Bell 525 Relentless vs Daher Tbm 960 vs Embraer Legacy 650 E vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at executive and offshore missions. It typically carries about 16 passengers in high-density layouts (fewer in VIP), and its practical range is roughly in the 500–600 nautical mile class depending on configuration and reserves. The Daher TBM 960 is a single‑engine pressurized turboprop airplane optimized for fast owner‑pilot travel. It usually seats 4–6 passengers plus a pilot (up to about 6–7 seats total depending on interior), and offers long legs around 1,400–1,700 nautical miles depending on speed and payload. The Embraer Legacy 650E is a large‑cabin, long‑range business jet with true multi‑zone comfort. It typically accommodates 13 passengers (up to about 14), and flies about 3,900 nautical miles, making it the clear range leader here. The Piper M600 SLS is a single‑engine pressurized turboprop positioned below the TBM in speed and size. It generally seats 5–6 passengers plus a pilot, with range roughly around 1,000–1,400 nautical miles depending on power settings and load.
