FAA Addresses Privacy Concerns Related to ADS-B
Originally published in BusinessAir Magazine, November 2019, Volume 29, No. 11.
With the FAA compliance date approaching, the privacy concerns of aircraft owners and operators related to ADS-B (Automatic Dependent Surveillance – Broadcast) had been increasing, but the FAA has recently announced a solution to alleviate the apprehensions.
What is ADS-B Out? ADS-B is technology that uses an aircraft’s onboard global positioning system (GPS) to transmit the current position, speed, flight number and, most importantly, whether the aircraft is climbing, descending or turning. The current radar-based system is not able to recognize and process information regarding climb, descent or turns. The transmitted information is sent to ATC and other aircraft. The current radar system sends updates once every two to twelve seconds. However, aircraft equipped with ADS-B Out capabilities transmit data every second. So, not only do the transmitted updates contain more information, including data on climb, descent and turns, but the updates also take place far more frequently.
