12 hours ago12 hr I had to write it together with GPT so as not to miss any details.Subject: ILS Localizer Tracking Issue – Aircraft Remains Significantly Left of Runway CenterlineAircraft: Synaptic A220Simulator: Microsoft Flight Simulator 2024Aircraft version: 1.0.5I have observed a recurring issue with ILS lateral guidance on approach. The glideslope (GS) works correctly and accurately. Vertical guidance is stable and behaves as expected.However, the localizer (LOC) does not appear to be tracked correctly. The aircraft remains significantly offset from the runway centerline, even though the LOC deviation indicator clearly shows that the aircraft is not aligned with the runway.The autopilot does not make the necessary lateral corrections to intercept and track the runway centerline. Manual intervention is required to disconnect the autopilot and turn the aircraft onto the runway centerline.This has occurred on more than one flight/airport, so it does not appear to be an isolated event.Example:- Airport: Almaty (UAAA)- Runway: 05R- ILS approach- GS captured and tracked correctly- LOC deviation was clearly visible- Aircraft remained approximately 500 m left of the runway centerline on final- Autopilot did not correct the lateral deviation- Manual takeover and heading correction were required to complete the landingThe attached screenshot shows the aircraft position relative to the runway centerline. The red arrows have been added for clarity. The vertical ILS guidance appears to be working normally; the problem seems to be specifically related to lateral/localizer tracking. I have previously observed similar behavior on another ILS approach, so the issue appears to be reproducible. Please investigate the LOC capture/tracking logic and lateral autopilot guidance.

It can struggle to properly track the LOC until you reach the FAF (Final Approach Fix).I hope this explanation helps! If you still feel like you’re experiencing issues, you can always check the Synaptic Discord, where they may be able to provide further troubleshooting assistance.Thanks!

I’ve read that many real world pilots will often request an RNAV approach based on the LOC behavior! Kyle - Community Manager iniBuilds Ltd. | inibuilds.com
