Question: A small small twin-engine jet corporate aircraft was further developed and updated by what brand of Textron Aviation since 2014?
Context: Beechcraft is a brand of Textron Aviation since 2014.  Originally, it was a brand of Beech Aircraft Corporation, an American manufacturer of general aviation, commercial, and military aircraft, ranging from light single-engined aircraft to twin-engined turboprop transports, business jets, and military trainers.  Beech later became a division of Raytheon and later Hawker Beechcraft before a bankruptcy sale turned its assets over to Textron (parent company of Beech's cross-town Wichita rival, Cessna Aircraft Company). Textron Aviation is the general aviation business unit of the Textron group that was formed in March 2014 following the acquisition of Beech Holdings which included the Beechcraft and Hawker Aircraft businesses.  The new business unit includes the Textron-owned Cessna.  Textron Aviation sells Beechcraft and Cessna branded aircraft.  While no longer selling new Hawker airplanes, Textron Aviation still supports the existing Hawker aircraft fleet through its service centers. Airspeed Aviation was a small regional airline based in Abbotsford, British Columbia, Canada.  The airline was in operation since 1986 and was sold to Orca Airways at Vancouver International Airport on February 27, 2009.  They specialized in flying between Abbotsford International Airport and Victoria International Airport, with twin-engine Cessna corporate aircraft.

The Sukhoi Su-57 (Russian: Сухой Су-57 ) is the designation intended for a stealth, single-seat, twin-engine jet multirole fighter aircraft designed for air superiority and attack operations.  The aircraft is the product of the PAK FA (Russian: ПАК ФА , Russian: Перспективный авиационный комплекс фронтовой авиации , "Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii", literally "Prospective Airborne Complex of Frontline Aviation"), a fifth-generation fighter programme of the Russian Air Force.  Sukhoi's internal name for the aircraft is T-50.  The Su-57 will be the first aircraft in Russian military service to use stealth technology.  The fighter is planned to have supercruise, stealth, supermaneuverability and advanced avionics to overcome the prior generation fighter aircraft as well as ground and maritime defences.
