Q

6 | How does the ADIRS panel indicate that an IR is in ALIGN mode? [ FCOM-DSC-34-10-30 ]

A

16
Q

16 |When is a full alignment required of the ADIRU required? [ FCOM-PRO-NOR-SOP-07 ]

A

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
Q

17 |Describe the process for a full alignment of the ADIRS when the FLAPS are not retracted.
[ FCOM-PRO-NOR-SOP-07 ]

A

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
Q

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 ]

A

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
Q

19 |What action would recover the attitude and navigation information if IR1 failed or was turned off?
[ FCOM-DSC-34-10-20 ]

A

º Selecting CAPT 3 on the EIS switching panel ATT/HDG selector

20
Q

20 |What would restore the lost altitude and airspeed information if IR1 failed or was turned off?
[ FCOM-DSC-34-10-20 ]

A

º Selecting CAPT 3 on the EIS Switching Panel AIR DATA Selector

21
Q

21 |Pressing the SYS pushbutton does what? [ FCOM-DSC-34-70-40 ]

A

º Inhibits all EGPWS warnings except TERR system

22
Q

22 |What does an amber FAULT light in the SYS pushbutton indicate on the GPWS panel? [ FCOM-DSC-34-70-40 ]

A

º Any failure of basic GPWS modes 1 through 5

23
Q

23 |What does LDG FLAP 3 ON light indicate? [ FCOM-DSC-34-70-40 ]

A

º “Too Low Flaps” inhibited for a Flap 3 landing

24
Q

24 |When would you press the FLAP MODE pushbutton? [ FCOM-DSC-34-70-40 ]

A

º To avoid nuisance warnings when landing with flaps less than 3

25
Q

25 |If the TERR mode failed, does it affect the basic GPWS? [ FCOM-DSC-34-70-40 ]

A

º No
