RESOLUTION ADVISORY (RA)
a solid red square indicates that the
intruding aircraft is projected to be a
collision threat. tCaS II calculates
that the intruder has reached a point
where a resolution advisory is
necessary. the time to closest
approach with the intruder is now
between 15 and 35 seconds
depending on your altitude. the
symbol appears together with an
appropriate audio warning and a
vertical maneuver indication on the
ra/VSI. Voice announcements are
listed later in this section.
Note: For NVIS types only, the
intruder symbol appears as a red
filled square with white border.
Associated altitude and direction
arrows are red.
this aircraft is now 600 feet below
your altitude and still climbing at 500
feet per minute or greater.
a synthesized voice announces a
vertical maneuver command, such
as:
“CLIMB, CLIMB.”
The pilot should smoothly but firmly
initiate any required vertical maneu-
ver within 5 seconds (2.5 seconds
for an “Increase RA” or “Reversal
RA”) from the time the RA is posted.
An intruder must be reporting altitude
in order to generate an RA.
Therefore, the RA symbol will always
have an altitude tag.
