Flight Instruments & Displays Flashcards
Data sources for primary flight instruments?
ADCs
ADCs receive input from what 3 sources?
- Pitot/Static
- AOA
- TAT Probe
CA vs FO (ADC Sources)?
- CA = Left ADC
- FO = Right ADC
Only backup is reversion via ISS ADC button
If a failure of all AC PWR occurs, which flight instruments will operate when on BATT PWR?
CENTER SEVEN:
- MASTER WARN/CAUTION
- Standby Instruments
- CA RDMI
- SEI
<em>GEAR/FLAPS must be extended within 30mins</em>
How are clocks powered?
HOT BATT BUS*
<em>*main DC BUS PWR </em><em>req’d</em><em> for </em><em>upper</em><em> display</em>
EFIS instruments consist of?
(E)ADI + (E)HSI
CA vs FO (EFIS SG sources)?
CA EFIS = L SG FO EFIS = R SG * C SG available to both as a backup
CA vs FO (EFIS IRU sources)?
HDMI?
- 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
SG (ILS + RA sources)?
L SG = L ILS + L RA R SG = R ILS + R RA C SG = C ILS + C RA
ATT DISAGREE
3 degrees of pitch or roll difference between CA/FO
Rising Runway visible at?
2500’ RA
RA Display visible at?
2500’ RA
DH alert resets when?
- Press RESET switch - RA increases to DH +75 (Go-Around) - RA decreases to 0 (Land)
EFIS Airspeed Tape Indicators?
- 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)
PLI displayed?
Flaps out of UP
Mach speed displays above what speed?
M .40
STBY ATT (ILS source)?
C ILS
STBY ATT (PWR source)?
STBY DC BUS
STBY IAS (PWR source)?
None.
Directly connected to CA’s pitot/static.
STBY ALTIMETER (PWR source)?
None.
Directly connected to alternate static ports.
When does FDR operate?
GND - After either engine start FLT - All the time
RDMI (IRU Sources)?
- CA RDMI = R IRU
- FO RDMI = L IRU
C IRU provides alternate heading signals.
Will (E)HSI and (E)ADI displays work without respective SG power?
NO. Displays are blank.
Primary purpose of FCC?
Provides data relating primarily to automatic flight for EFIS/FD
Source selector switches control what functionality?
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
When will R FMC be selected as MASTER without manually selecting via NAV switch?
- R A/P in command
- All A/P and the L FD are OFF and only R FD is ON
EFI Switch controls?
- SG data to respective EFIS
- backup for either CA or FO is C SG
- Both CA + FO are using C SG (EICAS MSG)
ISS: IRS Switch controls?
Selects respective CA or FO to C IRU in event of failure.
CDU (ALTN NAV Mode) Available FMC Information?
- PROG PG1
- LEGS
- all waypoints must be entered as LAT/LONG*
- active WPT is magnetic, subsequent are true as IRU only knows PPOS*
DUAL FMC FAIL available NAV equip?
- Autothrottles still active
- NO LNAV
- NO VNAV
- HDG bug must be used
SRC Selector to CDU
LT OVRD Switch turns on?
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
VIDEO ON light?
Safety Demo playing. Do not interrupt.
<em>not all A/C are equipped however</em>
