Relative altitude, when available, is displayed above or below the corresponding intruder symbol in
hundreds of feet (Figure 6-164). When this altitude is above own aircraft, it is preceded by a '+' symbol; a
minus sign '-' indicates traffic is below own aircraft.
A vertical trend arrow to the right of the intruder symbol (Figure 6-164) indicates climbing or descending
traffic (at least 500 feet per minute) with an upward or downward-pointing arrow respectively.
If the intruding aircraft is providing ADS-B track information, this is displayed as a vector line extending
beyond the traffic symbol in the direction of the track (Figure 6-165).
Flight IDs may also be displayed with traffic symbols; see the Flight IDs discussion in this section for more
information.
On-ground aircraft with Mode S transponders are not displayed.
