Testing instructions

1. Select an ILS approach/tune ILS frequency in the MCDU.
2. press LOC or APPR on the FCU such that LOC or LOC/G/S arm or activate. Verify purple ILS appears on the bottom right of PFD without blinking.
   3.1) Deselect the LS button on either side through the EFIS control panel. Amber "LS" should appear blinking on the associated PFD side and stop after 9 seconds.
3. Once LS button is pushed on the associated side, the amber indication disappears.

Aircraft Version
Stable

Build info
"v0.12.0"
Describe the bug
When doing an ILS approach in the A380, and the LS P/B's on EFIS is not turned ON, the LS will constantly flash in amber which is correct, but doesn't automatically display the lateral and vertical deviation scales when LOC or APPR Mode is armed.

Expected behavior
If LS P/B isn't selected when doing an ILS approach, it would automatically display the LOC and G/S deviation scales on both PFD's after arming the LOC P/B or APPR P/B, and the LS P/B's would automatically light up.
Landing System Scales

Steps to reproduce
Setup an ILS approach anywhare you want and conduct approach.
leave LS P/B's off.
Check that amber LS is flashing when getting nearer to runway.
ARM LOC P/B - and check that LS deviation scales automatically appear, and LS P/B lights up on both EFIS.
Deselect LOC
Also turn off LS P/B's on both EFIS.
Check that amber LS is flashing when getting nearer to runway.
ARM APPR P/B - and check that LS deviation scales automatically appear, and LS P/B lights up on both EFIS.

For A320 it's different.

The original purpose of this PR is to just add the LS indicator on the PFD. The automatic LS selection is left for future work and should be addressed in a further PR.

Quality Assurance Trainee Report

Discord Username : Jaronics
Object of testing : #9668
Aircraft : A380X
Tier of Testing : 1
Date : 14/02/2025

Testing Process:

1. Spawned on the runway. LS was displayed in amber when spawning and didn't go away when selecting the LS buttons to on. They layered over each other. (picture attached)
2. This issue could be fixed when turning on the APP button once in the air and letting the LS buttons turn on automatically.
   2.1 Tried again, spawning at a gate. Issue still persists.
3. Armed APPROACH mode as normal and manually turned off the LS buttons. LS began to flash for 9sec.
4. Turned on the LS buttons manually. Amber LS disappeared correctly and was exchanged with the normal LS indications.

Testing Results:
Not Passed

Negatives:
Layering of the two indications on the ground needs to be looked into.

Conclusions:
PR performed as expected, except the issue when spawning in.

Thanks, I have added a fix which addresses the spawn in issue. Feel free to test it again if you'd like.
