Bell 525 Relentless vs Boeing Bbj Max 9 vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Sikorsky S 92

The Bell 525 Relentless is a super-midsize twin‑engine helicopter aimed at corporate and offshore missions. It typically carries around 12–16 passengers in a high-density configuration (often fewer in VIP layouts) and offers a practical range on the order of roughly 500–600 nautical miles, depending on payload and reserves. The Boeing BBJ MAX 9 is a long‑range VIP/business jet derived from the 737 MAX 9 airliner. It sits in a different category entirely, with a large-cabin, intercontinental mission profile. Passenger capacity varies widely by interior, commonly a few dozen in VIP service, while range is roughly about 6,000+ nautical miles with auxiliary fuel provisions. The MD Helicopters (McDonnell Douglas) 902 Explorer is a light twin helicopter used for utility, corporate, and public-service roles. It generally seats about 8–10 people including crew, with a typical range around 300–400 nautical miles. The Sikorsky S‑92 is a heavy twin helicopter designed for offshore transport and SAR. It commonly carries about 19 passengers (more in high-density) and has a typical range around 500–600 nautical miles, payload-dependent.
