Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Piper M600 Sls vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are both large, twin‑engine helicopters aimed at offshore, corporate, and utility missions, but the S‑92 sits in a heavier transport class with the highest typical passenger capacity (often around 18–19), while the 525 is usually configured for fewer passengers (commonly around 12–16) and emphasizes modern avionics and efficient long‑range cruise. The MD Helicopters (McDonnell Douglas) 902 Explorer is a lighter twin‑engine helicopter in a different category entirely, optimized for law enforcement, EMS, and light utility; it generally carries about 7–8 people and offers shorter range than the two larger twins. The Piper M600 SLS is not a helicopter but a single‑engine pressurized turboprop airplane, typically seating about 5–6. It generally delivers longer range and higher cruise efficiency than the helicopters listed, but it cannot provide vertical takeoff/landing or hovering capability, which are central advantages of the rotorcraft.
