Glide slope warnings should never go off when you are 10 miles out and tune in the ILS! NEVER! When being vectored to the LOC , the constant warning is useless. You are always vectored to a point outside OM at an altitude below the GS but above the MVA. This way you are in a position to intercept while in a stable flight configuration. Once you intercept the GS or inside the final approach fix the warning should alert you of any deviations both above and below the GS. At that point, the pilot is concentrating on flying the AC and looking for the lights.
