PRIMARY DISPLAY SYSTEM -APPROACH MODE NCD AND FAIL CONDITIONS
General
The display function in the AIMS cabinets evaluates inputs from the airplane systems.
A no computed data (NCD) status causes information on the display to go away.
A fail status causes information on the display to go away and a fail flag to show.
Approach Mode NCD and Fail Conditions
The chart below shows the NCD and fail conditions for the approach mode.

PRIMARY DISPLAY SYSTEM -CENTERED VOR MODE
General
The centered VOR mode shows selected VOR course and course deviation. The display shows the full 360 degrees of the compass rose. The centered VOR mode has a heading up display.
Display Data
There is some data that is the same as the data on the centered approach mode. Other data is unique to the VOR mode.
Heading and track is the same as the approach mode.
Selected VOR course shows as a magenta pointer that rotates around a fixed airplane symbol. The selected VOR course also shows digitally in the upper right corner.
VOR course deviation shows as a deviation bar on a dot scale. The dot scale rotates around the airplane symbol.
TO shows airplane direction to the tuned station. FROM shows airplane direction from the tuned station. A pointer and the TO or FROM indication shows this data.
The decoded VOR station identifier shows in the upper right corner for a tuned VOR station when the receiver gets a valid identifier from the ground station. With no valid identifier, the tuned frequency shows. Below the frequency/identifier field is the selected course. DME distance to the co-located DME station shows below the selected VOR course.
The radio source shows at the upper right between the heading readout and the frequency/identifier.
ADF/VOR bearing information is the same as the approach mode.
ADF/VOR switch position, frequency, and DME distance is the same as the approach mode.
Selected heading or track is the same as the approach mode.
Ground speed, wind data and true airspeed is the same as the approach mode.
TCAS information shows as a message below the DME distance in the upper right corner. Set the TFC switch on the EFIS CP to see the data.
TCAS status information shows below the WXR data field to indicate TCAS selection; TA ONLY (TCAS is not computing RA) or TCAS TEST (TCAS is in the test mode).

PRIMARY DISPLAY SYSTEM -EXPANDED VOR MODE
General
The expanded VOR mode shows the selected VOR course and course deviation. The display shows 90 degrees of the compass rose. The airplane symbol is at the bottom of the display and the apex of the symbol represents the present position of the airplane.
Display Data
The expanded VOR mode shows data that does not show or is different on the centered VOR mode.
The airplane heading shows as digits on top of a 90 degree arc and is the same as the centered VOR mode. The track line extends from the tip of the airplane symbol to the compass rose.
Selected course shows as a magenta line.
VOR course deviation scales and symbols look slightly different. They function the same as the centered VOR mode.
Only the head or the tail of the VOR/ADF bearing pointers shows.
Selected heading or track shows as a magenta dashed line that extends from the apex of the airplane symbol to the selected heading or track pointer.
TCAS information shows as messages in the right center of the display and as symbols on the display. Set the TFC switch on the EFIS CP to see the information.
TCAS status and mode information shows below the WXR data field to show:
*
TCAS selection
*
TFC and mode data
*
TA ONLY (TCAS is not computing RA)
*
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.
