Robinson R66 vs Sikorsky S 92

The Robinson R66 is a light, single‑engine turbine helicopter aimed at private owners, training, patrol, and other utility missions where low operating cost and simplicity matter. The Sikorsky S‑92 is a large, twin‑engine medium/heavy helicopter built for demanding commercial and government work such as offshore oil support, search and rescue, and VIP or airline‑style transport, emphasizing redundancy, payload, and all‑weather capability. In range, the R66 is suited to shorter regional trips, typically offering roughly a few hundred nautical miles of practical reach depending on fuel load, reserves, and conditions, while the S‑92 is designed to carry people and equipment much farther, often in the mid‑hundreds of nautical miles and commonly used on long overwater sectors. Passenger capacity differs dramatically: the R66 normally carries a pilot plus up to four passengers (about five seats total), whereas the S‑92 commonly seats around 19 passengers in a standard transport configuration (with variants and interiors that can change the exact number).
