Phase II SBIR project in Aircraft Fleet Monitoring has been awarded to Mitek Analytics LLC by NASA. In this project, MitekAn team is developing Big Data Analytics software for aircraft monitorig from FOQA (Flight Operation Quality Assurance) data. FOQA data includes hundreds of aircraft channels sampled at one second interval collected at each flight for aircraft fleet. Most of the airlines collect FOQA data for ensuring operations safety. MitekAn is developing software that is specifically focused on airframe and propulsion performance, as well as integrity of flight sensors and actuators. MitekAn's analytics rely on aerospace engineering knowledge. The vast amounts of data are distilled into compact reports that inform Condition Based Maintenance (CBM), fuel economy efforts, and safety risk management of aircraft.
