This document focuses on reaching common design objectives for Target System data loading systems and circumventing repeatedly occurring issues rooted in system design.
Commonly desired design objectives include:
• Architectural choices – Simplify the upload process of LRU Target Systems of the same type
• Reducing incorrect failure behaviors: a “bricked” LRU Target System after transfer interruption
• Performance: Optimized load times using commonly known design tradeoffs
Operational constraints to be avoided are:
• Unexpected operational behavior
• Not fully realized performance and violation of expected load times
• Corrupted or inconsistent states of installation
• The inability to reload/recover LRU target systems after upload failures
Since the target data loading function resides within the LRU Target Systems, which are often subject to airborne certification processes, incorrect behavior is costly to correct, and timelines for correction are long, in contrast to errata within a non-airborne data loader, which can often be updated swiftly.
