ATAS does not alert to traffic on ground
ADS-B In traffic supports three applications:
AIRB: Basic Airborne Application
ATAS: ADS-B Traffic Advisory System
SURF: Surface Situation Awareness

alerts when airborne traffic trajectories pose a potential collision risk.
SURF provides additional situational awareness when you are on ground or
within the terminal environment.
