4 Data Tag
These two digits indicate, in hundreds of feet, the relative altitude of the
intruder aircraft. For example, +10 means the intruder aircraft is
1,000 feet above you. A positive data tag is displayed above the traffic
symbol to emphasize that the intruder aircraft is above your aircraft.
Similarly, a negative data tag is displayed below the traffic symbol. If the
intruder is at the same altitude as your aircraft, 00 will be displayed
above the traffic symbol.
The data tag for a vertically out of range TA stays at the maximum or
minimum altitude number of the current altitude display mode until the
intruder aircraft comes within the altitude limits of the altitude display
mode. The
SKY497 only displays data tags for altitude reporting aircraft.
