Oscar: Seriously bro, do take the effort of organizing the parts/components/tech by Pakistan in Jf-17 into a separate list/thread. It would be really helpful. If such a thing exists,please point us to it. Thank You.
Well, the teams are on it. As such a start can be the PAC website to figure out what comes and goes from where.
So for a start in avionics that are total Pakistani
DESIGN input and not a collaborative design or IP if that is.
Global Attitude Heading reference System (GAHRS)
Global Attitude Heading Reference System (GAHRS) is an avionics subsystem of JF-17 aircraft which provides high performance measurement of aircraft attitude by using highly reliable optical fi ber gyroscopes and accelerometers. GAHRS is a backup system of Inertial Navigation System (INS). In case of INS failure, it provides roll, pitch and heading information to Weapon Mission Management Computer (WMMC) using RS 422 interface
Integrated Survivable Recorder (ISR)
Integrated Survivable Recorder (ISR) is an important LRU of aircraft Electro Mechanical Management System (EMMS). It receives flight and audio data being sent from electromechanical management computer through HDLC bus and records them in crash survival memory unit (CSMU). After recording the data in accordance with the bus commands, it downloads the recorded data and sends it to electromechanical management computer.
Light Warning System (LWS)
Light warning system is used to display emergency warning signals. It's main purpose is to draw the pilot's attention to the warning signals for a proper timely action. It has a Built in Test Function for checking its serviceability and provides four warning levels according to degree of emergency related to flight safety and mission plan.
Stores Management System (SMS)
SMS is able to manage and control guns, bombs, external tank and stores such as armament at stations and pods which comply with MIL-STD-1760C-97. It also ensures that stores functions are carried out in addition to offering certain safety measures.
Smart Head Up Display (SHUD)
SHUD is an integrated electro optical display unit, and is one of the important units of aircraft. It is the main window which provides fl ight and combat information to the pilot. It employs command control mode to generate fl ight symbology required in navigation and combat. The displayed symbology are imaged to infi nity and superimposed with outside scene, enabling the pilot to view the displayed information without adjusting eyes while observing the outside scene. The unit is NVIS compatible. It outputs superimposed video signals for recording, so as to provide evidences for combat and training analysis.
Instrument Landing System (ILS)
ILS is used for aircraft approach and landing. It receives and processes the signals transmitted from ground localizer and glide-slope stations. It provides pilot deviation information from the given course and glide path so as to lead aircraft to the visual runway entrance according to the correct path track. The equipment is one of the essential systems which ensures safe landing of the aircraft under adverse weather conditions.
Back Up Acquisition Computer (BAC)
BAC is a back up computer for avionics systems and provides fl ight critical information to the pilot in case of main bus / mission management computer failure. BAC accepts data from fl ight critical systems on a separate RS 422 data line and communicates the same to Multi Function Displays. It also provides excitation voltage to hydraulic and brake sensors.
Inertial Navigation System (INS)
Radar Altimeter provides data on 1553 Bus pertaining to aircraft actual height above ground level. This data can be displayed on Head Up Display (HUD).
Smart Multi Function Colour Display (SMFCD)
SMFCD is a NVIS compatible display providing the graphical interface of the avionics & non-avionics systems to the pilot. Input to SMFCDs are 1553B data bus, RS-422 XGA In/out and RGB Video Out.
Central Supression Unit (CSU)
Aircraft are equipped with multiple avionics systems consisting of both active and passive systems. It requires an intelligent electromagnetic management system which can ensure co-existance of high power transmitters and high sensitivity receivers. Central Suppressor Unit (CSU) ensures optimum utilization of electromagnet spectrum on board JF-17 aircraft.
Weapon Mission Management Computer (WMMC)
WMMC is a central computer for JF17 aircraft avionic system control and management. The basic tasks of WMMC are multiplex data bus communication management, mission planning and fl ight program management, fi re control calculation, navigation assistance, audio alarming, integrated display managing (including digital map display control) and pilot interface control for avionics systems.
Electro Mechanical Management Computer (EMMC)
EMMC has the capability of communicating with Non-avionics systems of JF-17 aircraft. The computer collects data from various aircraft systems (air data sensors, fuel system, engine, etc). It also monitors electro mechanical systems and carries out data management/ transmission.
Data Transfer Unit (DTU)
Data transfer unit is an avionicssub system of JF-17 aircraft. DTU is used for mission planning, subsystem initialization and recording of vital inflight operational and technical data. Data transfer unit communicates with mission computer. It uploads the mission planning data to avionics sub-systems and retrieves in flight data via Rs422 interface. Retrieved data is used for operation and technical analysis.
Digital Video Recorder (DVR)
Audio Control Box (ACB) is the hub of audio signals management. It receives audio signals from on-board systems like mission computer, communication, navigation and weapon systems and routes these audio signals to pilot headset / recording systems.
Audio Control Box (ACB)
Audio Control Box (ACB) is the hub of audio signals management. It receives audio signals from on-board systems like mission computer, communication, navigation and weapon systems and routes these audio signals to pilot headset / recording systems.
Up Front Control Panel (UFCP)
UFCP is a man-machine interface (MMI) for the avionics sub-systems in JF-17 aircraft. The basic functions include setting, altering and displaying the navigation/communication system's parameters. It communicates with Weapon and Mission Management Computers (WMMC) via RS 422 communication link.
Avionics Activation Panel (AAP)
AAP is used to simplify pilot's operation by centrally activating / deactivating avionics subsystems in JF-17 aircraft. It has the provision for individual or group activation of avionics sub-systems.
In other cases the design input varies to anything from nill to 60%. The JF-17 DOES NOT carry ONLY Chinese systems. As such there are components from sources including the US, South Africa, Germany, South Korea , Italy and other countries whose representatives off and on helped in the integration and inclusion of these components into the aircraft.
