Describe the bug

When performing a CAT 3 DUAL landing, the plane suddenly veers to the left. This has happened twice, both during KJFK's 22L ILS approach.

Expected behavior

The plane follows the localiser, and touches down.

Steps to reproduce

1. Fly the KJFK ILS approach (22L)
2. Enable both APs (DUAL approach)

Do you have the calculated ILS option on or off in the flypad? Do you have any third party scenery or navdata?

[yourlunch321]

i'll go check that

[yourlunch321]

calculated ILS is off, i have navigraph 2503

[tracernz]

Does it work okay without Navigraph? The ILS indication comes from the sim here and depends on the navdata, so not something we control.

[yourlunch321]

i'll go check. i just turned on calculated ILS, i'll see if that does anything too

[tracernz]

I would recommend keeping that off; I was going to suggest turning it off if you had it on.

[yourlunch321]

oh, calculated ILS actually fixed the issue.

[becas22]

The ILS identifier changed from IIWY (RWY22L) to IHIQ (RWY04L) (frequency is the same). This could be a navdata problem.

With the calculated ILS on, do the ILS ident change?

[yourlunch321]

with calculated ILS on, the ident doesnt change. however, i turned calculated ILS back off, and the bug happened 1/5 times. weird. i'll wait for navigraph 2504 and see if it hopefully fixed this issue.
