Flight Instruments & Displays

Question 1

Data sources for primary flight instruments?

Answer 1

ADCs

Question 2

ADCs receive input from what 3 sources?

Answer 2

• Pitot/Static
• AOA
• TAT Probe

Question 3

CA vs FO (ADC Sources)?

Answer 3

• CA = Left ADC
• FO = Right ADC

Only backup is reversion via ISS ADC button

Question 4

If a failure of all AC PWR occurs, which flight instruments will operate when on BATT PWR?

Answer 4

CENTER SEVEN:

• MASTER WARN/CAUTION
• Standby Instruments
• CA RDMI
• SEI

_{<em>GEAR/FLAPS must be extended within 30mins</em>}

Question 5

How are clocks powered?

Answer 5

HOT BATT BUS*

_{<em>*main DC BUS PWR </em><em>req’d</em><em> for </em><em>upper</em><em> display</em>}

Question 6

EFIS instruments consist of?

Answer 6

(E)ADI + (E)HSI

Question 7

CA vs FO (EFIS SG sources)?

Answer 7

CA EFIS = L SG FO EFIS = R SG * C SG available to both as a backup

Question 8

CA vs FO (EFIS IRU sources)?

HDMI?

Answer 8

• CA (E)HSI + (E)ADI = L IRU
• FO (E)HSI + (E)ADI = R IRU
• C IRU = SPARE via respective ISS
• CA RDMI = R IRU
• FO RDMI = L IRU

Question 9

SG (ILS + RA sources)?

Answer 9

L SG = L ILS + L RA R SG = R ILS + R RA C SG = C ILS + C RA

Question 10

ATT DISAGREE

Answer 10

3 degrees of pitch or roll difference between CA/FO

Question 11

Rising Runway visible at?

Answer 11

2500’ RA

Question 12

RA Display visible at?

Answer 12

2500’ RA

Question 13

DH alert resets when?

Answer 13

• Press RESET switch - RA increases to DH +75 (Go-Around) - RA decreases to 0 (Land)

Question 14

EFIS Airspeed Tape Indicators?

Answer 14

• F
  
  • Maneuvering speed for existing flaps
• Magenta Horizontal Lines
  
  • MCP selected speed
• Yellow Box
  
  • MIN Maneuvering Speed (1.3g)
• Red Ants
  
  • MIN Operating Speed (Shaker Activation)

Question 15

PLI displayed?

Answer 15

Flaps out of UP

Question 16

Mach speed displays above what speed?

Answer 16

M .40

Question 17

STBY ATT (ILS source)?

Answer 17

C ILS

Question 18

STBY ATT (PWR source)?

Answer 18

STBY DC BUS

Question 19

STBY IAS (PWR source)?

Answer 19

None.

Directly connected to CA’s pitot/static.

Question 20

STBY ALTIMETER (PWR source)?

Answer 20

None.

Directly connected to alternate static ports.

Question 21

When does FDR operate?

Answer 21

GND - After either engine start FLT - All the time

Question 22

RDMI (IRU Sources)?

Answer 22

• CA RDMI = R IRU
• FO RDMI = L IRU

C IRU provides alternate heading signals.

Question 23

Will (E)HSI and (E)ADI displays work without respective SG power?

Answer 23

NO. Displays are blank.

Question 24

Primary purpose of FCC?

Answer 24

Provides data relating primarily to automatic flight for EFIS/FD

Question 25

Source selector switches control what functionality?

Answer 25

DISPLAY SOURCES ONLY (ie, CA): * FLT DIR: Flight Control Computer * FMC: R FMC (CDU for DUAL FMC FAIL) * EFI: C SG (C ILS + C RA) * IRS: C IRS * ADC: R ADC

Question 26

When will R FMC be selected as MASTER without manually selecting via NAV switch?

Answer 26

* R A/P in command * All A/P and the L FD are OFF and only R FD is ON

Question 27

EFI Switch controls?

Answer 27

* SG data to respective EFIS * backup for either CA or FO is C SG * Both CA + FO are using C SG (EICAS MSG)

Question 28

ISS: IRS Switch controls?

Answer 28

Selects respective CA or FO to C IRU in event of failure.

Question 29

CDU (ALTN NAV Mode) Available FMC Information?

Answer 29

- PROG PG1 - LEGS * all waypoints must be entered as LAT/LONG* * active WPT is magnetic, subsequent are true as IRU only knows PPOS*

Question 30

DUAL FMC FAIL available NAV equip?

Answer 30

* Autothrottles still active * NO LNAV * NO VNAV * HDG bug must be used ## Footnote *SRC Selector to CDU*

Question 31

LT OVRD Switch turns on?

Answer 31

Overrides normal control and illumes the following at max brightness: * FWD Flood Lights * Illumed Indicator Lights * Glareshield Flood Lights * Aisle Stand Flood Lights * Dome Lights

Question 32

VIDEO ON light?

Answer 32

Safety Demo playing. Do not interrupt. ^{not all A/C are equipped however}
