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 H145 is a light twin helicopter best suited to short-to-medium missions; it typically carries about 6–8 passengers with a practical range around 300–400 nm depending on fit and reserves. The Airbus H155 steps up to the medium class, usually seating about 8–12 passengers and offering roughly 450–600 nm range. The Airbus H160 is a newer medium twin with similar 8–12 passenger layouts and generally comparable or slightly better range, often around 450–600+ nm. Bell’s 525 Relentless and Leonardo’s AW139 sit in the super‑medium class, aimed at longer legs and higher payload; both commonly carry about 12–16 passengers, with typical ranges roughly in the 500–700 nm band depending on configuration. The Beechcraft King Air 360 and Piaggio Avanti EVO are twin‑turboprop airplanes rather than helicopters, optimized for longer range and faster cruise. The King Air 360 generally seats about 6–9 and can reach roughly 1,500+ nm, while the Avanti EVO typically carries about 6–8 with a similar ~1,500–1,800 nm class range.
