DaveRindner Posted January 31, 2015 Share Posted January 31, 2015 (edited) Well according to Wings of Red Star and Wiki MIG-21 has ceiling of 60,000 feet (18,000 meters). In DCS with empty -21 and 1/3 fuel, I cannot get above 13,000 meters (42,500 feet). Above this alt. my IAS is barely 320 kph. Even with flaps and/or AB I can't get to go faster or higher. Pull in flaps, and it drops. Obviously I know of no way to have a completely clean -21, i.e. without pylons. The effective usable ceiling with two R-60 and 400 liter center-line, is around 12,500 meters (around 41,000 feet).

portman Posted January 31, 2015 Share Posted January 31, 2015 Yeah you gotta stop climbing at at 10.000m, gain some speed, and then continue climbing. As far as I know, this is what the real pilots do. Mancher zum Meister sich erklärt, dem nie das Handwerk ward gelehrt! Link to comment Share on other sites More sharing options...
TurboHog Posted January 31, 2015 Share Posted January 31, 2015 (edited) I usually enter a climb at ~950 km/h, then climb with around 15 m/s to 6000-7000 m (IAS is around 750 km/h by then). Then I engage the afterburner and accelerate to supersonic speed (while climbing). I usually level off at 15000 m with a speed close to mach 2. With that speed I could easily reach 18000 m while cruising >mach 2. Zoom climbing from this altitude took me up to 34000 m once, but there is no way you can fly there. 15000 seems to be a good supersonic cruise altitude for me. Maintaining a high speed (and thereby a relatively low vertical speed) allows you to easily overcome the drag by a large AOA. Make sure your speed does not fall below 700 km/h or it will take a long time before you reach supersonic speed, especially while climbing a bit. Another method is zoom climbing, as portman explains in the post above. I prefer my own continuous climb method. I have used this method with a2a loadouts only...

Fishbreath Posted January 31, 2015 Share Posted January 31, 2015 I have used this method with a2a loadouts only... I think that's reasonable. The only A-G loadout I could see the MiG carrying at 10,000-plus meters is a nuc, and I don't get the sense that mission planners would budget return fuel for a high-altitude MiG-21 nuclear bombing run. :P Black Shark, Harrier, and Hornet pilot Many Words - Serial Fiction | Ka-50 Employment Guide | Ka-50 Avionics Cheat Sheet | Multiplayer Shooting Range Mission Link to comment Share on other sites More sharing options...
effte Posted January 31, 2015 Share Posted January 31, 2015 (edited) I posted the intercept profile by the book in another thread. Intercept profile by the book: Accelerate after start to reach 950 km/h TAS by 1000 m. Maintain TAS until 10,000 m. Accelerate to 1200 km/h IAS and maintain until M1.9, which is then used for the rest of the climb. The acceleration at 10,000 feels slow as molasses initially, but once past 1000 km/h the engine can breathe happily again and things start happening. Reheat from the get-go. Cheers, /Fred Edited January 31, 2015 by effte IAS after acceleration at 10k, not TAS. ----- Introduction to UTM/MGRS - Trying to get your head around what trim is, how it works and how to use it? - DCS helos vs the real world.
