Flight Instruments, Displays

Question 1

Identify where ground speed and true airspeed are displayed

Answer 1

• Ground speed: Top left corner of the ADI
• Ground speed: On the FMS, POS REF page
• True Airspeed: TAS/SAT indicator
• True Airspeed: FMS, Progress page 2

Question 2

Know if the VOR / DME switch on the mode control panel is in the MAN mode, moving the EFIS control panel HSI mode selector from MAP to any position except PLAN, then returning to MAP, will cause the VOR / DME switch to return to AUTO.

Question 3

Recall that stations displayed in green on the HSI map display
represent stations that are either being AUTO tuned or have been MAN (manually) tuned using the VOR/DME control panel.

Question 4

Recall how to display LOC (Localizer) DME

Answer 4

• Place the EFIS control panel in EXP ILS or FULL ILS or APP (as
  installed)
• Read the LOC DME mileage on the RDMI preceded by the
  letter L and reference the ILS DME mileage in the upper left
  corner of the HSI

Question 5

Recall that an ILS frequency can only be manually tuned on the ILS Control Panel.

Question 6

Recall the VNAV Vertical Deviation scale range is +/- 400 feet.

Question 7

Recall the standby ADI has an attitude source that is self-contained

Question 8

Discuss the function of the PLI (Pitch Limit Indicator)

Answer 8

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

Question 9

Recall that flags will be displayed for inoperative flight instruments

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

Question 12

Identify the aircraft heading when looking at various HSI displays.

Answer 12

See LOD for pictures

Question 13

Identify where the wind direction and speed are displayed

Answer 13

• In the bottom left corner of the HSI.

Question 14

Explain what the altitude range “green” arc indicates during climb or descent.

Answer 14

• The “Green Arc” predicts where the aircraft will reach the
  selected MCP altitude and considers ground speed and vertical speed in its calculations.

Question 15

Identify the active waypoint on the MAP and on the FMS MCDU

Answer 15

• Magenta in the MAP mode.
• Line L1 on the active LEGS page.
• Line L1 on the PROGRESS page 1.

Question 16

Explain how the radio altimeter minimums are set and reference where they are displayed

Answer 16

• Set using the rotary switch on the EFIS HSI control panel.
• Displayed on the EFIS HSI control panel.
• Displayed on the top right corner of the ADI

Question 17

Recall how the HSI display modes are selected.

Answer 17

• Use the EFIS HSI control panel.

Question 18

Explain the orientation of the HSI in the PLAN mode.

Answer 18

• The PLAN mode is presented True North up.

Question 19

Recall the various displays associated with each of the different Map switches (ie: NAV AID, ARPT, DATA, WPT, TERR, WXR) on the EFIS control panel.

Answer 19

Terrain (TERR) Display Select switch

Push –

• Displays terrain data in VOR, APP, MAP, and CTR MAP modes
• 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)

Navigation Aid (NAV AID) switch

Push –

• Displays only the high altitude VHF navigation aids when the HSI range is 80nm or greater
• Displays all VHF navigation aids when the HSI range is 40nm or
  less

Airport (ARPT) switch

Push –

• Displays all FMS database airports in the display range

Route Date (RTE DATA) switch –

Push –

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

Waypoint (WPT) switch –

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 20

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

Answer 20

Selects the flight control computer (Left, Center, or Right) used as the
source of commands for the captain’s flight director display

Question 21

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

Answer 21

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)

Question 22

Recall the function of the FMC switch (as installed) on the
instrument source select panel.

Answer 22

Selects an alternate source of FMC information used by the EFIS symbol generators

Question 23

Recall the function of the EFI switch on the instrument source select panel.

Answer 23

Selects an alternate EFIS symbol generator, ILS receiver, and radio altimeter used as the sources of information for the
respective ADI and HSI displays

Question 24

Recall the function of the IRS switch on the instrument source select panel.

Answer 24

Selects an alternate IRS information source for the symbol generators, the VSI, and the RDMI. Information provided by the IRS includes attitude, heading, and vertical speed.

Question 25

Recall the function of the AIR DATA switch on the instrument
source select panel.

Answer 25

Selects an alternate air data computer information source for the respective Mach/Airspeed indicator, primary altimeter, and
vertical speed indicator.
