Road trauma is not just fatalities. It includes injuries and property damage.
Are you sure that all Angel Flight pilots are 'just' private pilots? Really sure? Do the ATPLs and CPLs become irresponsible when free of the shackles of a CPs scrutiny?
If there is a problem, it is not caused by Angel Flight. It's caused by human factors issues that have been around forever.
If the rules for day VFR Angel Flights should be changed, the rules for all day VFR private operations should be changed.
But hang on a second, if the current rules were complied with, there wouldn't be a problem, would there?
The problem isn't the rules. We're drowning in rules. If only all of that regulatory reform program money had been spent on instrument ratings and education instead...
My prediction: There will be no change to the regulatory requirements imposed on community services flights. Aside from all of the difficulties of defining what they are and are not - thus turning a dog's breakfast classification of operations regime into a bigger dog's breakfast - there is formidable political support for AF.
