Flight crews are warned that use of the Localiser outside these coverage areas can lead to false course and reverse sense indications being received. Such use should not be attempted.
Quite right - flight crews should never attempt such a thing.
However, ATC may exceed navaid limitations under several conditions, among them if radar monitoring is provided:
4-1-2. EXCEPTIONS
Altitude and distance limitations need not be applied when any of the following conditions are met:
a. Routing is initiated by ATC or requested by the pilot and the following is provided:
1. Radar monitoring.
2. As necessary, course guidance unless the aircraft is /E, /F, /G, or /R equipped.
NOTE-
1. Para 5-5-1, Application, requires radar separation be provided to RNAV aircraft on random (impromptu) routes at FL 450 and below.
2. When a clearance is issued beyond the altitude and/or distance limitations of a NAVAID, in addition to being responsible for maintaining separation from other aircraft and airspace, the controller is responsible for providing aircraft with information and advice related to significant deviations from the expected flight path.
