Abstract

A water and ice detection and quantitative assessment system (“WIDQAS”) for moisture detection and assessment of water accumulation on an aircraft having an airframe that has at least one enclosed space within the airframe is described. The WIDQAS may include a plurality of sensors and a data measurement device. The plurality of sensors may be arranged in the at least one enclosed space within the airframe and each sensor of the plurality of sensors may be configured to detect a presence of moisture in the at least one enclosed space and generate a data measurement that is responsive to the detection of moisture in the at least one enclosed space. The data measurement device is in signal communication with the plurality of sensors and may be configured to record the data measurement for each sensor and record identifying information about the measurement during a flight of the aircraft.
