Airbus Helicopters H225 vs Piper M600 Sls vs Robinson R66 vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are heavy, twin‑engine helicopters typically used for offshore energy, search and rescue, and government transport. Both emphasize redundancy and payload, carrying roughly 16–19 passengers in common layouts. In range, the S-92 is generally around the mid‑400 nautical mile class, while the H225 is often quoted a bit higher, roughly in the 450–600 nautical mile class depending on configuration and reserves. The Robinson R66 is a light, single‑engine turbine helicopter aimed at utility and private missions. It typically seats 4 passengers plus the pilot (about 5 total) and has a much shorter range, commonly around 300 nautical miles. The Piper M600 SLS is not a helicopter at all but a single‑engine turboprop airplane designed for personal and business travel. It seats up to 5 passengers plus a pilot (up to 6 total) and offers substantially longer range than the helicopters here, roughly about 1,200–1,500 nautical miles depending on cruise and reserves.
