Garmin GDL84: Entry-Level ADS-B

Lets assume you own a vintage Piper Cherokee, Cessna 172 or Grumman Tiger, to name a few entry-level rides. Perhaps it is equipped with a basic navcomm, older Mode C transponder and non-WAAS GPS-or no panel GPS at all because you fly with a tablet computer or portable GPS. Youve probably discovered the dilemma in finding a complete mandate-compliant ADS-B In and Out solution that wont require a complicated installation. Garmin is attempting to solve that with its new GDL84 ADS-B transceiver, a product that trickles down from the flagship GDL88 system.
