General

The TCAS computer puts traffic into these four groups:

· Other traffic shows as a white open diamond, and the altitude readout is white text

· Proximate traffic shows as a solid white diamond, and the altitude readout is white text

· Traffic advisory (TA) shows as a solid amber circle, and the altitude readout is amber text

· Resolution advisory (RA) shows as a solid red square and the altitude readout is red text.

Each traffic symbol has an altitude readout. A vertical motion arrow is also shown if the airplane vertical speed is greater than 500 feet per minute (fpm). The traffic symbols show in these navigation display modes:

· Center (CTR) MAP

· Expanded (EXP) MAP

· Expanded (EXP) VOR

· Expanded (EXP) APP.
