Synaptic Simulations Publishes A220 Development Update
Quick summary· AI-generated
The update details Synaptic's progress on the A220 addon, highlighting a complete Flight Management System rebuild with over 21,000 lines of code supporting lateral/vertical navigation, performance planning, and crew alerting. Systems now feed avionics from correct components (data concentration modules, electronic engine controllers), with thermal modeling that dynamically changes hydraulic, fuel, and battery temperatures based on operational conditions. Display indications include lag filters matching real-world behavior, and the FMS integrates graphical flight planning directly into the ProLine Fusion avionics for in-cockpit modification of flight plans.
Excerpt from Threshold
Synaptic Simulations recently published a thorough development update on their upcoming A220 for Microsoft Flight Simulator 2024, showcasing its systems, visuals, and intricacies.
They start the development update with a deep dive into the systems, which they intend to ensure every part of the avionics feed comes from the correct systems component, such as the synoptic pages from the data concentration modules and EICAS engine indications from the electronic engine controllers. They claim to be well on their way to achieving that goal, filling many of the “remaining holes” in their displays over the last few months.
Previously, certain features, such as a toggle for true or magnetic heading indications, flight path vector caging, and barometric/radio minimums, were missing, but they are now available through the control tuning panel. All of the indications have been routed through the proper systems to appear on the displays, as in real life.
Furthermore, the displays now indicate hydraulic, fuel, and battery temperatures, which will dynamically change based on the conditions at hand. You will be able to observe temperature changes as the hydraulic system operates, for example, as well as battery temperature oscillations based on current power draw (higher loads yielding higher temperatures).
They have also ensured that many of the system indications use lag filters to mimic real-life behavior, with a good example being switching from true to magnetic or vice versa, which takes a while to change (it smoothly moves between both). The timing is supposed to match the real counterpart one-to-one.
Their systems feature deep integration with the simulated world, including physics and wind-based control surface reactions, with depressurized hydraulic systems deflecting under gravity and strong winds.
Their Flight Management System was entirely rewritten from scratch since the last FSExpo (2025), providing a more stable, scalable, and more sustainable foundation for the features the airplane offers. In over 21,000 lines of code, they have built a majority of the Flight Management System features, including graphical fuel planning, full lateral and vertical navigation, performance planning, crew alerting and messaging, vertical direct-tos, configurable holds, and path offsets.
The graphical flight planning system is deeply integrated into the ProLine Fusion avionics of the A220, allowing the pilot to make modifications to their flight plan…
