If the aircraft are operated by a state department, then yes they are allowed to go outside of any rulings. But if the aircraft go to a private operator, they will ultimately be responsible for whoever they carry on board of their aircraft and therefore insurances will become a problem which will certainly have significant operating cost effects, assuming they will manage to get the insurance.
CHC warned me recently that my IR rating would not be accepted because I would have it done on a R44 IR training platform and it would go against the book. I guess it has nothing to do with the training itself. Flying IR on a R44 must be much more complicated than in an aircraft with AP and stabilizing gadgets of all sorts. It must be insurance related.
What can we expect from insurance companies regarding the transportation of medical patients on an aircraft that is not allowed to?
