Airbus Helicopters H175 vs Airbus Helicopters H225 vs Leonardo Aw609 Tiltrotor vs Piaggio Avanti Evo

The Airbus Helicopters H175 and H225 are both medium-to-heavy twin-engine helicopters aimed at offshore transport, search and rescue, and utility missions. The H175 typically seats around 16 passengers in an offshore layout and offers moderate-to-long helicopter range, roughly in the 500–700 nautical mile class depending on payload and reserves. The larger H225 generally carries more people, commonly around 19 passengers offshore, and provides similar or slightly greater practical mission radius with stronger lift margins, especially in hot-and-high or overwater IFR profiles. The Leonardo AW609 is a tiltrotor, bridging helicopter and turboprop categories. It cruises much faster than either helicopter and targets point-to-point regional missions with vertical takeoff/landing capability; cabin capacity is typically up to 9 passengers, with range roughly around 700–800 nautical miles depending on configuration. The Piaggio Avanti EVO is a pressurized twin-turboprop airplane (not VTOL). It carries about 7–9 passengers, delivers the longest range of the four in many executive configurations (often about 1,200–1,500 nautical miles), and offers the highest cruise efficiency for runway-to-runway travel.
