Corrections to my last post:
1.         I my opinion S is far too close to A on a QWERTY keyboard.  For LHS, please read LHA.
2.         I said that when plotted, an NDB relative bearing from Tripoli would give a clearly worrying position line.  This would only be true if the Captain noticed the discrepancy in the compasses immediately it occurred.  If the aircraft had been steering the incorrect heading from shortly after take-off, but the pilot didn’t notice the discrepancy between the compasses for some time, the position line would have come out on track even though the aircraft was off track.  E.g.  Ignoring drift, course required 180(M), indicated course steered 180(M) actual course steered 210(M), actual track made good = 210(M).  Tripoli bears 180(Rel).  180(Rel) + 180(M) indicated course steered – 180 gives Plot 180(M).  The aircraft appears on track even though it isn’t.
