This is off the FlightAware radar track, not that those are reliable enough for anything but orientation:

My company has had a lot of issues with the the localizers indicating on centerline at mins and yet we're over 100 feet displaced from the centerline.

Let's wait for the ntsb report to come out before we throw daggers at our fellow brother and sisters flying the lawn dart and be thankful everyone survived with only minor injuries.

Steam or glass?

Same airplane, the 145. OP works for PDT.

Quite often I’ll elect to do an RNAV approach over an ILS. Any sort of crosswind and the plane just can’t figure it out.

Is it the AP or the instruments? Can you do better hand flying the ILS? In the CRJ I can do a better job than the AP tracking a localizer.

It's an error in the receiver of the 145 localizer when exposed to module.

I have been on the plane for over 10 years and rarely see that issue.

Agreed. 10+ years and have never seen what’s been described.

Our airplanes track the localizer very erratically. Within the service volume you can get 15-20 degree turns commanded by the FD.

If you look closely it’s the localizer deflecting a degree or two in either direction erratically. Almost as if someone is in the critical area.

I’d say in probably 5/10 of the aircraft I fly at piedmont have this issue. Some pilots prefer to fly in 195RA to tighten the system up to cat II tolerance (if that’s even a thing). I normally just intercept and fly to 3 miles outside the FAF in pink needles before switching to conventional nav.

That being said, this could be entirely apples to oranges. Who knows how our maintenance is at PDT compared to C5
