Bell 525 Relentless vs Enstrom 480b vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Piper M600 Sls

The Bell 525 Relentless and MD Helicopters 902 Explorer are twin‑engine turbine helicopters, while the Enstrom 480B is a single‑engine turbine helicopter and the Piper M600 SLS is a single‑engine turboprop fixed‑wing airplane. In range, the Bell 525 is generally the longest‑legged of the helicopters listed, designed for longer offshore and corporate missions; the MD 902 typically offers moderate helicopter range suited to EMS, utility, and corporate roles; and the Enstrom 480B is usually shorter‑range than the larger twins. The Piper M600 SLS, as a pressurized fixed‑wing aircraft, typically provides substantially longer range than these helicopters and cruises much faster, making it better for city‑to‑city travel where runway access is acceptable. For passenger capacity, the Bell 525 is the largest, commonly configured for a higher number of passengers in executive or transport layouts; the MD 902 seats fewer than the 525 but more than many light helicopters; the Enstrom 480B is generally limited to a small cabin group (often around five seats including the pilot); and the Piper M600 SLS is typically a six‑seat aircraft (including the pilot).
