Cessna 172SP ADSB


ADS-B - Automatic Dependent Surveillance Broadcast

Automatic dependent surveillance — broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation.

Situational awareness

ADS-B makes flying significantly safer for the aviation community by providing pilots with improved situational awareness. Pilots in an ADS-B In equipped cockpit will have the ability to see, on their in-cockpit flight display, other traffic operating in the airspace as well as access to clear and detailed weather information. They will also be able to receive pertinent updates ranging from temporary flight restrictions to runway closings.

ADS-B enables improved safety by providing:

  • Radar-like IFR separation in non-radar airspace
  • Increased VFR flight following coverage
  • ATC final approach and runway occupancy, reducing runway incursions on the ground
  • More accurate search and rescue response — although ADS-B can transmit "aircraft down" data, the FAA has stated that there is no intention to perform even a study of ADS-B's effectiveness in an "aircraft down" situation, simply based on the fact that ADS-B equipment has no requirement to be crashworthy, as compared to the current "black box" recorder. ADS-B was demonstrated to the Civil Air Patrol (CAP) in March 2003 by AOPA via flight demonstrations for possible integration of the technology in CAP activities.
  • Helps pilots to see and avoid other aircraft
  • Cockpit final approach and runway occupancy
  • Visual separation in VFR and MVFR conditions
  • VFR-like separation in all weather conditions
  • Real-time cockpit weather display
  • Real-time cockpit airspace display
