DESCRIPTION & OPERATION
PA-28-181, ARCHER ID
Multi-Function Display (continued)
Traffic Advisory System (TAS) - Optional (continued)
TAS Alerts:
Traffic is displayed according to TCAS symbology using four different
symbols.
l. Non-Threat Traf f ic - An open white diamond with black center that
indicates traffic is beyond a 6 nm range and greater than ± 1200 feet from
the requesting aircraft.
2. Proximity Advisory (PA) - A solid white diamond indicating that the
intruding aircraft is within ± 1,200 feet and 6 nm range, but is still not
considered a TA threat.
3. Traffic Advisory (TA)-A solid yellow circle that indicates that traffic has
met the criteria for a traffic advisory and is considered to be potentially
hazardous. A yellow TRAFFIC annunciation is displayed at the top left
of the attitude indicator on the PFD and an alert is heard in the cockpit,
advising "Traffic", along with additional voice information about the
•
bearing, relative altitude, and approximate distance from the intruder that
triggered the TA. For example, the voice alert "Traffic, 11 o'clock, high,
•
three miles" would indicate that the traffic is in front of and slightly to
the left of the own aircraft, above own altitude, and approximately three
nautical miles away. A T A wi
II
be displayed for a minimum of
8
seconds,
even if the condition(s) that triggered the TA are no longer present.
4. Traffic Advisory Off Scale - On the Traffic Map page a half TA symbol
indicating a traffic advisory (TA), which is detected but is outside the
range of the map will be displayed at the edge of the scale on the azimuth
of the detected traffic. On the map page the off-scale traffic advisory is
provided in a text box located on the lower left comer of the map.
Traffic information for which TAS is unable to determine the bearing (non­
bearing tra.ffic) is displayed in the center of the Traf
f
ic Map Page or in a
banner at the lower left corner of maps other than the Traffic Map Page on
which traffic can be displayed.
TAS customization options are available to the pilot by depressing the
MENU key while on the Navigation Map Page, and then selecting "Map
Setup" then "Traffic" Group. TAS traffic may also be displayed on the
•
Navigation Map by selecting the MAP softkey and then selecting TRAFFIC
softkey.
