B748 Flight Instruments Display System

Describe the operation of the EVENT RECORD switch? FCOM 1 - 31.10.8

Records up to 5 EICAS events

When and where is the radio altitude displayed? FCOM 1 - 31.10.18

PFD when the radio altitude is below 2,500ft

When will TCAS RA be inhibited and what is annunciated on left side of the navigation display? FCOM 1 - 31.24.4

When TA/RA is selected on the transponder panel and a GPWS or PWS warning alert occurs, TCAS inhibits RA mode and operates in TA ONLY mode. All aircraft that would have been predicted as a RA are predicted as a TA. When a subsequent GPWS or PWS warning alert occurs while a RA is occurring, the RA is discontinued and becomes a TA. When GPWS or PWS warning alerts are no longer occurring, TCAS returns to TA/RA mode and provides RAs for all appropriate TAs.

When will weather radar transceiver receive power? FCOM 1 - 31.10.62

WXR (weather radar)—

• powers radar transceiver selected on weather radar control panel

• displays in expanded MAP, MAP CTR, VSD, VOR, and APP modes

• displays weather radar information (refer to Chapter 34, Navigation Systems)

• with WXR FAIL displayed on ND, cancels WXR FAIL message

Describe EIU functions input and output? FCOM 1 - 31.20.1

The integrated display system consists of three identical EFIS/EICAS interface units (EIUs) which receive and display airplane systems information. The EIUs supply information to the flight crew on six display units:

• Captain and First Officer primary flight display (PFD)

• Captain and First Officer navigation display (ND)

• engine indication and crew alerting system (EICAS)

• the multifunction display (MFD). The lower display can be used as the

Multifunction Display (MFD), refer to Aircraft General, Chapter 20

What are the normal air data source for captain and first officer display?

Captain - L

F/O - R

What are the features of display unit brightness control knob and what does the inner knob control? FCOM 1 - 31.10.71

1 Outboard (OUTBD) Display Brightness Control

Rotate—adjusts brightness of outboard display.

2 Inboard (INBD) Display Brightness Control (outer)

Rotate—adjusts brightness of inboard display.

3 Inboard (INBD) Display Brightness Control (inner)

Rotate—adjusts weather radar or terrain display brightness on inboard display.

What are the normal and back up power sources for the ISFD? FCOM 1 - 31.20.11

- The main battery bus powers the ISFD. Selecting the battery switch ON activates the ISFD. After 10 seconds, a 90 second initialization sequence begins.

- The ISFD is powered by a dedicated battery/charger system capable of providing power for up to 150 minutes after loss of power to the main battery bus.

Where does the approach data for the ISFD come from? FCOM 1 - 31.20.11

ILS or GLS information is provided by the left approach receiver.

What are the pitot static sources for the ISFD? FCOM 1 - 31.20.11

The ISFD receives pitot and static pressure from auxiliary pitot and alternate static sources.

What are the sources of heading information to the ISFD FCOM 1 - 31.20.11

Heading information is provided by the left ADIRU. In non-polar regions, the ISFD displays magnetic heading. In polar regions, the ISFD displays true heading with TRU displayed on the left side of the compass rose.

What is the purpose of ADM? FCOM 1 - 31.20.12

The pitot static system provides pitot pressure and static pressure to the air data modules (ADMs), integrated standby flight display, and elevator feel computer. The ADMs convert the inputs to digital data for use by the Air Data Computers (ADCs).

Describe center ADC role and switching FCOM 1 - 31.20.14

The center ADC is a standby ADC and may be selected as a replacement using the Center Air Data selector. The center ADC has its own pitot probe and ADMs but receives static pressure and AOA inputs from the same probes as the ADC it replaces and uses the opposite side TAT probe.

Where can static air temperature data be viewed FCOM 1 - 31.20.14

SAT displays on Progress page 2.

What are status messages used for? FCOM 1 - 31.21.1

EICAS status messages indicate equipment faults which affect airplane dispatch capability

What is the implication of a rectangular symbol prefaced EICAS message? FCOM 1 - 31.21.2

A rectangular symbol [] prefaces an alert message that has procedural steps. The rectangular symbol [] also prefaces EICAS alert messages for checklists that have notes or information of which the crew must be made aware.

List the types of EICAS messages that cannot be cancelled? FCOM 1 - 31.21.2

Red EICAS alert messages remain displayed and cannot be canceled by pushing the Cancel/Recall switch.

Communication messages can not be cancelled by pushing the Cancel/Recall switch.

What differentiates Caution Messages from Advisory messages? FCOM 1 - 31.21.3

EICAS caution messages are displayed in amber below the lowest warning message. EICAS advisory messages are displayed in amber below the lowest caution message and are indented one character so they may be distinguished from EICAS caution messages.

How to view multiple pages of EICAS messages and what happens when the last page is reached? FCOM 1 - 31.21.3

Multiple pages of EICAS caution and advisory

messages can be displayed one page at a time by pushing the Cancel/Recall switch. If there are more EICAS warning messages in the list than can be displayed on one page, no page number is displayed and it is not possible to display other pages.

What are the indications when the aircraft is approaching a stall? FCOM 1 - 31.21.8

Warning of an impending stall is provided by left and right stick shakers, which independently vibrate the left and right control columns.

What triggers the EICAS message AIRSPEED LOW to display? FCOM 1 - 31.21.8

The EICAS caution message AIRSPEED LOW is displayed and the box around the current airspeed indication on the PFD is highlighted amber if airspeed is below minimum maneuvering speed.

Describe takeoff configuration warnings and inhibits FCOM 1 - 3|.2|.9
