PRIMARY DISPLAY SYSTEM -CENTERED APPROACH MODE
Selected heading shows as M shaped box on the outer edge of the compass rose. When selected heading and actual heading are equal, the box fits around the heading pointer. Selected track shows as a cursor on the inner edge of the compass rose.
This data shows in the upper left corner:
*
Ground speed
*
True airspeed
*
Wind data.
Ground speed and true airspeed shows as digital readouts. Wind data shows as digital readouts and a rotating arrow.
TCAS information shows as a message below the DME distance in the upper right corner.
TCAS status information shows below the WXR data field to indicate TCAS selection, TA ONLY (TCAS is not computing RAs) or TCAS TEST (TCAS is in the test mode).

PRIMARY DISPLAY SYSTEM -EXPANDED APPROACH MODE
General
The expanded approach mode shows ILS course and course deviation and navigation information. The display shows 90 degrees of the compass rose. The airplane symbol is at the bottom of the display and the point of the symbol represents the present position of the airplane along the flight path.
Display Data
The expanded approach mode shows data that does not show or is different on the full rose approach mode.
Heading and track, the airplane heading shows as digits on top of a 90 degree arc and is the same as the full approach mode. The track line extends from the tip of the airplane symbol to the compass rose.
Selected runway course shows as a magenta pointer.
Localizer and glide slope deviation scales and symbology are slightly different in appearance. The function is the same as the centered approach mode.
VOR/ADF bearing pointers head or the tail of the applicable pointer shows.
Selected heading or track show as a magenta dashed line that extends from the selected heading or track pointer to the apex of the airplane symbol.
TCAS information shows as messages in the right center of the display and as symbols.
TCAS status and mode information shows below the WXR data field to show this TCAS selection (TFC) and mode data:
*
TA ONLY (TCAS is not computing RAs)
*
TCAS TEST (TCAS is in the test mode)
*
TCAS OFF
*
TCAS FAIL (a fault exist in TCAS).
Data that does not change includes:
*
Identifier, frequency and DME distance
*
The radio source
*
ADF/VOR switch position, frequency and DME distance
*
Ground speed, wind data and true airspeed.

PRIMARY DISPLAY SYSTEM -APPROACH MODE FAILURE FLAGS
General Failures of input sources cause data to go away from the display and failure flags to show. A left or right VOR failure causes VORL or VORR to show on the ND. To see the flag, put the applicable switch on the EFIS control panel in the VOR position.
All the flags are amber.
The captain’s and first officer’s NDs operate independently.
Failure Flags
A heading (HDG) input failure to the ND causes HDG to show.
The DME co-located with the ILS, or left or right VOR failure causes DMEL or DMER to show on the ND. To see the flag for DMEs co-located with the VOR stations, put the applicable VOR switch on the EFIS CP in the VOR position.
The localizer (LOC) input failure causes the LOC to show on the ND. The localizer flag is independent of the glideslope flag.
A glide slope (G/S) failure causes G/S to show on the ND. The glide slope flag is independent of the localizer flag.
A left or right ADF failure causes ADFL or ADFR to show on the ND. To see the flag, put the applicable switch on the EFIS control panel in the ADF position.
