      • While the TGP hangs from the RHS chin hardpoint, the image actually comes from the left. Although the TGP can still track on the right hemisphere, so the bug isn’t that bad.
      • I know the laser is supposed to be on when pressing the pickle button, but sometimes doesn’t stop illuminating after bomb release and stays on. Bombs dropped when that happens usually miss the target.
      • Medium-high altitude tossing calculations don’t work. The bomb flies waaay past the target.

        What height are you dropping Lgb`s from ? If you have lase time set at 12 secs or more and the lase comes on at once or almost then maybe you are too low for that lase time. Just a guess. You will probably say you were at 20k+ then it must be some other issue.

          I know what you mean. I’ve tried at many altitudes, but can’t find a direct relation. Sometimes I use a lase time of 10 secs and get a time of fall of 40 secs, and the laser is on all the way.

            The laser being ON all the time should not make you miss, quiet the opposite - it should make you more accurate

            Use TACVIEW and look at your ACMI and see how much you are MISSING by are you close or are you a country mile away?

            Are you flying with an AI who is lasing targets in the vicinity of your target? and thus using the same code?

              IIRC, laser on from drop makes the bomb steer out of ballistic flight too soon and lose some performance.
              I’m flying alone, no wingmen around messing things up. I’m missing the target by almost half a mile, just like when dropping the bombs without lasing at all.

                Lase being on in early seconds of bomb flight can cause miss. At least in RL with some Lgb`s Believe the latest paveways not such a problem.

                @ Huesudo You always remember to select combat mode ? Probably yes as I don’t think it flashes in Training mode now I think about it.

                  I have the same problem. Me, others friends try but, sometimes laser flashing and the bombs don’t hit the target. Laser combat, code set… and I think a bug…

                    Are you lock up the ground target of the FCR and then switching to TGP to and using laser ?

                      No, no lock with Fcr. I use only the laser with area or point. After the release, if L flash automatically, don’t hit the target. I use falcon from 99…this problem I see only now, with upd3.

                        Laser is in CMBT mode correct? That has changed, you have to set it using the ICP or it will be in TRNG and the bomb won’t guide.

                              ok, now works….i don’t considered the clouds. I read manual and page 93…clouds can masking the laser… and now, with heavy weather, the fun is max! ahahah love falcon 4 😉 thanks at all Cheers 🆒!

                                Something must be wrong with the GBU-24. I was testing with GBU-10s and 12s, and even when the laser is on all the way, they hit the target. 24s on the other hand sometimes miss by a couple thousand feet even when everything works as it should.
                                Laser is set to combat, with a lase time of 10 seconds. Weather is clear with no clouds. I’m doing the tests without wingmen.

                                  Try setting laser to 16-20 seconds. Different bombs have different flight characteristics, they don’t all fall or guide in the same way, and what works for one doesn’t necessarily suit another.

                                    GBU-24 (LGB III) is gliding WAY further naturally than LGB II (GBU-10/12), so 10 seconds won’t do, by the time it gets to 10 seconds the bomb is already too close so it can’t pick the laser spot (lookdown angle limit), you must lase earlier.

                                    Also, advice from me, get used to lase MANUALLY with the trigger’s 1st detent, this is how it is done IRL.

                                      I have experienced the same thing. It happens when the laser does not stop flashing after pickle (no matter what laser time is set, I’ve tried 10s, 16s, 24s… when the bug occurs it doesn’t matter what duration is set).

                                      In order to get rid of the bug I have reinstalled BMS and it may have solved the bug though its randomness make it difficult to track.

                                        Guys, regarding laser getting stuck, there is another thread going on for the same issue, I need you to do one of 2 things:
                                        1. See if your problem is same as I explain in that thread: https://www.benchmarksims.org/forum/showthread.php?29879-Laser-permanently-lasing-after-short-manual-lase
                                        2. See if you can get me a way to reproduce the laser stuck issue. I confirm that I’ve also seen it sometimes but I can’t reproduce it, and without reproducing, it would be very hard to nail.

                                          I guess that if you begin lasing too early, the bomb should go straight away to the lasing point, in a flat trajectory, without completing its necesary curve ballistic trajectory, so risking falling short.-
                                          Please somebody confirm this

                                            It depends on the bomb.

                                            Taking the two most common US types, the older Paveway II bombs (e.g. GBU-12) have ‘bang-bang’ guidance, which only steer with full deflection of the control surfaces. This method of steering bleeds energy as they oversteer first one way, then the other. Lasing too early will likely cause them to fall short. 16-20 seconds in BMS is plenty long enough, assuming the bomb is dropped within parameters.

                                            The newer Paveway III bombs (e.g. GBU-24) have proportional guidance, so can fly a much more efficient path to the target. Lasing early (or manually) is actually preferable as the bombs will fly long if they can’t find a laser spot to guide on and may be unable to lookdown enough to pick it up if autolase is set too short, as I-Hawk wrote above.

                                            Personally I have autolase set to 20 seconds, which I find long enough for IIIs (if I don’t manually lase) and short enough for IIs.
