    One thing I've noticed after flying around abit: When looking at the controls indicator in the upper left corner, it appears I'm mostly never allowed full rudder/yaw deflection, that is when I apply full left rudder the indicator on the upper left shows me only applying 60-70% of that. Why is that? I've often been unable to apply the required amount of rudder to execute a maneuver because of this artificial limit to my inputs.

    That's what it's supposed to, but I've yet seen it happen online with jester in the backseat.

    I am talking about the WCS being able to store a track and send the active signal when the missile reaches the predicted location of the lost target. You can do this with a human RIO atm, but not with jester... Atleast not in my experience. Lose TWS track with jester, and the missile is dead.
  4. Hummingbird
    Of course he can, all he has to do is keep the extrapolated track and send the "go active" signal where the AWG9 predicts the target will be based on the previous info, but instead as soon as a track is lost jester switches back to default so the missile never goes active.
  5. Hummingbird
    I wish Jester was smart enough to do that...

    At 1310m the spread looks pretty tight, first rounds seem right on target: The targeting & tracking system probably recieved many improvements since 1995.

    Kind of yeah, it would be better to for example say NIIRS 7 at 2 km.

    I'm not a fan of tacview, as I find it often contains error readings. Hence why I only do measurements using the infobar. As you can see in the video attached, 9 G is not sustainable at 450 KTAS (448-449 KIAS) in the actual simulation. Best I can for sure get here is 8.8 G. So my assessment is the F-16 still needs some minor tweaking of its STR before its right where it should be, being in general 0.1 G off. As pr. NineLine's previous post ED is perfectly aware of this, so I definitely expect further tweaking.

    Quick test at 450 KTAS to show it cannot be sustained. Note: 450 KTAS is 448-449 KIAS.
  10. Hummingbird
    It's impossible to hold 9 G's level at 450 KTAS atm, so Im wondering how you achieved that. Infact this is the easiest speed to test, because as soon as you hit 450 KTAS full back stick is needed to achieve 9 G, and it cannot be sustained. So something must have gone wrong in your testing. Did you forget to put on infinite fuel? I'll post a 450 ktas test vid soon to illustrate it.

    Alright, finished the testing of the F-16C: DCS F-16C, 22,000 lbs clean, ICAO Std. day 15 C, Sea Level (40-75 ft): 215 KTAS (M 0.325) = 3.4 G vs 3.4 G chart (0.0 G) V 250 KTAS (M 0.378) = 4.1 G vs 4.3 G chart (-0.2 G) X 300 KTAS (M 0.453) = 5.3 G vs 5.4 G chart (-0.1 G) X 350 KTAS (M 0.529) = 6.5 G vs 6.6 G chart (-0.1 G) X 400 KTAS (M 0.604) = 7.7 G vs 7.7 G chart (0.0 G) V 450 KTAS (M 0.680) = 8.8 G vs 9 G chart (-0.2 G) X ED's own internal testing should confirm this, but here it is for everyone else. A little more tweaking, and we're there. Footage of one test run at 400 KTAS (Ran 10 seperate test runs at each speed, so 60 test runs in total over 2 days), this one wasn't the prettiest of the 400 KTAS ones, it taking some time for me to get settled near my target speed and alt, and thus the best readings were somewhere near the end, but at least this gives some insight into my approach: Note: In this run I try to settle around 398 KIAS as best I could, as that is 400 KTAS according to the infobar.
  12. Hummingbird
    @NineLineWill there be further adjustments to the STR for next update? As we're still lacking some performance on either side of 400 KTAS.
  13. Hummingbird
    That doesn't have anything to do with G-onset, but yes the F-14 can, and did in reality as well.
  14. Hummingbird
    Yeah, it obviously depends on the distance. I think the 64D uses 2nd generation FLIR sensors, so it should be quite high resolution out to a long distance.
  15. Hummingbird
    For anyone wondering: https://irp.fas.org/imint/niirs.htm
  16. Hummingbird
    The F-15 has a very high G-onset rate because it has no FLCS AoA/G-limiter restricting stab movements, it's the same with the F-14, F-5 etc, they can also achieve the same very high onset rates because of this.

    Not intending to start a math battle, just wondering why he thinks you guys got the speed of sound wrong in DCS.
  18. Hummingbird
    That makes more sense, was wondering why it read 24k lbs. Like I said, ICAO ISA, speed of sound = 340 m/s. You can use this calculator from NASA's site: https://www.grc.nasa.gov/www/k-12/airplane/sound.html Now why do you believe the speed of sound in DCS is 345 m/s at 15 deg C?
  19. Hummingbird
    Often its hard to get the rate scale to fit precisely on a doghouse plot like that, hence it's better to use the measured load factors. Seen it on F-14 & F-15 charts as well. The actual turn rate at M 0.695 @ SL (which is 236.5 m/s under ICAO ISA) when the load factor is 9 G, is 21.24 deg/sec. Turn rate = 9.8*(sqrt((load factor^2)-1))/velocity
  20. Hummingbird
    *facepalm*
  21. Hummingbird
    Simple, base your calculation on measured load factors, and not the calculated turn rates which are often abit inaccurate. Hence why I always compare measured & charted load factors at specific speeds, never turn rates. If I want precise turn rates, I calculate it based on the actual measured load factors.
  22. Hummingbird
    Refer to here: https://www.grc.nasa.gov/WWW/K-12/airplane/airprop.html The speed on the EM charts is in True Mach Number under ICAO ISA. You even get some nice small graphs with corrections for variations in temp from std. day. Std. day conditions haven't changed since 1966 AFAIK. To quote: "The ISA models a hypothetical standard day to allow a reproducible engineering reference for calculation and testing of engine and vehicle performance at various altitudes" Without this standard frame of reference EM charts would be pretty pointless.

    Simply use the ctrl + y infobar, press it twice and you get TAS. My question is why you think the speed of sound in DCS is 345 m/s at SL at 15 deg C and 333 m/s on the charts? The charts show performance at ICAO, that is std atmosphere, 15 deg C at SL, where the speed of sound is 340 m/s, not 333 m/s. Furthermore the speed on the chart is listed in TMN. So I don't understand why you find the need to do any calculations.
  24. Hummingbird
    I'm talking about DCS.
  25. Hummingbird
    Are you sure? It shouldn't be if you use ICAO at 15 deg C.
