BC stands for backcourse and is used on published BC approaches. Can't get into the specifics right now (no time), but (say theres rwys 16 and 34) basically a backcourse for rwy 16 uses the rwy 34 localizer and instead of chasing the needle, you fly away from the needle.
Hopefully someone else can get into more detail....

Not all... in FS, if there is an ILS, then it usually covers two runways (16L and 34R for example). If there is an ILS or LOC that ONLY is listed for one runway, then you can use the BC for the opposite runway. In real-life, this is only allowed if the back course is FAA approved.
