11. Distance Measuring Equipment – DME MKII DME (Distance Measuring Equipment) is a polar coordinate type radio air navigation system that provides an aircrew with range information on the ARINC 429 Bus for display on the MFD. The range in nautical miles indicates the distance of the aircraft from the surface beacon.  
12. Distance Measuring Equipment – DME MKII DME (Distance Measuring Equipment) is a polar coordinate type radio air navigation system that provides an aircrew with range information on the ARINC 429 Bus for display on the MFD. The range in nautical miles indicates the distance of the aircraft from the surface beacon.  
13. Tactical Air Navigation- TACAN MKII TACAN MKII (tactical air navigation) is a polar coordinate type radio air navigation system that provides an aircrew with range and bearing (azimuth) information on the MIL-STD-1553B Bus for display on the Mission Computer/ Display. Using this information pilot can fly directly to the particular location or to use the bearing and distance from a specific beacon to fix his geographic location. The range in nautical miles indicates the distance of the aircraft from the surface beacon in T/R Mode and from the other aircraft in A/A Mode. The bearing indicates the direction in degrees with respect to magnetic north in T/R and REC Modes  
C Identification
14. Identification of Friend or Foe (IFF) Transponder- IFF Mk X, XI & XII Series Identification of targets for as Friend or Foe in Mk X, XI & XII modes.

17. Radio Altimeter – RAM 27xx Series Measures of vertical height of the aircraft with respect to terrain up to 20,000 feet with 1% accuracy. MIL 1553B, RS422 and ARINC 552A analog output. Unit weight 3.5Kg.  
18. Automatic Flight Control computer – AFCC Automatic Flight control computer is a modular construct and is interfaced to varioussensors, cockpit controls and actuators. The commands computed from both channels isused to drive pitch, roll, yaw and collective axis in series & trim actuators.  
19. IntegratedControl Computer – ICC The ICC perform the guidance, Navigation and control (GNC) functions to ensure a safe and successful flight/mission under the stated operating conditions. The ICC will be interfaced with various cockpit panels, IFCS sensors, utility, actuators and other Avionics LRUs  
20. Data & Video Recording System – DVRS DVRS records three video input channels (Two DVI & one RGB), two audio input channels, two 1553B bus channels and two RS422 channels for a duration of 8 hrs continuously in 128GB Removable Memory Module (RMM). It also has a provision for Loading and dumping of Mission planning data between MC and DVRS through Ethernet interface.  
21. Solid State Data & Video Recording System – SSDVRS SSDVRS records six video input channels, two audio input channels, two 1553B bus channels and two RS422 channels for a duration of 4 hrs continuously in 128GB Removable Memory Module (RMM). System has one video output with dual redundant for in flight replay of selected video channel.  
22. Solid State Weapon Control System – SSWCS Solid State Weapon Control System (SSWCS) is designed for the management of weapon stores on JAGUAR A/c. The system is capable of configuring the weapons and provide release controls for smart weapons and classical weapons (Bombs, Rocket Pods and Fuel-tanks) in normal mode and emergency mode  
23. Voice Activated Command System(VACS) Voice Activated Command System (VACS) recognizes the pilot voice commands and sends the respective code to Onboard computer on MIL STD-1553B bus.
