Traffic Target Track Vector. Traffic Warning Window When the unit is on any page (other than the NAV Traffic Page or when a TAWS/Terrain, or Dead Reckoning pop-up is displayed) and a traffic threat is imminent, the Traffic Warning Window is displayed. The Traffic Warning Window shows a small thumbnail map which can take the user to the Traffic Page by pressing ENT, or go back to the previous page by pressing CLR. Traffic Page TIS Traffic data are displayed on two 400W/500W Series unit pages, the Traffic Page and the Map Page. The 500W Series unit can also be configured to display a traffic thumbnail window below the VLOC frequency window. Unlike other forms of traffic, TIS traffic does not require heading data to be valid on the map. The only difference between TIS and other traffic data occurs on the Traffic Page. If heading is available, then the traffic data are compensated and displayed as heading-up. If it's not available, the Traffic Page is a track-up display. It is labeled on the upper portion of the Traffic Page. Traffic Page Display Range Various display ranges can be selected for optimal display of TIS traffic information. To change the display range on the Traffic Page: Press RNG to zoom through the range selections which are: 12/6 NM, 6/2 NM, and 2 NM. Traffic Warning Window NOTE: The Traffic Warning Window is disabled when the aircraft ground speed is less than 30 knots or when an approach is active. 6 190-00356-30 Rev H
