Can someone please verify that the burst altitude of a CBU is in MSL and therefore the elevation at the target must be taken into account when setting the value in the SMS?

Thanks for your help in advance,

It's adjustable, so it all depends on the target.

Hi Purple, thanks for the quick answer but I know it is adjustable. Is what you adjust in MSL or AGL or does the FCR take this into account somehow.

In the SMS its the AGL you enter. But if you are asking this question then maybe there is something more fundamental that you don't understand.
If you can be more detailed with your question then I can explain more (about the non classified stuff..).

Simple answer: You enter AGL. More detailed answer depends on which CBU and which F-16 you're talking about. The burst altitude of the CBU is not necessarily in MSL.

Thanks guys.

Maybe I do have a misunderstanding. I understand that you must first know the elevation of the target and then add the CBU burst to that. i.e., target is at 2500ft (on a hill let's say) I want a burst of 2000ft AGL. So I set 4500ft in the BA setting under CTRL within the SMS. Is that correct?

No, you set it to 2000 ft.
This doesn't affect at all the elevation that the CBU will open. It's just for the bombing piper and cues to be accurate.

The elevation of the CBU is determined from the fuse that is used.

Thanks Fezt!
