I have been flying for some 34 years now.
The first 10 involved lots of learning - PPL, CPL, MECIR, tailwheel endorsement, aerobatic rating, instructors rating, aircraft endorsements etc.
For the next 10 I believe I operated at a very high level of professionalism in both Oz and NZ. Knew pretty much all I needed to know about flight planning requirements, getting the weather and notams, radio calls, readbacks etc - all of that stuff.
IT ALL STAYED PRETTY MUCH THE SAME!
But for the last 10 years or so - I don't really have a clue. I read all the stuff that is sent to me. I pay attention to the calls etc that others are giving. I note what controllers ask of me. Every 12 months I get a bit of a refresher when I front my IR renewal - I figure the ATO is up to date with the latest and greatest.
BUT IT ALL KEEPS CHANGING! Read this back - no, you don't have to read that back any more - airspace is changing - not it's not, we've dropped that idea - this is how you do a circuit entry - now we want you to make these radio calls in the circuit - etc etc etc etc etc etc etc etc etc
I haven't pranged anything - I haven't run into anyone - and I haven't even managed to scare myself, but
I REALLY DON"T HAVE A F*CKING CLUE ANYMORE.
I say
"STOP F*CKING CHANGING STUFF EVERY 5 MINUTES - AND LET ME CATCH UP AGAIN!"
FTDK
Ahh - it feels good to have that off my chest!
