Bell 412epi vs Bell 429 Globalranger vs Bell 525 Relentless

The Bell 412EPi is best viewed as a proven utility helicopter in the medium twin category, optimized for rugged missions and external-load work. Its practical range is in the mid-hundreds of nautical miles (roughly around 350 nm, configuration dependent) and it typically carries about 10–13 passengers, with higher counts possible in high-density layouts. The Bell 429 GlobalRanger is a lighter, faster, more corporate/EMS-focused light twin. It generally offers a similar “few-hundred nautical mile” mission radius (often around 390–410 nm depending on fuel and reserves) but with a smaller typical passenger load, commonly around 6–7 passengers in executive seating, or more in utility/EMS configurations. The Bell 525 Relentless moves into the super-medium class, aimed at longer-range offshore and high-end transport. It is designed for a longer reach (often cited around the 500–600 nm class, configuration dependent) and a larger cabin suited to roughly 12–16 passengers, depending on layout and mission equipment.
