What happens if the associated ADS button is pushed in?
a. Reverts the ADS source:

90 seconds
What is important about the IESS time to align?
Do not move the aircraft during this time. If so, it could cause inflight attitude indication errors that may not be noticeable on the ground

Magenta
What color is the course needle when using VOR/LOC?
Green
What color is the course needle when using cross side data?
Amber
The primary method of radio tuning is via the _______. The backup method is the __________.
MCDU/ CCD
When will the FD automatically display?
TOGA button actuation, autopilot is activated, or windshear detection
When is TOGA mode deactivated?
Another vertical mode is selected or autopilot is activated
What does the TOGA button do?
On ground: activates takeoff guidance crossbars
In flight: activates go around guidance
What are some of the vertical modes of the flight guidance system?
FLCH, ALT, VNAV, VS, and FPA
What are the default autopilot modes?
ROLL and FPA
When is the ‘minimums’ knob set to RA?
ILS CAT II
When is the minimums knob set to BARO?
ILS CAT I, LNAV/VNAV, and VOR
What is the indication of a successful test on the Universal DVDR?
a. CVR PASS/FAIL lights flash for 10 seconds the illuminate steady green and no fail messages on EICAS
If not selected on the MCDU, when does the DVDR flight data recording automatically operate?
First engine start
What are you checking when you press the DVDR test button (Honeywell)?
Press and hold the test button for 3 seconds and verify no fail messages displayed on EICAS
What are you checking when you press the DVDR test button (Universal)?
Press and hold the test button for 2 seconds. Verify no fail messages displayed on EICAS and observe the following results:
- FDR 1 and CVR 1 PASS/FAIL lights flash for 10 seconds. After 10 seconds, the FDR 1 and CVR PASS/FAIL light illuminates in steady green, indicating the completion of a successful test.
- After DVDR 1 test finishes, the DVDR2 test automatically starts. Verify the following result: FDR 2 and CVR 2 PASS/FAIL lights flash for 10 seconds. After 10 seconds, the FDR 2 and CVR 2 PASS/FAIL light illuminates in steady green, indicating the completion of a successful test.
The oxygen mask microphone and flight deck speakers are automatically activated as soon as the oxygen mask stowage box doors are opened (T/F).
True
ACARS data is dedicated to which radio?
VHF 3 is dedicated to ACARS but can be used for radio communications if needed.
Who does the interphone system connect?
a. Enables intercommunication between flight deck occupants, enables communication between the flight deck and flight attendants, and enables communication between the flight deck and ramp personnel.
