AAMPS Project Goals ● Modernize and standardize the data systems on all AOC platforms – minimize dissimilarities. ● Make it scalable for use in both heavy and light aircraft applications. ● Simplify routine maintenance, troubleshooting, and project preparations. ● Support AOC standard instrumentation, third-party systems, and provide a solid growth path for future hardware and instrumentation. ● Use commercially available off-the-shelf (COTS) hardware/software – minimize custom interfaces.
