Airbus Helicopters H225 vs Bell 525 Relentless vs Daher Tbm 960 vs Robinson R66

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters aimed at offshore, SAR, and VIP transport. The H225 typically carries more people, often configured around 16–19 passengers, and is optimized for heavy-lift missions with a practical range in the roughly 450–600 nm class depending on fit. The Bell 525 is a newer-generation super‑medium with a similar mission set, usually seated around 12–16 passengers, with a comparable long range (often cited around the 500+ nm class) and modern avionics and fly‑by‑wire. The Robinson R66 sits in a much lighter category: a single‑engine turbine helicopter typically carrying 4 passengers plus a pilot, with a shorter range commonly around 300+ nm, suited to utility, training, and personal transport rather than offshore lift. The Daher TBM 960 is different in kind: a single‑engine turboprop airplane, not a helicopter, optimized for fast point‑to‑point travel. It carries typically 4–6 occupants and offers substantially longer range (about 1,000+ nm) at much higher cruise speeds than any of the helicopters listed.
