It is interesting that Russian Helicopters are equipped to fly in icing conditions, carry a big payload and have surplus power but are lacking in system redundancy.
Western countries have (mainly) helicopters that can't fly in ice and have limited power but have system redundancy.
To bad we can’t mix the best of both philosophies.
My wish list:
1:ALL IFR Helicopters should all be equipped with de-ice/anti ice capability.
2: Better range and efficiency.
3: Seeing as we are “thinking outside the box” a nuclear propulsion system; it is being worked on for drones.
