TIS Operational Procedures
TIS warns the user with voice and visual trafc advisories whenever
it predicts an intruder to be a threat. The user should not start
evasive maneuvers using information from the GPSMAP 396 screen
or on a trafc advisory only. The display and advisories are intended
only for assistance in visually locating the trafc, due to the lack in
resolution and coordination ability. The ight crew should attempt to
visually acquire the intruder aircraft and maintain a safe separation
in accordance with the regulatory requirements and good operating
practice. If the ight crew cannot visually acquire the aircraft,
they should contact ATC to obtain any information that may assist
concerning the intruder aircraft. Based on the above procedures,
minor adjustment to the vertical ight path consistent with air trafc
requirements are not considered evasive maneuvers.
The TIS Trafc Advisory (TA) should alert the crew to use
additional vigilance to identify the intruding aircraft. Any time
the trafc symbol becomes a yellow circle or a voice warning is
announced, conduct a visual search for the intruder. If successful,
maintain visual contact to ensure safe operation.

Conditions for Trafc Advisories
TIS shows a Trafc Advisory (TA) on the GPSMAP 396 when an
intruder aircraft approaches your aircraft on a course that intercepts
(dened by a 0.5 nm horizontal radius and a relative altitude of ±
500 ft) your course within 34 seconds.
