Q

Explain the function of the DISPLAYS SOURCE selector

A

AUTO:
- DEU 1 drives the CA’s outboard, inboard and upper DU
- DEU2 drives the FO’s outboard, inboard and lower DU
- Provides automatic switching from both DEUs to one DEU in case of a single DEU failure

ALL ON 1 or 2:
- selects either DEU 1 or DEU 2 to drive all 6 displays

A

NORMAL:
- left EFIS control panel controls CA’s displays
- right EFIS control panel controls FO’s displays

BOTH ON 1 or 2:
- both pilot’s displays are set to the selected pilot’s EFIS control panel

Note: when in the NORMAL position, a DISPLAYS CONTROL PANEL annunciation illuminates below the altitude indication showing a failure of the associated EFIS control panel

Q

Describe the alert associated with a DEU failure

A

DISPLAY SOURCE (amber) on the lower left corner of the PFD

Note: if a DEU fails, the remaining DEU automatically supplies data to all six displays. A single DEU failure will continue to supply each pilot with flight instrument information from independent sources. If the displays are automatically or manually switched to a single DEU source, a “DISPLAY SOURCE” annunciation illuminates on both PFDs below the airspeed indicator

  • Selected vertical speed bug (magenta): indicates the speed selected in the MCP vertical speed window with V/S pitch
    mode engaged
  • Vertical speed (white): displays vertical speed when greater than 400 ft/min. The display is located above the vertical
    speed indication when climbing and below when descending
  • TCAS vertical speed tape ( red): tape turns red to indicate vertical speed values to avoid or exit during a TCAS RA. Vertical
    speed pointer is also red if it is within the vertical speed tape range
18
Q

Recall the location and purpose of the PFD approach reference indication

A
  • The approach reference indicator is displayed on the upper left-hand corner of the PFD
  • Displays the selected ILS/IAN identifier or frequency, approach front course, and ILS/DME/FMC distance and source
    annunciation

Note: if the tuned ILS frequencies disagree, the frequency turns amber with an amber horizontal line through it. If the approach courses entered in the MCP disagree, the course turns amber with an amber horizontal line through it

19
Q

  • TCAS vertical speed tape turns red to indicate vertical speed values to avoid or exit during a TCAS RA. The vertical speed
    pointer is red if it is within the vertical speed tape range
20

Displaces beneath the bank pointer to indicate slip or skid:
- fills white at full scale deflection
- turns amber if bank angle is 35 degrees or more
- fills amber if the slip/skid indication is also at full scale deflection

21

- RADIO: selects radio altitude as the minimums reference
- BARO: selects barometric altitude as the minimums reference

Minimums (MINS) selector (middle - slew)
- ROTATE: adjusts the radio or baro minimums altitude

Minimums (MINS) Rreset (RST) Switch (inner - momentary action)

A

True north up

30
Q

Explain the function of the EFIS control panel mode selector

A

Mode selector (outer): selects the desired display
APP:
- displays LOC and GS information in heading-up format
- displays reference ILS receiver, ILS frequency or identification, course and DMW (WX radar and TCAS are not displayed
in center APP mode)

VOR:
- displays VOR navigation information in heading-up format
- displays reference VOR receiver, VOR frequency or identification, course, DME and TO/FROM information (WX radar
and TCAS are not displayed in center VOR mode)

MAP:
- displays FMC generated route and MPA information, airplane position, heading and track, in a track-up format
- displays waypoints, including the active waypoint, within the selected range
- displays VNAV path deviation

PLN:
- displays a non-moving, true north up, route depiction
- the airplane symbol represents actual airplane position and orientation
- allows route step-through using the CDU LEGS page (WX radar and TCAS are not displayed)

Center (CTR) switch (inner):
PUSH
- displays full compass rose (center) for APP, VOR & MAP modes
- subsequent pushes alternate between center with VSD, expanded, and center without VSD

31
Q

Explain how the map scale differs when in the center map mode

A

The A/C symbol is in the center of the ND. The full compass rose is displayed for APP, VOR, and MAP modes. Subsequent pushes of the CTR switch alternates between map, center map, and center map with VSD

32
Q

Recall what is displayed with each of the EFIS control panel MAP switches

A

WXR (weather radar):
- energizes weather radar transmitter and displays weather radar returns in MAP, center MAP, VOR, and APP modes

STA (station):
- displays FMC data base navigation aids

WPR (waypoint):
- displays the waypoints in the FMC data base which are not in the flight plan route if the selected range is 40 nm or less

ARPT (airport):
- displays all airports which are stored in the FMC data base within the viewable map area

DATA:
- displays altitude constraints, and ETA for each active route waypoint

POS (position):
- displays IRS positions, GPS positions, and VOR bearing vectors extended from the nose of the airplane symbol to manually tuned stations

TERR (terrain):
- displays GPWS generated terrain data in MAP, center MAP, VOR and APP modes

33

A

Boxed amber alerts replace failed flight instruments

35
Q

Recall what indications will be displayed to indicate excessive glide slope and localized deviation on the PFD

A

At low radio altitudes (with AP engaged), the appropriate scale turns amber and the pointer flashes to indicate excessive glide slope/glide path or LOC/FAC deviation

36
Q

Recall the location and purpose of the PFD scale ID annunciation

A
  • Displayed above the left corner of ADI
  • Indicates the source of displayed deviation for each scale
37
Q

Describe the PFD navigation performance scale (NPS) indications

A

NPS deviation scale:
- lateral NPS deviation scale represents current FMC lateral RNP
- vertical NPS deviation scale represents current FMC vertical RNP

Anticipation Cues
- unfilled white diamond symbol is displayed if valid approach course deviation information is being received

Note: anticipation cues are displayed to indicate underlying approach roll and pitch information (I.e. LOC and G/S or FAC and G/P) while the NPS pointers display current VNAV and LNAV paths relative to the airplane

NPS pointer:
- pointer is filled magenta when it is not parked at deflection limit
- pointer is unfilled outline when at deflection limit
- indicates lateral/vertical paths relative to the airplane

Note: will flash for 10 seconds if pointer is within ANP bar limits for 5 continuous seconds

Actual Navigation Performance (ANP) bars
- originate from outer scale and expand inward as a function of increasing ANP (indicates amount of error in the system)

Note:
- bars would touch at center of scale if ANP equals RNP
- bars turn from white to amber if current deviation is within the ANP bar limits for 10 continuous seconds

38
Q

Recall the location and method of displaying the vertical situation display

A

The VSD is accessed by pressing the EFIS control panel center (CTR) switch twice and is displayed on the ND. The VSD represents a profile view of the airplane and the environment along the current track. Information shown within the cyan dashed lines (enroute corridor/swath) on the ND is shown in profile on the VSD.

39
Q

Recall the purpose of the Vertical Situation Display (VSD) terrain profile line

A

Represents the highest terrain within the enroute swath
- highest points of the terrain below and ahead of the airplane
- terrain is depicted so the true altitude separation between the airplane and terrain is shown
- VSD terrain uses the same color coding that is used to depict EGPWS terrain on the lateral map

40
Q

Recall the function of the VOR switch on the EFIS control panel

A

Displays VOR information on all navigation modes except PLAN
- VOR: displays the selected VOR bearing pointer, frequency, or identification and DME
