Airbus Helicopters H225 vs Cessna 208b Grand Caravan Ex vs Piper M600 Sls vs Robinson R66

The Airbus H225 is a heavy, twin‑engine helicopter in the super‑medium category, optimized for offshore and SAR missions. It typically offers the highest passenger capacity of the group (often around 16–19 seats) with a range on the order of roughly 450–550 nautical miles, depending on configuration and reserves. The Robinson R66 is a light, single‑engine helicopter, far smaller and simpler, usually carrying 4–5 people including the pilot, with a typical range around 300–350 nautical miles. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility airplane, valued for rugged short‑field operations and cargo/passenger flexibility. It commonly seats 9–14 passengers (often 9 in commuter service) and has a typical range around 800–1,000 nautical miles. The Piper M600 SLS is a single‑engine pressurized turboprop personal/business aircraft, generally seating up to 6, with a range typically around 1,000–1,400 nautical miles, making it the longest‑leg option here while carrying fewer passengers than the Caravan and far fewer than the H225.
