,,LASTA “

"LASTA" aircraft is intended for initial and basic training of pilots and easy transition to the advanced levels of taining. It has low landing and takeoff speeds and pilot-friendly, i. e. it 'forgives' potential errors made by inexperienced pilots.

The aircraft was designed in compliance with Federal Aviation Regulations (F.A.R. – Part 23: Airworthiness Standards), namely:

  • BASIC VERSION OF THE AIRCRAFT is built against the requirements for acrobatic category, for loads of (nz_max = 6.0, nz_min = -3).
  • ARMED VERSION OF THE AIRCRAFT is built against the requirements for utility category, for loads of (nz_ max = 4.4, nz_ min = -1.8).

The aircraft specification and upgraded avionics enable full pilot training for all applications, such as:

  • basic flying,
  • formation flying,
  • air navigation
  • basic elements of night flying,
  • basic elements of instrument flying
  • basic elements of gunning, rocketing and bombing (GRB)

Lasta landing gear is equipped with an emergency landing gear extension system (used in the event of hydraulic system failure). This mechanical system ensures extension and locking of all three struts, at horizontal aircraft speeds of up to 180 km/h.

Structural mass was minimized by applying advanced methods of stress calculation, including numerical simulations, to meet strength and rigidity requirements.The airframe stress test verified the adopted concept and calculations approach.
