Mandate to deactivate some ADS-B transmissions

It is critical that aircraft only transmit ADS-B from approved equipment configurations. Transmissions from unapproved equipment configurations could mislead aircraft with ADS-B IN capabilities and could also mislead ATC.

It is the responsibility of aircraft owners and operators to ensure that their aircraft comply with the related CASA regulations.

The relevant CASA regulations have been in place for some years, and say :

“If an aircraft carries ADS-B transmitting equipment which does not comply with an approved equipment configuration, the aircraft must not fly in Australian territory unless the equipment is

(a) deactivated; or

(b) set to transmit only a value of zero for the NUCp or NIC.”
