Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H155 vs Airbus Helicopters H160 vs Beechcraft King Air 360 vs Bell 525 Relentless vs Leonardo Aw139 vs Piaggio Avanti Evo

The Airbus H135 and H145 are light twin-engine helicopters: the H135 typically carries about 5–7 passengers with roughly 300–350 nm range, while the larger H145 usually seats about 7–9 with similar-to-better range, commonly around 330–370 nm depending on fit. The Airbus H155 steps up to the medium-twin class, often configured for about 8–13 passengers and roughly 450–500 nm range. The Airbus H160 is a newer medium twin with improved efficiency, typically around 8–12 passengers and about 450–480 nm range. The Bell 525 Relentless is a larger “super-medium” twin, commonly about 12–16 passengers with approximately 500–560 nm range. The Leonardo AW139 is a widely used medium twin, typically 10–15 passengers with about 550–600 nm range. By contrast, the Beechcraft King Air 360 is a twin‑turboprop fixed‑wing aircraft, typically 6–9 passengers with roughly 1,500+ nm range. The Piaggio Avanti EVO is a fast twin‑turboprop fixed‑wing aircraft, typically 6–9 passengers with about 1,500–1,800 nm range.
