RSBN is "a sort of" VOR but not exactly a VOR The off flag works in landing and glide path mode. "Flags" are related to the SDU subsystem: from the Aero L-39 manual: pg 1-62 and pg 1-78 The pilot switches on the SDU system manually after penetrating area of stable receiving the localizer signal, which is indicated by disappearing of the "K" warning flag. SDU activation is indicated by hidden "K" and "T" (well, it´s not an F, but I can´t write in cirilyc...) warning flags on the RMI.

The "ARK" or "ARC" is the russian name for the western ADF nav system. It uses the same NDBs. The beacons with the morse codes and frequencies are defined in the beacons.lua file of DCSW maps (caucasus for example) alongside with VOR, TACAN, ILS, RSBN, PAR... and other navigation aids. At the moment we´ve got: .- MiG-15: ARK-5, manual tuning like the ADF of the Sabre and Huey. .- Mi-8 and L-39 Albatross: ARK-9, manual tuning system with the "inner" and "outer" selector. You can tune two beacons and select the one you need. .- KA-50: ARK-22: presets only, you can change the presets editing the associated lua file. All these modules use the beacons and beaconsite LUAs of the map. If a NDB is destroyed or a ILS in destroyed you lose the signal and the nav aid. Leatherneck MiG-21: it uses a file that can stows until 90 RSBNPRMG stations and 72 points for "ARC" in a xyz file with an associated morse code wherever you want in the map. You can even put a beacon in the middle of the Black Sea. It is not a real ARK/ADF. It´s a simplified nav system. Sorry for my english. Send me a PM if you wish. Regards.

It´s its normal behaviour. You are in "navigation mode" so the PRMG part of the system is turned off. When you are in "Glide Path mode" you´ve got one flag off in the HSI and in the ADI (if the SDU is activated) When you are in landing mode, the PRMG part of the RSBN-5S/RSBN-4N is activated and the flags are off (in the HSI and in the ADI if the SDU is on) if you are in position to intercept the signals of the system. Pg-131 of the manual: "RSBN-5S: navigation system".

Thanks for the files! Only a consideration, AnnaNass, the ARC column in your files is only for the 21 that uses a simplified navigation system. All ARK systems correctly modeled (ARK-5 for the MiG-15, ARK-9 for the Hip and Albatross and 22 for the KA-50) use the NDB column. If you can, rename the ARC column to something like "ARC-MiG21" to avoid confusion.

RSBN: for navigation only. Sort of VORTAC. 4 in the Caucasus area: Krymsk, Krasnodar, Maykop and Mozdok. PRMG: for landings. Sort of Russian military only ILS. Available at the 4 military bases of the Caucusus map: Krymsk and Mozdok, available for both approaches, obviously only available in the active runway. Maykop and Krasnodar Center, only available for RWY 22 and 09 If you set a RSBN channel in the PRMG component of the RSBN-4 system you get a bearing indication of the position of the RSBN beacon only, with the azimuth light of the system on, never with the distance light on, independently of the runway that is active. I don't see any problems using the system. One more thing, do not compare this system with the more simplified system that is used in the 21. It's the same RSBN-4 only in name. The L-39 depicts a real RSBN/PRMG system that is more useful to navigate across the map Sorry for my English.

Yes. You need to set the RSBN and the PRMG channels to get all the signals. They are different but complementary signals with independent beacons. Approach to the AFB via RSBN, then set descend mode to intercept glidepath and then set landing (PRMG signal) to land.

Well, after some readings, it´s not a bug. In short. If you set a RSBN frequency in the PRMG selector, you´ve got azimut indication "to the RSBN position" not to the PRMG glidepath. RSBN and PRMG are different beacons. You can have a RSBN without a PRMG associated. In the USSR, RSBN were used for civil and military air navigation (sort of VOR/DME) but PRMGs are military systems, so there are only PRMGs at military airfields. In the Krasnodar or Maykop examples, if the RWY that have PRMG is closed, the PRMG signal is turned off. If you set the RSBN frequency in the PRMG and set landing mode you have got indication of the azimut position of the RSBN beacon, but nothing else. Sorry for my english.

Sorry. I have the same behaviour in Maykop AFB, so no wrong "," placement in the lua. Maybe something related with the operation of the RSBN coupled with PRMG systems? Anyone able to look at the russian section of the forum? Thanks!

Yes, winds must be over 3m/s (10 km/h) to activate RWY09. A bit strange that ATC prefers RWY27 when the PRMG is active only in RWY09. Edit: I´ve tried Maykop and I don´t have this behaviour. Looking at the Beacons.lua file it could be an error in the Krasnodar - Center definition, a wrong "," placed maybe.

I can land with PRMG aid in RWY 09 if it's the active RWY. I try it later. Have you tried Mozdok AFB, the other with only one assisted RWY? Edit: OK. I see it. In PRMG 40 you have got azimuth correction only. The system on board (RSBN-4) is receiving signal. I´ll try to find something about RSBN with coupled PRMG systems. Thanks!

As the manual says, and you can see in the ME, Krasnodar AFB and Mozdok AFB only have PRMG system for a guided approach in only one RWY (09).

Yes. And it is the only helo without this option in the ME and in the mission planner. I use a little mod that I have made to sort this.

A Cibit says, you need to use the mssion planner to setup the frequencies or open the missions in the ME, assign the frequencies that you need//want and resave.

Thanks to all! For sure, when we 've got the training missions and the final manual, all will be explained better. Regards.

For the ARK-10 system it should works like something like this: Inner: pushbottons and Outer: "wheel" (sector) selector. Like the L-39 system. The only difference is that the L-39 ARK-9 is a manual one and the ARK-10 only works with presets. The inner and outer is not part of the "MARKER" system. It allows you to select between ADF frequencies, outer: frequencies set by the "Wheel Selector": (SECTORS in this sim) and inner for the frequencies set by the pushbuttons (1-9) But for the LNS-21, yes, it works to switch between markers. Maybe in 2016 we can see a real nav system for the 21, like the L-39.

It isn´t modelled. It works with the "Inner -Outer" selector of its left (without use in this sim). Part of the ARK-10 navigation system, that we haven´t properly modelled. Regards and sorry for my english.

Hi Nikola, Sorry for the delay. These are the steps for a simple navigation using the RSBN in manual, RSBN in manual +ARK and finally RSBN in auto mode. Navigation with the 39 using different systems. From Anapa to the Bay of Gelendzhik, to Smolenskaya and landing at Krymsk. 1st leg: Anapa to Gelendzhik Bay: RSBN in manual mode, no land signal from a station. With the plane started, we set the RSBN distance via the distance selector: 72km and set the azimuth via the azimuth selector: 132º We´ve got indications of heading (HSI) and distance (the drum counter bellow the HSI) If we follow the indications, we reach the Gelendzhik bay. 2nd leg: Gelendzhik – Smolenskaya. Using RKL-41 and RSBN in manual mode. We tune the ADF of Smolenskaya (662) and set the distance from Gelendzhik bay (68km) and estimated heading (63º) We can navigate with the RKL-41 and with HSI indications and distance indication. 3rd leg: Smolenskaya – Krymsk. RSBN in automatic mode with a land signal. We tune Krymsk RSBN (28) and PRMG (26), distance is computed automatically. We also tune Outer (408) and Inner beacons (803) for a more precise approach. ADF in auto mode. Remenber that the Auto mode only change between Outer and inner Beacons automatically IF you are in path AND landing gear is down. If these parameters are not meeting the ADF will point to the outer station for a new approach. Contact Krymsk for the active Runway. Landing with SDU mode connected for a moving marks in the ADI. Sorry for my english. Tarres

It's a bad traslation. It's a generator not an APU. Regards.

I had posted this in the general forum but maybe it's better here. Ability to setup the presets of the UHF Radio in the ME like in the Mi-8 (R-836&R-828) And in the KA-50, it would be great to have the ability to setup in the ME the ARK-22. It would be great thinking in future maps and their associated NDB, if available.

I have a modded dbcountries.lua with 21 available to Egypt, Serbia, Germany, Finland and Bulgaria with their respective liveries. But it's incompatible with the multiplayer. LNS has to add something to their definition Luas or send to ED a request for add these lines in the code (like VEAO or Avioddev have done) along with the line that allows to have the QNH in metric. Regards.

Ok. thanks Derelor. Any info for the correct use of these "frequency ranges"?

In DCS Beta 1.5 update2 the ARC-5 tab for setting the presets is not present in the ME.

I´m not at home until tuesday. Information are available in: Aero manual of the L-39C. ED L-39C manual MiG-21bis Operation manual. I´ll try to make a better post next week. Sorry for my english and this "telgegram" (mobile devices)
