Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Daher Tbm 960 vs Leonardo Aw189

The Bell 525 Relentless and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore, corporate, and utility missions; both sit in the medium helicopter category. The AW189 is typically configured for more passengers, commonly around 16–19, while the Bell 525 is often in the mid‑teens depending on cabin layout. In range, both are broadly comparable for their class, generally in the several‑hundred‑nautical‑mile bracket, with exact figures varying by payload and reserves. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility airplane, optimized for rugged, short‑field operations and cargo/passenger flexibility. It usually carries about 9–14 passengers and offers a longer airplane‑type range than most helicopters, commonly around 900–1,000+ nautical miles depending on configuration. The Daher TBM 960 is a high‑performance, single‑engine turboprop business aircraft. It carries up to about 6–9 occupants (typical executive layouts fewer) and delivers the longest range of the four, often around 1,400–1,700 nautical miles, prioritizing speed and efficiency over cabin capacity.
