The EFD1000/500 MFD will display intruders prioritized in the order received from the
congured trac sensor. The EFD1000/500 MFD includes three threat levels using TCAS
symbology; trac advisory (amber circle), proximity advisory (cyan diamond), and other
trac (hollow cyan diamond). All intruders within the current display range and the
selected altitude lter are shown. Intruders generating a trac advisory with range and
bearing data are displayed as a trac symbol at the location representing its position
relative to the ownship symbol (Figure 5-73).
5.3.2.1.1. Display of Trac Symbols
The EFD1000/500 MFD displays intruder information from the sensor with the threat
level assigned by the sensor. The sensor and type of trac system denes the threat
data, range, bearing, altitude, and altitude trend. Each trac symbol is positioned at a
location representing the relative range and bearing to the ownship symbol.
A data block is given for each reported intruder displaying the type, relative altitude,
and intruder vertical direction (as acquired from the sensor). The data block text color
is the same as the trac symbol, amber for Trac Advisory and white for proximity and
other trac (Figure 5-74).
When an intruder’s altitude and vertical speed are available, they are displayed as part
of the on-screen data block. The relative altitude is shown as two digits indicating the
relative altitude dierence, in hundreds of feet, from the ownship. The altitude value for
trac above the ownship is preceded by a plus symbol (+) and is on top of the symbol.
The altitude value for trac below the ownship is preceded by a minus symbol (-) and is
on the bottom of the symbol.
An arrow next to the trac symbol gives the direction of vertical movement in relation
to the ownship. Intruders climbing or descending at a rate greater than 500 fpm display
an up-arrow (climbing), or down-arrow (descending) to the right of the trac symbol.
Trac that is at co-altitude with the aircraft and has no vertical trend is indicated by an
altitude value of 00 below the trac symbol.

NOTE
Trac that is within 100 feet of the ownship displays an

as appropriate. .
