Well thats a good thing to know.Flibmeister said:Actually, no. If the supervisor investigating such a loss of separation finds that the controller clearly intended for you to be where you were, he couldn't care less about whether there's a "cleared..." on the tape-- heck, he probably wouldn't even notice it.
In my 25 year ATC career, almost all pilot violations that went to FSDO (or GADO, or ACDO) were extremely solid ones that also caused a loss of separation-- altitude busts, etc. It's a lot easier to just write up the controller than to convince a FSDO inspector to pursue a case against a pilot who was doing exactly what he was told to do-- particularly if the controller used improper phraseology to tell him!
That said, I agree that "affirmative", without a call sign, was insufficient and required further confirmation.
Call me paranoid, but I'm always worried about busting some kinda reg somewhere...thats probably why I like knowing what the controllers of the world are thinking too. Kinda lets you into the "other side" mindset. Always a good thing for comparison...
Thanks for the post and the info!
