TIS Operational Procedures
TIS warns the user with voice and visual traffic advisories whenever
it predicts an intruder to be a threat. The user should not start
evasive maneuvers using information from the GPSMAP 496 screen
or on a traffic advisory only. The display and advisories are intended
only for assistance in visually locating the traffic, due to the lack in
resolution and coordination ability. The flight 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 flight 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 flight path consistent with air traffic
requirements are not considered evasive maneuvers.
The TIS Traffic Advisory (TA) should alert the crew to use
additional vigilance to identify the intruding aircraft. Any time
the traffic 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.
