To be fair to Marty, I think light signalling is a little out of context.

In radio useage, NDBs and similar are disappearing so fast as to make you
think that they must cost money to maintain. I played with my RDF a couple
of weeks back, the first time in about five years, I could hear only one
beacon, and that was an aircraft NDB at that.

And NDBs have never required the users to be fluent with morse
anyway. They use morse so slowly that the morse is just printed
on the paperwork that lists the NDB details and anyone with a
clue can use that to make sure the correct NDB is being used.

Then presumably the pilots will qualify for a class F licence,

That may well come as a surprise to the users of aeronautical beacons.

numerous "numbers" stations.

ahh here!

now youre just being factual.

whats have facts got to do with morse code ?

Nothing whatsoever for those who know it all. Let them count the
number of amateur Morse stations on an active weekend band and compare
it with the number of SSB stations in the same band.

Perhaps they could count all the other modes as well and Morse would
still win.

Of course things have moved on and navies use PRINTER, STANAG-4285 and
LINK-11 and so on on HF, but some of them still use Morse extensively.
It's simple, cheap and enormously spectrum efficient as a standby
system.

Well I dunno, it might be spectrum efficient but the effort required to
learn it and the fact that only a tiny percentage of the population are
morse literate doesn't make it terribly useful in real terms.

I've learnt morse for my license but have never used it since. I don't know
anybody else at all that uses morse for communicating but I know lot's of
people that use email and mobile phones.

Clearly the administrations that no longer have

That is a remarkably simplistic statement. The sort of thing I'd expect a
3nd rate wannabee software engineer who last worked a long time ago on a
something he thought was safety critical.

Safety in any system is a matter of probability- reducing probability of an
incident to an acceptable level. That level is set by a range of factors-
cost and the state of technology being two of them.

Were safety "numero uno" then cost would not be in that equation.

Mr Reay.

I suggest that you go to any Chief Executive of any airline
and ask him/her whereabouts they put safety.

I suggest you go to any C.A.A around the world and ask them
where safety is in the pecking-order of subjects...

Would you like a list of KNOWN defects in aircraft that impact safety. If
you know were to look you will find it.

Safety is about risk and reducing risk costs money. Often, the lower the
risk the more it costs to ameliorate.

As I said, you view is simplistic in the extreme.

Yes, this is the sort of claptrap that the ignorant spout with grim
regularity.

Take the case of airbags fitted to cars, that is, the ones located in
the centre of the steering wheel.

This is all very well, but the centre of the steering wheel is where
past generations of horn buttons used to be. When carrying out an
evasive manoeuvre, you always knew where the horn button was.

Now they are located on the steering-wheel spokes, you don't know
where they are when carrying out /any/ manoeuvre. The driver might be
safer due to the airbag, but is the /car/as/a/whole safer?

Still, zpk comes from a country where the roads are littered with
cowsh*t and potholes, so what else would one expect?

FYI: In the USA - it is legal to send CW on the "phone" bands -)

URL: http://www.arrl.org/FandES/field/regulations/allocate.html

Few do as a matter of courtesy. But it is heard occasionally -- mostly DXers
making a phone contact then switching to CW for confirmation on that mode.

My post was to indicate that CW on the Ham bands is not dead as the a poster
implied.

Not with that specific question of requiring all pilots to be morse fluent it aint.

And that's because there is no reduction in safety involved
with having the NDBs morse ident so slowly that everyone
can check the ident against what's printed on the paperwork.

In fact the better NDB receivers decode it
automatically and display the ident in text form.

Completely trivial technology.

Maybe not, but with the ITU saying that CW is no longer a necessity, it wont
be long before the new generation of hams decide its all too much
trouble....

Gee, wonder if that means that the ITU don't consider morse to be that
important anymore????
