Recall the standby ADI has an attitude source that is ______________

Answer 7

self-contained.

Question 8

Discuss the function of the PLI (Pitch Limit Indicator)

Answer 8

Pitch Limit Indicator

• Indicates pitch limit (stick shaker activation point for the existing flight conditions).

Recall that ____________ will be displayed for inoperative flight instruments

Answer 9

flags

Question 10

Recall what ADI indications are displayed during excessive glideslope or localizer deviation.

Answer 10

• The deviation scale turns from white to amber and the pointer flashes.

Question 11

Recall on the ADI where references for F/ S (fast or slow) airspeed are displayed.

Answer 11

• The left side of the ADI

• Arms terrain data in CTR VOR, CTR APP, and PLN modes
• Deselects the weather radar display regardless of the mode selector position
• A second push deselects the terrain display.

Weather Radar (WXR) switch
Push –
• Displays weather radar information (refer to Chapter 11, Flight
Management, Navigation).

Question 19

Navigation Aid (NAV AID) switch

Answer 19

Push –

Answer 20

Push –

• Displays all FMS database airports in the display range.

Question 21

Route Date (RTE DATA) switch –

Answer 21

Push –

• Displays the estimated time of arrival and any altitude constraint for each waypoint in the displayed flight path

Question 22

Waypoint (WPT) switch –

Answer 22

Push –
• Displays all waypoints when the HSI range is 40nm or less
• Waypoints associated with NDBs are displayed at any selected range as long as they are within 80nm of the airplane.

Question 23

Recall the function of the FLT DIR switch on the INSTR SOURCE SEL (Instrument Source Select) panel

Answer 23

Flight Director (FLT DIR) Source selector Selects the flight control computer (Left, Center, or Right) used as the source of commands for the captain’s flight director display

Question 24

Recall the function of the NAV selector (as installed) on the INSTR SOURCE SEL panel

Answer 24

Navigation (NAV) Source selector Selects an alternate FMC information source used by EFIS symbol
generators and the flight control computers (FCCs). The CDU position is used for operation of the Alternate Navigation System (refer to Chapter 11, Flight Management, Navigation).
