The PFD displays trac 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 provided for each trac symbol with the relative altitude and vertical
direction (as acquired from the sensor). The data block text color is the same as the
trac symbol, amber for Trac Advisories and cyan for Proximity Advisories and Other
Trac (Figure 4-129).
The relative altitude is shown as two digits indicating the relative altitude dierence, in
hundreds of feet, from your aircraft. The altitude value for trac above the ownship is
preceded by a plus symbol (+) and is displayed under the symbol. The altitude value for
trac below the ownship is preceded by a minus symbol (-) and is displayed under the
symbol.
An arrow next to the trac symbol gives the direction of vertical movement in relation
to the your aircraft. Trac climbing or descending at a rate greater than 500 fpm are
given an up-arrow (climbing), or down-arrow (descending) to the right of the trac
symbol. Trac that is at the same altitude, with no vertical trend, is given an altitude
value of 00 below the trac symbol.
For example, the Trac Advisory shown in Figure 4-128 is 400 feet above your aircraft
and descending. No altitude information is shown in the data block when the altitude is
unavailable.
Trac Advisories that are outside the current range are indicated by a half-symbol at
the edge of the Navigation Display with the appropriate data block. Proximity Advisories
and Other Trac that are outside of the current range are not displayed.
When multiple trac symbols partially or completely overlap, the symbols are visually
stacked, with the highest priority alert data on top, obscuring the lower priority alert.
Figure 4-129
Trac Symbol Data Block
NOTE
Trac that is within 100 feet of the ownship shown an
altitude value of 00, above or below the trac symbol
as appropriate.
NOTE
When the trac is ying level, no arrow is shown.
When the trac is not reporting an altitude, neither the
arrow nor the altitude indication is shown.
NOTE
Depending on the position of the Trac Advisory at the
edge of the screen, the trac symbol data block may or
may notdisplay.
