The PT-23 is a primary trainer aircraft used during World War II, primarily by the United States Army Air Forces. It was designed to provide basic flight training to pilots and features a low-wing monoplane design. The aircraft is powered by a Continental O-170 engine, which allows for stable flight characteristics and ease of handling. The PT-23 is notable for its tandem seating arrangement, accommodating an instructor and a student pilot. Its simple controls and forgiving flight dynamics made it an ideal choice for training new aviators. The aircraft played a significant role in preparing pilots for more advanced military aircraft during the war.
