The Antonov An-148 is a regional jet aircraft designed by the Ukrainian Antonov company and produced by Antonov itself and also on outsource by Russia's Voronezh Aircraft Production Association.The An-148 has a maximum range of 2,100–4,400 kilometers and is able to carry 68–85 passengers, depending on the configuration. The Antonov An-158 is a stretched fuselage version of the aircraft, accommodating up to 99 passengers.
The An-148 aircraft is a high-wing monoplane with two turbofan jet engines mounted in pods under the wing. This arrangement protects the engines and wing structure against damage from foreign objects (FOD). A built-in auto-diagnosis system, auxiliary power unit, high reliability, as well as the wing configuration allow the An-148 to be used at poorly equipped airfields. Modern flight and navigation equipment, featuring five 15 cm by 20 cm (6" by 8") liquid crystal display (LCD) panels built by Russia’s Aviapribor and a fly-by-wire system enable the An-148 aircraft to operate day and night, under Instrument flight rules (IFR) and Visual flight rules (VFR) weather conditions on high density air routes. Similar to the Boeing 737, the main landing gear rotates into the belly of the aircraft when in flight, with partial doors covering the legs and the sides of the tires remaining exposed. Other design advantages include the high fuel-efficiency of the Motor Sich D-436-148 engines and entrance stairs that enable boarding and deboarding the plane without extra ground equipment.
