Yet more GPS substitution questions

OK, if my IFR GPS goes out (and my handheld goes out), I am down to

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?


Sure.

You're becoming to0 dependent on your GPS :-)

There are any number of charted approaches such as you describe:

KPVC ILS RWY 7 has no marker beacons.
KPWM ILS RWY 29 has a MM, but there's no penalty for it being OTS.



Ron (EPM) (N5843Q, Mooney M20E) (CP, ASEL, ASES, IA)

Declare emergency, fly said approach.

The FAF is often fixed by VOR radials from other VORs, and you can
certainly use these. If you're vectored to the localizer, then the FAF
is glideslope intercept. The only necessity for the outer marker is
really to insure that you're on the main glideslope, not a false lobe,
and if you're vectored to final and intercept the GS from below, this
isn't a problem.

If?

Vectoring doesn't change the definition of the FAF.

OK, same scenario. All I have is one VOR/GS, GPS is out of service, BUT
now, NO RADAR service!! Can I fly the ILS legally? Safely?

I think you need an engine too :-)

Depends on the approach, and how the fixes are determined.
