Bell 525 Relentless vs Daher Tbm 960 vs Piper M600 Sls vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are twin‑engine helicopters aimed at offshore, utility, and VIP missions, while the Daher TBM 960 and Piper M600 SLS are single‑engine turboprop airplanes optimized for fast personal and business travel. In range, the TBM 960 generally leads among the four, typically capable of roughly 1,500+ nautical miles depending on reserves and conditions, with the M600 SLS usually around the 1,000–1,200 nautical mile class. Helicopter ranges are shorter: the Bell 525 is typically in the high‑500 to ~600 nautical mile class, while the S‑92 is commonly in the ~500–600+ nautical mile class depending on configuration. For passenger capacity, the M600 SLS and TBM 960 are usually flown with 1 pilot plus about 5–6 passengers (up to 6 occupants total in many layouts). The Bell 525 is a larger cabin helicopter often arranged for about 12–16 passengers. The S‑92 is larger still, commonly configured around 19 passengers for transport, with VIP layouts varying.
