Bell 525 Relentless vs Embraer Legacy 650 E vs Piper M600 Sls vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are large, long-range helicopters, while the Embraer Legacy 650E and Piper M600 SLS are fixed-wing business aircraft (a super-midsize jet and a single‑engine turboprop, respectively). In range, the Legacy 650E is typically the longest-legged of the four, suited to long intercity or some intercontinental missions; the Bell 525 offers long range for a helicopter, but generally less than the jet; the S-92 is also long-range for a helicopter but is commonly configured for shorter offshore and utility legs than the 525; the M600 SLS delivers solid regional range but usually trails the large-cabin jet and the longest-range helicopter profiles. For passenger capacity, the S-92 is the highest, often set up to carry large groups; the Bell 525 carries fewer than the S-92 but more than most business aircraft cabins in comfort-focused layouts. The Legacy 650E typically seats around a dozen in executive configuration, and the M600 SLS is the smallest, generally flown with about five to six passengers plus the pilot.
