GBU Guidance and Laser Designators
-
Okay, so now I have a whole new set of questions about Buddy Lasing:
How does MY F-16 know when the bomb drop should occur if my buddy is lasing the target?
Somehow my software must be aware of the target to calculate and display the steering and targeting information on my HUD, correct?
As I see you simply do nout understand what it means laser guidance. It is literally terminal correction to eliminate the CEP of iron bombs. So the buddy lasing it wors as way that you tell the bomb which laser beam - based on FREQ - should be aimed, the buddy lasing aim the designated target and the LGB platfrom aim as close to that point with any bomb aiming mode as possible. For make easier the aim some AC has or had laser spot tracker for ex. as Pave Penny on A-10. As I know TGPs also can act as laser spot tracker in case even the TGP carrer AC supported by buddy lasing.
(It is strange that literally all of comments are always carriers neative meaning…)

No there is no DL and no nothing, it’s passive guidance on laser beam, so no the TGP doesn’t know when the bomb picked up the laser spot. You just drop the bomb, lase and hope that the bomb will pick up the laser spot (assuming you did everything OK, it should work…). TGP itself has special LST mode in order to lock on an active laser spot in the area of the sensor.
And BTW, for the OP… I suggest you to make it a habit to lase manually using the 1st trigger detent, as soon as you think appropriate. Although auto also works, in RL AFAIK manual lasing is used.

Fixed that for you. 2nd detent will be firing the guns.

In this case, Training is an eye-safe mode for training (ie : exercising) pilot for laser operation. I think (not sure) that is the mode the laser is using for basic telemetry data too.
The only laser mode in BMS is Combat. IRL, you need Combat laser to guide a bomb, anyway. Training lase does not reflects enough energy for the bomb seeker to detect it.
I assume the CCRP needs slant range to compute when the bomb is released . Can the laser be used? or does it need AGR?

yes, the laser can be used for slant range. The laser IIRC is a higher priority sensor than the FCR for determining slant range.

Thanx! I changed my post

Yes but in real only if you are in guns mode, what we have currently in 4.32 is wrong.
-
I can only fire the cannon in dogfight mode if I’m not mistaken.

You can also fire the gun in A-G mode if you select the gun on the SMS, and also in A-A mode with a similar caveat.
Im not sure what part of 4.32 is incorrectly modeled according to I-Hawk?
-
What happen if you trigger 2nd detent just like that? will the gun fire or not?
-
Not mine, but I have “triggerseconddetent” as callback, there is a callback “fire guns” too, but that does what you describe iirc.
Cheers

For me, I can have Master Arm ON, but if I am in NAV mode then pulling the second trigger detent still does nothing.

how is that possible when the laser fires the 7sec before bomb impact.

Forget about auto lasing… people should get used to lase manually… in RL the lasing is always manual AFAIK. So with 1st trigger detent you can lase whenever you like.

So, if want to TGP MARK pt, GPS coors or a CCRP cue, in r/l, you need manual lase mode, pull the trigger.
-
Auto-lase trigger is only for ownship bomb fall timer. All other functions (buddy lase, range finding, cooking chicken at a distance, etc.) is manual activation.

More exactly : IRL, if you want one of these things accurately, you need to pull the trigger.
Otherwise the systems computes something either based on training laser rangefinding, or if it finds this unreliable (weather, whatever) radar slant range in the TGP direction (if available), or based on your barometric altitude. I dont know if it is able to know target altitude, so that makes the last one kind of ballpark.

for targeting, if the system falls back to barometric altitude, then it assumes the target is at the same altitude as the STPT.
how is that possible when the laser fires the 7sec before bomb impact.
IF the laser is active, then it gives the system high accuracy slant range information. When the laser is deactivated again, it reverts back to the next highest priority sensor.

Baro get it close. At 6000msl 45* slant angle SPI is off ~1nm. Could be “danger close” issues.

I made my first flight since January the other day (bought me a cougar and dx’ed it) so my memory might be a bit off.
But I think I used to use auto and 12sec for laser, and it was because the manual laser by first trigger wasn’t bulletproof. I think it had to do with if I pressed and released the trigger and pressed again, the bomb didn’t pick up the laser the second time.
Again, I could be wrong.
