Q

What side are the controls for the EADI on?

A

on the left

17
Q

What side are the EHSI controls on?

A

right side

18
Q

The five (5) map buttons on the lower right of the panel determines what?

A

the map mode of the EHSI.

19
Q

The BITE information is accessed through what?

A

the right or left control display unit (CDU).

20
Q

In-flight faults occur whenever:

A

the aircraft is airborne

21
Q

Current status is used to what?

A

test the various components of the EFIS and related interfaces

22
Q

During a “processor circuitry failure”, a message will be generated and will cause a:

A

“SG FAIL” and an “X” will be displayed on the EADI/EHSI.

23
Q

2nd Generation EFIS: The new EFIS allowed for what?

A

better flight deck management, improved reliability and maintainability.

24
Q

What are the main processing units for the IDS?

A

Three electronic interface units (EIUs) ensuring redundancy

25
Q

Since IDS is an integrated system, it provides what?

A

greater flexibility in the event of display failures

26
Q

Boeing 777 introduced a system known as:

A

AIMS - Aircraft Information Management System

27
Q

Which data bus is the backbone data transfer system for AIMS?

A

ARINC 629

28
Q

What are the 3 main benefits of AIMS?

A

Enhances reliability
Improves redundancy
Creates substantial weight savings

29
Q

Which system can detect a fault and reconfigure the system for uninterrupted operations?

A

AIMS

30
Q

The AIMS has the ability to transfer data in a variety of what?

A

communication formats

31
Q

What are considered to be critical formats?

A

Primary Flight Displays (PFDs) and the Engine Indicating and Crew Alerting Systems (EICAS)

32
Q

What are considered to be essential formats?

A

Navigational Displays (ND) and the Multipurpose Flight Displays (MFD)

33
Q

The B-787 Dreamliner calls their system what?

A

The Common Core Systems (CCS)

34
Q

What is the first transport category aircraft with HUDs as standard equipment?

A

B-787 Dreamliner

35
Q

The Common Core System (CCS) consists of three major elements:

A
  1. Processing circuitry to execute applications software.
  2. The Common Data Network (CD) that provides communications between all segments on the CCS.
  3. Remote data concentrators that provide gateways to analog, discrete and ARINE 429 based equipment.
36
Q

The RDCs provide what?

A

a digital gateway for analog, discrete or digital (ARONC 429) signals

37
Q

The raster signal provides what?

A

the background video such as the attitude ball and weather images
