Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Daher Tbm 960

The Airbus H225 is a heavy twin‑engine helicopter aimed at offshore, SAR, and utility transport; it typically carries around 19 passengers and has a practical range on the order of roughly 400–500 nautical miles depending on configuration and reserves. The Beechcraft King Air 360ER is a twin‑turboprop business/utility airplane in the light/medium commuter class; it usually seats 6–9 in executive layouts (more in special mission), and its extended‑range capability is roughly about 1,500–1,800 nautical miles. The Bell 525 Relentless is a super‑medium twin helicopter positioned for offshore and corporate missions; it commonly seats about 16–20 and offers a range broadly in the ~500–600 nautical mile class. The Daher TBM 960 is a high‑performance single‑engine turboprop business airplane; it typically carries 4–6 passengers (up to 6–7 seats including pilot depending on layout) and has a range around ~1,400–1,700 nautical miles. Overall, the fixed‑wing turboprops (King Air 360ER and TBM 960) dominate range, while the helicopters (H225 and Bell 525) lead in passenger lift for vertical‑access missions.
