bob_baer Posted January 5, 2017 Share Posted January 5, 2017 Does anyone know why it's recommended to lase not earlier than 8 - 9 seconds before impact? I would lase from the beginning. Doesn't it improve accuracy guiding the bomb from the beginning? Inviato dal mio iPhone utilizzando Tapatalk Link to comment Share on other sites More sharing options...

Inviato dal mio iPhone utilizzando Tapatalk the bomb overcorrects as it falls, and the amount of correction it does is a function of it's distance from the target. if you lase too early it can overcorrect and lose the laserspot, at which point it will fall ballistically and miss. this may not actually happen in the game, but many sim recommendations don't really pan out in sims.

cthulhu68 Posted January 5, 2017 Share Posted January 5, 2017 I thought 12 seconds before impact is recommended. I believe the reason is when a bomb is dropped its hurling forward at high rate of speed and can't be controlled very well. 12 seconds before impact it should be coming down close to vertical and easier to guide.

Xavven Posted January 5, 2017 Share Posted January 5, 2017 Somewhere between 8 to 12 seconds before impact, depending on your release altitude above ground level, is the optimal time to use the laser. Your bomb will miss short of the target if you lase too early. Before you use the laser, a GBU-12 or GBU-10 falls in a ballistic trajectory (approximately a parabola). Once you fire the laser and the sensor acquires it, the guidance system tries to fly straight towards the laser spot and doesn't attempt to account for its speed or altitude. When you lase too early, the bomb bleeds off all of its energy early in its flight, begins losing altitude, and then has to pull up as it nears the ground, and often it doesn't have enough energy to maneuver at that point. I'll see if I can demonstrate this in Tacview. I see this question come up periodically in the forums. Link to comment Share on other sites More sharing options...

Inviato dal mio iPhone utilizzando Tapatalk RL, AFAIK, the paveway I and II only have max deflection, so if you lase to early, the bomb can stall and not reach the target. Paveway III (like the GBU-24/27) the actually should benefit from a longer laser time. Also, the pod has limits on laser time. Each pod is different. In DCS, I do not know. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true.. Link to comment Share on other sites More sharing options...
Deezle Posted January 5, 2017 Share Posted January 5, 2017 (edited) I've never found there to be a problem lasing for as long as I want in DCS. You can watch the bomb fall, it absolutely will not track the laser sooner than 15 seconds from impact, every time, no matter what. Dropping from too low is certainly a problem.

Vitormouraa Posted January 5, 2017 Share Posted January 5, 2017 I always use 15 seconds and I've never had any problem with that. It works just fine! SplashOneGaming Discord https://splashonegaming.com Link to comment Share on other sites More sharing options...
al531246 Posted January 5, 2017 Share Posted January 5, 2017 My rule for GBU-12's; - 10 seconds auto-lase 99% of the time - 15 seconds if windy conditions Intel i5-8600k | EVGA RTX 3070 | Windows 10 | 32GB RAM @3600 MHz | 500 GB Samsung 850 SSD Link to comment Share on other sites More sharing options...
Yurgon Posted January 5, 2017 Share Posted January 5, 2017 I read just recently in "Flying the F-15E in the Gulf War" that the very first LGBs dropped by F-15Es used to fall short if they lased too early. At the time, the TGP's integration was basically in an experimental state and crews had not trained to use LGBs before they went to war. Later LGBs apparently didn't suffer from this problem. This was still '91, just later in the war. I'm beginning to suspect that the advice to only lase during the last 10 to 15 seconds in DCS is based on heavily outdated information. In any case, most players who responded on this topic said that their LGBs never miss if they lase right after pickle, even if they drop from high altitude (at medium to low altitudes, the seeker wouldn't pick up the spot early enough to change the flight path enough for a ballistic miss anyway). My personal SOP is still to lase during the last 10 to 12 seconds before impact; among other reasons, this limits the time of illumination and might help to prevent buddy lasing problems if several aircraft use the same laser code while dropping in the same area at close intervals. My hit percentage is near perfect with this setting. Link to comment Share on other sites More sharing options...

My hit percentage is near perfect with this setting. just a theory but for the A-10 it probably matters less than other platforms. the reasoning for this is that A-10 releases closer than all the other PWII carrying jets. the reason for that is because the A-10 is slower and tends to release at a lower altitude (IE, has less slant range to the target) since the seekerhead tends to correct more violently the further it is away, it might actually be possible to cause misses if you are in another jet and going fast. in A-10c though you're right and you will never miss even if you start lasing the moment the bomb departs the airframe.

Kang Posted January 5, 2017 Share Posted January 5, 2017 Actually one might try that out in DCS by having an A-10C buddy-lase for a Mirage, for example. Link to comment Share on other sites More sharing options...
Jafferson Posted January 14, 2017 Share Posted January 14, 2017 Or may be lasetime is to decrease the respond time of the target, to lower the chance of survive. First 2sec... Target recognize the laser 4sec... thinking... **** we get lased, a bomb is on its way! 6sec... "Hey bro we get lased a bomb is on its way!" 8sec... What??? "Run!!!" 10sec... Splash!

mkiii Posted January 15, 2017 Share Posted January 15, 2017 I think 15 seconds notice that your vehicle is about to get bombed probably isn't quite enough time to make a decision, get out and then run a couple of hundred metres to get out of (the worst of) the blast zone.
