Bell 525 Relentless vs Pilatus Pc 24 vs Robinson R66 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are large twin‑engine helicopters aimed at offshore, corporate, and utility missions. The 525 is a modern “super‑medium” category aircraft with long overwater legs and typically seats around 16–20 passengers depending on layout. The S‑92 is a heavier “heavy” category helicopter, commonly configured for high‑capacity offshore transport, often around 19 passengers, and it also offers long range, generally comparable or somewhat greater depending on tanks and payload. The Robinson R66 is a much smaller single‑engine light helicopter designed for short to moderate missions, training, and personal or light commercial use. It typically carries 4 passengers plus a pilot (about 5 seats total) and has far less range than the larger twins. The Pilatus PC‑24 is a twin‑engine business jet, not a helicopter, optimized for fast point‑to‑point travel with a longer range than the helicopters listed. It typically seats about 6–10 passengers in executive configurations, trading vertical lift for higher cruise speed and longer legs.
