The Airbus H135 and H145 are light twin-engine helicopters typically used for EMS and utility work; they carry about 5–8 passengers depending on interior, with typical mission ranges roughly in the 300–350 nm class. The Bell 429 GlobalRanger sits in a similar light-twin category with a comparable 6–7 passenger cabin and broadly similar range, often around 300–400 nm depending on reserves and configuration. Moving up, the Airbus H155 is a medium twin with a noticeably larger cabin, commonly configured for about 8–12 passengers and offering longer legs, often around 400–500 nm. The Sikorsky S-76D is also a medium twin frequently used for corporate and offshore transport, generally seating about 8 passengers and typically offering around 350–450 nm of range. The Airbus H160 is a newer medium twin aimed at higher efficiency and comfort, usually configured around 8–12 passengers with range commonly in the 450–550 nm bracket. At the larger end, the Bell 525 Relentless is a super-medium twin designed for offshore and executive missions, typically 12–16 passengers with longer range, often about 500–600+ nm depending on fit and reserves.
