Control Display Subsystem

Introduction

The Control Display Subsystem (CDS) is the primary interface for both Pilot and Copilot to display and control flight and navigation data, communications, sensors and weapons. The CDS is comprised of two Improved Master Controller Processor Units (IMCPUs), two Multifunction Displays (MFDs), one Multifunction Keyboard (MFK), one Remote Frequency Display (RFD), two Optical Display Assemblies (ODAs) and one Personal Computer Data Transfer System (PC-DTS). Other systems linked to the CDS include the Mast Mounted Sensor (MMS), AN/APR-39 Radar Detector Set, AN/AVR-2 Laser Detection Set, AN/ALQ-144 Infra-red Countermeasures Device and the AN/AAR-57 Common Missile Warning System.

Improved Master Controller Processor Unit

The Left and Right Improved Master Controller Processor Units handle all inputs to the CDS and processes and displays data to the various output interfaces.

Multifunction Display

Two Multifunction Displays housed in the instrument display function as the main output device for the CDS. The MFDs operate independently allowing different functions to be performed simultaneously by the Pilot and Copilot.

Each MFD includes fifteen bezel buttons for mode and function selection, a Brightness (BRT) and Contrast (CNT) rocker for adjusting the display picture.

A Manual/NVG Mode selector allows for changing the display image between a daylight setting and an NVG compatible mode.

The Primary/Backup selector allows for selection of the alternate IMCPU as the input source in the event that the primary source fails.

Multifunction Keyboard

The Multifunction Keyboard (MFK) is located on the center console and is available to both crewmembers. Data entry on the MFK is shared between both MFDs and so only a single entry mode may be active at any time.

Numeric keys. Used to enter numerals. A decimal point and minus key are also included
Alpha keys. Used to enter characters
Labelled keys
- IFF. Displays IFF page 1 on the Copilot MFD
- TUNE. No function
- SCAN. No function
- BLANK. Inserts a blank space
- IDNT. Broadcasts IFF identification
ENTER key. Confirms entry of input data. Exact function depends on data entry mode
CLEAR key. Clears all input
CURSOR LEFT/RIGHT keys. Advances/Retreats the cursor. Left key will delete any preceding input. Right key will add a space if at end of input
