Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Pilatus Pc 24 vs Robinson R66

The Bell 525 Relentless and the MD Helicopters 902 Explorer are twin‑engine helicopters, while the Robinson R66 is a lighter single‑engine helicopter; the Pilatus PC‑24 is a twin‑engine fixed‑wing business jet, so it competes in a different category focused on speed and long-distance travel. In range, the PC‑24 generally leads by a wide margin, designed for cross‑country and international legs, whereas the Bell 525 is typically next, offering long helicopter-range capability for offshore, corporate, or utility missions. The MD 902 usually provides a moderate range suited to EMS, law enforcement, and corporate shuttle work, and the R66 tends to have the shortest range among these, optimized for shorter missions and lower operating costs. For passenger capacity, the Bell 525 is the largest here, commonly configured for roughly a dozen-plus occupants depending on layout. The MD 902 generally carries a mid‑single‑digit to around eight passengers. The PC‑24 typically seats around 6–10 passengers in executive configurations. The R66 usually accommodates about 4 passengers plus a pilot.
