Which helicopter can operate with one engine?

Explanation:
In helicopter operations, whether you can fly on one engine depends on the aircraft’s certification and performance margins after an engine failure. The HH-60 Jayhawk is designed with one-engine-inoperative capability, meaning if one engine fails, it still has enough lift and handling to continue controlled flight to a safe landing. This capability is essential for long-range rescue missions and reliability in adverse conditions. The HH-65 Dolphin, being a smaller, lighter platform, does not have that same one-engine-out certification and performance margin. With one engine out, it cannot guarantee safe continued flight, so it is not considered capable of operating on a single engine. So, the helicopter that can operate with one engine is the HH-60 Jayhawk.
