Boom elevation estimation using hoist cable system

Abstract:

A system for detecting a sensor fault of an aerial refueling boom. The system comprises a data collector configured to receive sensor data from a plurality of sensors and determine an aerial refueling boom elevation angle of the aerial refueling boom based on the sensor data, wherein the sensor data comprises at least one of cable length data, a dynamic pressure data or aerial refueling boom position data. The system further comprises a processing unit configured access a database table in a storage unit to determine an estimated aerial refueling boom elevation angle, a comparator configured to compare the estimated aerial refueling boom elevation angle to the determined aerial refueling boom elevation angle, and a fault detector configured to generate a sensor fault signal based on the comparison.
