WHAT EQUIPMENT WILL I NEED?
This is where most of the confusion about the ADS-B mandate arises, but really it’s not that complicated. If you never fly in the flight levels or internationally, you can get by with a universal-access transceiver broadcasting over the 978 MHz link, which is the same feed that transmits subscription-free weather and traffic data to properly equipped airplanes. If you fly at FL 180 or above, or outside the United States, you’ll need a 1090 MHz extended squitter unit. Both options are rule-compliant ADS-B Out solutions. You’ll also need a WAAS GPS receiver. If you also want to receive subscription-free weather and traffic information, you’ll need ADS-B In capability, which is built into many rule-compliant units or could be gained from an ADS-B portable device, such as the Stratus 2S from Sporty’s and Appareo or XGPS170D from Dual.
