Airbus Helicopters H225 vs Pilatus Pc 24 vs Robinson R66 vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are heavy, twin‑engine helicopters designed for offshore transport, search and rescue, and other all‑weather utility missions. Both typically carry around 18–19 passengers in a transport layout and offer long helicopter ranges on the order of roughly 500–600 nautical miles depending on payload, reserves, and configuration, with the S‑92 generally in the same class and the H225 often quoted slightly higher in maximum-ferry conditions. The Robinson R66 is a light, single‑engine helicopter aimed at private, training, and light utility roles. It carries up to five people including the pilot and has a much shorter range, commonly around 300 nautical miles, varying with fuel options and operating profile. The Pilatus PC‑24 is the outlier because it is a twin‑engine business jet, not a helicopter. It is built for fast point‑to‑point travel and can operate from shorter or less‑prepared runways compared with many jets. It typically seats about 6–10 passengers and offers far greater range than the helicopters, roughly 1,800–2,000 nautical miles depending on model and load.
