Q

ADIRS Panel:
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

ADIRS Panel:
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

ADIRS Panel:
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

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

ADIRS Panel:
What action would recover the attitude and navigation information if IR1 failed or was turned off?
FCOM-DSC-34-10-20

A

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

20
Q

ADIRS Panel:
What would restore the lost altitude and airspeed information if IR1 failed or was turned off?
FCOM-DSC-34-10-20

A

Selecting CAPT 3 on the EIS Switching Panel AIR DATA Selector

21
