ILS Backcourse RNAV

When flying the reciprocal track the aircraft may receive the sidelobes from the ILSILS —Instrument Landing System localiser. It will not receive sidelobes from the glideslope (the sidelobes from the glideslope are responsible for the false glideslopes on the "correct" side.) Because it is a literal mirror image, the 90 and 150 lobes will be reversed and so the localiser will sense in the incorrect way.
