I would go so far as to say this is a giant "boondoggle"
I wouldnt be holding my breath waiting for this proposed "reform" to happen
The probable outcome ( if any ) will be the status quo wrapped in a new blanket.
Anyone who thinks that they might get relief from a CASA non renewed medical on the grounds they have a valid drivers license is dreaming.
The medical hurdles for a drivers license are very low and in the case of coronary disease or the potential for coronary disease almost non existent, there is no accounting for BMI or mild symptomatic issues controlled by medication, there is no requirement to declare medication.
I am all for the rationalisation of the medical standards which are by any standard draconian and the CASA medical audits are severe with little concession to the expertise of independent medical specialists.
But anyone who is in the belief that they will be cut slack and given a new way to fly with chronic but mild medical history needs to take a dose of reality pills.
CASA just ain't going to let go, it would create a massive liabilty for them should it all turn to custard.
And in any event all reacreational pilots are potential criminals who don't care about risk minimisation.
