Morse Code
Are PPL students supposed to learn it? I mean how useful a skill is it to have?
During my time away from the Trevor Thom manuals I have decided to learn morse code, if only for a break from the reading. It's not as hard as initially feared - I think I have most of the letters learned by their sound. I bought a CD off of the Internet.
My understanding is that it is used for identifying navaids. I have read on PPRUNE that the big boys don't really need to identify morse because their FMC's do it for them and that they don't even have to learn it for their JAA ATPL.

Even CPL don't need to learn it, if you check your maps, next to the navaid's frequency they have ther morse code identifier. Its just dots and dash which you can clearly hear when you have the navaid tuned.

True; but it isn't terribly difficult to learn, to the standard needed to be able to read a navaid ident in morse. After all, they only transmit at about on letter per second, don't they? In my opinion, it isn't hugely more difficult to learn to that standard than it is to lean, say, the phonetic alphabet. Just my two-penn'th, of course.

I have tried to learn it loads of times, I just don't seem to have the ear for it.

At my Morse exam - General Belgrano, Gatwick – the invigilator commented upon the amount of spare pencils I had on my desk prior to the test. (We were advised to have spares available because if you break a point – you simply don’t have time to search for another)
“One for every time I’ve taken the test, mate” - was my reply.
Broke the ice amongst some nervous and stressed out candidates.
Learning Morse code has been useful: once when making a UK IFR approach after the runway in use was reversed - the ILS was mistakenly not adjusted. Identing saved me the embarrassment the A/C in front of me must have experienced making sort of back beam approach.

It's quite easy to learn the Morse letters in a couple of evenings using one of the computer based tutors. Or get a fancy Garmin, and let it do the identing for you.
Not really needed for PPL, but why not have a go anyway and surprise your instructor.
Although there is no more "Signals" test for CPL, I think that it is still a required part of the training syllabus.
You probably only need to remember about 2 or 3 local beacons on the PPL course.

In most cases you are using Morse to confirm identification. By that I mean you already have the ident on your chart and are listening to confirm the dots and dashes meet your expectations.
It becomes trickier if you hear a Morse signal you cannot recognise because you now have to work backwards to find the letters and pinpoint the navaid. I have a little diagram clipped to my kneeboard which helps.

In what circumstances would one need to identify an unknown navaid from a morse signature?
All that the morse ID does is confirm one has the right frequency tuned and the navaid is not officially offline. It does no more and no less. Specifically (despite widespread suggestions to the contrary) it tells you exactly nothing about any failure in your receiving equipment. I've flown with duff VOR and DME equipment which sounded out the correct ident, but wasn't working; the best example was a certain G-xxxx PA28 Archer, used for IMC training
in which the DME would read 5.5 when the distance was 3.7, etc.

Yes but then you have the wrong navaid. The approach plate (or whatever) is the reference which one must work from. Why go rummaging around for a navaid which matches the ident? If one tunes in a navaid and heard some other ident then one needs to report it to ATC; I can't see what useful thing one could possibly do with such a combination.

In these days of GPS, does anyone really use radio navaids any more (other than the fact that the CAA won't come into the 21st century). Might as well use Roman semaphore towers as a VOR or NDB these days. And signal squares?

Yes, in the IFR enroute context, navaids are handy as a backup to GPS BRNAV (BRNAV, which means GPS, is mandatory for enroute IFR in Europe). Instrument approaches are however still based on navaids: ILS, VOR/DME, NDB/DME, etc.
There are some GPS approaches in Europe but only a few, and all of them AFAIK are at airports that have conventional-navaid approaches to the same runways. Such approaches sometimes use an NDB as a part of the missed approach, which defeats the point somewhat...
One can fly enroute, VFR or IFR, entirely on GPS but it's wise to always have two methods of navigation a) in case one packs up and b) it tends to pick up gross errors like flying 080 instead of 180 (easy to do with a VOR but nearly impossible with a GPS).
That said, if using VORs and NDBs as a backup for a GPS enroute, one tends to not bother identing them.
The FAA does not require identing navaids at any stage up to and including the IR.
Personally, I ident all navaids used in an instrument approach. It helps to pick up mis-tuned frequencies.

Have you read this? It might be partly relevant?
My suggestion is that you learn the dang thing. It will take you one, two days at most (if not, up your intake of fish
). Train your ear to recognise the SOUND not the number of dots n dashes ("oh how many dots n dashes was that, hang on which one was that, Y or Q ... F or L.. d'oh!!!"). It'll become second nature as you ident a navaid and you'll instantly recognise it as right or wrong and you'll have LOTS of spare capacity to deal with the rest of your tasks.

Agree that! Forget the little charts, and learn the music of the morse. I learned it back in the dark ages for my amateur radio licence, and it's been a great help when flying.
Yes, the examiner will "comment" if you don't look at the printed dots and dashes, but explaining that you read morse will avoid any problem. It's great when you mistune a VOR or press a wrong button, and recognise the different (unexpected) ident.
The FAA certainly wanted me to ident any navaid on my IR checkride - and to leave the ADF ident running the whole time I was using it, in case it went "off air" during the procedure or missed.

Thanks for the help and advise.
It's already taken me longer than 2 days to learn 20 letters. Did you mean 48 hours of study? I must have studied for much less than that so far. I have the hardest (longest) ones remaining to learn. Still - my mates at work are well impressed already.
I should nail it this weekend, along with book 5 - Radio navigation.
Cheers,
Alex

Fly to Majorca, Palma (LEPA) and ident the VOR there (JOA, 117.7). Chances are you'll still get the Toulouse beacon until you are halfway down the descent on a 757. The higher you fly, the more chance of getting the wrong ident and VOR. Same with ATIS. Get Brussels (?) trying to get Cardiff when descending over London. Also, over London and identing Cardiff ILS you'll get Gatwick ILS until passing Swindon.
