and an excerpt re ACARS p50-51
Interpretation of the messages
Interpretation of the maintenance-related messages is made delicate by the
following factors:
this type of message is only transmitted once, at the first occurrence. It
can only indicate that a fault has appeared. If the fault has disappeared, no
message is transmitted to indicate this,
some messages concerning the aircraft’s configuration such as stall or
overspeed warnings are not recorded,
message-timing by the CMC is accurate to within one minute,
the order in which these messages are transmitted does not necessarily
correspond to the associated sequence of events,
the limited rate of communication by satellite does not make it possible to
determine directly the time of message reception precisely to the nearest
second,
in the CFR, a class 1 fault message is not necessarily accompanied by a
cockpit ef-fect, and it is possible that a cockpit effect message is not the
consequence of a fault message.
