Airbus Helicopters H135 vs Airbus Helicopters H145 vs Bell 505 Jetranger X vs Daher Tbm 910 vs Md Helicopters Md 520n vs Md Helicopters Md 600n

The Airbus H135 and H145 are twin‑engine light helicopters; the H135 typically carries about 5–7 passengers with a practical range around 300–350 nm, while the larger H145 commonly seats about 8–9 passengers with a similar or slightly longer range roughly 330–370 nm depending on fit and reserves. The Bell 505 JetRanger X is a single‑engine light helicopter, generally configured for 4 passengers (5 seats including the pilot) with an approximate range around 300–330 nm. The Daher TBM 910 is a single‑engine turboprop airplane rather than a helicopter; it typically carries 4–6 passengers (up to 6 seats plus pilot) and has a much longer range, commonly around 1,500–1,700 nm. The MD 520N and MD 600N are single‑engine NOTAR helicopters; the 520N is a light utility type usually carrying about 4 passengers (5 seats including pilot) with roughly 250–300 nm range, while the larger 600N often carries about 5–7 passengers with a similar or modestly greater range around 300–350 nm.
