Avio Posted 8 hours ago Posted 8 hours ago I created a mark point for a target, came in using CCRP high drag bombs, only to find the mark point to be a little off from the actual target. This happened at Sinai map. Anyone else noticed this before? Is it a map coordinate issue, or the F16 mark point issue?

Depending on the direction you came in from when you placed the markpoint initially it will appear slightly off if you come in from another direction.

F-16 only has a GPS-corrected INS, not a full Enhanced GPS-INS (EGI) navigation system. So when you make a mark point, it's an offset based on the INS present position. As you turn, especially for sharp maneuvers, the INS will drift, and with it, your markpoints (and really every waypoint, coordinate, and such in the jet) will drift as well, moving them off-target.
Avio Posted 4 hours ago Author Posted 4 hours ago Thanks much folks. I was under impression the GPS/INS in F16 is similar to the EGI in the F15E, which gives exact location plotting. That being the case, does it mean for JDAMs they would all hit a little off from targets too? Or they should be spot-on since they are guided via satellite GPS?

Can we do anything in flight to combat this drift? I know of FIX and A-CAL options on ICP. Should we re-align INS in Air mode ?

JDAM will already hit slightly off from target, even if mark point is precisely sitting on a ground vehicle. I tested this. In real life, JDAM has 5 meters radius where it will hit. After all it targets INS coordinate and coordinate is not point, but area. So do not engage tanks and maybe heavy armored vehicles with JDAM. For pin point accuracy use laser guided bombs and mavericks.
