Airbus Helicopters H125 vs Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H155

The Airbus Helicopters H125 is a light single‑engine utility helicopter, typically configured for about 5–6 passengers plus a pilot and known more for lifting and high/hot performance than long-distance travel; its practical range is roughly in the 330–350 nautical mile class depending on fit and reserves. The H135 is a light twin‑engine helicopter oriented toward EMS, law enforcement, and corporate shuttle missions, usually seating about 5–7 passengers (plus crew) with a similar or slightly lower practical range, commonly around 320–340 nautical miles. The H145 steps up into the light‑intermediate twin category with a larger cabin and higher useful load, often configured for about 7–9 passengers (plus crew) and a broadly comparable or slightly better practical range, around 330–360 nautical miles. The H155 is a larger medium twin aimed at offshore support and executive transport, typically carrying about 12 passengers (plus crew) and offering the longest reach of this group, commonly around 450–480 nautical miles, again depending on configuration and mission profile.
