The FAA’s network of ADS-B transmitters is growing fast. In the past 18 months the number has mushroomed, and by the end of the year there should be at least 800 sites up and working. ADS-B, which the FAA officially mandated in 2010 for full adoption by 2020, is the NextGen surveillance technology, though sadly it will not stop us from having to keep our Mode-C transponders. There are added benefits: In addition to futuristic traffic capabilities, ADS-B gives pilots with ADS-B In capability (that is, those receiving the signal as well as transmitting it) in-cockpit weather for free.

Key Takeaways:
- The FAA's ADS-B transmitter network is rapidly expanding, projected to have at least 800 operational sites by the end of the year.
- ADS-B is the mandated NextGen surveillance technology for full adoption by 2020, but it does not replace the need for Mode-C transponders.
- Pilots with "ADS-B In" capability receive significant benefits, including advanced traffic information and free in-cockpit weather.
