THE HEALTH AND INTEGRITY OF AIRCRAFT SENSORS AND INSTRUMENTS PLAY A CRITICAL ROLE IN AVIATION SAFETY. HOWEVER, INACCURATE OR FALSE READINGS FROM THESE SAME SENSORS/INSTRUMENTS CAN LEAD TO IMPROPER DECISION-MAKING RESULTING IN SERIOUS IF NOT FATAL CONSEQUENCES. THIS PROPOSAL OFFERS A RESEARCH AND DEVELOPMENT (R&D) EFFORT TO DEMONSTRATE THE FEASIBILITY OF USING ADVANCED DATA ANALYSIS TECHNIQUES TO IDENTIFY FAILURES IN PITOT TUBES RESULTING FROM BLOCKAGE, ICING, OR MOISTURE. THESE DATA ANALYSIS TECHNIQUES WILL USE EXISTING ELECTRICAL SIGNALS OF PITOT TUBE SENSORS THAT RESULT FROM MEASURED PROCESSES DURING IN-FLIGHT CONDITIONS AND/OR INDUCED SIGNALS IN PRE-FLIGHT CONDITIONS TO DETECT ANOMALIES IN THE SENSOR READINGS.
