Description

  1. TASK 71-00-00-810-001 EEC Fault Messages

    1. General

      This TASK gives the EEC fault messages which are made available through the ARINC data bus. The ARINC data is carried as a lable/bit (ARINC 429) and as a clear language message (ARINC 356). This TASK also gives a definition of the lable/bit and a reference to the corrective procedure for the ARINC 356 clear language message. The corrective procedures for the ARINC 356 clear language messages are given in TASK 71-00-00-810-002.
