ILS A-220

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 Centerline

Aircraft: Synaptic A220

Simulator: Microsoft Flight Simulator 2024

Aircraft version: 1.0.5

I 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 landing

The 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.
