GM1 CAT.IDE.A.195 Data link recording    

CAA ORS9 Decision No. 1

DEFINITIONS AND ACRONYMS

(a) The letters and expressions in Table 1 of AMC1 CAT.IDE.A.195 have the following meaning: C: complete contents recorded

M: information that enables correlation with any associated records stored separately from the aeroplane.

*:     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 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.

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 CAT.IDE.A.195 are described in Table 1 below.
