1. INTRODUCTION
The indicating and recording systems consist of components that provide visual and aural
indications of system operation, aircraft configurations and to record aircraft information.
Data from the aircraft systems and from each engine is received and processed by two data
concentrator units (DCU’s) located in the avionics compartment. The DCU’s provide
information to the engine indication and crew alerting system (EICAS). Master warning and
caution lights on the glareshield enhance the indication system. Audio signals are
generated within the DCUs and are heard through the flight deck speakers.

The DCU’s also provide interface with the flight data recorder system (FDR), the lamp driver
unit (LDU) and the maintenance diagnostic computer (MDC) via the integrated avionic
processor system (IAPS).
