Wiz ... thanks mate, but I wooden dream of taking a chart that you might end up needing! Never know how far off track ya might find yerself!
I'll throw a couple of them thru me scanner tho!
Trash 'n' Navs ... I can't speak for AsA because I honestly don't know how they deal with Jeppesen. All I can tell you is from my own experience is that they liaise with me on a fairly regular basis. I'm not aware of any residual errors in their charts, because I don't check them. But they DO check details in our charts with me, whenever they feel that something is amiss.
Most of the time, it turns out to be an AIS production error that didn't get picked up before publication. I give them the correct information by e-mail and follow it up with a Notam, but the system here isn't geared to rapid issue of corrected charts. Thus I think it's fair to say that Jepps have the up-to-date info on their chart before we have it on ours.
As far as I'm aware, Jepps do not independently validate any chart from any aviation authority. They do, however, offer a procedure design service to anyone who wants it. You'd have to check with them for details of that service - unless of course we have someone from Jepps lurking here who can provide details.
From my dealings with them, they are very professional and very easy to get along with. If it was up to me, I'd be using them as our AIS but, sadly, it isn't up to me.
