Using the default C172 (no airport/navdata addons) I can’t replicate the GS issue at the 2 provided airport, aircraft is landing safely.
SKCC RWY 16
LZIB RWY 31
What I have noticed is that the LOC is slightly off the centerline, slightly to the right.
I will not always rely on the PAPI lights, there is a dedicated report for that: PAPI and VASI lights have wrong placement, causing long landings, or are missing
And useful information from @Bishop398 you can find in this topic: Glideslopes and PAPIs are still incorrect
