Beechcraft King Air 360 Er vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Cessna 208b Grand Caravan Ex

The Beechcraft King Air 360ER is a pressurized twin‑turboprop business aircraft in the light/medium utility category, typically carrying about 6–9 passengers with a long turboprop range of roughly 1,500–1,800 nautical miles depending on payload and conditions. The Cessna 208B Grand Caravan EX is a single‑turboprop utility aircraft optimized for rugged, short‑field operations, usually seating about 9–14 passengers, with a shorter practical range commonly around 900–1,200 nautical miles. The Bell 525 Relentless is a super‑medium helicopter aimed at offshore and corporate transport, generally accommodating about 12–16 passengers, with a range on the order of 500–600 nautical miles, trading speed and runway independence for shorter legs than fixed‑wing aircraft. The Boeing BBJ MAX 9 sits in a different class entirely: a large, long‑range VIP airliner. While airline layouts seat well over 200, BBJ interiors are typically configured for far fewer—often a few dozen to around 50—prioritizing space and amenities, with intercontinental range roughly around 6,000+ nautical miles.
