Two runway lengths a KATL

[loop_n_roll 7]

When planning an arrival at KATL, we are given 2 runway lengths. I understand displaced thresholds for arriving aircraft, but these lengths differ by only 2 feet. Are these displaced thresholds or something else? Thanks.

Is this MSFS and the Microsoft KATL an add-on?

Looking at the MSFS data I see this too. KATL has two 10/28 runways. Most likely a bug in the scenery. Other simulators do not show this issue.
Displaced thresholds do not cause double indications and are a part of the runway length. Overrun areas are not.

Thanks. Yes it is whatever has been provided by ASOBO and Microsoft. I have no add-on KATL scenery.

I guess MSFS filters the double runways out when selecting them. Maybe a freeware scenery can help.

But I took note and will check this in LNM anyway. Maybe some old airport file is not overridden correctly. Have to see.

This is unique so far for a Microsoft airport. The add-on ("microsoft-airport-katl-atlanta/scenery/Microsoft/Atlanta/KATL-Airport.bgl") has no instruction for deleting the old runways (from "fs-base-genericairports/scenery/0302/APX25200.bgl") or I do not see it. Therefore LNM simply adds the add-on runways without removing the previous ones.

The problem is that there is nil official documentation about the BGL format. So, maybe I'm missing some parameters there. No idea.🤷‍♂️

Anyway, I did some spot checks and all other MS airport add-ons are fine.
