A method of operating an optical icing conditions sensor includes transmitting (402), with a transmitter, a light beam and thereby illuminating an illumination volume. A receiver array receives (404) light over a range of receiving angles. The receiver array is configured to receive light having the wavelength over a receiver array field of view which overlaps with the illumination volume. A controller measures (406) an intensity of light received by the receiver array. The controller determines (410) that a cloud is present if the intensity is greater than a threshold value. The controller calculates (412) scattering profile data of the light received by the receiver array if a cloud is determined to be present, which includes an angle of a scattering intensity peak within the range of receiving angles and a breadth of the scattering intensity peak. The controller (414) estimates a representative droplet size within the cloud using the scattering profile data.
