VOR - obsolete soon ....???
Hi y'all,
have heard various stories about VOR becoming obsolete in the near future. Is this true ? If so when? and will ILS be the only NAV used ?
Please forgive my lack of knowledge on this subject...

ILS is a nav aid used for landing. VOR can be used for an approach, however they are also used for other navigating purposes (you may find them at either end of an airway) therefore it is impossible that ILS equipment could replace all VOR beacons. NDB's are another form of navigation beacon used.

Howdy Kiwidan,
Well, can't speak for the rest of the world, but in the USA, VOR's will be around for a long time, as it has been realized by the FAA that to close 'em down too soon might not be a good idea.
The Instrument Landing System was actually in use before VOR's and likewise will be available for a long time as it provides specific guideance to selected runways for, if the aircraft is so equipped, automatic landings.

Kiwidan,
Don't think GPS will be phased out anytime soon, in fact the FAA has just implemented WAAS, so that lower GPS approach minima will be available. In addition RNP procedures will/are now being used for arrivals/departures (enroute as well) to increase airspace utilization. GPS is very necessary for all this, so don't think it will just go away.

I gotta get a life. See, I actually find the exchange itself interestinng (and Dan, this is not a poke at your question, nor does it take issue with 411A's answer... It's a communications thing) Kiwidan asked:
Correcting the post after some replies to ask:
To which 411A responded:
What was "GPS" supposed to replace in the original post? Was this an enroute question or an approach question? Did the question become:
...have heard various stories about GPS becoming obsolete in the near future. Is this true ? If so when? and will ILS be the only NAV used ? or
...have heard various stories about VOR becoming obsolete in the near future. Is this true ? If so when? and will GPS be the only NAV used ? (Don't think we were supposed to replace "NAV" with "GPS" though...)
God help me, I cannot say why this is so blasted interesting to me. Apparently I'm not drinking enough.

Ah yes, I see it all now. I think this is what was meant...
That being the case, yes there's a chance that VORs and NDBs and even DMEs will be phased out in time, to be replaced by GPS for enroute and non-precision approach. The speed with which this happens might make yer average snail look like a record breaker so don't hold your breath. My information is that the FAA has plans to rationalise the number of VORs that they will continue to maintain into the forseeable future, but it isn't an especially aggressive rationalisation. The last I heard, they were talking about retaining some 900 VORs!
There is certainly going to be scope for regulators all over the world to go deeply into GPS with the advent of receivers meeting TSO 145A or 146A specifications. It is certainly being looked at very seriously in the poorer countries that have difficulty in keeping conventional navaids serviceable. However, I doubt that you'll see significant changes in less than 5-10 years.

I can see it now: Commercial Pilot Written Exam Question Pool...

What does the future hold for navigation aids?
(a) I have heard various stories about GPS becoming obsolete in the near future. Is this true ? If so when? and will ILS be the only NAV used ?
(b) I have heard various stories about VOR becoming obsolete in the near future. Is this true ? If so when? and will GPS be the only NAV used ?
(c) I need to get to cocktail hour a little earlier as I'm not drinking enough.

Bloody hell....look what I have started....haha !
I would also like to ask if GPS equipment will become 'compulsory' in ALL aircraft soon..?
Just another thing I heard....
Any takers...

Compulsory - possibly given time.
Given that TCAS is mandatory now and things seem to be moving towards the introduction of ADS-B ( GPS a prerequisite ) I would imagine its on its way in the near future

USA ground navaid wind down - approx 2010 to 2020.
Germany ground navaid wind down - 2003 to 2010.
Australian navaid wind down - 2005/6 to 2012.
The writing's on the wall..........

Oi ORAC, ya missed the AIP Supplement just issued by Papua New Guinea. The timelines are similar to those notified by Oz. 
Probably only of academic interest tho!

Not so, ferrydude, WAAS is GPS only.
Now on the other hand, LAAS is another kettle of fish, and does require a locally based navaid.
It is 'hoped' that LAAS will provide (eventually) CATIII capability for landing minima.
Don't hold your breath.

Many 3rd World VORs Inop
In Brasil, between Manaus (MAO) and Campinas (CPN) there isn't one VOR that's working. I imagine that there's no incentive to keep them operational since everybody has GPS or INS.
