Text in magenta in force from 30 October 2025

1. Aeroplanes first issued with an individual CofA on or after 8 April 2014 that have the capability to operate data link communications and are required to be equipped with a CVR, shall record on a recorder, where applicable:

   1. data link communication messages related to ATS communications to and from the aeroplane, including messages applying to the following applications:

      1. data link initiation;

      2. controller-pilot communication;

      3. addressed surveillance;

      4. flight information;

      5. as far as is practicable, given the architecture of the system, aircraft broadcast surveillance;

      6. as far as is practicable, given the architecture of the system, aircraft operational control data; and

      7. as far as is practicable, given the architecture of the system, graphics;

   2. information that enables correlation to any associated records related to data link communications and stored separately from the aeroplane; and

   3. information on the time and priority of data link communications messages, taking into account the system’s architecture.

2. The recorder shall use a digital method of recording and storing data and information and a method for retrieving that data. The recording method shall allow the data to match the data recorded on the ground.

3. The recorder shall be capable of retaining data recorded for at least the same duration as set out for CVRs in CAT.IDE.A.185.

4. If the recorder is not deployable, it shall have a device to assist in locating it under water. By 16 June 2018 at the latest, this device shall have a minimum underwater transmission time of 90 days. If the recorder is deployable, it shall have an automatic emergency locator transmitter.

5. The requirements applicable to the start and stop logic of the recorder are the same as the requirements applicable to the start and stop logic of the CVR contained in CAT.IDE.A.185(d) and (e).
