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.

JF-17 has quadruplex, digital, fly-by-wire flight control system and two hydraulic systems for backup.

Pakistan has selected KLJ-10 for the first batch of 50 aircrafts. PAF is also seriously considering RC-400 from France for the next batch.

Information on Radars:

NRIET KLJ-7/10 (Type 1478):
This radar is probably a variant of the radar used in J-10. It has met PAF's requirements and therefore has been chosen for initial batch. Other reasons that could have influenced the selection of a Chinese radar are the future induction of Chinese AEW&C, SD-10 (Easier integration) and lower costs. The radar can manage upto 40 targets, monitor 10 in TWS mode and engage upto 2 BVR targets simultaneously.
A target with 3m^2 can be detected at 120 km or 50km in LD mode. Surface Sea targets can be detected at ranges upto 135km.

THALES RC-400:
RC-400 is a compact, modular, lightweight, power efficient and multi-platform radar. The radar is based on technology from RDY-2 radar used in Mirage 2000-5 and 2000-9. The RC-400 includes track-while-scan, smart automatic management of scanning and target prioritisation. This allows for accurate, multiple fire-and-forget capability, along with the datalink requirements for missile control. Upto 24 targets can be tracked, 8 can be targeted simulataneously and 4 can be automatically prioritized. RC400's modularity allows it to increase of decrease its capabilities depending upon the requirements of the customer.
