What we could really use is some type of pay scale that would take into consideration the position you would be flying. There are numerous types of helicopter operations so you would have to generalize but you would have a base pay (entry level), more for IFR and in particualar SPIFR, Spray work, long line and the list goes on.
In the EMS field, it would be reasonable to have a basic start pay, with additional dollars payed for x ammount of hours expereince in that field, additional ammount for instrument time and then a cost of living allowance depending on where you live. Cost of living is perhaps the most important. I am working in Ann Arbor Michigan making about 50k US. Sounds good until you factor in the cost of living. If you compare that 50k to say Saginaw, I would only need to make 35k.
A little rambling but I think you get the point.
