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 go-around mode
RETARD for landing retard mode
THRUST for control mode at FLC
TO for take-off 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.
