Is there any circumstance when either (1) ADF, (2) DME, or (3) IFR-certified GPS, cannot fully replace a marker beacon receiver?
I like having the backup indicator I'm where I'm supposed to be but beyond the first couple beeps, it becomes a distraction. I'd prefer an indicator that does only beep twice or three times then terminates while the light may continue flashing as long as I'm over the marker beacon. I'd rather not take my hand from the yoke and throttle unnecessarily to turn it off.When you just absolutely, positively have to have a light flashing and a beeper beeping.

Doesn't bother me...it freaks out my wife when we happen to fly across a beacon somewhere when we're not IFR though.
You should switch to a Commander then, and be soothed by the sound of a ringing bell when your gear is not down...Gear warning horn freaks mine out when it goes off with low MP. Marker beacons had not bothered her.

They never bother me, I've got a great ability to ignore things. Really helpful in relationships . Personally I like having a marker beacon.
No need to replace with anything as MBs are no longer required for any (cat I) approach AFaIK. Once upon a time there were raised mins when the OM or MM was OTS, but not any more.
This is what I suspected but, remarkably, had no idea of. I actually think that my plane has no MB receiver anyway, and that the display at the top of the 6-pack is a repeater from a no-longer-installed Collins MB receiver.
So, out it comes and a GPS annunciator will go in its place. Ba da bing.

Curiosity rules- what all is involved in getting Cat II certified? What was the process, and was it at all difficult for you to do, bureaucratically?
