Regulatory Update for AEA Members in Australia

CASA responds to AEA concerns over ADS-B mandate
The AEA recently issued a letter to the Civil Aviation Safety Authority that expressed concerns from Australian AEA members regarding rumors of a potential extension of the ADS-B mandate. While some issues may be no more than rumors, they can sometimes turn into fact due to complacency. The letter from the AEA asked the CASA for a response to these rumors. In short, the CASA response to these concerns reconfirmed the fact that the CASA has no plans to extend the ADS-B mandate beyond 2017.
