Abstract

An aircraft automatic fault reporting system having a plurality of ARINC 429 low-speed data buses between the aircraft maintenance control panel and the aircraft communications addressing and reporting system provides two-way communication therebetween. Detected faults through an eight-digit fault code are by means of a transient logic circuit under certain conditions of the aircraft communications and addressing systems provided to maintenance personnel thereby eliminating flight crew use of FRM'"'"'s.

Claims

1. In an automatic fault reporting system:

means for providing fault code information;

an aircraft communication addressing and reporting system for providing a signal representative of a ready condition and a discrete signal representative of a transmission complete and received condition;

a transient logic circuit responsive to said fault code information and said signal representative of a ready condition of an aircraft communications addressing and reporting system for receiving said fault code information;

said transient logic circuit dumping said fault code information for transmission through said aircraft communications addressing and reporting system in response to the presence of said signal representative of a ready condition of said aircraft communications addressing and reporting system, and further repeating said dumping of said fault code information for transmission through said aircraft communications addressing and reporting system until receiving said discrete signal representative of said transmission complete and received condition from said aircraft communications addressing and reporting system.
