Review of Methodologies for Aircraft Sensors Fault Detection and Correction

The air data system is responsible for estimating vital flight parameters for correct and safe operation of aircraft. One of the main components in this system is the Pitot tube sensor which is responsible for measuring the total pressure and in conjunction with the static pressure port estimates parameters like altitude, air speed, vertical speed and Mach number. The Pitot tube is prone to failure because of external adverse atmospheric conditions. The current research aims to develop a solution to the aircraft loss of control caused by an unreliable airspeed indication by introducing the concept of a digital twin that estimates flight parameters based on simulation and monitors actual flight parameters.
