PRMG glideslope flight director not working

[sLYFa]

As the title says, when switching on the flight director during PRMG approach, only the vertical needle works, the horizontal needle remains centered. It works in penetration mode though.

Bump, I've also noticed this. @Hiromachi could you have a look at this? It makes for some really interesting ILS landings to say the least...

Will add this to my testing list.

One and a half years later, issue still present. Couldnt attach track file as unfortunately none of them register switching on the SAU director.

PRMG doesn't usually track unless you come in an almost perfect (at least "perfect" for a high performance hand controlled cold war fighter) approach. The "slightest" (not true, you've to be off by a bunch of degrees, just tough for a MiG-21 to control in that finesse) slip to have from the perfect centre, or in height, and it isn't tracking at all. But, that depends on the map, on the airport, on the approach, on the approximation one managed to fly, etc.

Now, what airport, what map, what approach (some runways works in one side, not in the other), it isn't working? Without further details there's no way to check if it's "broken" (it wasn't not long ago, just hard to track sometimes), or maybe it's a different thing.

The pitch command used to work for PRMG guidance before, but it doesn't now. The PRMG signal zone has been a tiny fraction of its real life size since release and it's too steep.

For me it always shows pitch up command regardless of where I am on the glideslope.

Same thing with SAU in Auto mode. SAU holds glide path nicely regardless of flight director indications though, that is until 200m altitude, there it starts descending well below the glidepath.

We'll check this again, and fix if needed
