It can be installed in combat-trainer versions of these aircraft, and is adapted for powering other existing trainers, combat-trainers, and those under development to be used as light attack aircraft. In this connection a combat power rating with enhanced maximum thrust for strike combat operations was introduced, and engine acceleration time was substantially reduced. < < < < < < < high reliability which ensures maximum operational safety proven by the fact that nearly 5 000 units of AI-25TL are operated in 37 countries of the world, their total operating time exceeds 6 000 000 hours; high gas-dynamic stability at external disturbances including those resulted from launching onboard weapons; high fuel efficiency; insignificant labour and time expenditures for maintenance; minimum life cycle cost. The automatic control system of previous design is implemented for retrofitting earlier produced L-39 and JL-8 aircraft. At the Customer's demand the engine can be modified to be automatically controlled by a FADEC-type system.
