Every ILS has a monitor for localizer and glideslope, and if they
aren't functioning properly there will be a notam that the monitor is
out of service and the component is unmonitored. If you lose RAIM on
GPS you have no backup other than VHF equipment, assuming you aren't
trying to use GPS as sole source of nav.

At least GPS has RAIM and will let you know when it is not reccieving good

ILSs are setup either monitored in a full time tower, or they are
setup for the "monitor", a far field receiver to shut down the
component if it goes out of tolerance or has any other alarm. So
unmonitored should be rather rare. No different than a VOR..either FSS
monitors or it is automatic.

I think part of the perversity of this incident is that the installation was
officially 'unmonitored' at the time which I think means that no person is
available to monitor the monitor and therefore issue the NOTAM that
hopefully gets to you before you get to the approach. Then the fact that
this particular type of failure still transmits a carrier and therefore
didn't flag the glideslope indicator created the situation that this NZ
airliner encountered. Then the .05G pushover 'feature' of the FMS.
Fascinating.
I'm not up on the WAAS based technology but I think a WAAS-based appoach is
what you would compare this to - does RAIM apply to WAAS precision
approaches?
