Well…it seems like I made a mistake.
The auto acmi operattion does work exactly like the manual operation.
There is though some kind a problem with ordnance recording which is lacking in online mp…eg some players’ employed ordnance don’t show on the tape…but that’s not for this thread.
1. In the CRM modes, yes it’s horizon based as much as the gimbals allow. In ACM modes (with the exception of slew I think) it’s airframe reference.
2. It’s just the scope position unless you bug it.
3. Nautical miles. Speeds will be either an KTAS or estimated KCAS.
Bang on correct with the addition that Ground speed is also used.
Slew will need some “love”
