More AFIT (2 of 2)
Failure Classes
Single and multiple concurrent failures may be introduced at the assembly interface . Failures may be static, dynamic, sequential, conditional, intermittent and even combinational.
Tests may be performed to confirm, amongst other things, that:-
- Failure symptoms (modes) have been correctly predicted.
- Failures can be localised as anticipated.
- Anticipated repair times are accurate.
- Equipment testability and Built In Test are as effective as specified.
- Maintainability Demonstrations will be satisfactory.
Sentient AFIT Applications include:-
- Hardware Failure Analysis.
- Testability Verification.
- Quantification of BITE Effectiveness.
- Fault Tree Analysis (FTA) Verification.
- Determination of Failure Dormancy.
- Maintainer Training.
- Failure Modes and Effects Analysis (FMEA) Verification.
- Determination of the Effects of Single or Multiple Part Failures.
- Verification of System Corrective Maintenance Procedures.
- Quantification of Failure Latency.
- Maintainability Demonstration.
