@Hangar200 it depends on the quality of the ILS that both the aircraft and the designated runway are equiped with. These qualities are standardized and divided into five different levels. ILS CAT I is the lowest level, and has a minimal decision altitude of 200 feet and a runway visual range of 1800 feet for a properly lit runway, or a minimal visual range of 2600 feet if that is not the case. ILS CAT IIIC, the highest level, has no minima.
@Maico looks like we’re getting somewhere! I think you’re a little to high now before, I thought you were trying to activate the ILS 1000 metres in front of the runway, but what you were actually doing is flying 1000 metres high, which is fine! You won’t get a glideslope signal that far out, it has a maximum range of about 25km. I crunched a little more maths for you, hope it helps, all altitudes are QFE relative to the airfield you are trying to land at. So if you want to use baro, consider practicing on a runway close to sealevel like Krymsk or Sochi.
At 25km, the glideslope altitude should be around 1800 metres.
at 20km, the glideslope altitude should be around 1400 metres.
at 15km, the glideslope altitude should be around 1050 metres.
at 10km, the glideslope altitude should be around 700 metres.
at 5km, the glideslope altitude should be around 350 metres.
at 1km, the glideslope altitude should be around 70 metres.
Since you have trouble acquiring the glideslope, and I know that the glideslope emits in a 2-6 degree angle, I also calculated the min and max QFE altitudes you should be getting an (extreme high or low) glideslope signal.
at 10km, the min and max altitudes for a GS signal are in between 350-1050 metres.
at 1km, the min and max altitudes for a GS signal are in between 35-105 metres.
If there are obstructions, it might not always be possible to get a signal at the minimum described altitude. I think Nalchick and Sukhumi or Gudauta have buildings close to the runway.
If the SAU (autopilot) is trying to get you killed, be sure to give it plenty of speed and atleast take-off flaps! Remember that the SAU cannot control your throttle, so keep the speed close to/over 400km/h. The fishbed doesn’t really mind landing at higher speeds with a lower rate of descent.
The PRMG doesn’t really care about the position of the RSBN/ARC needle. You can put it on 70 (or whatever the magnetic bearing of your runway may be) for your own reference (it’s nice for getting close the localizer signal) but it is not required.
Hope it helps! Hopefully you can do a full PRMG approach soon for me it works. It gets me to within 1000 metres of the runway so I can complete the landing. (it will fly me all the way to touchdown… but it will impact the runway with a 10m/s* descent rate which will send you bouncing and cartwheeling).
