Symbology; Vert Smart Key (Tas); Traffic Status Indicators; Off Scale - Garmin 20 Pilot's Manual

Symbology

Traffic is shown with either the relative or absolute altitude indicated above or below the target symbol. If the
traffic is below or equal to your ownship altitude, the label is shown below the symbol. If the traffic is above
your ownship altitude, the label is shown above the symbol. For traffic with no altitude information, the label
will be shown as dashes (---).
• Traffic shown with an amber filled circle corresponds to traffic generating an alerting condition
• Traffic shown with a cyan filled diamond corresponds to traffic generating an advisory condition
• Traffic shown with a cyan open diamond is considered "other traffic"

Traffic Status Indicators

Off Scale

If a Traffic Alert target is not shown on the display because the zoom level is set too high, an amber Traffic Off
Scale (OS) indicator will show on the display.

Standby (TAS)

If the traffic sensor is in the Standby Mode, a white TAS Standby message will show on the display.
