OK, if my IFR GPS goes out (and my handheld goes out), I am down to
just my VOR/GS. No DME, no ADF, no GPS, no Marker Beacons. Am I legal
to fly an ILS? The only way I have of identifying the outer marker is
ATC radar, so certainly I would need radar coverage. So, lets say I
have radar coverage and its just a plain ILS, no DME or ADF
requirement? Legal? Safe?
