Which is why I suggested the CAA NPPL standard (GP certified, commercial drivers license)
I don't have any. I'm going to give you a hypothetical, though:
- two weeks after heart attack, with reduced contractility (pumping strength of the heart), not enough to cause problems at sea level (or even be detected)
- the hypoxia at 10000ft may trigger a combination of cerebral hypoxia, myocardial hypoxia, or myocardial irritability
- poor decision making, and or brief periods of blackouts, may ensue
Such a person does not pass the unconditional drivers license requirements. RAA, however, has a softer medical standard than driving! You don't need an unconditional license to be an RAA pilot. There is no requirement that you fly within the restrictions on driving that you have. So someone who is restricted to driving on local roads only, is allowed to fly around Australia.
Pipistrel state, without producing the data, that their motor-glider registered aircraft have higher crash rates than the same aircraft flown under powered airplane registration, and suggest that the laxer medical standards are the cause of this.
