Vaziani 31 ILS localizer incorrect

[Nealius]

Today I flew some IFR cross-country in the Viper: Vaziani-->Senaki-->Vaziani. ILS worked perfect at Senaki, but it was FUBAR at Vaziani with the localizer going all over the place.

 

In the Viper, VAS 22X ILS 108.75 CRS 310 for Runway 31.

 

In TCN mode I get this, with the CRS Deviation to the left:

 

In PLS/TCN mode I get this, with the CRS Deviation on the extreme opposite:

 

Here, you can see the runway to my left, above the Master Caution brow light, but the localizer bar is telling me I need to turn right.

 

I circled around for a "visual" landing, and the localizer bar did not show centerline until I crossed the threshold. The glideslope bar is also stuck at the bottom.

As ILS was working at Senaki (RWY 09) i.e. zero wind or +6 knot from the west, are you sure RWY 31 was the active runway at Vaziani.

 

What was the ground wind's strength and direction at Vaziani (ATC ILS directions are unreliable for 1-6 knots) ?

[Nealius]

Active at Vaziani was 31, winds 2kts roughly straight down the runway. Active at Senaki was 27, but 09 ILS was working and since some genius only put one ILS at Senaki, I had to land with a tailwind.

 

I've attached the mission file.

2kts isn't enough to keep ATC's active runway and ILS directions in sync (2.5.x bug).

 

In your mission ATC's active runway is 31 but the ILS direction is set for 13.

 

You can either ignore ATC's directions and land on 13 using ILS or increase wind speed to 6 kts toward 125°T so both ATC and ILS will use 31.

 

Tested in 2.5.6.47404 using an A-10C

Ah, is that the bug where wind has to be over a certain speed for 31 ILS to activate? I was trying to fly by published approach plates, but there is none for Vaziani 13....
