    Description of modification

    The TAS-620 actively monitors the airspace around your aircraft by interrogating the transponder of nearby aircraft. The range and bearing of 
    all transponder equipped aircraft is displayed on one of 3 optional displays (Garmin 400/500 series, Multi-Hazard Display or ½ ATI display). This provides the flight crew with an excellent situational awareness with respect 
    to surrounding air traffic. Various level of proximity alerts are provided both visually and aurally. This system meets the requirement of TSO-C147.
