Aero, the Czech aircraft manufacturer, has reached a significant milestone in the development of its new L-39NG trainer aircraft. The company has successfully flown the first series-produced L-39NG, a new historical achievement in aviation, 20 years after the last mass-produced aircraft was flown. During the test flight, the pilots evaluated the trainer aircraft’s functions, behavior, and performance within the scope of the standard factory sortie program.
The first production flight of the L-39NG lasted approximately 40 minutes, and the pilots verified the functions of the engine, aircraft systems, and avionics, as well as the handling and behavior of the aircraft in all phases of flight. Testing was carried out in the range of altitudes from 0 to 8,500 meters and speeds from stall to maximum (Mach number 0.8 or 900 km/h).
