Mbot: good info and pics!

Toss bombing works pretty good. Just change the inicial climbing point from 7 km to 9km of the target zone.Toss Bombing it safer an usually more practical than the above "over the shoulder" release. You will be almost 10 km from the target área at its air defenses (if they are over the target), this will give you preciuos time before releasing the Bomb. You only need about 10 second to climb from ground level cover to 1500 m and release the nuke. Even if you dont have ground cover for part of the climbing Sams will take longer to lockon and reach you. Some nice info from Mig-21 by Alexandre Mladenov: NUCLEAR FIGHTERBOMBERS There were several MiG-21 variants that featured dedicated subvariants with added-on nuclear capability, distinguished by the letter N (derived from the word Nositel – carrier [of a nuclear bomb]) in their type designation. The MiG-21S’ nuclear-capable derivative bore the Type 95N designation; MiG-21SM – Type 95MT (or Type 15N); MiG- 21SMT – Type 50N; MiG-21M – Type 96N; MiG-21MF – Type 96FN; and the MiG-21bis – Type 75N. The nuclear-capable Fishbeds introduced dedicated wiring to enable use of a single nuclear bomb carried on the centreline pylon, together with a control panel in the cockpit, installed on the top of the fixed windscreen frame. The control panel enabled the pilot to arm the bomb, perform its emergency jettisoning and set the desired type of detonation – airburst or upon impact with the ground. The Soviet Air Force’s threesquadron fighter-bomber regiments, stationed in the 1970s and 1980s in East Germany and some other East European counties, had one of their component squadrons permanently equipped for the tactical nuclear role, with the nuclear bomb’s control panel always installed. Ground crews regularly practised fitting training rounds, while pilots practised delivery profiles using standard practice bombs. The nuclear bomb was designed for delivery in either level flight or by the so-called toss-bombing method. The latter called first for acceleration in ultra-level flight at low level to 1,050km/h, then a 45º climb and release of the bomb at about 1,500m (4,920ft), which then impacted the ground some 7km from the release point or detonated in the air at low level in order to deliver a better blast wave destructive effect on surface targets. There was another, more precise derivative of the toss-bombing method – the so-called over-the-shoulder release – which called for acceleration in level flight to 1,050km/h at 100m (330ft) above the terrain and then commencement of a looping manoeuvre. Bomb release took place when the nose went just beyond the vertical, at a 106º pitch angle, and at an altitude of about 3,000m (9,840ft). In this event, after release the bomb travelled on a ballistic trajectory, initially going sharply upwards and then reversing downwards, hitting the ground immediately beneath the release point. After release, the MiG- 21 pilot had 1–2 minutes to escape from the blast wave at full afterburner before the bomb’s detonation, at a distance of some 10km. The RN-28 bomb was the main nuclear weapon carried by Soviet tactical aircraft in the 1970s and 1980s, superseding an earlier design known as the RN-25. A low-yield weapon, the RN-28 was equipped with a programmable control unit that allowed the type of desired detonation – airburst or upon impact with the ground – to be set before take-off, while the bomb’s yield was adjustable between 1 and 10 kilotons.

I recommend you read / check the manual for fuel light indicators sequence. If I remember correctly the 21 has 2950L in internal tanks and it can carry 800L or 490L external ventral (central) tank and/or 900L in 2x450l wing tanks. The mig has 2 remaining fuel indicators: 1) the round one (yellow) witch uses a manually entered total fuel value as initial reference (done by ground crew) and then takes in account used fuel to calculate remaining fuel. It can have errors, for example if you release and external tank before time it will indicate more fuel than you really have. Fuel is indicated in Liters x 1000. 2) The light system, linked with real remaining fuel in internal tanks. I usually carry: Internal tank: 2950L or Internal 2950L + Ventral 800L tank:3750L Total.Tank is released when ventral tank empty light goes on continuously. You will read about 2950L remaining in yellow fuel instrument if it's working ok. or Internal 2950L + ventral 800L ext. tank + 2 450L ext. tanks. Total fuel 4650L. Wing tanks will empty first. No light will go on. I release the wing tanks when I have less than 3750L (3650L to be safe). The logic for the wing tanks light might be wrong. Ventral tank light works perfect AFIK.

Same here if I try to update or repair DCS Open Beta.

The thread is tagged as [Resolved] but in 1.2.15 build: In game AoA is positive, not "almost" horizontal, at 500 km/h IAS and it descends with speed to the point of reaching negevative values at max speed (around -2,5 Alfa degrees at level flight). As linked in a previous post, from Mig-21 Bis real manual: "In level flight, at speeds of 500 km/h and higher, the angle of attack indicator pointer is in an almost horizontal position. ...will remain practically constant while...passing the transonic speed range, irrespective of the altitude or external loads " AoA indicatior is not only important to control high G maneuvers, it is used "to promote the aircraft handling accuracy", is the reference instrument for approaching and landing. Maybe the AoA of the EFM is to hard to fix without braking other EFM parameters or the manual is inaccurate or I just misinterpreted it (not being sarcastic here, the manual has a bad translation to english and it's hard to read/interpret sometimes).

Just a minor bug. The keys commands for switching the nose cone from auto to manual and manual to auto seem to be inverted. Cone Auto keys (RCtrl + RShift + /) place the switch in Manual mode and Cone Manual keys (RShift + /) place the switch in Auto mode. This is in DCS 1.2.15.

Try no to respond GGTharos provocations (it does really look like he got some hits from 21's). Lets stay on topic and keep this nice thread going. There is a FC section in the forum where FC "realism" can be discussed. And theres a MIG-21 bugs section where bugs or errors about missiles can be reported. (By the way you cant even calibrate the ADI in a FC level aircraft)

Its kind of funny to read post from people who "fly" FC level planes talking about realism. There is no point in comparing FC with DCS modules, they are clearly build with a different standard and aimed at a different public. Someone who gets on a DCS - MIG 21 in the 104th server has balls and is probably inclined to strategy, patiency, realistic flying and navigation and will most likely show a mature and respectful behavior. Within FC level players you will probably find the opposite characteristics..

What happened, you got shot by a Mig-21? :smilewink:

2 - Black Sea Sovereignty II. (Anti-Ship) 02/27/1978. Black Sea MIG-21 Squadron. USSR. Situation: Two NATO warships (a cruiser and a frigate) and two supply ships were detected this morning by a MIG-25 recon flight. They entered the Black Sea from Istambul Strait and are heading north. We will massively and exemplary attack this warships with two waves of TU-22s and 30 KH-22N antiship missiles. The missiles will be launched in altitude mode, climbing to 27 km before falling to the targets at mach 4.6 with their 1000 kg load. We expect 2 to 3 missiles to hit each target. No antiship missiles will be wasted in the support ships which are the secondary objective of the mission and your primary objectives. Both TU-22 waves are already in the way to the objetives, we expect missile launching in 10´, impacts in 15´ and satellite confirmation in 2 hours. Objective: Find and destroy the supply ships between WPs 1 and 2. We are based at ANAPA. Your MIG-21s are loaded with a pair of S-24 rockets, 3 external fuel tanks and JATO take off system for your overweight. You will fly 180 km to de 235 ° of ANAPA RSBN 1 (WP1) at low altitude (under 100 m), subsonic speed and search and attack the cargo ships between WP 1 and WP 2. Your allowed to briefly climb every few minutes to get RSBN signal to aid in your navigation if necessary. Note: Your two objectives navigate a few km behind (south) of the warships and are covered by their air defenses. You can only enter combat zone when and if the Frigate and the Cruiser are eliminated by the KH-22 missiles between 9:50 and 9:55 am. With current climate we won’t have confirmation of the elimination of the warships until the radar satellite is in position, 2 hours from now. But you will use your RWR to find out. If you don’t detect radar signals from enemy ships you will proceed with your mission. If you detect radar signals before 9:55 am, keep safe distance from it and low altitude, continue mission when and if they disappear. If you detect radar signald after 9:55 abort mission and RTB, at least one warship is still operative. Good luck. Climate: Covered, light rain, clouds at 3000m, light wind from SW, visibility: 10 km. Loadout: Pilons 1 + 2 : S-24 Rockets. 2 wings 490l fuel and one ventral 800L tank. Threats: Warships air defenses. Possible F-4 CAP. Bingo Fuel: 1200L. Friendly AWACS: 124.00 AM, Chanel 0.

Lots of nice improvement in 1.2.15. But drag should increase square with speed and with it longitudinal desaceleration. You can check accelerations charts, the slope at 1G is for level flight. I certainly can't keep a steady speed between mach 1 and mach 2, in level flight. Your are either accelerating with AFT on (even at lowest level, 655 C exhaust temp.) or descelerating with afterburner off. I only tested at 10000 m altitude. I can't imagine a real Mig-21 pilot constantly turning on and off the AFT to keep a mach 2 speed, and its not in the real manual either. The 3 or 4 minutes limitation is only for emergency AFT. Hight altitud supersonic flights requieres afterburner, it is written in the manual. Max speed at high altitud and level flight should be reached and maintained with afterburner. All the procedure is very clear in the real mig-21 bis manual. With the current 1.2.15 there is no drag limitation and max speed is reached when engine fails, not when Engine Power = Drag.

This might be a problem now. Drag doesn't seems to increase with speed at all near max speed. Mig over speeds too easily and we have to continuously turn afterburner on and off to try to mantain max speed without engine failure. Check post #8 here: http://forums.eagle.ru/showthread.php?t=136200

Does the mig still fly level with negative angle of attack? http://forums.eagle.ru/showthread.php?t=135653 Maybe LD tried to fix it and this is an unexpected consequence, just guesing. Edit: checked and no, the MIG is still flying with negative AOA.

Thanks for sharing Winter. Most of us have been or will be in each of dose epic situations. Good read.

After a fast testing last night I have the impression (have to test it more and compare to real charts to be sure) that now, with the ¨scripted¨ speed limit gone, the mig accelerates to much beyond max speed, always to the point the engine quits. I´m concerned because this beta feature might hit the official version tomorrow. As it is right now its very easy to overspeed. And you know its very difficult to maintain a steady speed between match 0.9 and 2.05. All speeds between mach 1.0 and over mach 2.0 requires afterburner and afterburner is practically or ON or in OFF position. There is very little range between min and max afterburner to choose a steady mach speed in level flight. If your climbing with AFT you can easily choose your speed by changing climbing vertical speed. But when your flying level between mach 1 and mach 2 your are either slowly accelerating to max speed with AFT on or descelerating with AFT off. You will only get a steady speed when you approach max speed. This dosent happens with the corrent physics, the mig continues to accelerate until engine failure. Does it makes sense? How are we suppose to maintain a supersonic flight at a steady (max) speed? Continuously turning ON and OFF the Afterburner? Again I have to do more testing, I´m at the office right now with clients waiting. Maybe Im wrong and its easy to use "little" afterburner and prevent over speeding. I will get horizontal G numbers and compare them with the chats this weekend. From 1.2.15 change log: Engine over-speed limit removed in simulation mode, engine damage simulated. Fuselage over-speed drag limit removed in simulation mode

The problem with speed limit (longitudinal acceleration to max speed) seems solved since the last beta update 1.2.15. Good job LN. Now It seems the mig overspeeds too easy, need mor testing. We have to learn how to control max speed and prevent engine shut off or damage.

But you can get good kills without using the radar for searching. Check this. Of course is a very lucky day and after at least a pair of hours flying:

Thanks for sharing Hadwell. I will try using a little more the radar, sometimes it takes too long to find targets using only your eyes.

Thanks. Im not sure about SPO detection distance for F-15 radar, maybe between 50 to 100 km. I think F-15 can see our radar in its RWR at about 30 km, it should be much more but maybe I´m wrong, none of my squad mates usually fly FC3 level planes. F-15 radar can see you at 100 km. But I always try NOT TO USE THE RADAR for searching, it makes the ambush pointless, FC 3 fighters have a much better and over simplified RWR, search radar, target info, long range missiles, more engine power and extra fuel for combat manuvers. You will became the prey rather than the hunter. The exception for me for using the radar is when hunting for A-10s, and, maybe, when I´m behind enemy lines, haven't seen a target for a while and im flying from the enemy base to bulleye: I might turn it on for I few seconds, If your quick enough maybe the enemy wont see the "U" in its RWR and If it dose it might think your a friendly Mig-21 coming from his base and be too lazy to turn around and check. But usually is better to continue searching visually. That black smoke is easy to spot, especially if you have an AMD card.

This is wat I usually do in the 104th: First get to know the mission. Find the general flight path and combat area of enemy fighters and attack airplanes (airport to bulls eye for fighters and air port to TA for ground attack planes). Chose if your going hunting for A-10s and SU-25s or FC3 F-15s and Su-27s. For hunting ground attack planes: 1)Know their target areas. (taking picture with your phone from their briefing map works excellent). 2)Plan a flight plan to their TA going arround the bulls eye and avoiding enemy fighters. Calculate Bingo Fuel. Usually flanking the bulls eye at 80-150 km distance is enough, depends of the mission. You can fly to TA low and using terrain for masking, I usually climb to over 12000 and fly about 200 km to target area at 2100 km/h TAS. Its only 10' a flight. You will condensate (white smoke trail) and be seen from a great distance at an altitude from 8000 m to 12000 m. So or stay under 8000m or be very carefull when descending from 12000m, do it fast and parallel to enemy planes expected bearing. You can overfly at high altitude the enemy target areas and find which on is on fire and smoking. Then you go down and look for targets. Take care of SAMs and enemy fighters doing CAP. For hunting FC 3 level Fighters: 1) Find their general path and a nice corredor in the mountains to ambush them, between their base and the bulls eye. (It only works fine is you can hide with terrain masking). If you get closer to their base is usually safer for you as long as you stay away from their air defenses. 2)Make a flight plan to this corredor, flying safely around the bulls eye, low and with as much cover as you can get. 3) On the ambush zone, "behind enemy lines", fly low in the valles and hide from any signal you get in the "RWR". Keep looking at the horizon and up while zooming. You will eventually see a FC3 F-15, Su-27 or Mig-29 flying by. If he is not to far away or facing you, get at his six trying to save fuel, IFF him (if youre uncertain) and fire. Sometimes you are lucky and you get a pair of F-15s in formation. When they are flying high they are easily spotted if are popping black smoke (no AFT, sub mach speed), and easily reached with your Mig-21 with afterburner on. Buy you will burn precious fuel and might be exposed to other fighter sensor field of view. I found that good FC3 pilots usually fly in pairs, at high altitude but just under condensation zone and a few km away from the usual path to bulleye.

Thanks.

Thanks Gezahu. Notice that those are official manual numbers. I tested it in DCS and the mig will use and average of 200 l / 100 km ( from 1,8 to 2,2 L /km instead of the 1,65l/km from the manual), loaded whith 2 missiles, cruising @ 12000m and 520 km/h IAS, almost full mil power, no AFT. So you will get even at around 400 km (Sea level slow vs 12000 slow). At 12000m of altitude your 520 km/h IAS will be around 900+ km/h TAS. The thing is, being the Mig a Mach 2 fast mover, who wants to fly it so slowly for so long? I only fly so slowly when I RTB low on fuel. If I have extra fuel I always use all the after burner I can. In most of the missions, if TA is under a 150 km distance, I will go to TA at 80-95% power at low altitude (IAS 650 to 1050 depending how much fuel i want to use). If its over 200 Km and its safe I will climb an fly high and fast to TA. Then, if Im still alive, I would RTB low and choosing the speed that will make me arrive at the airport with 200 to 700 l of fuel left.
