The Airbus Helicopters H125 is a light single‑engine helicopter typically used for utility and sightseeing; it generally carries about 5–6 passengers and offers a practical range in the ~330–350 nm class depending on configuration. The H145 is a light twin‑engine helicopter aimed at EMS, corporate, and offshore support; it commonly seats about 8–9 passengers and has a similar to somewhat higher typical range around ~330–360 nm. The H155 is a medium twin positioned for executive and offshore missions, usually carrying about 12 passengers with range often around ~430–470 nm. The H175 is a super‑medium twin optimized for offshore and SAR, generally seating about 16 passengers and offering longer legs, often ~540–600 nm. The Cessna Caravan and Grand Caravan EX are single‑engine turboprop fixed‑wing aircraft focused on rugged regional transport. Both are typically configured for up to 9 passengers (plus pilot), with range commonly around ~900–1,000 nm; the Grand Caravan EX is essentially the higher‑power, higher‑gross‑weight variant, better for hot/high and heavier payloads, with similar or slightly improved real‑world range depending on load.
