Airbus Helicopters H125 vs Airbus Helicopters H130 vs Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H175 vs Bell 429 Globalranger vs Bell 525 Relentless vs Leonardo Aw139

The Airbus H125 and H130 are single‑engine light helicopters; the H125 typically offers the longest range of this group (roughly in the 330–350+ nm class) with about 5–6 passengers plus pilot, while the H130 emphasizes a roomier, quieter cabin for about 6–7 passengers plus pilot with broadly similar but often slightly lower range depending on fit. The Airbus H135, H145, and Bell 429 are light twin‑engine types; the H135 generally seats about 6–7 passengers with moderate range (around the low‑to‑mid‑300 nm class), while the H145 and Bell 429 commonly carry about 7–8 passengers with similar or somewhat better range (often mid‑300 nm class). Moving up, the Airbus H175 and Leonardo AW139 are medium twins: typical cabin payload is about 12–15 passengers with ranges commonly in the 400–500+ nm class depending on tanks and reserves. The Bell 525 is a larger “super‑medium” twin, aimed at about 16 passengers with ranges often around the 500–600 nm class. Actual figures vary by mission kit and regulatory reserves.
