Now, for these rearview mirrors, I always wanted to know if they were used and who did it, this pic belongs to an SPS as the pic says, but, more light can be shed, if possible Quote

The canopy is tilted to the right. The MiG-21PFM was the first version of the fighter to feature two rear-view mirrors in the cockpit. Later they were also used on vehicles of the MiG-21SM family. Only on the MiG-21 MF they were replaced with a TS-27LMSh rear view mirror. The MiG-21PFM was also equipped for the first time with the improved RP-21MA Sapphire radar. Two rear mirrors on the MiG-21PFM canopy. These mirrors were not present on early MiGs. This aircraft is also equipped with a TS-27AMSH rear-view mirror. In addition, this is an early version of the MiG-21PMF, since the aircraft is equipped with a KM-1 ejection seat. https://military.wikireading.ru/33447?ysclid=lzs4o0c1wx378987657 TS-27AMSh is the rearview periscope common for other aircraft too (MiG-23, Su-25, etc) View from Il-76 2 Quote

+FLOGGER23 Posted September 2, 2024 Posted September 2, 2024 Hello guys. While making the cockpit I found this counter, which is present in some PFMs, at the beginning I thought it was the ammunition counter, however, I have my doubts now, can someone tell me what is it for? Quote
Svetlin Posted September 2, 2024 Posted September 2, 2024 (edited) I am sorry, I do not know what exactly this one does, but it is some sort of a distance counter. The Cyrillic text says "Distance in km" at the top, then "Increase" at the right side and at the bottom the text says "Set starting with the hundreds in the range between 0 and 9". I hope that at least the translation could be helpful. Edited September 2, 2024 by Svetlin Removed incorrect specualtions. Quote
+Gepard Posted September 2, 2024 Posted September 2, 2024 As Svetlin said: расстояние в км ... Distance in km увеличение ... increase установ нач с сотен не переходя 0 и 9 ... set start from hundreds without going to 0 and 9 If you can post a photo of this instrument, where it is located on the board. I would ask in a german forum where old MiG pilots and technicians are to find. They are always helpfull. 1 Quote

+Gepard Posted September 2, 2024 Posted September 2, 2024 I just posted your picture in the german forum. Let's see, when we get an answer. Maybe tomorrow, it's already late in Germany. 1 Quote
Svetlin Posted September 2, 2024 Posted September 2, 2024 (edited) The MiG-21bis flight manual for DCS identifies that instrument as an indicator for the distance to the ground Radio System for Close-distance Navigation (Индикатор дальности РСБН). Source: https://www.digitalcombatsimulator.com/upload/iblock/8a3/6o8xp14vqfyna8eos7jn6g5vynfopr3f/DCS MiG-21bis RU.pdf The manual contains some detailed information about the use of the indicator as part of the aircraft navigation system. The problem is that the text is in Russian and a bit too technically complicated for me. Apparently the flight manual of the aircraft specifies a recommended flight profile for approaching an airport. At a predefined distance from the ground Radio System for Close-distance Navigation, the aircraft must be at a predefined height. So, that instrument informs the pilot for the distance to the ground system and he controls the height and speed he is flying at, making sure he is approaching the airport in a proper and safe manner. Hope that helps. Edited September 3, 2024 by Svetlin Quote

+Gepard Posted September 3, 2024 Posted September 3, 2024 (edited) I got the answer: "Das war wimre der "Entfernungszähler". Musste von Hand auf einen Anfangswert eingestellt werden und zeigte die Entfernung zu dem am ARK-10 eingestelltem Funkfeuer an. Die Berechnung funktionierte analog über Kurswinkel vom ARK und Geschwindigkeit Vw vom Staurohr, ein ziemliches "Schätzeisen" und deshalb meistens nicht genutzt. " translation: "That was AFAIK the "distance counter". It had to be set to an initial value by hand and showed the distance to the radio beacon set on the ARK-10. The calculation worked in the same way using the course angle of the ARK-10 and the speed Vw of the pitot tube, a bit of a "guess" and therefore mostly not used."

+FLOGGER23 Posted September 9, 2024 Posted September 9, 2024 Guys, would it be too much to ask for a flight manual? (I have the one for the FL, US and UM already) That would be to pinpoint some of the switch/know functions, yes, because I have a big OCD to have all named correctly! Or, I will post specific questions for some Items... Whatever works for all of us... Quote

+daddyairplanes Posted September 10, 2024 Posted September 10, 2024 not the right answer but the first thing that popped into my mind seeing the red version https://www.youtube.com/watch?v=LwjP8HCpE4E 1 Quote
+Gepard Posted September 10, 2024 Posted September 10, 2024 IIRC the red button had something to do with the brakes. But it would be helpfull to have a better picture. 1 Quote
Svetlin Posted September 10, 2024 Posted September 10, 2024 (edited) First picture: The red button on the left says EMERGENCY BRАKE (АВАР. ТОРМОЖ.). The upper red handle on the right is a selector switch - selects between the main and the emergency (or back-up) air-pressure sensor (in russian air-pressure sonsor is abbreviated ПВД). So, the text there is ПВД and also АВАР. and РАБОЧ. (АВАР. stands for emergency and РАБОЧ. stands for working, i.e. main sensor). The lower red thing is a cover over the button, which engages the emergency release of the landing gear. The text there is АВАР. ШАССИ (which stands for emergency and landing gear) Second picture: The red button on the left says EMERGENCY BRАKE (АВАР. ТОРМОЖ.). The other one says DE-ICING PRESS (ПРОТИВООБЛЕД. НАЖАТЬ). So, the first one engages the emergency brake and by pressing the other one the de-icing system for the windscreen is engaged. Edited September 11, 2024 by Svetlin Information added 2 Quote
+FLOGGER23 Posted September 11, 2024 Posted September 11, 2024 Guys, I found this and it's pure gold! it answers almost all my possible further questions (I know I will have more) MiG-21 walkaround and cockpit tour 5 Quote
+FLOGGER23 Posted October 2, 2024 Posted October 2, 2024 Hello guys, good day all, I have another doubt/question: Radar On the MiG-21PF/PFM/R Series they used the RP-21 Radar and I have seen in game you can basically turn it on, see targets and THAT IS IT, however, I have seen you can track and boresight targets as shown here: This I assume can be done (fingers crossed) however, something I would ask for clarity game engine-wise, I have seen the RP-22 can discern the clouds, can this be achieved for us? Also, does this radar have any (limited) air to ground function? TIA 1 Quote
+Gepard Posted October 2, 2024 Posted October 2, 2024 You could switch the RP-22 to send out a continuous beam, so that you could use it as rangefinder to a ground target. But ground mapping was not possible. The RP-22 had more in common with RP-23 of MiG-23, than with RP-21. It was able to guide the R-3R missile, but not the RS-2US (AA-1 Alkali). 1 Quote

Some compromises had to be made, but overall function of RP-21 could be modeled just fine. You just need to create proper symbology Quote
