Flight Instruments Flashcards
How many primary pitot probes and what are their components?
2 primary pitot probes (left and right) each one has 1 pitot source and 2 static sources
The alternate static system consists of:
Two static ports and one pitot probe
The _____ provides attitude and heading information to the EFIS
AHRS
If AHRS data is lost, the opposite side AHRS signal and display are selected by using:
The ATTD HDG selector on the Source Select Panel
When should AHRS initialization take place?
Automatically when the battery master is turned on.
What are the components of the EFIS system?
- Display Reversionary Panels (DCPs)
- Electronic Flight Displays (EFDs)
- Source Selector Panel
- Display control panels (DCPs)
If I wan’t to transfer MFD information to the PFD, what should i do?
Transferring MFD information to the PFD is NOT possible.
The panel used to transfer the PFD display to the adjacent MFD is:
the Display Reversionary Panel (DRP)
The Source select panel on the center console is used to:
Select alternate sources for critical system display
What indicates the aircraft drift angle in relationship to a programmed FMS route?
The green doughnut… (drift angle pointer)
Can bearing angle pointers be displayed on both the MFD and the PFD?
YUP
What does a YELLOW “PIT” box by the attitude indicator on the PFD tell you?
The pitch difference is >4 degrees before glide slope capture and >3 degrees after between the two AHRS
Can the weather overlay be presented in all MFD modes?
No, only on:
- NAV SECTOR
- FMS MAP
- TCAS
The FDR records how far back?
The last 25 hours
What is the difference between PFD and standby air data information?
Standby is raw data
If shooting an ILS approach, with only the standby instrument, what are some considerations?
Can only use NAV 1 with it tuned into a valid ILS frequency.
What is the the purpose of the IAP?
The integrated avionics processing system compares the R ADC and L ADC together and decides whether their matching or not.
What is a situation we would take off in the DG mode instead of MAG mode?
If we were in an area of known magnetic anomaly, we would set it to DG mode and use SLEW to align it with the runway.
What is the purpose of the remote compensating unit (RCU)?
The RCUs will get rid of turning errors: UNOS and ANDs
What is the MFD Page that we should to use while in flight?
FMS map, with terrain, and TCAS overplayed over that
What will happen to EFIS when passing through 31,600’?
Airspeed will be shown in MACH, 1/2 rate of turn will be activated.
How can you transition through MFD Navigation displays?
The Display Control Panel
How do you display traffic on the FMS map display?
Ensure the scale is 40nm or below on the FMS map display and then select traffic
Where is the top of the low speed cue?
1.06 Vs in landing gear configuration
Low-Speed awareness cue is located where? And what is it indicated as?
It’s a green line that indicates 25% above stick shaker speed
When will indicated MACH be displayed above the airspeed tape?
When the aircraft accelerates through .45M and when passing through 31,600’
When is MACH removed from the Airspeed indicator?
When slowing below .40M
If a “EFIS COMP MON” is displayed, where do you look to get more information?
The PFD
Where does the Integrated Standby Instrument Receive it’s power from?
DC BATT BUS
S3 ports are connected to the ________ and provide static pressure to:
- The ISI
2. Cabin Pressure Controller
ADC purpose
Convert pitot static info to electronic signals to produce airspeed and altitude data
AHC
Attitude and heading computer
AHRS consists of
2 AHCs
2 Flux detectors
2 Remote compensator units
A compass control panel
Location of flux detectors
Wing tips.
When is DG mode selected.
When operating around magnetic disturbances
When does AHRS initialization take place?
When electrical power is applied to the aircraft
What do comparators do?
Continually compares its onside AHRS data with the offside AHRS data
When a comparator error is detected, what will happen?
Flashing amber data message e.g “HDG” “ROLL” “PIT” “IAS” “ALT” “RA” “FD” “LOC” “GS”
Amber HDG on PFD is a ________.
Comparator Error
ISI is powered by the:
Battery Bus
