When the FD is engaged on the ground the AFDS goes into takeoff mode and the TO
annunciators are indicated for both lateral and vertical modes. The flight director commands
runway heading and a pitch attitude for positive rate of climb. After takeoff a different lateral
and vertical modes would be selected to continue the flight. The same is true for a go-around.
GA would be annunciated for both modes and would be cleared on climbout through selection of
different modes.
Lateral Modes
The lateral mode selected on the autopilot is annunciated in the lower right corner of the EADI.
The upper position (white) shows the armed mode. For example, if in heading hold (HDG
HOLD) mode and the localizer (LOC) is selected to capture the white LOC and the green HDG
HOLD would show. When the aircraft intercepts the localizer the white LOC will disappear and
a green LOC will appear in place of HDG HOLD. This indicates the autopilot is now tracking
the localizer.
The ROLL OUT annunciator is associated with the autoland capability of the aircraft. When in a
CAT II or CAT III situation and using the autoland's Land 2 or Land 3 function (explained later)
a ROLL OUT annunciation will be seen which indicates the aircraft is ready to (white) or is
performing (green) the runway rollout procedure. Because of space constraints the ROLL OUT
annunciator appears as R OUT.
Vertical Modes
The vertical mode selected on the autopilot is annunciated in the lower left corner of the EADI.
The upper position (white) shows the armed mode. For example, if in altitude hold (ALT
HOLD) mode and the approach mode (APP) is engaged there would be a white G/S annunciator
to indicate arming for glideslope capture on top of the green ALT HOLD annunciator. Then
upon glideslope intercept the white G/S will disappear and the green G/S will appear in place of
the ALT HOLD annunciator. This indicates the autopilot is now tracking the glideslope path.
The FLARE annunciator is associated with the autoland capability of the aircraft. When in a
CAT II or CAT III situation and using the autoland's Land 2 or Land 3 function, the FLARE
annunciation which indicates the aircraft is ready to (white) or is performing (green) the FLARE
maneuver, will illuminate. Additionally the autothrottle will annunciate IDLE during the flare.
Radar Altitude
A digital radar altitude displays actual height above the ground up to 2,500 feet. Between 500
and 2,500 feet the display is calibrated at 50 foot increments. Below 500 feet the calibration
becomes 10 feet. There is a DH window that is adjusted using the altimeter DH bug adjustment.
When the radio altitude is below the selected DH the digits turn orange.

Speed Deviation Scale
Commonly known as the fast/slow gauge, this display will show how far off the aircraft is from
the autopilot selected airspeed. If too fast the pointer goes to the F side. If too slow the pointer
moves toward the S side. It is calibrated at +/- 10 kias.
Runway Closure Indicator
When in the Approach mode and below 200ft AGL, a small runway symbol will appear in the
EADI and will gradually rise up into the pitch bar as you close in on the ground. This is a nice
backup in low visibility to give you yet another indication that ground contact is coming. This
symbol we have here is not 100% accurate for the 767 but it does the job.
Course Deviation Indication (CDI) and Glideslope Scales
When tuned to a VOR there will be a course deviation scale. The Glideslope scale is only
present when a valid ILS is tuned in.
Flight Director
The flight director only requires to be turned on/off with the FD switch on the AFDS panel.
When turned on a horizontal and vertical pink bar will appear on the face of the EADI.
The flight director uses a double cue with 2 bars. The basic idea is to adjust aircraft pitch and roll
so that the pink Pitch Bar (horizontal line) and pink Roll Bar (vertical line) are always centered.
Pitch towards the bars to center them.

Rose Mode
(See Figure 1)
The default mode of the EHSI is the ROSE mode. When the Source Select knob is on "R" the
ROSE mode is displayed.
