Overview GPS Navigation Additional Features Hazard Avoidance Flight Planning Hazard Avoidance TIS Alerts A TIS audio alert is generated whenever the number of Traffic Advisories on the aera screen increases from one scan to the next. Limiting Traffic Advisories only reduces the "nuisance" alerting due to proximate aircraft. For example, when the first Traffic Advisories appear on the TIS display, the user is alerted audibly. So long as a single aircraft remains on the TIS display, no further audio alert is generated. If a second (or more) aircraft appears on the screen, a new audio alert is sounded. If the number of Traffic Advisories on the TIS display decreases and then increases, a new audio alert is sounded. The TIS audio alert is also generated whenever TIS service becomes available. The following TIS audio alerts are available: • "Traffic"-TIS traffic alert received. • "Traffic Not Available"-TIS service is not available or out of range. Adjusting TIS audio: 1) From the 'Home' Screen, touch Tools > Setup > Sound. 2) Touch the TIS Audio On/Off Button to toggle the terrain audio on/off, or touch the Alerts Icon to mute both TIS and Terrain alerts. Or:  Touch the Alerts buttons to select an alert volume (0-10). Traffic Warning Window When a traffic threat is imminent, the Traffic Warning Window is shown. The Traffic Warning Window shows a small pop-up thumbnail map in the lower left corner. The Range Rings on the pop-up alert are spaced every whole mile/kilometer/nautical mile. Touch the Traffic Warning Window to acknowledge and remove it. NOTE: The Traffic Warning Window is disabled when the aircraft ground speed is less than 30 knots or when on the approach leg of a route.
