|Explain the function of the DISPLAYS SOURCE selector.||
AUTO: - DEU 1 controls the Captain's
outboard, Captain's inboard and
upper display units. - DEU 2 controls the First Officer's outboard, First Officer's inboard,
and Lower Display units. - When a DEU fails, the other DEU controls all display units.
ALL ON 1 or 2: (Used on the ground for maintenance purposes) - Manually switches all display units to a single DEU.
|Explain the function of the DISPLAYS CONTROL PANEL Select Switch.||
NORMAL: - Left EFIS control panel controls Capt's displays. - Right EFIS control panel controls FO's displays.
BOTH ON 1 or 2: - Manually switches control of displays to a single 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.
|Describe the alert associated with a single DEU failure.||
DSPLY 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 "DSPLY SOURCE" annunciation illuminates on both PFDs below the Airspeed Indicator.
|Explain what the PLI indicates.||
Indicates pitch limit (stick shaker activation for existing flight conditions).
|Locate on the PFD the MCP commands for altitude, airspeed, heading and V/S and their respective colors.||
MCP commands are displayed in magenta on the top of the Altitude and Airspeed tapes, on the respective Compass and the Vertical Speed display.
|Explain the meaning of the red and black max speed bar on the airspeed tape.||
Bottom of the bar indicates the maximum speed as limited by the lowest of the following:

Tip of green arrow indicates predicted airspeed in the next 10 seconds based on the current airspeed and acceleration or deceleration.
|Explain what is indicated by the Maximum Maneuver Speed bar (amber) when flaps are not up.||
When flaps are not up, bottom of the bar indicates flap limit placard speed for the next normal flap setting. The display logic is based on a normal flap setting sequence of 1, 5, 15, or 30. The bar is removed when the flap lever is moved to the landing flap selected on the APPROACH REF page or when the flap lever is moved to flaps 30 or 40.
|Explain what is indicated by the Maximum Maneuver Speed bar (amber) with the flaps up.||
Bottom of the bar indicates the airspeed that provides a 0.3g maneuver margin to high speed buffet. May be displayed at high altitude with flaps up, at relatively high gross weights.
|Explain the meaning of the Minimum Maneuver Speed bar (amber) with the flaps extended.||
Top of bar indicates minimum maneuver speed.

|Recall the location and purpose of the PFD Approach Reference indication.||
- 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.
|Explain the indications of a Resolution Advisory (RA) and where they are displayed.||
- Aural directions such as "CLIMB, CLIMB" or "DESCEND, DESCEND". - Intruder aircraft symbol turns red, displayed on the ND in MAP, center
MAP, VOR, or APP modes. - Avoidance maneuver area displayed in red on PFD. - TCAS Vertical Speed Tape turns red to indicate vertical speed values
to avoid or exit during a TCAS resolution advisory. Vertical speed pointer is red if it is within the vertical speed tape range.
|Describe the slip/skid indicator.||
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.
|Locate actual aircraft heading on the PFD and ND.||
PFD - actual aircraft heading is under the white (inverted triangle)
current heading pointer on the compass rose.

TCAS Traffic Symbols - Indicates position of traffic targets. Displayed in MAP, center MAP, VOR and APP modes with TFC selected on the EFIS control panel.
Red Square - TCAS Resolution Advisory (RA).
Amber Circle - TCAS Traffic Advisory (TA).
White Diamond - TCAS Proximate traffic.
Arrow - Traffic climbing or descending at a rate greater than or equal to 500 fpm.
TRAFFIC - Displayed on the ND whenever a TCAS RA or TA is active, whether or not TFC is selected on the EFIS
OFFSCALE - Displayed whenever RA or TA traffic is outside ND range.
|Explain what the Altitude Range Arc indicates during a climb or descent.||
Based on vertical speed and groundspeed, indicates the approximate map position where the MCP altitude will be reached.
|Show where the Active Waypoint/ETA/Distance-To-Go are displayed on the ND (Navigation Display).||
The Active Waypoint/ETA/Distance-To-Go are displayed in the MAP and PLAN modes on the top right corner of the ND.
|Explain how approach minimums are set on the EFIS Control Panel.||

|Describe the PFD flags displayed for inoperative flight instruments.||
Boxed amber alerts replace failed flight instrument.
|Recall what indications will be displayed to indicate excessive glide slope and localizer deviation on the PFD.||
At low radio altitudes (with autopilot engaged), the appropriate scale turns amber and the pointer flashes to indicate excessive glide slope or localizer deviation.
|Recall the location and purpose of the PFD Scale ID Annunciation.||
- displayed above the left corner of ADI. - indicates the source of displayed deviation
for each scale.
|Recall the PFD Navigation Performance Scales (NPS) Indications.||
(2) NPS Deviation Scale - lateral NPS deviation scale represents current FMC lateral RNP. - vertical NPS deviation scale represents current FMC vertical RNP.

received while corresponding NPS deviation scale and pointer are
displayed. - unfilled white diamond symbol.
(4) NPS Pointer - filled magenta pointer symbol when it is not parked at deflection
limit. - unfilled pointer symbol outline when at deflection limit. - indicates lateral/vertical paths relative to the airplane. - will flash for 10 seconds if deviation is within ANP bar limits for 10
(5) Actual Navigation Performance (ANP) Bars - originate from outer scale and expand inward as a function of
increasing ANP relative to RNP. - will just touch at center of scale when ANP equals RNP. - turn from white to amber if current deviation is within the ANP bar
limits for 10 continuous seconds.
|Recall the location and method of displaying the Vertical Situation Display.||
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 its 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.
|Recall the purpose of the Vertical Situation display (VSD) Terrain Profile Line.||
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
