The Airbus H225 is a long‑range twin‑engine helicopter aimed at offshore transport, search and rescue, and utility missions. It typically carries around 19 passengers in an all‑seats layout and offers roughly a 450–500 nautical mile range depending on configuration and reserves. The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft optimized for efficient regional and special‑mission flying; it commonly seats about 9–11 passengers and can reach roughly 1,500–1,800 nautical miles with its extended‑range fit. The Bell 525 Relentless is an advanced fly‑by‑wire, super‑medium helicopter designed for offshore and VIP roles; it generally accommodates about 16–20 passengers and targets around 500–560 nautical miles of range. The Gulfstream G700 is an ultra‑long‑range business jet focused on high‑speed intercontinental travel; typical executive layouts seat about 13–19 passengers (with higher maximums possible) and its range is about 7,500 nautical miles, far exceeding the others.
