Question regarding GMT STT or TGP point track.

[RPY Variable]

Case 1: If I see a moving ground unit with the ground radar on GMT mode and I STT it. Then I CCRP any bomb, the bomb will hit where the unit was at the time of the release, the system will not predict the unit location based on speed and direction.

Case 2: Same as above but using the TGP on point track. The bomb will hit on the location of the moving unit at the time the bomb left the aircraft.

Is this the right behavior? Shouldn't the computer simply predict the target location based con speed and direction? The computer already knows where the target is going, in what direction, and how much flight time the bomb will have. Seems illogical to have so many systems (radar, gps, ins, laser, etc...) in other to gain those three parameters and then don't do a simple formula to get the impact on the actual target location.

"FTT" and "MTT" are for ground locks but yes, no motion prediction for aiming. Same for any senor.

I have another question regarding the same matter. Is there a way of making the TGP follow the GMT lock like on the jf-17 instead staying fix fixed at the floor where the vehicle was at the moment of the TMS up?

HI.

You will have to steer the TGP over the target and TMS up it so it will follow the vehicle. Do it fast or the vehicle will drift away pretty soon! In another thread I read that it is probably a bug, as the F/A-18 can automatically track the target, but I m not sure of this.

Yes, but when I TMS up on the TGP it is no longer a STT on tgt... it is a point track. I suppose it should be like an STT lock on an aircraft, where the TGP follows the aircraft, when it is on a ground moving target it should follow the vehicle.

I assume it is a bug, but unfortunately I don't have my personal F-16 to try it myself.

"STT" only refers to the radar and only against air targets. No such thing as STT/FTT/MTT for TGP, those are radar-only terms.

When the TGP is tracking and SOI (AG preplanned context) it must be the master sensor and the HUD TD box and FCR radar cursors must follow continuously. If the radar is tracking (slewed search or FTT/MTT) and SOI then it must be the master sensor and TGP must break track and slave to radar LOS. The TGP/HUD TD box/FCR are always, always, always sharing the same line of sight. This is a core and fundamental design concept of the F-16. If the simulation is doing anything else then it's wrong.

There is an accepted bug report about this wrong behavior.

I also tried with moving ground and sea targets, the radar doesn't transition to FTT with TMS up, it always goes to Freeze and marks the coordinates of that spot.

I think someone read a document wrong. By entering PPI FTT with "frozen ground map picture" someone took it to mean that it enters freeze mode. Right now we don't have FTT functionality.
