Bell 525 Relentless vs Pilatus Pc 24 vs Piper M600 Sls vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are helicopters, while the Pilatus PC-24 and Piper M600 SLS are fixed‑wing airplanes, so they serve different mission profiles. For range, the Pilatus PC-24 is generally the longest‑leg option, typically around 2,000 nautical miles class depending on load and reserves, making it well suited to longer point‑to‑point business trips. The Piper M600 SLS is a single‑engine turboprop with a shorter, mid‑range mission, roughly around 1,400 nautical miles class, oriented toward efficient personal or small‑team travel. The Bell 525 is a long‑range super‑medium helicopter, typically around 500–600 nautical miles class, aimed at offshore, executive, and utility missions with vertical access. The Sikorsky S-92 is a larger heavy helicopter, commonly in the 500–600 nautical miles class as well, optimized for offshore transport and SAR-style capabilities. In passenger capacity, the PC-24 is typically configured for about 6–10, the M600 for about 4–6, the Bell 525 for roughly 12–16 depending on layout, and the S-92 for about 16–19 in typical transport configurations.
