Airbus Helicopters H135 vs Leonardo Aw139 vs Leonardo

Aircraft can be compared first by category, which broadly reflects size, mission, and typical operators. Light general-aviation aircraft and small turboprops serve personal travel and short regional hops, while regional jets connect smaller cities to hubs. Narrow-body airliners dominate high-frequency domestic and short-to-medium international routes, and wide-body airliners are optimized for long-haul flying and high passenger throughput. Business jets span several sizes but generally prioritize speed, flexibility, and access to smaller airports over seat count. Range tends to increase with aircraft size and fuel capacity, but also depends on payload and mission. Small piston aircraft may be suited to short trips, turboprops and regional jets commonly cover short-to-mid routes, narrow-bodies can handle medium ranges with some variants capable of longer sectors, and wide-bodies typically provide the longest reach for intercontinental flights. Passenger capacity follows a similar progression. General-aviation aircraft often carry 2–6 passengers, small turboprops and regional jets roughly 30–100, narrow-bodies about 150–240, and wide-bodies commonly 250–400+, with high-density configurations exceeding that.
