1. 2016 Maintenance Innovation Challenge
Interrogative Diagnostics Solution (IDS)
PROBLEM STATEMENT
Currently aircraft fault detection and fault isolation (FD/FI) diagnostics is a painfully long process.
“Replacement until fixed” is the nominal solution to avionics problems
“No Trouble Found” returns of perfectly functional black boxes costs the DoD millions of dollars annually
What technology exists to qualitatively reduce MTTR and false failure rates on today’s platforms?
BENEFITS
IDS is a system that facilitates:
A “System of Systems” FD/FI Capability
Uses real time data from the system and Fault Logs
Establishes Accurate/Repeatable Diagnostics
Maximizes detailed BIT data and applied algorithms
Transforms system BIT data into discrete Mx actions
Minimizes Costly False Removals
WRA Isolation and/or wiring in Multi WRA subsystems
BIT data is cross correlated to validate results and not as a single point reference
Eliminates Time Consuming Troubleshooting
Accomplished via automatic means
Can be integrated with any Mx documentation
TECHNOLOGY SOLUTION
Incorporates system engineering knowledge into a defined IDPS SW architecture (through XML) to create an accurate, repeatable, expert- maintainer solution for all skill levels
Based on system data, not operator interpretation
Performs FD/FI beyond basic fault code interpretation
Procedures are written in XML, interpreted by the diagnostic task processor, and can be simulated, executed in a lab against real equipments, or on actual AC for testing and validation
Enables automation of procedures
Significantly reduces test times
Enables the diagnostic procedures to be updated real time
Updates can be made without affecting system software
