Navigation Flashcards
The following antennas are located on the top of the aircraft ?
- GPS #1 and #2
- ATC Transponder (Upper)
- Emergency Locator
Transmitter (ELT) - VOR/LOC Antenna, and
- VHF #1
Antennas in the radome ?
Weather radar and glide slope
The following antennas are located on the bottom of the aircraft ?
- DME #1 & #2
- TCAS
- ATC Transponder (Lower)
- Radio Altimeters
- ADF #1 & #2, and
- VHF #2 & #3
Should a crew member select a navigation source from the other side, the navigation source indication on the PFD for that crew member is displayed in ?
Yellow
If both pilots select the same navigation source, the
navigation source on both PFDs is displayed in ?
Yellow to alert the crew that only one navigation source is being used.
Switching between ARC and
PLAN format is achieved by a short press of the ?
FORMAT push button
information will NOT be displayed in PLAN format.
In the event of an EGPWS terrain alert, the display will automatically switch to ?
to ARC format and display terrain.
MFD navigation source will alternate between the associated FMS and VOR/ILS for display how ?
FORMAT push button pushed for >1s
The DATA pushbutton on the
EFIS control panel (EFCP) enables ?
displaying on the ND the ten nearest navigation aids, airports, or both.
What’s the ARCDUS ?
Audio and Radio Control Display Units
How do we access the VHF NAV particular page ?
Accessed with the EXP key
The rotation of the knob results in rotation of the selected course pointer and digital readout on the associated PFD and ND.
Variable rate tuning advances the course several digits when the knob is ?
is rotated rapidly
When VOR is the selected navigation source, one dot of deviation represents ?
5 degrees of deviation from the selected course
When ILS is the selected navigation source, one dot of deviation represents ?
1.25 degrees of deviation from the selected course. An expanded localizer scale is shown below the Electronic Attitude Direction Indicator (EADI). The expanded localizer scale is 6 times as sensitive as the localizer display with full scale deflection representing 0.416 degrees of deviation
When EMS is the selected navigation source, two dots or full scale deviation represents ?
5NM deviation from track in ENROUTE mode, 1NM deviation in TERMINAL mode, and 0.3NM deviation in APPROACH mode
During a dual FD ILS approach, an excessive localizer deviation below 1,200 feet AGL is indicated by ?
the expanded scale and pointer turning yellow and flashing for the first 5 seconds.
The Flight Mode Annunciators
(FMA) will display a LOC EXCESS DEV message
An ILS vertical deviation of 2 dots indicates ?
0.5 degrees of deviation from being on glide slope
An FMS vertical deviation of 2 dots when ENROUTE indicates ?
.
1,500 ft deviation, 500 ft in
TERMINAL mode, and 200 ft in APPROACH mode
If glideslope deviation goes off scale below 1200 feet AGL
during a dual FD approach, the pointer and scale ?
turn yellow and flash as long as the condition exists. The Flight Mode Annunciator (FMA) displays a flashing GS EXCESS DEV message
If a glideslope discrepancy is detected between ILS 1 and ILS 2, or between the navigation receiver output and the displayed parameter, the ‘G’ label turns ?
yellow, flashing for 5 seconds then becoming steady.
The Flight Mode Annunciator
(FMA) displays a GS MISMATCH message
The Flight Data Processing System (FDPS) compares the output of the VHF navigation receivers with what is displayed to the flight crew. Any
discrepancies are indicated by ?
by a MISMATCH message in the
FMA of both PFDs. The source of the message is indicated either by a LOC MISMATCH or a GS MISMATCH message
When DME distance is failed, or DME is out of range by what is shown ?
, 3 white dashes replace the numeric value
DME information is supplied to the ?
Audio and Radio System, the Input/Output Processors, the TCAS, the transponders, and the Flight Management System
What’s used by the FMS to calculate the BCP ?
VOR and DME navigation data, Barometric corrected altitude from Air data Unit provides slant range correction. GPS position, TAS and HDG information.
