Airbus Helicopters H225 vs Leonardo Aw189 vs Pilatus Pc 24 vs Robinson R66

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters designed for offshore transport, SAR, and utility work, while the Robinson R66 is a light, single‑engine helicopter aimed at lower-cost private, training, and light commercial missions. The Pilatus PC‑24 is a twin‑engine business jet, not a helicopter, optimized for fast point‑to‑point travel and short/rough-field capability, so it sits in a different category focused on fixed‑wing speed and efficiency. In range, the PC‑24 generally offers the longest legs, commonly around 2,000 nautical miles class depending on payload and reserves. The H225 and AW189 provide mid-to-long helicopter range, typically in the several-hundred‑nautical‑mile class, with the H225 often configured for longer offshore sectors than smaller rotorcraft. The R66 has the shortest range, typically a few hundred nautical miles or less depending on fuel and load. For passenger capacity, the H225 is usually the highest among these (often configured around the high‑teens), the AW189 slightly lower (commonly mid‑teens), the PC‑24 typically carries up to about 8–10 passengers in executive layouts, and the R66 seats up to 4 passengers plus a pilot.
