ADIRS Panel:
What does a flashing white align light mean (older panel with keypad)?
FCOM-DSC-34-10-20
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

moved during the alignment?

ADIRS Panel:
What does the IR pushbutton do on the newer AIDIRS panel?
FCOM-DSC-34-10-20
Inertial data output of the respective IR is disconnected
ADIRS Panel:
What does steady illumination of the amber IR FAULT light indicate?
FCOM-DSC-34-10-20
A fault affects the respective IR
ADIRS Panel:
What does flashing illumination of the amber IR FAULT light indicate?
FCOM-DSC-34-10-20
Attitude and heading may be recovered in ATT mode (you have lost the navigation portion)
ADIRS Panel:
What does the amber ADR FAULT light indicate?
FCOM-DSC-34-10-20
A fault is detected in the Air Data Reference portion
ADIRS Panel:
Does turning the IR Mode Rotary Switch to OFF also turn off the ADR?
FCOM-DSC-34-10-20
Yes
ADIRS Panel:
Can you turn the ADR OFF and still have the IR?
FCOM-DSC-34-10-20
Yes
ADIRS Panel:
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
ADIRS Panel:
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.
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
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
ADIRS Panel:
What action would recover the attitude and navigation information if IR1 failed or was turned off?
FCOM-DSC-34-10-20
Selecting CAPT 3 on the EIS switching panel ATT/HDG selector
ADIRS Panel:
What would restore the lost altitude and airspeed information if IR1 failed or was turned off?
FCOM-DSC-34-10-20
Selecting CAPT 3 on the EIS Switching Panel AIR DATA Selector
GPWS Panel:
Pressing the SYS pushbutton does what?
FCOM-DSC-34-70-40
Inhibits all EGPWS warnings except TERR system
GPWS Panel:
What does an amber FAULT light in the SYS pushbutton indicate on the GPWS panel?
FCOM-DSC-34-70-40
Any failure of basic GPWS modes 1 through 5

What does LDG FLAP 3 ON light indicate?
FCOM-DSC-34-70-40

GPWS Panel:
When would you press the FLAP MODE pushbutton?
FCOM-DSC-34-70-40
