Bell 525 Relentless vs Boeing Bbj Max 9 vs Leonardo Aw189 vs Piper M600 Sls

The Bell 525 Relentless and Leonardo AW189 are twin‑engine helicopters suited to vertical access and point‑to‑point missions where runways aren’t available. The 525 is positioned as a long‑range, high‑speed corporate rotorcraft, typically carrying a small executive group, while the AW189 is a super‑medium helicopter optimized for offshore and utility roles with similar or slightly higher seating flexibility depending on interior, generally in the mid‑teens or fewer for VIP use. In range, both helicopters are far shorter than jets, with the 525 broadly comparable to or somewhat exceeding the AW189 depending on configuration. The Boeing BBJ MAX 9 is a large business jetliner derivative, in an entirely different category: it offers intercontinental range and the highest passenger capacity by far, from VIP layouts to airline‑style seating, and is intended for long‑haul travel between major airports. The Piper M600 SLS is a single‑engine turboprop, far smaller and simpler than the others, typically six seats, with solid regional range and the lowest passenger capacity, best for short to mid‑range trips into smaller airports.
