We lost something when some airports took away the approach NDB which enabled a 'confidence check' on the correct localiser position. Now we have LNAV and MAP which are fine as long as they mean what they say! Too many people rely on the MAP display for SA.
Not quite sure how true that is ?? I always try and have an aid, either NDB or VOR, to confirm the LLZ, and most still have one or the other? Indeed, when "cleared to intercept the Loc" I ensure that the Loc is ident'd, the Loc indicator to the "expected side" and that the independant aid agrees with we are near the Loc. With a NOTAM re false captures, I don't believe the Loc should be armed until the Loc indicator is off the stops AND the "aid" confirms the correct radial etc.
Of course, I am seemingly fighting a one man battle and 99% of my colleagues just press the Loc button with 1 ms of being cleared to intercept with not a thought as to ident, indication, false captures, backup aid, terrain or monitoring the intercept as it occurs etc..
