Integrated Instrument Display System (IIDS)

The IIDS System provides essential aircraft Engine and System Performance on an easy to read Liquid Crystal Display utilizing the latest flat panel display technology.

FEATURES

    DISPLAY: Two LCD displays readable under all cockpit light conditions.

    CONFIGURATION: Two identical displays mounted vertically or horizontally in an enclosure. Independent and Panel Mounted Displays (with remote generation) are also available.

    LIGHTING: Accepts aircraft lighting power input is 5V, 2.0 watts max.

    ELECTRICAL: Interfaces to aircraft, 28 VDC, 50 watt max, power inputs. EMI/RFI protection provided.

    MAINTENANCE: Provides maintenance information on loss of input or processor. Built-in Test Equipment (BITE) for crew confidence testing and continuous in-flight monitoring.

    ON-BOARD EXPERIENCE: Bell 412, Bell 427, Bell 430 Sikorsky S76, Canadair CL-415, CASA 212, CASA 235, CASA 295, Zeppelin NT

Integrated Instrument Display System (IIDS)

    The Integrated Instrument Display System (IIDS) consists of two identical independent units. Each unit uses fully independent computers that process all incoming inputs, exchange data via a digital bus, and maintain control of all outgoing signals while displaying non-critical and essential aircraft status information to the crew. The IIDS is related to Rogerson Kratos' EFIS Product Line that utilizes the same flat panel LCD technology and many of the same internal components.

    The Integrated Instrument Display System technology is an electronic outgrowth of our successful development, performance, and manufacture of our black and white dichroic COINS Product Line used on multiple aircraft throughout the aircraft industry.

System Description

    The IIDS indicator/display modules are capable of performing various system maintenance tasks. These system tasks include continuous self test and storing failure data in non-volatile memory. The IIDS is designed to perform the following functions:

    • Engine instrument indications
    • Fuel quantity indications
    • Hydraulic system indications
    • Electrical system indications
    • Caution & Warning messages
    • Engine exceedence recording
    • OAT and TIME (GMT, LOCAL, etc.)
    • Mast torque indications (Helicopter Applications)
      • Chip detector warning and "Fuzz Burner" outputs (Helicopter Applications)
    • FADEC interface capability
      • Weight and Balance


    The system also provides reversionary operation. If there is a display failure due to a malfunction within the signal processor unit, data bus damage or the display itself, the pilot may select the reversionary formats to display on the remaining screen.

Two Separate Identical Units

    The Integrated Instrument Display System (IIDS) consists of two indicator/display units which are housed in one integrated panel. These units can be mounted horizontally, as in the Bell 430 helicopter, or vertically, as in the Bell 427. Each unit uses fully independent computers that process all incoming inputs, exchange data via a digital bus, and maintain control of all outgoing signals while displaying non-critical and essential aircraft status information to the crew. Each channel has its own Power Supply, Input/Output boards, Central Processor Unit (CPU) and Display Graphics Generator (DG).

Specialized Units

    Customized individual self-contained displays are available as well as Panel Mounted remote generated displays, such as used on the Canadair CL-415 Water Bomber.
