DISPLAY SYSTEM  Multi-Functional Display (MFD)
- Multi-Function Display (MFD) provides the pilot with high resolution symbology overlaid on a video image coming from DMG and other interface systems. The MFD is built around a full high resolution, high contrast Active Matrix Liquid Crystal Display (AMLCD) device, allowing pilot to see the display image even under a high ambient light. It has high MTBF, 4 times in comparison to CRT. It displays video images coming from video sources such as RADAR, FLIR, OPTRONICS and Digital Map Generator.
 Pilot Control Unit (PCU) for Helicopters
- Pilot Control Unit (PCU-II) is Human Machine Interface (HMI) of Automatic Flight Control System (AFCS). It provides interface between crew and AFCS.
 Engine & Flight Display Unit (EFDU)
- Engine & Flight Display Unit (EFDU) is LCD display for EFIS system. It displays Air Data, Attitude, Heading information, Engine, fuel and hydraulic parameters information. EFIS is also integrated with avionics system through MIL 1553B bus.
Head Up Display System (HUD)
- Head Up Display (HUD) system is designed to display aircraft symbology in various modes to the pilot. The aircraft symbology is displayed through a combiner lens assembly which displays the symbology superimposed on the external field of view.
 Combined Map and Electronic Display (COMED)
- The Head down display (Combined Map and Electronic Display, COMED-2045) is a cockpit mounted navigational aid with multifunction facilities. It displays the ground map as stored in a filmstrip superimposed with symbols generated in a CRT. The projected map corresponds to the terrain over which the aircraft is flying in the navigational mode. The CRT displays the symbols corresponding to the present position, heading of the aircraft track and direction to the next waypoint. The CRT also provides various other flight parameters such as altitude, air speed, ground speed, time to go to next waypoint etc. Facilities are also available to project flight instrument parameters. The equipment is integrated to the Navigation/Attack system through MIL-STD -1553B bus.
Head Up Display and Weapon Aiming Computer (HUDWAC)
- The Head Up Display and weapon aiming computer, HUDWAC provides the pilot with continuously updated weapon-aiming information accurately superimposed on his forward view of the outside world. The system generates and positions aiming marks and other symbols in a range of attack mode, using data provided by the Inertial Navigation and Attack system (INS) through the MIL-STD-1553B bus.

NAVIGATION SYSTEM  Inertial Navigation and Global Positioning System (INGPS)
- Inertial navigation is a process which allows a vehicle to locate itself in space (position, speed and attitude). INGPS is based on “strap-down” navigation systems. In such systems, all output values are calculated based on information delivered by the angular rotation (Ring Laser gyros) and linear acceleration (accelerometers) detectors. GPS Information is used to compensate the effect of inertial parameters drift, in order to compute optimal navigation data. The INS/GPS (Inertial Navigation System/ Global Positioning System) SIGMA 95 is a Strap down Inertial Navigation Unit (INU) based on Ring Laser Gyro, accelerometers and GPS receiver. It is licensed from M/s Sagem France now M/s Safran Defence & Electronics, France.

It is a standby Inertial Navigation Sensor in case of failure of main INGPS.
 INERTIAL MEASURING BLOCK
- INERTIAL MEASURING BLOCK is meant for determining and sending of components of linear acceleration( aX, aY, aZ) and components of absolute angular speed (wX, wY, wZ ) along mutually perpendicular axes of the aircraft in flight (with X- axis directed along the longitudinal axis of aircraft) for positioning of RADAR antenna. The unit has two dry tuned gyroscopes and three numbers of servo accelerometers.
