Generic DataLink Message Encapsulation Structure
As indicated in Section 1 above, the FA5000 DataLink CVR also includes an ARINC
429 OMS output interface (Pins 50/51) that provides a Label 350 CVR status word
output once per second. This word, in its entirety, along with any DataLink Label 270
or 276 input status words are also recorded as part of the DataLink stream. This
provides a complete representation of the CVR DataLink input, and overall CVR sta-
tus, within the recorded DataLink stream.
