Abstract
A flight data recorder for reliable, high-speed storage of flight data employs a distributed, modular architecture in which an array of controller/memory modules is arranged in parallel controller/memory chains and the memory in the individual controller/memory modules is partitioned into submodules. This distributed architecture allows failed controller/memory modules or failed memory submodules to be bypassed, thus providing fault tolerances for both controller and memory functions. The modular architecture allows the number of controller/memory modules to be easily configured to accommodate any required storage size, while the number of parallel controller/memory chains can be configured to accommodate any required data rate.
