FOR SIMULATION USE ONLY ā NOT A TRAINING AID
INTEGRATED AVIONICS SYSTEM
Each cockpit provides a full complement of flight instrumentation and engine
controls and displays, based around three Multifunction Displays (MFDs), and a
Head up Display (HUD).
The HUD is in the front cockpit and provides a flight-path-based attitude display
(i.e., attitude, heading, and navigation information). Head Up in Mission (HUM) Circuit
Card Assembly (CCA) is responsible for the HUD displays.
Any one of the MFDs in either cockpit can be used as the Primary Flight Display
(PFD) to support basic pilot training. The three MFDs are fully configurable to suit
specific training requirements.
Instrumentation for primary air data (altimeter, airspeed, and vertical velocity
indicator) is also presented on the HUD and MFDs, while engine instrumentation is
also available on the MFDs.
A camera system is provided with the HUD to allow HUD symbology to be
superimposed over the cockpit view in the rear cockpit. Display of vertical G
acceleration, gage, and indexer presentation of angle of attack, are also provided on
the HUD. Warning, caution, advisories, and status are placed on the Engine
Indication and Crew Alerting System (EICAS) page.
The Navigation (NAV) data Display provides access to the navigation capabilities of
the on-board navigation equipment (FMS, IRS, VOR/ILS, and DME).
The stick and throttle grips have Hands On Throttle and Stick (HOTAS) switches for
control of simulated weapons delivery and frequently used in-flight functions.
Primary air data information is provided through dual integrated avionics
computers (IACs). The dual IACs (IAC 1 and IAC 2) form the core of the integrated
avionics system, integrating the various components of the system as well as
providing backup capability.
The information from the IACs is presented by three MFDs in each cockpit.
PFD/EICAS/NAV (PEN) CCA is responsible for the symbol generation for the display
on the MFDs.
The IACs receive primary data input from the inertial reference system (IRS), air
data computer (ADC), global positioning system (GPS), VOR/ILS, distance measuring
equipment (DME), traffic alert and collision avoidance system (TCAS), Mode S
transponder, radar altimeter system, VHF radio system, UHF radio system, angle of
attack (AOA) computer, and engine data manager (EDM).
