The '''Pazmany PL-1 Laminar''' and '''Pazmany PL-2''' are [[United States|American]] two-seat trainer and personal light aircraft designed by [[Ladislao Pazmany]] to be marketed as a [[homebuilt aircraft]] by his company [[Pazmany Aircraft|Pazmany Aircraft Corporation]]. The aircraft was built under license in [[Taiwan|Taiwan (Republic of China)]] as the AIDC PL-1B Cheinshou. It was later followed by an improved version the '''PL-2'''. The [[Sri Lanka Air Force|SLAF]] Aircraft Engineering Wing developed a modified variant of the PL-2 in 1977, which was never used operationally. 

==Development==
The PL-1 Laminar was the first design by Ladislao Pazmany, it was intended to be marketed for the homebuilt market. The prototype first flew on the 23 March 1962. The PL-1 is a cantilever low-wing monoplane with a fixed tricycle landing gear. It has side-by-side seating for a crew of two and is powered by a 95&nbsp;hp (71&nbsp;kW) Continental C-90 piston engine. The [[Aerospace Industrial Development Corporation]] (AIDC) acquired plans and built a PL-1 for evaluation with a first flight on 26 October 1968. AIDC then built 58 aircraft designated the '''PL-1B''' for the [[Republic of China Air Force]] and fitted with a 150&nbsp;hp (112&nbsp;kW) Avco Lycoming O-320 engine.

Soon after the first flight Pazmany produced an improved design, the '''PL-2''' which had a slight increase in cockpit width and changes to the structure to make it easier for homebuilders. The PL-2 was evaluated by a number of air forces in South East Asia. It was built under license in Indonesia as the '''LIPNUR LT-200'''.
