what is "LOFT modes, ARM, JPF, and other JDAM and JSOW remaining functions"?

Example in Harrier a LOFT mode is bombs delivery by system providing you the increased range to drop bombs by guiding you to distance and how to pull a constant 4g upwards to loft the bombs at the target. It is not same thing as AUTO mode that is not suitable for lofting, but it is the sub-mode of the AUTO delivery.

 

The idea of it is that you have better accuracy for release timing and maximum "standoff" distance to avoid local air defenses.

The good thing is with precision weapons, there’s a lot more versatility than just using the jet to lob bombs. The bombs themselves are programmed to know how to fly a better profile to maximize range/effects. Same for things like the PWIII series weapons if ED models the different guidance modes available.  They can actually pitch themselves into an arc to save you doing things with the jet to get the same results.

JPF stands for Joint Programmable Fuse.

With serial comms. the arming and delay could be changed from the cockpit.

One way or another, the ARM and DELAY have to be specified in STORES format, even when not able to be change them...  I think.

Loft mode will provide a dotted arc on the HSI that is linked to the 15 / 30 / 45 options you select when selecting Auto Loft mode. Obviously the arc will present the optimum position at which to pitch up, at one of those angles, at 4g to provide maximum loft to the JDAM. 
There’s some debate whether it actually improves range in all scenarios, since the JDAM itself has an autopilot that decides how to fly, unlike a purely ballistic dumb bomb. 
 

We should also get Launch Points, hopefully, which are another thing. JPF has sort of been confirmed as coming later, to be used with many aircraft.
