Morning Bob,

Here is one: ILS 27 for KIPT in PA.
Have you come across some regulatory materials on this?

BTW speaking of regs something else non-related comes to mind: the ELT
(e.g. battery replacement) requirements for aircraft still equipped with
121.5 ELTs. I am not aware of any requirement changes, yet the frequency is
no longer monitored by sats. Is an aircraft considered airworthy, if the
121.5 ELT battery has not been replaced on time?

Good Evening Jose,

That is undoubtedly a controversial discussion.

My inclination is to eliminate the marker beacon receiver, though, just
like many other folks, I like the friendly tones of the marker beacons when
they are being flown over. It is comforting and familiar.

Up until a few years ago, the marker beacon was a required portion of the
ILS system. That is no longer the case. The marker beacon is NOT a
required portion of the ILS and the minima does not change if you are or
are not equipped with such a receiver.

To my knowledge, there is only one non precision approach in the USA that
has a step down fix based on crossing a marker. That is the circling
approach from the (LOC-D, KSEE) localizer approach at Gillespie Field, San
Diego, CA. The last time I checked, that marker was out of service awaiting
parts for a repair. If you are equipped with an IFR approved GPS and a
current datacard, you can check passing over the marker beacon utilizing
the GPS and use the minima associated with that marker.

I would save the space, power, weight, and cost by leaving the marker
beacon off the airplane.

Does anyone on the list know of any other approach where any lower minima
can be flown by having a marker beacon available?

Happy Skies

Resending with explanation

Morning Bob,

Here is one: ILS 27 for KIPT in PA. The lower OM minima applies if flown as
non-precision, supporting your point.
