Static thrust does not depend on speed and T/W ratios, from what I know, are given for max static thrust and max TO weight. What @bkthunder was refering to is that static thrust (or near it) might possibly be underperforming. This would manifest it self in straight accel. as lift in this case does not play a big role in drag, where as in turns it does.

A this point max. we can do is to report and hope for the best. Would be great if you can share some critique on the test methods. If I remember corectly you have a background in aerodynamics. Our preliminary results show a difference that is close to 20% compared that of the manual.

+1 for the tracers I like killing my enemies without warning.

Oh so it's behaving like the R-77 now. No need to fix, if you ask me - for consistency sake

Ah I see. This is not what I was talking about.

I was not aware. How does one perform this?

I will see myself out.

Comparing engine thrust from the manual to real-life performance In this RL MiG-29 takeoff video, it takes a Fulcrum weighing around 13300kg 14000kg (11000kg EW + 3000kg fuel) to accelerate from 100km/h to 200km/h around 3.76s at MIL power (max dry thrust), which gives an acceleration of around 7.39m/s^2 and calculated thrust (per engine) of around 5010kgf 5272kgf. This is slightly above what manual states This verifies the value from the manual which states that at MIL power, each engine should provide 5040kgf. I guess now it would be a matter of performing the same test in DCS now. JavaScript code used for calculations: const g = 9.81; // m/s^2 const m = 14000; // [kg] const framesToSecond = frame => frame / 25; const kphToMs = kph => kph / 3.6; // 00seconds:00frame const deltaT = (t0, t) => { const time = t.split(':'); const time0 = t0.split(':'); return (parseInt(time[0], 10) + framesToSecond(parseInt(time[1], 10))) - (parseInt(time0[0], 10) + framesToSecond(parseInt(time0[1], 10))) }; const dt = deltaT('02:03', '05:22'); const v0 = 100; // [km/h] const v = 200; // [km/h] const a = (kphToMs(200)-kphToMs(100))/dt; const f = m * a; const thrustEngine = f / g / 2; console.log('It takes MiG-29 weighing ' + m + 'kg, ' + dt + 'seconds to accelerate from ' + v0 + 'km/h to ' + v + 'km/h.'); console.log('Acceleration is ' + a.toFixed(2) + 'm/s^2. Single engine thrust equals ' + Math.round(thrustEngine) + 'kgf.'); Output: "It takes MiG-29 weighing 13300kg, 3.76seconds to accelerate from 100km/h to 200km/h." "Acceleration is 7.39m/s^2. Single engine thrust equals 5008kgf." "It takes MiG-29 weighing 14000kg, 3.76seconds to accelerate from 100km/h to 200km/h." "Acceleration is 7.39m/s^2. Single engine thrust equals 5272kgf."

You forgot to mention, ground controller endlessly repeating: "Hold position". That's my favorite

What is slew-able on the real thing is the scan zone center, as there are wide and narrow scan widths, with narrow one having slew-able center. In wide mode the scan cycle should be 3.5s and in the narrow one 2s. The same buttons used to slew the radar antenna, are used to slew IRST when in narrow search field.

Good catch, all the videos in this thread show F-14 as the target.

How the hell can a missile climb with a G load of 0.6? Was this recorded in deep space?

From what I know 100% of A2A missiles in DCS use some sort of homing - IR, active radar, semi-active radar. DL is used to bring the missile to the point where it's seeker can pick up the target and after that home in onto it, with the exception of IR ones of course. ARH missiles are only "fire and forget" if their radar already is in range, which in DCS is I believe 13-15km (could be wrong on the actual numbers). They only true "fire and forget" A2A weapons are IR missiles. Note: I am not talking about A2A passive guided radar missiles as we don't have those in DCS.

Would be great if you could share some of the material in its original form. Also very interestingly, what happens if there are multiple targets in close proximity and the launching platform that is providing the DL suddenly switches to the wrong target, while the AMRAAM is tracking the correct one? Should it follow the DL or ignore it? If the DL alone could guide the missile to the target, there would not be any need for homing.

Isn't the NEZ based on kinematics (dynamics) rather than seeker?

I guess this is what happens when there's blue on blue fighting going on. I haven't flown DCS for 2-3 months, so I can't really judge but as I am usually on the receiving end (flying red), to me Slammer feels like a laser most of the time.

I see, that's interesting. I could be totally wrong on this one, but I doubt DL will be accurate enough to get the missile close enough to the target without homing, but I guess it supplements the missile's radar.

Real life pilots can pre-strain before pulling G loads, which allows them better tolerance then if they just re-actively responded to increasing normal load. Would it make sense to assign a button that would initiate fore-mentioned behavior in DCS? For example (G-load numbers are arbitrary): one pre-strains and the G-LOC is at 9G, one doesn't and G-LOC happens at 7G. This would really separate men from boys, IMHO.

Thanks a lot for the screenshots. Are you able to replicate this issue in Single player also? I've once had 4xR-73 and 1xR-27T miss in multiplayer from 6-12km distance, so I'm wondering if it's something to do with MP. Yeah that one should def. have tracked the target.

Pardon my ignorance, but isn't this how it's supposed to work? From what I understand, DL is there to give the missile mid-course guidance until it's own seeker can pick up the target and guide autonomously.

Please forgive me if I am missing something obvious, as I can't view tracks at the moment, but no one here actually provided "expected behavior" to "current behavior" comparison like: "What is AMRAAM doing as opposed to what it should be doing?". A lot of people just started saying "ah it's not like it used to be". Could you please provide some info/theory that backs up the claims? I am not saying they are wrong per se, just that there are no facts being put here, a part that "it ain't what it used to be." Someone here mentioned that turning cold breaks the lock, well the same happens on a much larger and more powerful radar system found on the airplane, so I guess that shouldn't be an issue.

How's the missile's and/or airplane's radar supposed to discriminate targets in a fur-ball? Positions and speeds are dynamically changing all the time.

Could you test the max AoA without thrust? It seems to me that vertical component of thrust might be keeping the airplane "hanging" in the air.

They should be identical.
