Don't follow your line of argument, Andy. Who are these others you refer to?
Are they your passengers, your family, your fellow aviators, your neighbours or the guy in the house with his wife and kids living in the circuit area of your favourite airfield? Are they, perhaps, just someone somewhere who might be impacted physically or financially if you impact the same ground he is standing on?
People who drive motor vehicles pay for the regulation of their activities through licence fees (I just paid for another 10 years and hope to live long enough to get value from it); annual registration fees including third party insurance (about $650); road tax if you drive big ones; and massive on-the-spot fines for any infraction. Makes what I pay to RA seem a little insignificant by comparison.
RA has to be financially secure, and it has to do all the things the Regulator says it must. I can fly RA for less than one-third the cost of driving my car and that seems a pretty fair deal to me.
And, in case you aRe wondering, I also own and fly a GA aircraft.
