Source measurement	—	The HH-65 Dolphin is used for homeland security patrols, cargo , drug interdiction , ice breaking , military readiness, pollution control , and search and rescue missions. The HH-65 is known for its Fenestron tail rotor and its autopilot capabilities, which can complete an unaided approach to the water and bring the aircraft into a stable 50 ft (15 m) hover, or automatically fly search patterns, an ability which allows the crew to engage in other tasks.^[source]Eurocopter MH-65 Dolphin · Development; only the objects and conditions stated in this passage The HH-65A's minimum equipment requirements exceeded anything previously packaged into a helicopter weighing less than 10,000 pounds (4,535 kg).
