Lessons Learned – Avionics Line Replaceable Unit Built in Tests
Year: 2010
Abstract: Abstract:
The Space Shuttle Program Orbiter Avionics Line Replaceable Unit's (LRU) were designed with limited or no diagnostic capability. The lack of fault isolation capability resulted in flight processing schedule impacts and collateral damage to flight hardware. New LRU designs need to provide an Integrated Built In Test that will verify the LRU internal components and external outputs of the LRU are functioning nominally.
