correct as is JDAM PP Mode does not work if elevation at 0

[fumap]

Hi,

I don't have a track but it's an easy bug to reproduce. When using JDAM in PP mode, if you set elevation of the target to zero it does not consider valid the target position/elevation and PP1-4 remains crossed in the MSN page. Tried multiple time on boats in an harbour (Raven One mission 10 as an example) but the only solution is to set 1 feet as elevation and then PP mode "unlocks".

Ok, I created a track file. Issue is true for any JDAM bomb, multiple or single rack.

Not sure this is a bug, I will need to check with the team. 
Adding all of the correct data for the JDAM maybe a requirement before you can unlock the other PP slots, but I will see what I can find.  

thanks

Thanks!

Makes sense for the other PP slots, the issue I wanted to raise up is that PP mode does not accept 0 as a valid elevation.

In the track you can see that if I set elevation to 1 foot everything works (PP not crossed). If I set elevation to 0 it shows as invalid.

I will recheck but when I was leaving elevation to zero I still had a valid release condition for the first PP slot.

I am marking this correct as is, I can not find any information that it is not correct. Entering a valid elevation for the weapon is required, if you find anything to suggest it should not feel free to PM me. 

thank you

So I saw something very similar, but with PP mode.

- Hot start from CVN-71

- Load with 8 JDAM (4x2 BRU-55)

- Enter 4 sets of Coordinates

- Select all 4 Stations

- DROP salvo when IN ZONE

- ALL JDAMS MISS by a fair amount.

Turn back in. Make no changes to coordinates or station selection.

- DROP salvo when in zone.

- All 4 Hit.

Reproducibly. First SALVO always seems to miss.  These happen to be SHIP targets because they are big. Set to 0 speed with no waypoints. 

Sorry you have to watch me enter coordinates forever at the beginning of the trk 

Tried with TOO, 4 drops, 4 hits. No problem with RADAR or RADAR+FLIR designation

Note, I also saw the other issue reported where an entry of Zero Elevation (or leaving the 0 elevation alone) results in the PP1 remaining crossed out. Doesn't seem to affect Release or targeting as the second salvo hits where it was aimed.

I do have a script running to respawn all 5 ships when the group is destroyed, but, since I only drop 4 JDAMS, and one is not enough to kill the big ships, there isn't a chance that they are respawning somewhere else, and if they were it would be AFTER the first drop, not before.

 

OOPS!!! I meant to attach this to the other THREAD about TOO JDAMS missing after Hot Start on SuperCarrier. THIS HAS NOTHING TO DO WITH THE 0 ELEVATION ISSUE, JUST SEEMS THAT THE FIRST PP SALVO AFTER TAKEOFF MISSES.

 

GRRRR... Just tried it again for the 4th or 5th time...(PPJDAM2.TRK) EVERY JDAM IN THE ORIGINAL SALVO hit dead on.  I did NOTHING different except wait a few more seconds after the initial IN ZONE cue.  In the PPJDAM.trk, the Second Salvo that hit, was launched JUST as the IN ZONE was reached and hit, so I don't know what is going on now.
