Beechcraft Baron G58 vs Piper Seneca vs Beechcraft Kingair C90gtx

Aircraft can be compared first by category, which broadly reflects size, speed, and typical mission. Light general-aviation aircraft and turboprops are used for short regional hops, offering lower operating costs and access to shorter runways. Regional jets sit between turboprops and mainline airliners, prioritizing speed and passenger comfort on shorter routes. Narrow-body airliners handle the bulk of domestic and near-international travel, balancing efficiency with higher frequency. Wide-body airliners are designed for long-haul operations, carrying more passengers and cargo with greater fuel capacity and range. Range generally increases with aircraft size and fuel capacity, but also with aerodynamic efficiency and engine technology. Small piston aircraft may cover a few hundred to around 1,000 nautical miles, turboprops and regional jets often reach roughly 800 to 2,000 nautical miles, narrow-bodies commonly span about 2,500 to 4,000+ nautical miles, and wide-bodies frequently operate in the 6,000 to 8,000+ nautical mile class. Passenger capacity scales similarly: small GA aircraft typically carry 2–6 people, turboprops and regional jets about 30–100, narrow-bodies roughly 140–240, and wide-bodies commonly 250–400+ depending on layout.
