traffic system or ADS-B traffic that is not correlated will also be displayed for
the flight crew. The correlation of traffic by the GDL 88H ensures that only the
most accurate, and no duplicate, traffic targets are displayed for the flight crew’s
situational awareness.
In addition, the GDL 88H will use its air-ground logic or inputs to automatically
switch the active traffic from Standby to Operate when transitioning from
ground to air, and from Operate to Standby when transitioning from air to
ground.
If the GDL 88H fails then external traffic device data is no longer sent to the
display.
When interfaced to an active traffic system, traffic alerts are provided as
follows:
Alerts will be provided by the TCAS system for targets tracked solely
via TCAS AND targets that tracked via TCAS and ADS-B which are
correlated.
Alerts will be provided by the GDL 84H/88H for targets that are
tracked solely by ADS-B.
The optional interfaced display’s Pilot’s Guides and supplements provide
additional information regarding the functionality and control of the traffic
device.

Power to the GDL 84H/88H is provided through a circuit breaker labeled
“ADS-B”.
