Hey SASless....great arguement for the pro's and con's of multi-engine CAT A ' Performance One power and crew requirements as indicated in the JAR's. FAA could possibly regulate a little more stringently, and mandate basic Heli Ops requirements similar to the European and others when it comes to Air Ambulance or HEMS.........consider the makeup and profile of the cargo carried....entitled to the best levels of care.......which includes twin engined helicopters with two crew!!
