Bell 525 Relentless vs Boeing Bbj Max 9 vs Dassault Falcon 8x vs Piper M600 Sls
The Bell 525 Relentless is a large, fly-by-wire helicopter aimed at offshore, corporate, and VIP lift. Compared with jets it has much shorter range—roughly in the mid-hundreds of nautical miles depending on payload and reserves—but it can access heliports and confined sites. Passenger capacity is typically around a dozen to the high-teens in airline-style seating, with VIP layouts varying. The Boeing BBJ MAX 9 is an ultra-long-range, large-cabin business airliner conversion. It offers by far the greatest range of this group—typically cited around 6,000+ nautical miles with auxiliary tanks—and the highest capacity, often configured for a few dozen passengers in VIP comfort, or many more in high-density layouts. The Dassault Falcon 8X is a purpose-built long-range tri-jet business jet with intercontinental range (about 6,400–6,450 nautical miles) and a typical executive passenger load around 12–16, optimized for premium comfort rather than sheer headcount. The Piper M600 SLS is a single-engine turboprop, best for owner-operators and short-to-mid trips, with roughly 1,000+ nautical miles of range and seating typically around 4–6 passengers.
