FCS Couple Arrow
The Fligth Control System (FCS) Couple Arrow is displayed below the Autopilot Status
Annunciation to indicate which FCS is active. Only 3 possibility exists:
® FCS coupled to the right side
¬ FCS coupled to the left side
« Both FCS are active.

FCS Couple Arrow (Cont’d)
The double arrow is only displayed during ILS approaches. The FCS Couple Arrow blinks for 5
seconds after the Couple Arrow has been altered in direction. This can be selected from the flight
guidance panel. A ghosted arrow indicates a failed FCS condition or an AFCS fail condition.

AP/FD Mode Guidance Cue
The guidance cue is a circle that is displayed in reference to the FPV. Tracking of the FD results
in a concentric display of the guidance cue and the FPV.
The guidance cue is displayed in the T/O mode one second after nose wheel lift off. The guidance
cue is removed during excessive airplane attitude, TCAS resolution advisories, loss of FD modes,
manual disengagement of the FD and at an approach height of 50 feet.
In the above example, the pilot or the autopilot has to roll the airplane to the right and pitch it down
in order to track the guidance cue.
Autothrottle Annunciation
The autothrottle mode is shown above the airspeed tape. The following modes can be displayed:
LIM for limiting speed condition
SPD for control of airspeed
GA for goaround
mode
RETARD for landing retard mode
THRUST for control mode at FLC
TO for takeoff
mode
During mode transition, the annunciation blinks for 5 seconds. When the autothrottle is
disengaged, the last active mode flashes for 5 seconds and is then timed out.

Altitude Tape
The altitude tape displays the current barometric altitude. The altitude tape consists of a vertical
line with marks indicating every 100 ft increment and chevrons at every 500 ft increment.
The altitude tape can move outboard to the edge of the display in order to enable greater lateral
movement of the FPV in a conformal view.
Altitude Readout
The digital readout can display altitudes between −980 feet and 65,000 feet at 20 foot increments.
A minimum of 3 digits is always displayed. For negative altitude, the minus sign is displayed in
place of the one thousand digit.
A metric altitude readout is available and displayed below the altitude readout. It is derived from
the barometric altitude, and converted in meters. It is graduated into 5 meters increments.

Altitude BARO Set Readout
The BARO set readout is located below the altitude tape, in hectopascal (542 to 1084) or in inches
of mercury (16.00 to 32.00) as indicated by the barometric set format. The BARO set readout is
displayed when the selected BARO set value is adjusted by the pilot and for a 10 second period
there after.
