AT-3 Tzu Chung

The AT‑3 Tzu Chung is a twin‑engine jet trainer developed by Taiwan’s Aerospace Industrial Development Corporation (AIDC) in the 1980s to replace aging piston‑engine trainers and provide an indigenous solution for advanced pilot instruction. Development began in 1980 under the designation AIDC P‑3, and the first prototype rolled out in 1984, achieving its maiden flight on 24 February 1985. Production continued through 1990, delivering 72 aircraft to the Republic of China Air Force, with later export attempts to Saudi Arabia.

Key features include a low‑wing monocoque fuselage, two Garrett TFE731‑3 turbofan engines delivering 3,400 lbf thrust each, and a cantilevered wing with leading‑edge slats and double‑slotted flaps, giving the AT‑3 a respectable stall speed and short‑field capability. The pressurized cockpit is equipped with modern avionics such as a head‑up display, flight‑control computers, and a glass panel that can emulate radar and weapons systems, allowing seamless transition to front‑line combat aircraft.

Its significance lies in showcasing Taiwan’s ability to design and produce a sophisticated jet trainer domestically, reducing reliance on foreign suppliers and providing a platform for pilot conversion to aircraft like the F‑CK‑1 Ching Kuo and Mirage 2000. The AT‑3 remains a cornerstone of Taiwan’s syllabus and showcases AIDC’s expertise.
