However it would be good to know why this is

According to Michael Frantzeskakis PMDG, the higher pitched tone is the DME. However, there is a minor bug in where an ILS without DME also has the second tone. Mystery solved.

I wondered the same for a while, nice to have found a topic about that.

 

Yes, nowdays could be still necessary to hear the morse, depending on the " captain " needings/preferences. What appears into the PFD is nothing more than tiny numbers and in busy landing not all the times one can check them with a magnifier lens to see if that's right or not. 

 

Better have a sound confirmation, it is a passive way of double-checking a check list item.

 

In an easy and not busy landing maybe the morse code is not needed but in a busy environment it could help a lot I agree.

In addition to the numbers a three or four letter ILS identifier code appears which can be verified to the code on the Instrument Approach Chart.

Yes correct, I always double check such numbers and code. I think everyone does it.

 

Maybe in a real cockpit it's big enough but in my 1980*1080 and 27", FS set on wide those codes and numbers appear extremely little, above all bcoz I fly max zoomed out in the VC.

 

One of my concern is always to catch the right ILS, 2 times during troubled approaches I picked up the wrong one ( my fault, I know ) and I failed the G/S. If I had the morse I probably would have had an additional check. We have no F/O helping us you know ) ..and 4 eyes see definitely better than 2 busy ones  !!

 

You know, the vast majority of real incidents are based on a chain of bad events, missing the morse in busy landing may be one of those

Since I can't decode morse code all the beeps at the OM are just sound to me but it does tell me that I am out the OM.

Yes you are again right. Anyway, Put it like that, if you hear the beep you remind yourself to check the fmc frequency/runway and above all the pfd annunciation code.

 

If you don't hear the beep you may forget to check the pfd or if you don't hear the sound more or less when expected you may have a misconfiguration somewhere and the lack of the sound may act like a " warning ".

 

All this must be seen as an optional step agree but the absence of an F/O is always a bad thing imo, above all when busy.

 

PMDG should implement an F/O, woman F/O possibly

Is it necessary these days? The ILS ident is displayed on the PFD anyway.

 

The way it was explained to me during my instrument rating (in a G1000 C172) was the displayed identifier does count as properly IDing the navaid.  You still could listen to the audio to supplement the display, but it's not a requirement unless the ID doesn't show up on the PFD for whatever reason.

 

Hope this helps,
