holdingagain, posting again: The medical isn't for YOUR benefit, it is a risk mitigation exercise to protect people on the ground and others in the air.
There is NOTHING to prevent you from having a medical every year to whatever extent you wish to pay for including blood tests, stress tests, colonoscopy and what ever else you wish to do.
This has exactly ZERO to do with the requirement for a formal aviation medical. This whole discussion paper is a result of medical reform for PRIVATE pilots in the UK and USA and AOPA Australia's push for the same here. The wide terms of reference of the CASA discussion paper are completely unnecessary. AOPA wasn't talking about Class 1 medicals for Commercial or ATPL nor for extending the RAMPC to recreational aviators in RAAus and GFA, just bringing the Class 2 medical requirement to that required to drive a private car in an Australian State. This experiment has already been run by GFA and RAAus and by private glider and balloon pilots in the USA and there are no adverse results.
