ROLL SCALE AND POINTER
At the top of the blue display is a roll scale and pointer. The scale covers ± 60 degrees from level attitude.
The scale is marked as follows:
- Small triangle at 0 degrees of bank angle
- Large tick marks at ± 30 and ± 60 degrees
- Small tick marks at ± 10 and ± 20 degrees
- Small triangle at ± 45 degrees
The roll pointer moves in reference to the center of the aircraft symbol and indicates aircraft roll angle.
SLIP/SKID INDICATOR
The slip/skid indicator is a small rectangle located below the roll pointer. The slip/skid indicator is driven by lateral accel-
eration. It turns with the roll pointer and moves laterally with respect to the base of the roll pointer.
One brick width deflection of the rectangle is equivalent to a displacement of one ball width on a conventional slip/skid
indicator.
VERTICAL DEVIATION DISPLAY
The vertical deviation display is shown to the right of the attitude display. It is a white fixed scale employing a moving
deviation icon. The color of the deviation icon is green when displaying the on-side data and is amber when displaying
cross-side data.
The scale has two dots above and below a reference line with each dot representing a 1/4 degree deviation above or below
the glideslope beam. There is a diamond for glideslope data and a star for VNAV data.
GLIDESLOPE FLAG
During an ILS, with invalid glideslope information, a red boxed GS flag is displayed, replacing the pointer and scale.
