Ah, that would explain it. Must have missed those patch notes. Does this change affect GPS weapon accuracy, or is my JSOW/CBU inaccuracy something else?

Been having difficulty with the INS alignment procedure and I can not for the life of me figure out what I’m doing wrong. I follow all of the startup procedures as per Chuck’s guide, but no matter what I do I can never get the full alignment quality to “6” as stated in the guide and on ED’s official INS alignmentvideo, I can only get to “10”. This is roughly the steps I do Get the engine and power up and running Turn on the row of avionic switches above the EDI/GPS knob, minus the last one on the row set MIDS to on, Link 16 to XMIT on the HSI page Set GPS switch to on set EDI/GPS knob to “NORM” verify both lat/long coordinates by hi lighting them with the UFC rocker switch and pressing enter within two minutes of setting to align. I have also tried manually entering the coordinates. Sit back, drink some tea, wait for the 8 minute alignment process to end Cry because the alignment number won’t go below 10 and I wasted 8 minutes of my life This is fine enough for most uses, but with the recent additions of better GPS weapons (JSOW and CBU-105), this alignment it is no longer sufficient as both these weapons miss their mark with this degraded alignment. Is there some secret step that I’m missing that isn’t part of the ED tutorial video?

I can’t access your track file at the moment, but I can think of two possible things that could help if you want to try. I’ve had an awful lot of issues with JDAMs in the past myself. 1.) Make sure to use the laser range function on the TPOD when you do TOO. It gives you a more accurate coordinate input for the JDAM to target, and have found this significantly increases likelihood of a direct hit. I have no idea if this is realistic IRL, but it works in game. 2.) If your JDAMs are significantly off (usually you will see them initially fly in a very wrong trajectory, then take extreme maneuvers trying to hit a target once their GPS guidance turns on halfway through), then you likely have the chronic alignment bug plaguing a few of us pilots that affects the DCS engine itself (not specific to any module). The fix for this is to load up any mission and hop into a harrier (or whatever plane you want to fly), wait for everything to be loaded and then quit to main menu. The first time you load a plane any time you start DCS world, often times the Air-to-Ground GPS system completely bugs out at some point during your flight and you need to quit the mission and start again. After a module has been loaded once, the bug goes away until you next start up DCS world again. This might explain why some of your flights didn’t have issues, either the GPS hadn’t bugged out yet or you already unknowingly did the fix. This also fixes the A/G gun CCIP piper inaccuracy for both this plane and the F/A-18C, and various GPS weapon issues in the F-16 and JF17 if you have those issues as well. Not everyone has this bug, but if you do it happens ~95% of the time you fly. It’s worthy of note that ever since ED adjusted JDAM parameters mid/late last year, JDAMs using just GPS are no longer accurate enough to score direct hits 100% of the time against vehicle sized targets. This is intentional as it represents the IRL accuracy of the weapon. So if you noticed being able to wreck entire tank battalions in the past and are just getting back and wondering why you keep *just* missing targets, that might be why. I suggest always using laser JDAMs over regular JDAMs, so that when you are against heavy armor that requires a direct hit to knock out you can use active laser guidance which is much more accurate.
