Bell 525 Relentless vs Boeing Bbj Max 9 vs Dassault Falcon 8x vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are long-range, twin‑engine helicopters suited to point‑to‑point access where runways aren’t available. The Bell 525 targets roughly 560 nautical miles of range with typical seating around 16–20 passengers depending on layout, while the larger S‑92 is commonly configured for about 19 passengers with range generally in the 500–600 nautical mile class (mission and payload dependent). The Dassault Falcon 8X is a long‑range business jet designed for intercontinental missions, offering about 6,450 nautical miles of range and typically carrying 12–16 passengers in executive layouts. The Boeing BBJ MAX 9 is a VIP airliner based on the 737 MAX 9, prioritizing cabin volume over speed-to-airport access. It offers roughly 6,300+ nautical miles of range (configuration dependent) and can be outfitted for a wide span of VIP capacities, often around 25–50 passengers, with the ability to go higher in denser layouts.
