Nah, you all should panic. There isn’t any real reason to, I just get a kick out of it.
If you pay attention, that stores page is functionally a combination of three pages that exist on the A-10C: DSMS, Profile and Inventory. For Mk-8x, LGBs and Rockets, that is as complex as it gets.
Most of this should have been previously set up on the ground. Practically all you need to do is call up A/G mode (the A/G button on the left eye-lid). Bring up the STORES page, hit PROG until you see the program you want. Find the target and then hold down the pickle button.
I can’t repeat this enough: if you can handle an A-10C, you shouldn’t have any problems with this jet. The F/A-18C has a much more streamlined and ergonomic interface.
