jetliner

A jetliner is a fixed-wing air transport aircraft powered by jet engines, designed for carrying passengers or cargo on scheduled airline routes. Jetliners are distinguished from propeller-driven aircraft by higher cruise speeds, greater altitude capability, and longer range.

Most modern jetliners use turbofan engines, which provide thrust with high bypass ratios to improve efficiency and reduce noise. Jetliners range from narrow-body, single-aisle jets to wide-body, twin-aisle airliners, including models such as the Airbus A320 family, Boeing 737, and the larger Airbus A350, Boeing 787, and Boeing 777. Some designs, such as the Airbus A380, are double-deck wide-body jets. They are typically configured with pressurized cabins and complex cockpit avionics, and many incorporate fly-by-wire controls and advanced lightweight materials.

Development of jetliners began in the 1950s with early jet-powered airliners like the de Havilland Comet and the Boeing 707, which opened the jet age and enabled faster, longer-range travel. Subsequent decades brought advances in engines, aerodynamics, materials, and systems that improved efficiency, reliability, and comfort, cementing jetliners as the backbone of commercial aviation and air cargo.

Operations and markets: jetliners are operated by airlines and cargo carriers worldwide. Production and program leadership have historically been dominated by Boeing and Airbus, with newer programs from other manufacturers such as COMAC and Sukhoi/Mikoyan in various stages of development and market penetration.
