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

The Airbus H135 and H145 are twin‑engine light helicopters aimed at EMS, law enforcement, and utility work, with the H145 being the larger and longer‑legged of the two. In typical configurations, the H135 carries about 5–7 passengers (plus pilot) and offers a mid‑300 nm class range, while the H145 commonly seats about 8–9 passengers (plus crew) and reaches roughly the mid‑300 to low‑400 nm range depending on tanks and fit. The Bell 505 JetRanger X is a single‑engine light helicopter optimized for training, patrol, and light utility, usually carrying 4 passengers plus pilot and offering around the mid‑300 nm range. The MD 520N and MD 600N are single‑engine light helicopters using the NOTAR anti‑torque system, often favored for quiet operations and patrol/utility roles. The MD 520N typically carries 4 passengers plus pilot with a range roughly in the high‑200 to low‑300 nm class, while the larger MD 600N generally carries about 5–7 passengers (plus pilot) with a similar or slightly higher low‑300 nm class range depending on configuration.
