Synaptic Simulations

Welcome to the Synaptic Simulations A220 by iniBuilds! Join us as we explore the unique characteristics of the A220, cover the fundamentals of operating the aircraft, and take a brief look at its history and more.

Stay tuned for more A220 tutorials, setup guides, and demonstration videos as we dive deeper into this versatile airliner.

Coming soon.

On July 15, 2026, we hosted representatives from iniBuilds and Synaptic Simulations on the MSFSOfficial Twitch channel for a special preview livestream of their upcoming A220 Airliner. If you missed watching the broadcast live on Twitch, you can now watch the VOD in its entirety here on YouTube.

Fresh off FSExpo 2026, Synaptic Simulations has shared a major development update on the A220, and it's clear they're in the home stretch.

What's new:

• Systems — Avionics now pull from the correct underlying system components, including dynamic hydraulic, fuel, and battery temperature modeling. Control surfaces also react realistically to gravity and wind when hydraulics are depressurized.
• FMS Rewrite — The flight management system was rebuilt entirely from scratch (21,000+ lines of code), bringing full lateral/vertical navigation, graphical flight planning, performance planning with FLEX takeoffs and noise abatement profiles, SimBrief wind uplink, and accurate FMS quirks like the 200-leg limit and FPLN FULL messaging.
• Flight Guidance — Supports ILS, LOC, LDA, RNAV RNP, RNAV RNP AR, LPV, VOR, and VOR/DME approaches. Full autoland capability is implemented, including accurate mode transitions (RETARD, ALIGN, FLARE, ROLLOUT) and Emergency Descent Mode.
• Sounds — The iconic A220 "engine howl" is procedurally simulated based on live engine parameters, developed in collaboration with Echo 19. A dedicated sound showcase update is coming soon.

Where things stand: Most of the remaining work is bug hunting. Across all three days at FSExpo, only five new issues were found — two fixed on the spot — with zero crashes. A release trailer also dropped last week.

No release date announced yet, but it's clearly very close. Full update: iniBuilds Forum

Synaptic Simulations confirmed its presence at FSExpo 2026, where attendees can experience the A220 project firsthand and discuss development progress with the team. The development team continues to state that release remains planned for 2026 while prioritizing quality and system completeness.
