Bell 525 Relentless vs Boeing Bbj Max 9 vs Robinson R66 vs Sikorsky S 92

The Bell 525 Relentless and Robinson R66 are helicopters, while the Sikorsky S-92 is a larger, heavy twin helicopter, and the Boeing BBJ MAX 9 is a long-range business jet airliner derivative. In category terms, the R66 is a light single‑engine helicopter suited to short, flexible point‑to‑point missions; the Bell 525 is a modern medium twin intended for higher-speed corporate and offshore roles; and the S‑92 sits above both as a heavy twin optimized for offshore transport, SAR, and utility work. The BBJ MAX 9 is in a different class entirely, offering intercity and intercontinental-style corporate travel at airline speeds and altitudes. Range is shortest on the R66 (a few hundred nautical miles typical), longer on the Bell 525 (roughly around 500–600 nm class), and similar or slightly higher on the S‑92 depending on fit (often around the 500 nm class). The BBJ MAX 9 far exceeds the helicopters, reaching several thousand nautical miles. Passenger capacity scales similarly: R66 typically carries about 4 passengers, Bell 525 commonly around the low to mid teens, S‑92 commonly around 19 passengers in offshore layouts, while a BBJ MAX 9 can be configured for dozens in VIP layouts (and far more in airline seating).
