Patent abstract
Onboard systems and methods for early detection that an aircraft has flown into a volcanic ash plume embedded within a water vapor cloud having a concentration of a volcanic ash which would be dangerous to an aircraft. The detection method generally comprises the steps of measuring the infrared emission characteristics of a jet engine exhaust and generating a detection signal when the intensity of infrared emissions at or near a spectral peak wavelength exceeds a threshold.
