NCC.IDE.A.170 Data link recording
(a) Aeroplanes first issued with an individual CofA on or after 1 January 2016 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:
(i) data link initiation;
(ii) controller-pilot communication;
(iii) addressed surveillance;
(iv) flight information;
(v) as far as is practicable, given the architecture of the system, aircraft
broadcast surveillance;
(vi) as far as is practicable, given the architecture of the system, aircraft
operational control data; and
(vii) 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.
(b) The recorder shall use a digital method of recording and storing data and information and
a method for readily retrieving that data. The recording method shall allow the data to
match the data recorded on the ground.
(c) The recorder shall be capable of retaining data recorded for at least the same duration as
set out for CVRs in NCC.IDE.A.160.
(d) If the recorder is not deployable, it shall have a device to assist in locating it under water.
By 1 January 2020 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.
(e) 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
NCC.IDE.A.160(d) and (e).
NCC.IDE.A.170 AMC1 Data link recording
GENERAL
(a) As a means of compliance with NCC.IDE.A.170 the recorder on which the data link
messages are recorded may be:
(1) the CVR;
(2) the FDR;
(3) a combination recorder when NCC.IDE.A.175 is applicable; or
(4) a dedicated flight recorder. In that case, the operational performance requirements
for this recorder should be those laid down in EUROCAE Document ED-112
(Minimum Operational Performance Specification for Crash Protected Airborne
Recorder Systems), dated March 2003, including amendments No 1 and 2, or any
later equivalent standard produced by EUROCAE.
(b) As a means of compliance with NCC.IDE.A.170 (a)(2) the operator should enable
correlation by providing information that allows an accident investigator to understand
what data was provided to the aircraft and, when the provider identification is contained in
the message, by which provider.
(c) The timing information associated with the data link communications messages required
to be recorded by NCC.IDE.A.170 (a)(3) should be capable of being determined from the
airborne-based recordings. This timing information should include at least the following:
(1) the time each message was generated;
(2) the time any message was available to be displayed by the flight crew;
(3) the time each message was actually displayed or recalled from a queue; and
(4) the time of each status change.
(d) The message priority should be recorded when it is defined by the protocol of the data link
