When interfaced to a TAS or TCAS system, traffic alerts are provided as follows: Traffic TAS/TCAS CSA Alert Correlated? Alert Active? Active? Aural Alert Source Yes Yes N/A TCAS/TAS Yes No N/A None No Yes Yes TCAS/TAS (prioritized) GDL 88 No No Yes GDL 88 Table 4-1 TAS/TCAS Traffic Alerts Visual Alert Source TCAS/TAS None TCAS/TAS GDL 88 GDL 88 NOTE: Aural traffic alerts from the GDL 88 are suppressed when below 500 feet Radar Altitude or Height Above Terrain. When a GDL 88 and TAS/TCAS system are integrated, the GDL 88 controls the Altitude Display and operating mode of the TAS/TCAS system using the air/ ground logic in the GDL 88, as well as from the mode controls available on the interfaced display. 4.2.3 No-Heading Source Traffic Information When a GDL 88 and TAS/TCAS are integrated in an aircraft without a heading source, they are subject to the following limitations: • While on the ground, display of TCAS traffic and ADS-B traffic are mutually exclusive. • TCAS (heading referenced traffic) and ADS-B traffic are allowed to be displayed on the traffic page concurrently in a Track Up orientation while airborne, but bearing of the TCAS targets relative to ADS-B targets are slewed by the crab angle of the aircraft. • Traffic is not displayed on the moving map with ground features depicted. Traffic is always available for display on the traffic page. 4.2.4 Conflict Situational Awareness (CSA) Conflict Situational Awareness is an alerting algorithm that provides TCASlike Traffic Alerts on ADS-B, ADS-R, and TIS-B targets to enhance situational awareness. The GDL 84/88 issues an aural alert when a Conflict Situational Awareness (CSA) alert is displayed, for example "Traffic! Two O'clock, Low, Two Miles." 4-6 Garmin GDL 84/88 ADS-B Transceiver Pilot's Guide 190-01122-03 Rev. E

TAS/TCAS Traffic Alerts
NOTE
:
Aural traffic alerts from the GDL 88 are suppressed when below 500
feet Radar Altitude or Height Above Terrain.
When a GDL 88 and TAS/TCAS system are integrated, the GDL 88 controls
the Altitude Display and operating mode of the TAS/TCAS system using the air/
ground logic in the GDL 88, as well as from the mode controls available on the
interfaced display.
4.2.3
No-Heading Source Traffic Information
When a GDL 88 and TAS/TCAS are integrated in an aircraft without a heading
source, they are subject to the following limitations:
• While on the ground, display of TCAS traffic and ADS-B traffic are mutually
exclusive.
• TCAS (heading referenced traffic) and ADS-B traffic are allowed to be
displayed on the traffic page concurrently in a Track Up orientation while
airborne, but bearing of the TCAS targets relative to ADS-B targets are slewed
by the crab angle of the aircraft.
• Traffic is not displayed on the moving map with ground features depicted.
Traffic is always available for display on the traffic page.
4.2.4
Conflict Situational Awareness (CSA)
Conflict Situational Awareness is an alerting algorithm that provides TCAS-
like Traffic Alerts on ADS-B, ADS-R, and TIS-B targets to enhance situational
awareness.
The GDL 84/88 issues an aural alert when a Conflict Situational Awareness
(CSA) alert is displayed, for example “Traffic! Two O’clock, Low, Two Miles.”
