Bell 525 Relentless vs Embraer Legacy 650 E vs Enstrom 480b vs Md Helicopters (mcdonnell Douglas) 902 Explorer

The Bell 525 Relentless and MD Helicopters 902 Explorer are twin‑engine helicopters aimed at offshore, corporate, and utility missions, while the Enstrom 480B is a smaller single‑engine turbine helicopter better suited to shorter trips, training, and light utility work. The Embraer Legacy 650E is a long‑range business jet, optimized for fast intercity and transcontinental travel rather than point‑to‑point access to unimproved sites. In range, the Legacy 650E is the clear outlier, typically capable of roughly 3,900 nautical miles, far beyond any helicopter here. Among the helicopters, the Bell 525 generally offers the longest legs at about 560 nautical miles, the MD 902 Explorer is typically in the mid‑400‑nautical‑mile class, and the Enstrom 480B is shorter still, around the low‑300‑nautical‑mile range depending on configuration and reserves. Passenger capacity also separates them. The Legacy 650E commonly seats around 13 passengers in an executive layout. The Bell 525 is usually configured for roughly 16 to 20 passengers. The MD 902 typically carries about 7 to 8 passengers. The Enstrom 480B is the smallest, commonly accommodating about 4 passengers plus the pilot.
