- Increase in combat efficiency of the aircraft against ground-based and air targets by deep upgrade of sighting system, implementation of its new operation modes and employment of R-73 missiles and S-13 rockets.
- Extension of combat potentials by provision of 24-hour and all weather capability, expanded range of accomplishable missions owing to use of modern satellite navigation means, advanced navigation modes and state-of-the-art software of sighting navigation systems.
The aircraft is modified for installation and employment of new air weapons as well as placement of new equipment in technical sections.
- 2 color LCD indicators (MFI) with button framing;
- Back-up IRP device intended to back up display of pitch, roll and yaw, heading, speed, altitude and vertical speed.
Installation of HUD indicator instead of S-17VG sighting head enables display of aiming and flight-navigation information (pitch, roll and yaw scale; aiming information; heading and glide path flags; navigation information (desired heading, distance to waypoint, altitude).
Satellite navigation system includes 14-channel receiver operating by the signals of GLONASS (Russia) and GPS NAVSTAR (USA) satellite navigation systems using С/А codes on L1 carrier frequency. The system is intended for determination of current coordinates of the aircraft (latitude, longitude and altitude), speed vector and current time by the signals of GLONASS and GPS navigation systems worldwide at any time and regardless of the weather conditions.
LINS — is small-size strap down navigation system based on of ring-laser gyros (RLG) and pendulum accelerometers.
Inertial navigation system enables automatic measurements of 3D motion parameters (attitude, speed, heading etc). Real time output of the above data in independent (fully inertial) operation mode integrating SNS receiver corrections.
The system enables registration of communication audio signals and video information for objective control and post-flight analysis.
“BUR” flight data recording and processing system is intended for registration, control and storage of information about condition of power plants and aircraft onboard systems.
“DVINA-M” ground-based software system is used to read, process, promptly analyze and display the parameters recorded during the flight.
BKS onboard communication system is intended for ECM-resistant open and encrypted voice and data communications for interaction with other aircraft and ground-based control posts.
«Satellite» ECM protection suite is intended for ECM protection of the aircraft, whatever the type, from precision radio guided weapons launched from enemy airborne interception suites or air defense missile systems.
