An optical sensor (10) for an aircraft includes two detectors (14, 16), a light source (12), and a controller (100). The detectors (14, 16) are oriented along detector paths and have tilt angles and fields of view. The detectors (14, 16) are configured to detect light reflected from an illumination volume and to generate detector signals that correspond to intensities of detected light. The tilt angles are equal such that each detector (14, 16) is oriented in an opposite direction within a plane containing a light source path and the detector paths. The light source (12) is oriented along the light source path and is configured to illuminate the illumination volume which overlaps with the fields of view within a predetermined distance range. The controller (100) is configured to receive the detector signals, detect whether a cloud is present based upon the detector signals, determine a cloud phase, and calculate a density of the detected cloud.
