We were all new once and I bet there are a few guys with a lot of 73 time who didn't know this 'technique' but aren't owning up to it.
I have 3000 hrs in the 73, I didn't know it, I don't actually care either, you can't know everything and I can wait an extra 10 mins for an ATIS.
I guess I think you should probably already have a good idea what the weather is doing at your dest anyway. But hey, you want the atis and know how to get it- knock yourself out...
My new favourite pprunner.
