feed back bus (allows feedback and comparison of critical flight parameters)
What does the AHRS system accomplish?
Supplies attitude and heading (pitch, roll, yaw) information to EIS, auto flight, stall protection and other systems

Regarding the display units, which color indicates status messages, advisories, lines, references, and armed autoflight modes?
White
With regard to the display units, which color indicates active controlling modes and functions?
Green
The fixed area on the Captain’s MFD contains ______ information and the First Officer’s contains ______ information.
PFCS (Powered Flight Control Surface) // Flap position & Hydraulic pressure/quantity
T/F: Cyan colors on the displays indicate pilot selectable items.
TRUE
Which color on the display units indicates FMS-related data or pointers?
Magenta
T/F: On the display units, magenta indicates FMS-related data or pointers.
TRUE
T/F: If a red indication is displayed on an instrument, it is a low priority indication.
FALSE, red = immediate crew notification and timely corrective action is necessary
On the display units, a ______ text message is used for messages that require subsequent action.
Flashing
T/F: Brackets are used on the displays for certain messages regarding flight crew instructions or required crew actions.
TRUE
The AHRS system includes how many operating modes?
3 Modes (ALIGN, NORMAL, SLAVE)
AHRS is able to operate in one of two reduced performance modes, ______ and ______, during non-normal operations.
BASIC // DG
T/F: If BASIC mode or DG mode is present on the AHRS, the crew is still allowed to takeoff.
FALSE, takeoff with BASIC or DG is prohibited
Takeoff is prohibited if either AHRS is in ______ mode or ______ mode.
BASIC // DG
The AHRS enters the alignment mode how many seconds after a power-on self test?
5 seconds after self test
A ______ colored annunciator on the ATT/HDG ALIGN switch light illuminates during the alignment.
Amber
T/F: After AHRS alignment is complete, the system automatically enters the NORMAL mode.
TRUE
Which ADU input is used to correct for acceleration-induced attitude errors?
True Airspeed is used
If both MFD selectors are not in SYS, pressing and holding any page button will display the system on the ______.
ED (Engine Display)
Which source will automatically display on MFD 1 during a failure?
ED (Engine Display)
T/F: If onside ADU inputs fail completely, the AHRU will automatically revert to the opposite side’s ADU.
TRUE
T/F: In SLAVE mode, the AHRUs use analog magnetic headlong data from the flux valves to set inertial heading data.
TRUE
T/F: If true airspeed information from the ADU is not available, the BASIC mode is automatically entered.
TRUE
Each index control panel controls certain elements on the associated pilot’s ______.
PFD
Display items that are adjusted by the index control panel include ______.
Speed bugs
Barometric pressure
Decision altitude (DA) or Minimum descent Altitude (MDA)
Adjustable speed bugs available for takeoff include V1, V2, and ______.
VR
If changes are not made to the V speeds within ______ seconds of pressing the speed bug on the index control panel, the box disappears.
5 seconds
T/F: The BARO SET knob is used to set the barometric correction, displayed on the bottom of the altitude tape on the MFD.
FALSE, altitude tape is on PFD
What happens if the DH or MDA setting on the PFD is set to 0 feet?
The display is removed from the PFD
The EFIS control panels are used to control the ______.
