If you don’t fly in airspace where a transponder is required today, you do not have to equip with ADS-B Out. However, there are several reasons why you may still want to consider equipping:
- The ability to fly in ADS-B airspace at any time if the need arises.
- Enhanced safety and additional situational awareness from traffic and free weather information (if you also opt for ADS-B In or have a portable ADS-B receiver).
- Increased airframe value as the January 1, 2020, mandate approaches. (Because of the number of aircraft forecast to require ADS-B installation, owners could find full shops and experience scheduling delays as the deadline approaches.)
- Maintain airframe value after the January 1, 2020, deadline passes. (Aircraft that are not ADS-B equipped are likely to fall in value.)
- More efficient search and rescue. ADS-B’s GPS-based surveillance provides more accurate information about an aircraft’s last reported position. This is because ADS-B Out avionics transmit data approximately once every second, compared to a ground-based radar’s sweep rate of 3-15 seconds.
- More efficient spacing and optimal IFR routing in nonradar environments, including the Gulf of Mexico, mountainous regions of Colorado, and lower altitudes in some parts of Alaska.
