Paddopat. You misunderstand me. I have the greatest regard for our AOPA - certainly was not knocking their efforts to fix up Avalon on behalf of GA operators in the Melbourne area. But AOPA cannot do this without indications from the affected operators that they want it fixed. And if Avalon don't reply to correspondence from AOPA then that's the end of the story.
It is easier for operators to tack on the extra Avalon bucks at the end of the students account rather than engage in legal proceedings which will only fill the pockets of the lawyers.
