Understanding ADS-B

At heart, ADS-B is a new way for Air Traffic Control to separate airplanes, but it can also offer free datalink weather and traffic. Here are 5 things to know before you upgrade to ADS-B:

  1. ADS-B Out avionics will be required by January 1, 2020 in most airspace where you need a Mode C transponder today.
  2. An approved WAAS GPS must be included in your ADS-B Out solution.
  3. ADS-B Out compliance must be with panel-installed equipment (no portables).
  4. ADS-B In equipage (for weather and traffic) is completely optional.
  5. Avionics are available from Garmin, Bendix/King, Appareo, Aspen and others, starting under $5,000.
