Humble VFR single engine aircraft, including homebuilts, are targeted.
Woe betide any unfortunate pilot caught using any navigation data or charts that are out of date.
Do us a favour mate and put away your violin...
What "humble VFR single engine aircraft" nonsense !
You are sharing that airspace with other users as well as overflying an ever changing landscape.
I don't care how "humble" the bugsquashing brigade think their spamcans are .... there is no option in having up to date navigational data ... its a MUST. If you can't afford to keep your navs up to date, you can't afford to fly.
PICs failing to have up to date navigational data are putting others at risk as well as themselves.
Sounds like CASA is doing a great job of saving Australia from those who think otherwise !
