I tend to be a bit sceptical of the immediate value of an aero’s course... however, if you have the cash to splash, I can thoroughly recommend an Emergency Manoeuvres Training (EMT) course -during the course of which, you’ll be exposed to many of the basic aero’s manoeuvres anyway. When I did mine (a couple decades ago now) it was with Phil Unicomb at the RNAC in Maitland in a Pitts S2. I think Phil has moved on from there now, possibly based in Cessnock now. Others here will know. If that geographic location is not suitable for you, other outfits in SYD & MLB were doing similar courses.
I genuinely can’t recommend that course enough. It’s my opinion that training should be a part of CPL syllabus. I guarantee you’ll get more value out of it than the dollar value and it will stand you in good stead throughout your career.
