Frederf Posted March 4, 2016 Posted March 4, 2016 The switch "MSL - NEUT. - RGM" or "СС - НЕЙТР - РНС" which is also called "C3. AA missile type select switch" in the DCS MiG-21bis manual is not working according to the real aircraft. The switch only determines the priority order of missile types to be released if mixed types are carried either in selective (1, 2, 3, 4) or salvo (1-2, 3-4) shootoffs. In cases where only one type of missile is carried then the switch position does not have any effect. The airplane will easily fire up to 4x R-3S or R-3R missiles despite the switch being in the any position the entire duration of the flight. If R-3S loaded station 1 and R-3R station 2, the switch is set CC, and armament "1" is selected, then the following happens. When a missile is fired it will be the R-3S first and the second missile fired will be the R-3R. For the same example but station 2 is selected instead then the firing sequence is the same as above because the type priority requires the infrared type to be fired first. If the same activity is done but the switch is in the RGM/PHC position then it will be the R-3R fired first and the R-3S second. If the switch is in the NEUT./НЕЙТР positioned then the order of firing is determined by the station number priority sequence which in this case is 1-2-3-4 for armament selector in position "1". ("2" is 2-1-3-4, "3" is 3-4-1-2, "4" is 4-1-2-3). The armament selector switch does not need to be changed in order to fire off all missiles under some circumstances. For example if one type of missile is carried then the selector in the "1" position will allow four missiles to be fired by four presses of the launch button with the selector being in the "1" position the entire time. If mixed missiles are carried then the above is also true but the missiles orders may be different (CC first, PHT first, or neutral with the order being unchanged from the station priority order). In the case of a misfire of a missile the selector must be manually changed to the next missile-in-turn to continue the firing sequence since the airplane will attempt to unsuccessfully to re-fire the failed missile until it is detected to depart. If 1-2 or 3-4 positions are set on the selector then the salvo is launched according to the missile type priority switch, CC first, PHT first, or neutral (by station order). I do not know if salvo is selected (e.g. "1-2") will a second press activate the other salvo (3 & 4 in this case) without the selector being changed or not.
Hook47 Posted March 4, 2016 Posted March 4, 2016 This is a fair point and something I had come across in study. Would be nice if LNS could implement this as it would actually be useful
Bestandskraft Posted March 4, 2016 Posted March 4, 2016 Frederf, you may wish to report your findings on the public bugtracker, more so since a report about some of the issues detailed in your post already exists (https://leatherneck-sim.mantishub.com/view.php?id=81).
Tarres Posted March 5, 2016 Posted March 5, 2016 Frederf, to complete your perfect explanation only one thing, according to the Technical manual of 1982, there is no possibility of "asymmetrical loadouts", both inner or both outer pylons must be loaded with the same type of missiles or rocket pods or bombs. Example: Pylons 1-2: 2xR3S or 2xR13M, or 2xR3R, or 2xFAB100. NO R-3R in pylon 1 AND R-3S in pylon 2 allowed for example. Table here: http://www.muzeumlotnictwa.pl/index.php/digitalizacja/katalog/2309 Pages 155-156, with the corresponding settings of the selector knob and IR-Neutral-SARH switch. This manual covers the weapons employed and all the parameters regarding the weapon system I think. Regards!.
