Preliminary
Data Tag
These two digits indicate, in hun-
dreds of feet, the relative altitude of the intruder
aircraft. In this case, +
04
means the intruder
aircraft is
400
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
is displayed above the
traffic symbol.
The data tag for a vertically out of range
TA
stays
at the maximum or minimum relative altitude
number of the current vertical display mode until
the intruder aircraft comes within the relative
altitude limits of the vertical display mode. The
SKY899
only displays data tags for altitude report-
ing aircraft. Non-altitude-reporting aircraft are
considered to be at the same altitude as your awn
aircraft.
Traffic Advisory (TA)
A
TA
consists of a symbol on-
screen and a “traffic, traffic” message on the cockpit
speakers or headset. When an intruder aircraft that meets
the
TA
criteria described in chapter

display mode), the corresponding symbol is this circle
