliner. Active development and updates for the MSFS 2020 version will conclude once V2 releases, although the existing 2020 version will remain available to customers in its current form. Focusing entirely on MSFS 2024 allows us to make greater use of the newer platform technology without being constrained by the previous simulator generation.

We’ve shared a new development update covering the latest progress on our upcoming A380 Airliner, with work continuing across systems, flight dynamics, ground operations, visuals and more.

A major focus has been on increasing the depth of the simulation. The A380 now features aircraft-state persistence, retaining elements such as fuel quantities, switch positions and system conditions between simulator sessions. Potable water and waste are also fully simulated and persistent, including consumption, accumulation and ground servicing. Turnarounds are further supported by our Multi-Jetway Technology, allowing multiple passenger boarding bridges to connect simultaneously at compatible airports.

The EFB and OIS have received significant development as well. Take-off performance calculations include V-speeds, FLEX temperature and stop margins, with support for intersection departures. We’ve introduced the initial NSS Avionics domain, improved chart handling, added an EFB Notification Centre and upgraded our GSX integration to V2, including dedicated notifications and a panel for monitoring ground-service operations.

Inside the flight deck, the A380 includes independent Display Unit management, a fully integrated Runway Awareness and Advisory System (RAAS) and Brake to Vacate (BTV) functionality. We’ve continued refining the fly-by-wire system and Vertical Situation Display, while the weather radar now makes use of simulator API improvements to provide adjustable tilt and azimuth. Fuel temperature is also dynamically simulated across the aircraft’s tanks and can trigger the appropriate ECAM indications when operating limits are exceeded.

The flight model has also received considerable attention. The complete landing-gear configuration is represented, including functional body-gear steering, individual gear response using MSFS 2024’s suspension modelling and additional contact points, and dedicated A380-specific fly-by-wire rotation laws. The wings use a custom dynamic wing-flex system, responding continuously to aerodynamic forces, aircraft weight, turbulence and manoeuvring loads rather than relying on a predefined animation.

Failures are being expanded through a comprehensive ATA-based failure-management system, including scenarios such as engine fuel leaks, gradual cabin pressurisation leaks and individual Display Unit failures. Events can be configured to occur immediately or randomly during a flight.

We’ve also revealed that pilots will be able to select between Early-MSN and Modern-MSN configurations, based on Batch 2 and Batch 7 standards respectively. These affect FMS capabilities, flight-guidance logic, displays, protections, procedures and checklist philosophy. Both Rolls-Royce Trent 900 and Engine Alliance GP7200 options are represented as distinct variants, with individual geometry, sounds, start and shutdown behaviour, spool dynamics, thrust response and relevant system behaviour.

Finally, exterior work continues with refined wings, engines and fuselage details, interactive Walkaround Mode elements and a range of custom Immersion FX, including water spray, engine vortices, heat blur, contrails, fuel jettison, engine fire and smoke effects, and visual effects for tail strikes.

Releasing September 1st, exclusively on the Official Marketplace on PC, Xbox Series X|S and PS5.

Take to the skies with the beautifully recreated Taylorcraft BC-12D, developed by GotFriends for Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024.

The CASA C-212 Aviocar is a pretty unusual aircraft. Originally designed as a rugged utility aircraft, the C-212 was built around a simple idea: it needed to be able to operate where larger aircraft couldn't. With its high-wing configuration, fixed landing gear, low-pressure tires, and rear cargo ramp, the Aviocar was designed for everything from short and unprepared runways to military transport and general utility operations.

We wanted to bring that character into Microsoft Flight Simulator. The result is our C212-200, developed for both Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024. Rather than treating the aircraft as simply another turboprop to fly around in, we've approached it as a complete simulation of the aircraft and its systems.

From the beginning, one of our priorities was making the C212 feel like an actual aircraft rather than a collection of visual models and simulated switches.

The cockpit has been modeled down to the individual switch level, with the various panels, instruments, and controls recreated around the real aircraft. Engine instrumentation covers torque, RPM, EGT, oil and hydraulic parameters for both engines, while the overhead panel provides access to the aircraft's electrical, hydraulic and fuel systems.

And importantly, these aren't simply switches that move because they look good. The systems behind them are designed to actually function and interact with one another.

The avionics can also be configured to represent different real-world C212 installations. Depending on the selected configuration, the aircraft can feature the classic HZ444 or EFD84 ADI/HSI, alongside different navigation equipment including GTN, GNS and KLN 90B units. A functional Bendix weather radar is also included.

One of the biggest areas of focus for the C212 has been its systems.

The electrical, hydraulic, fuel, avionics, and flight-control systems have all been developed around the real aircraft's operating logic.

The C212-200 is powered by the Garrett/AlliedSignal TPE331-10R, and the engine has received its own dedicated simulation.

The TPE331 is quite different from many of the turboprops commonly found in flight simulators. Its fixed-shaft architecture, direct Beta operation, and constant-speed propeller give it a distinct operating philosophy, and we've built the simulation around those characteristics. Starting procedures, engine response, propeller control, feathering, and power management are all modeled accordingly.

For users who want to take the simulation even further, the C212 also features an optional extended engine simulation. Engines can develop their own history over time, including wear, oil consumption, contamination, individual engine variations, and maintenance effects.

The C212-200 is also only the beginning of the C212 family within Project MAX, with the -100 already entering the development phase.

v1.1.0 of iniBuilds London Gatwick (EGKK) for MSFS 2024 has been released. This update introduces the new Multi-Jetway System at Gates 558/559, adds Taxiway Link E and updated IHPs with accompanying signage, and improves taxiway pathing and offset-threshold behaviour for ATC and AI traffic.

This update can be downloaded via the iniManager.

v1.1.0

• Added multi jetway system [Gate 558/9]
• Added taxiway LINK E and signage
• Added new/changed IHPs (MARLO, JACKA, N2, P2, Q2, R2) and signage
• Taxiway paths have been decluttered to help with ATC/AI pathing
• Taxiway/runway entries on offset thresholds should now show correct behaviour

Parallel 42 has completed the rollout of ChasePlane's latest update for Microsoft Flight Simulator 2024. The update, version 2026.33.5.14, releases the new "Spotting" feature to all users.

• Added a new Plane Spotting experience with live nearby traffic, traffic filters, better aircraft names, aircraft details, runway information, flight phases, sizes, speeds, distances, traffic counts, and quick actions to view or track another aircraft.
• Spotting is a new experience that puts nearby traffic front and center, including aircraft from AI traffic packs, supported online networks such as Vatsim, IVAO, and SayIntentions. Native Microsoft Flight Simulator multiplayer aircraft are not supported due to platform limitations.
• Added automatic traffic spotting, so ChasePlane can help pick an interesting nearby aircraft, keep the camera focused on it, and adjust the view more smoothly while tracking traffic.
• Added richer world and airport camera lists with runways, gates, parking spots, airport viewpoints, more airport camera locations, and clearer grouping at large airports.

G'day Pilots!

Today we are incredibly excited to be announcing the upcoming release of our Spitfire 'V2' module, which has been completely rebuilt from the ground up for MSFS 2024! This isn’t a small update or conversion of our 2020 Spitfire. We’ve started from scratch, taking full advantage of the amazing new developer tools and features available in MSFS 2024 to create the best Spitfire simulation we possibly can.

The package will include multiple variants of the Spitfire, including:

• The iconic Mk.IX - complete with elliptical and clipped wing versions of the C and E wings, as well as the broad chord and standard chord rudder.
• The Mk.VIII - featuring a retractable tail gear, shortened ailerons, an altered cockpit layout and the unique Standard Beam Approach (SBA).
• The Mk.XVI - equipped with the lowback/"rear-view" fuselage, pilot friendly bubble canopy and gyro gunsight.
• The Mk.IXc floatplane - an experimental variant created for maritime operations and equipped with floats and a modified tail.

We have gone to great lengths to capture every rivet, sound, and system with the greatest amount of detail possible. Our goal is to create the most realistic and immersive Spitfire on the market! Key features include:

• Completely new 3D art featuring some of our finest work to date.
• Full sound overhaul to create our most dynamic and immersive soundscape yet.
• A full suite of Visual Effects - see the intense flames, smoke, pops and puffs of the Merlin engine.
