10.6.4 Displaying TAWS-B Data
TAWS uses yellow (caution) and red (warning) to depict terrain and obstacles
alerts relative to aircraft altitude. Colors are adjusted automatically as the aircraft
altitude changes. The colors and symbols shown below are used to represent
terrain, obstacles, and threat locations. Obstacles are removed when more than
2,000 ft below the aircraft.
