Airbus Helicopters H225 vs Bell 525 Relentless vs Daher Tbm 960 vs Piper M600 Sls

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters aimed at offshore, SAR, and utility missions. Both typically offer a practical range on the order of roughly 500–700 nautical miles depending on payload and reserves, with cabin layouts commonly accommodating around 12–19 passengers (higher in dense seating). The H225 generally leans toward heavier-lift cabin volume and established offshore use, while the 525 targets similar missions with modern avionics and efficiency. The Daher TBM 960 and Piper M600 SLS are single‑engine turboprop airplanes optimized for fast, owner‑pilot travel. They trade vertical‑lift capability for longer legs and higher cruise efficiency: the TBM 960 typically reaches about 1,400–1,700 nautical miles with NBAA-style reserves, carrying up to 6 occupants (often 4–6 in comfort). The M600 SLS typically offers about 1,000–1,400 nautical miles depending on conditions and load, with seating for up to 6. In short, the helicopters prioritize access and cabin utility at moderate range, while the turboprops prioritize point‑to‑point speed and range with smaller passenger counts.
