Abstract
A method for prognostic health monitoring (PHM) of aircraft-based angle of attack (AoA) sensors includes sampling analog or digital AoA data sensed by one or more AoA sensors. The method includes sampling concurrent sensor health data (e.g., orientation, current, voltage, temperature) from monitoring sensors within each AoA sensor. The method includes, based on the sampled AoA data and concurrent sensor health data, determining a current responsiveness factor (RF) for each individual AoA sensor. The method includes retrieving prior or historical RF data for each individual AoA sensor. The method includes, based on the current and historical RF data, determining an RF trend over time for each AoA sensor. The method includes, when the RF for any AoA sensor trends beyond a responsiveness threshold, generating an alert for preventative maintenance personnel on the ground, the alert indicative of specific fault conditions of the AoA sensor depending on the responsiveness threshold breached.
