The Airbus H135 is a light twin in the short/medium-range category, typically carrying about 5–7 passengers (plus crew) with roughly 300–350 nm class range depending on fit and reserves. The Leonardo AW169 is also a light twin but larger, often configured around 6–8 passengers with a similar mid-300 nm class range, while offering more cabin volume than the H135. Moving up, the Leonardo AW139 is a medium twin, commonly arranged for about 10–15 passengers and generally in the ~500–600 nm class range. The Airbus H175 sits in the super-medium class, typically carrying around 12–16 passengers with roughly ~500–650 nm class range. The Bell 525 Relentless targets the super-medium segment as well, with a typical passenger count in the mid-teens and an advertised long-range capability around the ~600–700+ nm class depending on mission profile. At the larger end, the Leonardo AW189 is a heavy/“super-medium to heavy” offshore-focused twin, usually configured for about 16–19 passengers with roughly ~450–550+ nm class range depending on payload and reserves.
