NAVIGATION / SURVEILLANCE Flashcards
1 | What does the ON BAT light indicate? [ FCOM-DSC-34-10-20 ]

6 | How does the ADIRS panel indicate that an IR is in ALIGN mode? [ FCOM-DSC-34-10-30 ]
º Before any engine is started (displayed on E/WD):
- IR IN ALIGN X MN memo appears in green when at least one active IRS is being aligned
º When one engine is started (displayed on E/WD):
- IR IN ALIGN X MN memo appears in amber during IRS alignment
- IR NOT ALIGNED is displayed as an ECAM Caution Message if the alignment of one IRS is faulty
- IR IN ATT ALIGN appears in green during the IR alignment in Attitude Mode
7 | What does a flashing white align light mean (older panel with keypad)? [ FCOM-DSC-34-10-20 ]
º There are three reasons that the white align lights will flash:
- There is no current position
- The position is incorrect
- The aircraft moved during alignment
8 | How is the crew alerted to the FMGS having no current position, an incorrect position or if the aircraft has moved during the alignment? [ FCOM-DSC-34-10-20 ]
º IR IN ALIGN X MN memo pulses in green on the E/WD
9 | How do you fast align an IR? [ FCOM-PRO-SUP-34, FCOM-NOR-SOP-06 ]
º Select each ADIRS selector OFF and then back to NAV (one at a time) within 5 sec
10 |What does the IR pushbutton do on the newer AIDIRS panel? [ FCOM-DSC-34-10-20 ]
º Inertial data output of the respective IR is disconnected
11 |What does steady illumination of the amber IR FAULT light indicate? [ FCOM-DSC-34-10-20 ]
º A fault affects the respective IR
12 |What does flashing illumination of the amber IR FAULT light indicate? [ FCOM-DSC-34-10-20 ]
º Attitude and heading may be recovered in ATT mode (you have lost the navigation portion)
13 |What does the amber ADR FAULT light indicate? [ FCOM-DSC-34-10-20 ]
º A fault is detected in the Air Data Reference portion
14 |Does turning the IR Mode Rotary Switch to OFF also turn off the ADR? [ FCOM-DSC-34-10-20 ]
º Yes
15 |Can you turn the ADR OFF and still have the IR? [ FCOM-DSC-34-10-20 ]
º Yes
16 |When is a full alignment required of the ADIRU required? [ FCOM-PRO-NOR-SOP-07 ]
º Full alignment of the IRS is required;
- Before the first flight of the day, or
- When there is a crew change or
- When the GPS is not available and the NAVAIDS coverage is poor on the expected route, or
- When the GPS is not available and the expected flight time is more the 3 hours
- When any portion of the flight is conducted in Class II Navigation
17 |Describe the process for a full alignment of the ADIRS when the FLAPS are not retracted.
[ FCOM-PRO-NOR-SOP-07 ]
º If the FLAPS are not retracted the flight crew should not set all ADIRS to OFF at the same time
º In order to perform the alignment with the FLAPS not retracted, set a single IR mode selector to OFF for more than 5 seconds, then set that IR mode selector to NAV. Repeat this for each remaining IR mode selector switch.
18 |What would be missing on the on the Captain’s PFD and ND if IR1 failed or was turned OFF?
[ FCOM-DSC-34-10-10 ]
º Attitude and navigation information would be lost. ATT and HDG flags will be displayed on the PFD and MAP NOT AVAIL will be on the ND
19 |What action would recover the attitude and navigation information if IR1 failed or was turned off?
[ FCOM-DSC-34-10-20 ]
º Selecting CAPT 3 on the EIS switching panel ATT/HDG selector
20 |What would restore the lost altitude and airspeed information if IR1 failed or was turned off?
[ FCOM-DSC-34-10-20 ]
º Selecting CAPT 3 on the EIS Switching Panel AIR DATA Selector
21 |Pressing the SYS pushbutton does what? [ FCOM-DSC-34-70-40 ]
º Inhibits all EGPWS warnings except TERR system
22 |What does an amber FAULT light in the SYS pushbutton indicate on the GPWS panel? [ FCOM-DSC-34-70-40 ]
º Any failure of basic GPWS modes 1 through 5
23 |What does LDG FLAP 3 ON light indicate? [ FCOM-DSC-34-70-40 ]
º “Too Low Flaps” inhibited for a Flap 3 landing
24 |When would you press the FLAP MODE pushbutton? [ FCOM-DSC-34-70-40 ]
º To avoid nuisance warnings when landing with flaps less than 3
25 |If the TERR mode failed, does it affect the basic GPWS? [ FCOM-DSC-34-70-40 ]
º No
26 |How many transponders are installed? [ FCOM-DSC-34-50-10 ]
º 2
27 |Does illumination of the ATC FAIL light indicate loss of all transponder capability? [ FCOM-DSC-34-50-20 ]
º No – only the selected transponder has failed
28 |What capabilities does the RADAR system have? [ FCOM-DSC-34-60-10 ]
º Weather avoidance
º Turbulence detection
º Terrain mapping
º Predictive windshear detection
29 |What would prevent the weather display on the ND? [ FCOM-DSC-31-45 ]
º Mode selector in PLAN
º TERR selected ON
30 |When is WX/TURB mode available? [ FCOM-DSC-34-60-30 ]
º At ranges of 40 nm or less
31 |Does predictive windshear detection work when the RADAR system is switched OFF? [ FCOM-DSC-34-60-20 ]
º Yes, if the windshear switch is in AUTO
32 |What is the scanned area of the predictive windshear detection feature? [ FCOM-DSC-34-10 ]
º Up to 5 nm ahead of the aircraft when the aircraft is below 1,500 feet AGL
33 |When are predictive windshear alerts inhibited? [ FCOM-DSC-34-10 ]
º When landing below 50 feet AGL
34 |How many RADAR systems are installed? [ FCOM-DSC-34-10 ]
