Main conclusions of RFI Big Data Flight Tests (from IT)
24th June 2015 AG MaDICS - Lyon
Flight Tests Use Case is well appropriated to Big Data concept & technologies.
POC results have demonstrated that Big Data technologies provide better performances (taking into account extraction & rendering steps).
POCs have been realized in a very short time: huge optimizations & techninal design improvements are possible.
Transition to Big Data can be done in several steps.
First step can be realized with limited impact on legacy clients (Visage, …)
All vendors propose Hadoop/Map-Reduce as target solution for extraction step
Different solutions have been proposed for storage/rendering steps (HDFS, NoSQL, MPP, …) Results are difficult to compare. NOSQL Design has an important impact on performances
Big Data technologies provide new business opportunities (combining new data sources & existing ones, real time analysis, ….)

Big Data application « Data retrieval»
Save flight hours
• Easy search will be generalized
« search autopilot on & altitude > 30000 ft & Mn>0.8 & bank > 5° then
and plot the vertical load factor »
• Opportunities to bridge with other database (configuration, logs,…)
Compare versions in the frame of incremental development
