So who is going to apply carding to EMS? The US government isn't a customer or contractor. USFS carding applies only to US government contracts.
I agree with your points. My only point is that the "carding model" appears to work for the fire industry. I have NEVER been questioned for turning down flights. The relationship I have with my crew is one of mutual respect. From what you say---you have a good working relationship. The "carding pilots" I have flown with have all been former fire pilots in the industry with vast experience. My last carding ride was conducted by someone with 30 years fire fighting experience who just got hired by the government as a check pilot last year.
I do not claim to know anything about EMS, but maybe the carding "model" would help. How about having some "senior EMS pilots" who are well respected in the industry being "appointed" as "carding pilots". I do not know how it would work--just thinking out loud is all.
