SPO.IDE.A.150 Data link recording
GENERAL
(a) The letters and expressions in Table 1 of AMC1 SPO.IDE.A.150 have the following meaning:
(1) C: complete contents recorded.
(2) M: information that enables correlation with any associated records stored separately from the aeroplane.
(3) *: applications that are to be recorded only as far as is practicable, given the architecture of the system.
(4) F1: graphics applications may be considered as AOC messages when they are part of a data link communications application service run on an individual basis by the operator itself in the framework of the operational control.
(5) F2: where parametric data sent by the aeroplane, such as Mode S, is reported within the message, it should be recorded unless data from the same source is recorded on the FDR.
(b) The definitions of the applications type in Table 1 of AMC1 SPO.IDE.A.150 are described in Table 1 below.

EASA air operations require recording of data link communications, including CPDLC, ADS-C, D-FIS, and AOC messages. The regulations specify which message types and parameters, like weather maps and aircraft parameters, must be recorded for various application types to ensure operational control and safety. Correlation with other records is essential.
