:huh:....Marines don't fly A-10s :doh:
I can't find anything specific in the 2-1-1 but in another real world training document (and I can't share with anyone or ED) part of the ILS approach verbage states that you must dial in the localizer course using the HSI Course set know and select the ILS button the NMSP.
I take this to mean it is modeled correctly in DCS A-10C.
A-10C LIDS Check.
L(ocalizer station); select ILS on NMSP and ensure correct frequency on ILS control panel, tune, identify, and monitor
I(inbound course); Set course using HSI course knob
D(ME); set for localizer
S(low); to final approach speed
