But then you get back to Ben’s point. Why not 5700kg? Why set an arbitrary limit at 3000kg? Even 5700kg is an arbitrary limit.
What does weight have to do with it? A PBY Catalina weighs about 12t normally. Ive flown one on a Class2 medical PPL. Whats the risk if I only have a Class5? Another of Bens points, you either have been taught to fly that particular aircraft competently or you havent. Your medical status has very little to do with it
Surely we’d get further if we could identify what risk we are trying to mitigate? Maybe we need to focus on types of operation rather than weight? This was also Bens point. CASA advertise themselves as a risk based regulator, yet they cannot articulate the risk they are mitigating against in the medical reform.
