Abstract: The method for the estimation and results of the turboprop, armed, COIN (Counter Insurgency) LASTA aircraft performances is presented in this paper. Turboprop LASTA is optimal constructive solution for modernizing and improving LASTA aircraft with piston-engine. Its primary role would be counter insurgency, intelligence, surveillance and reconnaissance. Turboprop (COIN) LASTA aircraft can be equipped with cameras and sensors. For combat  turboprop LASTA can be equipped with: machine guns, rockets, bombs and other "useful cargo". "TURBOLASTAPERF" computer program is used for the calculation of basic and special performances. Program "TURBOLASTAPERF" calculates takeoff, minimum speed, climb, cruise, endurance, maximum speed, turn, landing and flight profiles. Method and its results are illustrated by numerical example. Computer program "TURBOLASTAPERF" is programmed in MATHCAD 14.

Keywords: turboprop aircraft, turboprop-engine, performances, take-off, landing, computer program.
