CS 25.1460 Data link recorders
(See AMC
25.1460)
(a) Each recorder performing the data link recording function required by the operating rules must be approved and must be installed so that it will record data link communication messages related to air traffic services (ATS) communications to and from the aeroplane.
(b) Each data link recorder must be installed so that:
(1) (i) it receives its
electrical power from the bus that provides the maximum reliability for the
operation of the recorder without jeopardising service to essential or
emergency loads; and
(ii) it remains powered for as long as possible
without jeopardising the emergency operation of the aeroplane;
(2) there is an aural or visual means for
pre-flight checking of the recorder for the proper recording of data in the
storage medium; and
(3) if the recorder is deployable, it complies
with CS 25.1457(d)(7).
(c) If the recorder is not deployable, the
container of the recording medium must be located and mounted so as to
minimise the probability of the container rupturing, the recording medium
being destroyed, or the underwater locating device failing as a result of any
possible combinations of:
(1) impact with the Earth’s surface;
(2) the heat damage caused by a post-impact fire; and
(3) immersion in water.
If the
recorder is deployable, the deployed part must be designed and installed so as
to minimise the probability of the recording medium being destroyed or the
emergency locator transmitter failing to transmit (after damage or immersion
in water) as a result of any possible combinations of:
(1) the deployment of the recorder;
(2) impact with the Earth’s surface;
(3) the heat damage caused by a post-impact fire; and
(4) immersion in water.
(d) The container of the data link recorder must comply with
the specifications applicable to the container of the cockpit voice recorder
in CS 25.1457(g).
EASA regulations mandate approved data link recorders on large aeroplanes to capture air traffic service communications. Recorders must have reliable power, pre-flight checks, and protect the recording medium from impact, fire, and water damage. Deployable recorders must ensure emergency locator transmitter functionality post-crash. Recorder containers must meet cockpit voice recorder standards.
