Airbus Helicopters H225 vs Bell 525 Relentless vs Daher Tbm 960 vs Sikorsky S 92

The Airbus H225 and Sikorsky S‑92 are heavy, twin‑engine helicopters aimed at offshore transport and utility work. Both typically carry around 19 passengers in an airline-style configuration (with layouts varying by operator) and offer medium-range mission capability on the order of a few hundred nautical miles, often roughly 500–600 nm depending on fuel, payload, and reserves. The Bell 525 Relentless is a newer large, twin‑engine helicopter positioned between medium and heavy classes for offshore and executive roles. It is generally configured for up to about 16–20 passengers and is marketed with longer range than many peers, commonly cited around the mid‑600 nm class, again highly dependent on mission profile. The Daher TBM 960 is not a helicopter but a single‑engine turboprop fixed‑wing aircraft intended for fast personal and business travel. It typically seats 4–6 passengers and delivers much longer range than the rotorcraft here, commonly around 1,000+ nm, reflecting fixed‑wing efficiency and cruise speed.
