Synaptic Simulations has shared a brief end-of-year development update on its upcoming A220, offering a snapshot of where the project stands as it heads into 2026.

Over the past year, the team has made steady progress across the aircraft’s core systems, including engine control, fly-by-wire, and autoflight logic, as well as a significant rebuild of the flight management system, to support deeper system integration. 

System complexity has continued to grow, with the EICAS now featuring more than 100 messages. At the same time, ongoing revisions to both the engine and flight models aim to further refine the aircraft’s handling and performance. 

Looking ahead, Synaptic says testing will ramp up in the coming months, with a focus on LNAV behaviour across global procedures, VNAV integration, and ensuring that performance data is adequately respected by guidance and engine systems. A handful of remaining systems, including pressurisation and autobrakes, are still being finalised. 

While the A220 did not release in 2025, the team reiterated that the extra time is being used to deliver a more complete, polished product, with further updates expected, as development continues into the new year.
