  1. This bomb should fly almost horizontal when dropped at speed. In DCS it is just a normal GBU with a slightly attenuated parabolic trajectory. If you want to have a more or less decent distance you need to drop, let's say, mach 1.2 35.000, and it almost goes on a 45° dive to the target, which goes against the essence of this bomb. In DCS it has a glide ratio of 2.5 or less, which is ridiculously low if you compare it with this video and common sense.


    Note that the bomb drops like a normal bomb, then the autopilot kicks gliding with a much more shallow angle. Int not going to make a CFD study of the bomb, but 2/2.5glide ratio (, when dropped at 500kn, seems way too low.

  2. 1) The effect seems to be too sudden. Today I black out on almost all merges.

    2) From changelog: "This is most useful AFTER performing a G warmup (4 to 5 G for 90-degrees, and then the same maneuver back in the other direction)." Why 90° in one direction, and then 90° in the other direction??? I find it kind of arcade. Like if matter which side you are pulling, there is no difference for the body. For example, G-Force centrifuges only rotate in one direction. In my opinion it should be, X amount of G's X amount of time and that's it.

    That is utter speculation and there is no substance to that statement. I'd look forward to your evidence that HB would do such a thing beyond your interpretation.

    I actually think the release of the F-4 will make the F1 even more popular. Currently there isn't a directly comparable 3rd gen aircraft to the F1 in DCS, with the CE being a mid70s vintage. The F-4E that we get is early 70s, and aside from being a more complex two seater, have similar capabilities. I suspect people will jump in to the F-4 and become naturally interested in trying other aircraft, and most particularly the likes of the F1 and future MiG-23. Principally because the Mirage and Phantom complement each other in terms of gameplay - not compete. The presence of both serve to greatly enrich the Cold War gameplay potential DCS has. 

    I am talking about the reason for the hasty announcement of the F-4 and you are talking about the effects that the launch of the F-4 will have on the sales of the F-1. They are two different things. Beyond that I don't agree either since it is like saying that the Toyota Corolla does not compete for sales against the Honda Civic.

    Had I known that the Phantom will be delayed so much, I would have bought it already. I figured two complex planes (for me, I’m a warbirds guy) will be too much to learn in parallel. F1 is definitely on my list now, and the moment I’ll be ready for another jet module, this is going to be it.

     

    That is precisely why they announced the F-4 just when Aerges was about to release the F-1. With the promise that the F-4 would be available before the end of the year. In this way, they induce several people not buy the F-1 and wait for the F-4... in the end, the wait turned out to be more than two years, but they achieved their goal. These are the rules of the market, but a very unhappy move if you ask me.

  5. ED degrades RED coalition GPS accuracy. So take that into account. If you drop a gbu-38 from a BLUE F-16 you may have a CEP(circular error probable) up to 6m, if you drop from a RED F-16 you will have a CEP up to 50. You will have a better accuracy with a dumb bomb CCRP release. I didn't test if it affects J-17, but I suppose it does.

    You may need to hit TMS down twice.  First time seems to "unlock" it from something, 2nd time seems to recenter it on the steerpoint.  No idea what the correct behavior should be, but TGP slewing messes with the nav system steering cues so much that I'm now just making sure to hit TMS down several times before going back to Nav mode, after changing steerpoints in AG mode, etc.

    Hit it 10 times, it does the same thing. I think is broken.

    Hello all

    After we reviewed the tracks and observed the conditions, we believe we have found the culprit for your reports.

    It's actually a feature in DCS, regarding GPS quality.

    In your track @RPY Variable your F-16C is set to the Red Coalition. As such, the GPS quality is by default much lower than the Blue Coalition. In order to mitigate this, you can select "unrestricted sat nav" option in the Mission Editor or just select a Blue coalition side. 

    I tested this myself with the DCS: F-16C Viper and with the DCS: A-10C II Warthog and you can observe the difference. 

    Without proper or poor GPS guidance, the GBU-38 can have a CEP at about 30m or even more. So this is actually well modelled.

    Thank you for your patience and, yes, this was a tricky one. 

    Thanks for taking the time.

    I understand the argument, I don't say I agree (don't think anyone cares), 30 meters of precision seems a lot to me no matter how bad the GPS is. Even more so with such unverifiable aspects as GPS guided accuracy of eastern world countries. Maybe if BLUE is 5m, then make RED it 10m or 12m, I don't know, but 30m, 40m even 50m seems like much. It is worse than dumb bomb level flight release from 20.000ft.

    Be sure to stick this report on the refrigerator door because it will surely be a constant complaint XD. Thanks again for the time.

  8. I start with a waypoint over a tank (altitude of the waypoint is as the tank). The TGP point over the waypoint, when I slew the TGP and press CZ, the TGP doesn't go to the tank, but if I do a combination of SP->CZ sometimes it goes to the tank. But if I slew from there and CZ again, it again goes over the tank.

    Sames happens if I do it over a mark-point.

    Shouldn't the TGP start pointing over the tank, and CZ always go to the tank.

  9. I release there because I was prepared for someone telling me, "you release from very far away and the bomb had poor energy"... nevertheless. They had plenty of flytime.

    Based on what has been shown, I don't see any debate.

    Next image is Mk-82 dumb bomb release on level CCRP, same altitude, same all. Almost same accuracy as gbu38.

    This is nothing new, it has been like this for quite some time now.

    Please ensure you are using the laser to get the correct range for the target, this will ensure the CEP is much smaller. 

    thank you 

    Why so fast with the  "correct as it is"? This has no sense.

    1) If there were drift between the target and the waypoint, for example 30 meter to the left, the bomb should fall away from the target (+-30m to the left), but with the same CPG. All bomb should fall near each other, because there is an offset, but the bomb accuracy (CPG) shouldn't change. Image attached showing what I mean.

    2) The waypoint was in place in the editor, the mission was just started, so there should be no error, and what shows that there is no error is the TGP pointing to the tank, which was CZ, it was not slewed at any time. In this case, it should work as a B2 with preplan waypoints. Is a INS/GPS bomb.

    3) They are also very apart in azimuth, so it not a distance (laser) thing.

    4) I tried with lase, almost same result. Image attached.

  11. 1) Why sometimes I'm able to get my selected waypoint showing on the RDR screen and sometimes not?
    2) Why sometimes I'm able to get the lines between waypoints shown on the HSD and sometimes not?

    If any JF17 veteran is able to clarify my doubt, I would be very grateful.

  12. I don't know where the "the gun is tilted down specifically to target ground targets" myth came from. But people keep repeating and repeating... The gun has the angle that it has because it is located under the fuselage, so it can't be tilted up, like in western fighters to gain more lead. It is the same arrangement of the mig-21 and nobody is repeating that mig-21 "the gun is tilted down specifically to target ground targets". Or the F-4, again mounted under the fuselage, and tilted is tilted down quite a couple of degrees.

    Not very clear at all, I'd say ED took the safe approach here with using the FCR range scale, I don't know why they didn't keep the ability to change the range scale while in EXP/DBS modes since before it worked similarly to the F15E's MAP mode in it's A/G radar, we can obtain similar results by moving the cursor to the area using TMS up to save the area and then changing the RNG scale, and going back into DBS,it works fundamentally the same as in the videos by wags just that you need to re-enter the DBS mode after changing the range scale. Can't really tell if that's intended behavior or not.

    The only thing I can say is that it is a pain to use like it is now. Before (wags video) was great.

  14. I've made a couple of post's of this behavior, which is logical and cumbersome. The manual doesn't specify whether the image resets when changing the scale or not on EXP, DBS1 or DBS2. That just guessing. It is difficult to imagine that the engineers ended up with a complicated behavior as this. The wags video seems to have more sense.

    The F-16 block 50 manual says that it DBS2 -> "the patch varies as the cursor is moved in range" but is a little ambiguous, I don't know if it refers to the TDC cursor distance from the aircraft, and it automatically changes size, or it refers to the FCR selected range scale.

     

  15. Example: Lights Console + Lights Panel, all controlled with one axis.

    Example 2: Com 1 Volume + Com 2 Volume, again, all with one axis.

    This would make our controllers perform much more efficiently. I have 9 exes without counting the pedals, joystick and the two throttles, and I always fall way short... and I'm only trying to map the bare minimum, like lights and a couple of volumes.
