CONFIGURABLE FLIGHT DATA ANALYSIS FOR TRENDS ANDudSTATISTICS ANALYSIS OF AVIONICS SYSTEMS-AN EMBEDDEDudPERSPECTIVE OF AN EFFICIENT FLIGHT DATA ANALYSIS

摘要

Federal Aviation Administration (FAA) policy on Flight Operations Quality Assuranceud(FOQA) indicates that FOQA is a voluntary safety initiative encouraging airline participation in FOQA. Itudis in the public interest with a necessary requirement that Airlines must document procedures for takingudcorrective action, when necessary in the interest of safety and airlines must provide FAA with access toudaggregate trend data. FAA issues final FOQA rule, in what it called a major step towards reaching itsud“Safer Skies” goal of cutting the commercial aviation accidents rate by substantially. FOQA programsudcurrently are conducted by airlines, certification authorities and engineering groups of airlines. FOQA isudprimarily a data collection, processing and analysis system used to improve the various disciplines ofudflight operations. The Digital Flight Data Recorder (DFDR) onboard provides a wealth of information forudrest of the analysis. This information can lead to improvements in aircrew training, maintenance andudconduct of safer flight operations. The system can analyze and report the various events, exceedences andudreports including statistics for the airline operators.udNational Aerospace Laboratories (NAL), Bangalore has designed and developed a software tool calledudNALFOQA, which is being used by major airlines in the country for flight safety operations and qualityudassurance activities. Airlines that have started using NALFOQA system have documented a great deal ofudfinancial benefit, operational efficiency, reduced insurance premium, better safety levels as well asudimproved training and safety of operations. NALFOQA focuses on the criticality issues to expose theudhidden aspects of flight safety part of aircraft information management system in terms of its designudcriticality, flight operational features with justifiedudUsage, quality assurance facts and figures as focused on the recorded data and a voluminous types ofudreports, charts, graphs and statistical information for very effective flight operations with professionallyuddocumented results.udThe paper presents the methodology of data processing for various fleet of aircrafts with controlledudparameter limits and conditions with logical envelops bounded by derived mathematical approaches forudthe trends and statistics of various systems and components of aircraft using NALFOQA. The qualityudassurance in terms of flight operations and avionics system diagnostics is realized by flight data analysis,udwhich is the heart of the system. This Paper also presents about the flight safety issues of the aviationudindustry in particular to the quality assurance areas of aviation using the techniques of data processingudand database management for the history of each and every aircraft including the engineering database
