Airbus Helicopters H225 vs Bell 525 Relentless vs Bombardier Global 7500 vs Piper M600 Sls

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters suited to offshore transport, SAR, and high‑utilization utility missions. The H225 typically offers longer real‑world endurance and a higher maximum seating density, commonly carrying around 16–19 passengers, with range roughly in the 450–500+ nautical mile class depending on fit and reserves. The Bell 525 is a newer‑generation super‑medium with modern avionics and fly‑by‑wire, generally configured around 12–16 passengers, with range commonly quoted around the mid‑500 nautical mile class. The Bombardier Global 7500 is an ultra‑long‑range business jet in a different category entirely, optimized for intercontinental travel at high speed and altitude. It can fly about 7,700 nautical miles and typically carries 8–19 passengers depending on cabin layout. The Piper M600 SLS is a single‑engine turboprop personal/light business aircraft, aimed at owner‑pilots. It typically seats 4–6 passengers and offers roughly 1,200–1,600 nautical miles of range depending on power settings and payload.
