Airbus Helicopters H225 vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Piper M600 Sls

The Airbus H225 and Bell 525 Relentless are long-range, twin‑engine helicopters aimed at offshore, SAR, and VIP missions, while the Boeing BBJ MAX 9 and Piper M600 SLS are fixed‑wing business aircraft serving very different tiers of travel. In category and scale, the H225 is a heavy helicopter and typically carries around 19 passengers in high‑density seating (fewer in VIP), with a range roughly in the 450–650 nm class depending on payload and tanks. The Bell 525 is a super‑medium helicopter, generally configured for about 16–20 passengers, with a broadly similar medium‑to‑long helicopter range, often cited around 500–600 nm depending on mission profile. The BBJ MAX 9 is an airliner‑based VIP jet: range is on the order of about 3,200–3,600 nm depending on configuration, and passenger capacity varies widely, from spacious VIP layouts (dozens) up to airline‑like seating well over 150. The Piper M600 SLS is a single‑engine turboprop: it seats up to 6, with roughly 1,300–1,500 nm range.
