The different regulatory consequences of the different sources of that $1 are astonishing. The different safety consequences are not obvious to me.
Well the different safety consequences are obvious to me... Thinking back to three twenty somethings flying in an overloaded Tri Pacer around Australia, sleeping under the wing. We had carefully budgeted for fuel but that didn't work out and there were various long distance calls to the Bank of Dad. The Dads kept us airborne.
So now what happens when the pilot realises that he may have to pay for her desired fuel load with a parental issued credit card or perhaps a corporate card or carnet and CASA is looking on, already suspicious of your groups bona fides? There are a whole swag of safety related operational decisions , starting with avoidance of "Hot Spots" that must be taken if pilots must contemplate the possibility that CASA will trawl through trip finsnce details.
In addition, how wide is CASA's definition of "reward"? Does it include sexual favors?
