cannot produce and mssing track file Getting ILS to Work

[Sabreliner]

 

 Not sure if this is a bug or not, but has anyone been successful in getting ILS to work?  I have the PRMG channels set in the DTC options.  When I select A/D and RSBN with the switch in AUTO, I get a course indication but no localizer or glideslope.  I have tried also in MANUAL mode to no avail.  Do I need to add an RSBN car to the runway to get ILS indication like with RSBN?

Try landing in Krymsk aerodrome and see if it works.  

[Sabadin]

I feel like Krymsk confuses the system because both runway ends use the same PRMG channel. Return mode works as expected until the handoff to Landing mode. Happens regularly to me when testing RWY 22. Meanwhile on the same flight I can quickly hop East to Krasnodar-Center and have it all work perfectly on RWY 09.

  Lately, I have been flying in the Marianas exclusively, and I have had no luck with PRMG there.  Will try Caucasus.

Maybe it's not obvious to you, but MiG-29 is not compatible with ILS. If you want to use PRMG/RSBN you have to put and configure the units at the airport you want to land at. Only some Caucasus (russian side) and Cold War Germany (GDR) airports have set PRMG/RSBN by default.

Works for me.

Never tried with RSBN/PRGM cars, but tried with Russian airports with embeded PRGM. 

When you use auto mode, you should use RETURN button as well. With selected beacon programed into DTC for that airport and airport number is selected. Also 0-179° - 179-359° switch needs to be set in position depending on runway heading. 

If you want to set MANUAL mode, you need to flip magnetic heading switch to manual and select runway magnetic heading. In lower part of navigation panel select adequate chanels. For example: 40 (on left wheel control knob for RSBN). And 38 on right wheel control knob for PRMG. RSBN & PRMG numbers are different and according to programmed beacons of that airport. Make sure RSBN switch is selected instead of ARK (ADF). At <20km flip the landing switch up on navigation panel.

EDIT: Correction to my previous statement regarding manual mode.

Hi guys,

RSBN and PRMG works fine. On my upcoming mini campaign (Desert Bad Guys - Fulcrum vs), I installed RSBN/PRMG on all campaign airfields. All of them on DTC as well.

it is already uploaded and just waiting release by the moderators.

Remember to put and activate 3 Cars:

- RSBN

- PRMG Loc

- PRMG Glidepath.

Use a channel number to RSBN and for PRGM add 2 to the channel number.

Good luck

The west directions are only active if there is enough wind from west (6-8 knots minimum). Else the east direction PRMG are active.

The only thing that puzzles me about Manual/Auto mode is that even if the RSBN channel is set correctly, after catching a path, the direction indicator needle (yellow) starts spinning. It simply lost the signal (Landing switch up). It's possible that the navigation system is actually only able to receive a single beacon signal, and if we're using PRMG, the RSBN doesn't work. The approach path can be manually set on the HSI and that's always a good indicator.

I noticed that also, but localizer and course is still present. PRMG works independently of RSBN and should not be issue when in final on runway. Once PRMG is established , RSBN is not needed.

Most likely you are right about inability to hold both signals.

In MiG-21Bis, signal can also be lost if you are flying low or obstructed. But not as frequent as in MiG-29A. But in my case both happened rarely.

The problem is that it's not being disrupted by some obstacle. In my opinion, it should still work, and contrary to appearances, the direction to the beacon is still just as important, even though we have a signal from the PRMG. Maybe it's a bug?

Maybe it is a bug, I am not sure.

I also have the yellow indicator needle spinning but only on the Syria map. 

Stetting up RSBN/PGRM cars on Kola,and Caucasus, the needle holds steady after switching to landing mode. No matter what airbase I set up the RSBN/PGRM cars on the Syria map, the needle spins once landing mode kicks in.

The thing is, that when you set the LAND switch up, the yellow needle isn´t showing RSBN, but the selected ADF channel. And if you have not programmed ADF channels for that airport and there is no other NDB in Range, the needle spins. I guess in LAND mode it is more important to show you where the outer/inner beacons are, than some RSBN, so you get guided into the ILS path better.   If it is the realistic behaviour of the MIG29, I dont know. But in DCS it shows ADF.

Good to know, I will check the it, thx! Btw. Are you talking about the frequency programmed under the Beacon buttons or in the ARK receiver and channel 1, for example?

Ah thank you so much! 

I've just tested this and I think I understand how its meant to work now.

In return mode, the blunt end of the yellow needle is pointing you at the RSBN at the airfield while the larger white needle and the circle in the HUD tries to to get you in position and on the course to intercept the localizer and glide path.

Once the NAV computer finds the localizer, it switches to landing mode and the yellow needle begins to search for the outer marker beacon also with the blunt end according to what channel you have your ADF radio set too.

Once passing the outer marker beacon it will automatic switch to the inner unless you have selected it first and do a 180 once you have passed the beacon.

You need to be landing using the runway the tower assigns you to use, or the beacons at the opposite end of the runway will be turned on and the needle will be homed in on one of them. This is also important to remember when setting up the landing direction when using the placeable RSBN/ PRMG cars and selecting the runway in the DTC!

So you are meant to have both the inner and outer marker beacons set up in one of the channels on the ADF radio for the airfield you want to land at but landing using RSBN/PRMG, its not necessary. The system is set up to switch to ADF anyway for airfields without landing aids and only marker beacons and can be back up for PRMG failure I suppose.

If you happen to have the ADF radio set up for another NDB or maker beacon at a nearby field in range, it will point to that.

So if it cant find the signal of the channel and corresponding frequency you have the ADF set to, the needle will just spin endlessly searching.

I am talking about the ARK receiver frequencies you set up in mission editor in the aircrafts config tabs.
