GM1 CAT.IDE.H.195 Data link recording
DEFINITIONS AND ACRONYMS
(a) The letters and expressions in Table 1 of AMC1 CAT.IDE.H.195 have the following meaning:
C: Complete contents recorded
M: Information that enables correlation with any associated records stored separately from the helicopter.
*: Applications that are to be recorded only as far as is practicable, given the architecture of the system.
F1: Graphics applications may be considered as AOC data 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.
F2: Where parametric data sent by the helicopter, 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 CAT.IDE.H.195 are described in Table 1 below.

EASA regulations mandate data link recording on helicopters for air operations. This includes recording various message types like CPDLC, ADS-C, D-FIS, TWIP, D-ATIS, OCL, DCL, graphics, and AOC messages. The goal is to capture communication data for safety and operational analysis, ensuring correlation with other records.
