Okay, I think I've got it! I've been able to make several kills, some of them BVR, with the RVV-AE. Again, is there a way to tell how many chaff and flares I have left in the MiG-29S?

On the real aircraft there is a counter on the front panel(see attachement), but I don't know if this is currently working in the sim.

Range = distance listed in a book or on a wiki

is not a valid equation.

Range = mathematical expression incorporating: launch velocity, target velocity, difference in gravitational potential energy, atmospheric conditions etc.

Change any of the variables in the real equation for range and the resulting range changes.

Let's take an example:

Say you're flying at about 7500 m, and there's a target that's an F-15. You're at a nice 220 m/s, but what effect does the target's velocity have?

Say it's a foolish person that's been closing on you at max afterburner for quite a while trying to get above Mach 2, so they're adding about 500 m/s to the effective speed of your missile.

If your missile is in the air for 10 seconds, 500 m/s * 10 s = 5 km of effective range.

Supposing you can launch early enough so that the missile can fly 30 seconds, in that case the 500 m/s gives you 15 km worth of effective range.


Now take that target and turn it around so that it's flying away from you. Now the relative speed it's contributing to your missile is - 280 m/s.

Over 10 seconds that's 2.8 km less range, over 30 seconds that's 8.4 km less range.


So compared to the first scenario, there's up to a 23.4 km difference in effective range, just based on what direction the target is flying.


There is no single range. Range depends on a bunch of variables.


When looking at wikis or books the range figure is often the manufacture's listed figure, which is often a number optimized for selling as many missiles as possible.

Ranges at which missiles can hit in realistic situations are normally drastically shorter.

A couple quick questions:

1-Would carrying 6 RVV-AEs, instead of 2 R-73s and 4 R-77s, be an okay loadout? Y'now, to get more bandits at BVR?

2-Is trying to engage 2 targets, as long as they're not competent fighters (like, say, UAVs, bombers, attack aircraft) be worth it?

Sure, if you can load them... As long as you never let a BVR fight transition into a close-range knife fight. Otherwise you'll wish you had those two R-73s.

Default 1,620km/h!!!

Not really related, but I just hit 1,620km/h in the MiG-29S! Of course, the canopy was off, no external stores were being carried (not even ammo, chaff, or flares), the landing gear, flaps, and airbrake were all retracted, the computer was yelling 'maximum speed' at me, and afterwards, either the engines turned off, or I ran out of fuel (which would also result in them turning off). Still, I think 1,620km/h counts! Do any of you agree?

FWIW, the max kinematic range I've seen in the sim is around 82 km (track attached). The problem, of course, is that this range exceeds the radar's ability to provide a lock (on a DCS aircraft with enough speed to produce these ranges). So you won't be able to launch until around 60 km. And, at the speeds involved, the missile will have only traveled about 40 km before the kill. All of which illustrates just how "slippery" a term "range" is, when talking about missiles as others have indicated.

We talking IAS or TAS? I have to admit, that's pretty impressive, if we're talking IAS. Though there's still room to grow...
