I've been consistently getting autoland touchdown rates between 500-600+ fpm in MSFS 2024 with the FBW A32NX, despite normal procedures (AP1+AP2, LAND/FLARE/RETARD sequence, thrust levers to idle at RETARD).
After several tests, I reported this issue to an FBW developer, who was able to reproduce similar results and confirmed that there appears to be an issue with A32NX autoland behavior in MSFS 2024. The issue is currently being investigated.
If anyone else is seeing unusually high autoland touchdown rates, it may be worth sharing your data in FBW Discord server.
