Preliminary
located at a position on the screen that indicates the
relative bearing and range of the intruder aircraft.
In general, the
SKY899 issues a TA when it detects an
intruder aircraft within
30 seconds of a possible collision,
or within a
0.55 nmi horizontal radius and a ±800 ft
relative altitude range of your aircraft. (See chapter
4 for
details.)
Vertical Trend Arrow A vertical trend arrow
indicates that the intruder aircraft is ascending (up
arrow) or descending (down arrow) faster than
500 fpm.
No arrow is shown for intruder aircraft in level flight, or
for those moving vertically slower than
500 fpm, or for
non-altitude-reporting intruder aircraft.
