Overview Navigation Flight Planning Hazard Avoidance Additional Features Appendix F APPENDIX F: GENERAL TIS-A INFORMATION NOTE: Aircraft without an operational transponder are invisible to TIS-A. WARNING: Do not rely solely upon the display of traffic information for collision avoidance maneuvering. The traffic display does not provide collision avoidance resolution advisories and does not, under any circumstances or conditions, relieve the pilot's responsibility to see and avoid other aircraft. WARNING: Do not rely solely upon the display of traffic information to accurately depict all of the traffic within range of the aircraft. Due to lack of equipment, poor signal reception, and/or inaccurate information from aircraft or ground stations, traffic may be present that is not represented on the display. The Traffic Information Service (TIS-A) provides traffic advisory information to nonTAS/TCAS-equipped aircraft. TIS-A is a ground-based service providing the relative locations of all ATCRBS (Air Traffic Control Radar Beacon System) Mode-A and Mode-C transponder equipped aircraft within a specified service volume. The TIS-A ground sensor uses real-time track reports to generate traffic notification. The aera displays TIS-A traffic information on the Navigation Map. Surveillance data includes all transponder-equipped aircraft within the coverage volume. The aera displays up to eight traffic targets within a 7.5-nm radius, from 3,000 feet below, to 3,500 feet above the requesting aircraft. TIS-A VS. TAS/TCAS The main difference between the Traffic Information System (TIS-A) and Traffic Advisory (TAS) or Traffic Collision Avoidance Systems (TCAS) is the source of surveillance data. TAS/TCAS uses an airborne interrogator with a half-second update rate, while TIS-A utilizes the terminal Mode-S ground interrogator and accompanying data link to provide a five-second update rate. TIS-A and TAS/TCAS have similar ranges. Appendices Index 190-02017-20 Rev. A Garmin aera 660 Pilot's Guide 151

APPENDIX F:
GENERAL TIS-A INFORMATION
NOTE:
Aircraft without an operational transponder are invisible to TIS-A.
WARNING:
Do not rely solely upon the display of traffic information for collision
avoidance maneuvering.
The traffic display does not provide collision avoidance
resolution advisories and does not, under any circumstances or conditions, relieve the
pilot’s responsibility to see and avoid other aircraft.
WARNING:
Do not rely solely upon the display of traffic information to accurately
depict all of the traffic within range of the aircraft.
Due to lack of equipment, poor signal
reception, and/or inaccurate information from aircraft or ground stations, traffic may be
present that is not represented on the display.
The Traffic Information Service (TIS-A) provides traffic advisory information to non-
TAS/TCAS-equipped aircraft.
TIS-A is a ground-based service providing the relative
locations of all ATCRBS
(Air Traffic Control Radar Beacon System)
Mode-A and Mode-C
transponder equipped aircraft within a specified service volume.
The TIS-A ground
sensor uses real-time track reports to generate traffic notification.
The aera displays
TIS-A traffic information on the Navigation Map.
Surveillance data includes all
transponder-equipped aircraft within the coverage volume.
The aera displays up to
eight traffic targets within a 7.5-nm radius, from 3,000 feet below, to 3,500 feet above
the requesting aircraft.
TIS-A VS. TAS/TCAS
The main difference between the Traffic Information System (TIS-A) and Traffic
Advisory (TAS) or Traffic Collision Avoidance Systems (TCAS) is the source of surveillance
data.
TAS/TCAS uses an airborne interrogator with a half-second update rate, while
TIS-A utilizes the terminal Mode-S ground interrogator and accompanying data link to
provide a five-second update rate.
TIS-A and TAS/TCAS have similar ranges.
