ADS-B Technologies and Their Limitations - What You Should Know But Have Not Been Told
Date and Time:
Wednesday, September 12, 2018, starting at 19:30 Pacific Daylight Time Download Calendar File
Datong Sun
Brief Description:

ADS-B technologies are becoming increasingly popular among pilots. However, despite all the good things we know about ADS-B, we rarely hear people talk about their technical details and limitations. In this safety seminar, we will discuss:

  • Capabilities of different aircraft surveillance technologies: primary radar, Mode A, C, S, Multilateration (MLAT) and ADS-B
  • TIS-B, FIS-B, ADS-R and their limitations
  • What information are ADS-B Out equipped transponders squawking
  • What information is available in the FIS-B uplink and how often it is broadcasted
  • ADS-B service degradation in congested areas
  • FIS-B uplink vs. XM weather
  • Why some traffic may not show up even when your airplane is ADS-B Out capable
  • Why ADS-B traffic altitude is sometimes not so reliable
  • Things to remember when using portable ADS-B receivers (compared to panel mounted avionics)
  • and more…

Datong Sun is a Software Engineer by training and pilot by passion. He obtained his private pilot certificate while still in college and has since added instrument rating, advanced and instrument ground instructor to his collection. His recent projects include the open source Pitot ADS-B receiver. While making Pitot, Datong had the chance to go through some pretty lengthy ICAO and FAA technical documentation and found lots of interesting quirks about surveillance technologies that he would like to share with other pilots to help them make better decisions.

Join us to get some deeper insights on ADS-B and handheld receivers than you find in the typical reference and marketing materials!
