Airbus Helicopters H135 vs Bell 505 Jetranger X vs Md Helicopters Md 520n vs Md Helicopters Md 600n vs Md Helicopters Md 902 Exlplorer

In category, the Airbus H135 is a light twin‑engine helicopter aimed at multi‑mission work with strong redundancy, while the Bell 505 JetRanger X and MD 520N are light single‑engine helicopters typically positioned for training, utility, and cost‑efficient operations. The MD 600N and MD 902 Explorer move into larger, higher‑capacity roles; the 600N is a medium single (NOTAR anti‑torque) and the 902 is a medium twin (also NOTAR), generally better suited to higher payload and more demanding commercial missions. In range, the H135 and Bell 505 are commonly in a similar general band for light helicopters, often a few hundred nautical miles depending on configuration and reserves, while the MD 520N is typically comparable but often somewhat more limited depending on fit. The MD 600N and MD 902 generally offer longer legs and better cruise efficiency for their size, with the 902 often competitive on mission radius due to twin‑engine power and higher useful load. For passenger capacity, the Bell 505 and MD 520N are usually around 4 passengers plus pilot, the H135 typically carries about 5–6 passengers plus crew, the MD 600N about 6 passengers plus pilot, and the MD 902 commonly about 7–8 passengers plus crew, depending on interior and certification.
