Flight Instruments, Displays

Question 1

(756) Identify where ground speed and true airspeed are displayed

Answer 1

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

Question 2

(756) Recall what the stations displayed in green on the HSI map display represent

Answer 2

Stations that are either being AUTO tuned or have been MAN (manually) tuned using the VOR/DME control panel.

Question 3

(756) Recall how to display LOC (Localizer) DME.

Answer 3

 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 4

(756) Recall the VNAV Vertical Deviation scale range is

Answer 4

+/- 400 feet.

Question 5

(756) Recall the standby ADI has an attitude source that is

Answer 5

selfcontained.

Question 6

(ALL) Discuss the function of the PLI (Pitch Limit Indicator)

Answer 6

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

Question 7

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

Answer 7

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

Question 8

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

Answer 8

The left side of the ADI

- 10 knot scale

Question 9

(756) Identify the aircraft heading when looking at various HSI displays.

Answer 9

Reference the green “HDG” or “TRK” indications at the top of the HSI

Question 10

(756) Identify where the wind direction and speed are displayed

Answer 10

In the bottom left corner of the HSI.

Question 11

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

Answer 11

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

Question 12

(756) Identify the active waypoint on the MAP and on the FMS MCDU

Answer 12

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

Question 13

(756) Explain how the radio altimeter minimums are set and reference where they are displayed.

Answer 13

 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 14

(756) Recall how the HSI display modes are selected.

Answer 14

Use the EFIS HSI control panel.

Question 15

(756) Explain the orientation of the HSI in the PLAN mode.

Answer 15

The PLAN mode is presented True North up.

Question 16

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

Answer 16

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

Question 17

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

Answer 17

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 18

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

Answer 18

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

Question 19

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

Answer 19

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 20

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

Answer 20

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 21

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

Answer 21

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