I fly with a VOR/GS and an IFR GPS, that is it (well radio and xpdr
too). The missed apporach on an ILS is defined by an altitude, NOT the
middle marker. The IFR GPS does not have the middle marker, though it
usually has the outer marker as a waypoint. Legally I do not need it,
operationally I do not need it. But I do sometimes wish I had it, as I
don't get the aural warning at the middle marker while I am looking
for the runway. The middle marker is usually near the missed, even if
it not exactly at it. Bottom line, if you are going to put in a new
audio panel, I would spring for the marker beacons, otherwise no. (It
requires an antennae also, right). This assumes you have an IFR GPS,
of course. If not IFR GPS, you better get marker, although if you are
not planning an IFR GPS, you should change to include one. All you
really need is an IFR GPS and a NAV/COM. And i prefer seperate
instruments so they don't go belly up together.

How much is a marker beacon receiver really used in IFR flying? I'm
building a new panel and need to decide if I want to include one or
not.
Appreciate your input.
