10. Flight Instruments Flashcards
Recall the functions of the six Display Units (1 thru 6)
A consistent set of colors is used to display data on the DUs as follows:
- Red - warning, flight envelope and system limits
- Amber - cautions and abnormal sources
- Brown - earth
- White - scales and associated figures
- Green - engaged modes
- Blue - sky
- Cyan - advisory or status
- Magenta - ILS deviation pointer and flight bars
Recall the function of the EIS (Electronic Instrument System) Control Panels
The ECPs contain various switches for pilot selection of flight and navigation data for display on the six DUs. Selectable options include MAP, PLAN, APPROACH, VOR and TCAS information
VOR/ADF Switches - Push – Controls bearing pointer display on ND
TCAS Switch - Push – Selects dedicated TCAS display on ND
VOR Switch - Push – Selects VOR display on ND
MAP Switch - Push – Selects MAP display on ND
PLAN Switch - Push – Selects PLAN mode display on ND
TRFC Switch - Push – Selects fulltime TCAS display on ND
APPR Switch - Push – Selects APPROACH mode display on ND
DATA Switch - Push – Displays waypoint data (identifier, crosstrack deviation, etc) on ND
WPT Switch - Push – Displays non-flight plan waypoints on ND
ARPT Switch - Push – Displays non-flight plan airports on ND
VOR/NDB Switch - Push – Displays non-tuned stations on ND
INCR/DECR Switch - Push – Controls MAP range on ND
Recall the function of the Minimums knob on the EIS (Electronic Instrument System) Control panel
RA – Sets RA bug on PFD altitude tape by rotating inner collar
BARO – Sets BARO bug on PFD altitude tape by rotating the inner collar
PUSH – Resets PFD DH alert and silences the aural warning
Recall the function of the BAROSET knob on the EIS (Electronic Instrument System) Control pane
QFE/QNH – Selects QFE or QNH for PFD display by rotating inner knob (QFE is disabled and unavailable)
PULL – Selects Standard baroset (29.92 or 1013) for PFD display
**Note: BAROSET values are changed from inches of mercury to hectopascals by use of the IN/HP button
Recall the function of the two aircraft Versatile Integrated Avionics units (VIAs)
Two VIAs provide the following functions: data display, flight management computing, central aural warning, master warning/caution light activation, and flight data acquisition
Normally VIA-1 provides data for the DUs 1 – 3 and VIA-2 provides data for the DUs 4 - 6
In case of failure, either VIA unit will automatically provide data for all DUs
Recall the function of the System Display Control Panel (SDCP)
The SDCP, located on the center pedestal, allows selection of system synoptics, and adjustment of DU brightness
System Cues - Selects applicable system for SD display
ND Switch – With 1 or more DUs inop, causes the existing SD to become an ND
CONSEQ/STATUS/ MISC Switches - Displays respective page on SD
**Note: Individual DUs can be turned off by rotating the respective BRT knob fully counterclockwise through a detent. However, turning all six BRT knobs fully counterclockwise will cause all six DUs to default to full brightness

Recall features of the PFDs
Localizer Pointer & Scale
Localizer deviation scale in view after ILS is tuned. Pointer in view indicates valid data is received–turns amber and flashes to indicate excessive localizer deviation

Cyan = TRU
Recall features of the PFDs
Heading Bug
Outlined when preselected
Filled when selected
Recall the airspeed and altitude/vertical speed display features of the PFDs
Airspeed Trend, Airspeed Bug, Speed Bugs, Airspeed, & Flap/Slat
Airspeed Trend
Green column – end of column is the airspeed to be achieved in 10 seconds
Airspeed Bug
White solid – selected airspeed
White outline – preselected airspeed
Solid magenta circle – FMS commanded speed
Open magenta circle – FMS speed not selected
Speed Bugs
V1, VR, V2, FR, GR, SE, FE & GE bugs are on outside of tape
Airspeed
Box and digits red – A/S below Vss or above Vmo/Mmo
Box and digits amber – A/S below Vmin or above Vmax
Flap/Slat
White – Displays selected flap position (arrow, if shown, indicates flap movement)
Amber and boxed to indicate disagreement
Recall the airspeed and altitude/vertical speed display features of the PFDs
Altitude Bug, Altitude Tape, Vertical Speed, Minimum Bug, Selected Minimum, & Baroset
Altitude Bug
White Solid – Selected altitude
White outline – Preselected altitude
Solid magenta circle – FMS altitude constraint; FMS engaged
Open magenta circle – Crew has intervened in an FMS profile OR the FMS altitude is beyond that set in the FCP
Altitude Tape
Turns amber and flashes to correspond with CAWS altitude advisory alerts

Recall the function of the Inertial Reference System (IRS) control panel
Flashing NAV OFF Light
During alignment, ADIRU does not receive present position initialization within 5 to 10 minutes of turn on
Present position entry fails the comparison test with either the stored or calculated present position
NAV OFF Light
ADIRU is off
ADIRU is in align mode
ADIRU failure
Mode Selector
OFF - Turns ADIRU off
NAV - Normal position
The inertial reference function of the ADIRU provides air data and inertial reference information to the PFDs and NDs
ADIRU-1 is normally powered by the EMER AC bus and backed up by the aircraft battery
An independent back-up battery will provide power to ADIRU-2 for a minimum of 30 minutes if normal power is lost (retains heading, attitude and position)
**Note: Upon throttle advancement for takeoff, FMS position will be updated to the runway threshold
**Note: Normal alignment takes about 10 minutes. A fast (3-minute) realignment can be initiated by cycling the selector from NAV to OFF to NAV w/in 5 seconds
Recall the location of the Standby Magnetic Compass and the light switch.
The standby magnetic compass is mounted above and behind the F/O and provides a heading reference in relation to magnetic north
The Captain and First Officer’s viewing mirrors, mounted on the glareshield, permit viewing the standby compass
The light switch is in the Lower right hand corner of overhead panel
