Bell 525 Relentless vs Dassault Falcon 8x vs Piaggio Avanti Evo vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are medium/large twin‑engine helicopters optimized for vertical access rather than runway operations. The 525 is positioned as a modern “super‑medium” helicopter with a typical range on the order of about 500–600 nautical miles and usually carries roughly 12–16 passengers depending on layout. The S-92 is a larger, heavy helicopter commonly used for offshore and VIP missions, generally offering similar or somewhat greater practical range (often around 500+ nautical miles) and seating that can vary widely, from VIP interiors to high‑density configurations that can reach around 19 passengers. The Dassault Falcon 8X is a long‑range, large‑cabin business jet, built for intercontinental missions, with a range around 6,400 nautical miles and typical seating for about 12–16 passengers in executive layouts. The Piaggio Avanti EVO is a fast, pressurized twin‑turboprop aircraft in the light business category, with a range roughly around 1,400–1,800 nautical miles and typically seats about 6–9 passengers.
