Has anyone else had a good look at the new Deniliquin VNC? Just having a quick peruse and I notice that the aerodrome info for Swan Hill (YSWH) has wrong information for both the CTAF and the NDB frequencies, and that for Corowa (YCOR) has a wrong NDB frequency. I haven't done a "fine-tooth comb" investigation, but this seems incredibly slack on the part of AirServices.
What happens in cases like this? Do they publish an erratum, or offer to exchange wrong versions?
Cheers, Rattly
Edit: and Warrnambool. And, Baswell, it was the OzRunways version I was looking at

It looks like the info bubble for Deniliquin has been copied and pasted at Swan Hill. Even the lat/long is the same. The NDB and lat/long has also been pasted at Corowa, but they thought the change the ctaf frequency......not looking good for the rest of the chart
For error reporting on vnc (and all published docs) please send an email to docs.amend@airservicesaustralia.com detailing the error....it will get followed up.
That VNC was circulated (not widely) as a draft for user comment I guess, well over six months ago. I saw one briefly, but couldn't get hold of one myself.
This begs the question to be asked... does one (in practice) use the CTAF listed on the VTC or in the ERSA....?
Personally, if it's for a landing, I'd use the ERSA but it I was overflying I might refer to the VTC, but on the other hand, one should be checking the ERSA for any special procedures, gliders etc.
Which also begs the question, why did CAA ramp check people at Temora last Easter for out of date WAC's. Things like towers, buildings and runway works are supposed to be covered by NOTAMS. Lots of things may change, but mountains don't move. One used to get WAC amendments, but now you have to buy the chart.
Asa are aware and are onto it. There's already a couple of notams in the YMMM series. I'd use the ersa entry when visiting those places. But keep a good lookout for people on the wrong freq!
In response to question by Messers Arouet, Aimpoint and Bentleg,
WACs will expire periodically, usually lasting about three years. New charts will be periodically required as although mountains don't move, people do tend to build structures, usually antennas, on the highest of those features in an area, necessitating people who fly planes needing to know about how low they can fly. Info about new ALAs and removed ALAs can also come in useful from time to time, especially if you have an impending mechanical issue, are running out of light/fuel/brains etc...
The following AIC lists the current edition of every WAC and the amendments you should be making by hand to each chart.
WAC's are released every 2 years, and each 2 years half of Australia is updated (ie a full refresh every 4 years). There actually isn't a full database of obstacles in Australia.
I did several low level navs this week and spotted many obstacles that aren't on the charts. Mostly mobile towers.
