Flight Instruments Flashcards
Recall the function of the EIS Control Panels (Electronic Instrument System)
The ECPs contain various switches for pilot selection of flight and navigation data for display
on the PFDs and NDs. Selectable options include MAP, PLAN, APPROACH, VOR and
TCAS information
VOR/ADF Switches Push – Controls bearing pointer display on ND ARPT Switch Push – Displays non-flight plan airports 5,000’+ on ND INCR/DECR Switch Push – Controls MAP range on ND VOR/NDB Switch Push – Displays nontuned stations on ND PLAN Switch Push – Selects PLAN mode display on ND WPT Switch Push – Displays non-flight plan waypoints on ND DATA Switch Push – Displays waypoint data (identifier, crosstrack deviation, etc) on ND APPR Switch Push – Selects APPROACH mode display on ND TRFC Switch Push – Selects fulltime TCAS display on ND MAP Switch Push – Selects MAP display on ND VOR Switch Push – Selects VOR display on ND TCAS Switch Push – Selects dedicated TCAS display on ND
Recall the function of the Minimums knob on the EIS Control panel (RA, BARO, PUSH)
MINIMUMS
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 Control panel (QFE/QNH, PULL)
BAROSET
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
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). Recall what the ND switch does.
The SDCP, located on the center pedestal, allows selection of system synoptics, and
adjustment of DU brightness
ND Switch
Push – With 1 or
more DUs inop,
causes the existing
SD to become an ND
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
The PFDs symbology maintains the basic “T” configuration with ATTITUDE in the
center, AIRSPEED on the left, ALTITUDE and VERTICAL SPEED on the right,
and DIRECTION of FLIGHT on the bottom
Recall the function of the Integrated Standby Instrument System
ALIGN Button Push - Resets attitude display. Airplane should be in level flight BARO Set Knob Sets barometric pressure display in inches of mercury and hectopascals • Displays attitude, airspeed, altitude, and baro setting • The airplane battery will power the system if normal electrical power is lost
Recall the function of the Source Input Select Panels
Selects opposite side system. FLT MGT selects opposite FMS.
Recall the function of the Inertial Reference System (IRS) control panel
NAV OFF Light
• ADIRU is off
• ADIRU is in align mode
• ADIRU failure
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
• The inertial reference function of the ADIRU provides air data and inertial reference information to the PFDs and NDs
• ADIRU-1 is powered by the EMER AC bus and backed up by the aircraft battery if
normal AC power is lost
• ADIRU-2 is powered by the R AC bus and backed up by an independent battery for a minimum of 30 minutes if normal AC power is lost (retains heading, attitude and
position
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 within 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
Recall features of the Flight Data Recorder
• Records 25 hours of flight operation
• Operative when aircraft parking brake is released and either fuel switch is on
• An EVENT switch on the overhead panel can be used to mark an event on the
recorder memory
Recall the function of the Automatic Dependent Surveillance-Broadcast (ADS-B) Transponder Panel
Altitude Range Selector
Allows shifting of TCAS coverage up and down from baseline:
• ABV – sets TCAS display from 2700 feet below to 7000 feet above own
airplane.
• N – sets TCAS display from 2700 feet below to 2700 feet above own airplane.
• BLW – sets TCAS display from 7000 feet below to 2700 feet above own
airplane
