Avionics

JF-17 Avionics Architecture will be supported by two mission computers based on around Multi-Bus System (MIL-STD-1553B). The heart of the system is a 32-bit Weapon and Mission management Computer (WMMC) which performs mission computations, flight management, reconfiguration / redundancy management and in-flight system self-test.

The Aircraft will be equipped with advanced  multi-track, multi-mode, pulse Doppler radar for air to air, air to surface attack capabilities. Accurate navigation and guidance is realized through hybrid technology using Ring Laser Gyros (RLG) based Inertial Navigation System (INS) and Global Positioning System (GPS). Independent Data link with 2 Independent Wide-Band Radios will take care of communication even during intense EW environment . EW suite comprises of Self Production Jammer (SPJ), Missile Approach Warning System (MAWS), Radar Warning Receiver (RWR), Chaff & Flare Dispenser (CFD). Laser Designator and Targeting Pod (LDTP) is for target illumination and detection with day/ night capabilities.

Glass cockpit uses Smart Multifunction Color Display (SMFCD) and Smart Heads-Up Display (SHUD) with built in symbol generation capability to optimize integrated architecture. ICP and HOTAS arrangement. Identification of Friend and foe (IFF) implements Secure mode for EW environment. Target verification is with onboard IFF interrogator for BVR missile firing.
