Abstract
Apparatus and associated methods relate to measuring metrics of a contrail produced by an aircraft engine. To measure such metrics, a beam of light is projected into a projection volume that intersects an exhaust path of the aircraft engine. Light from a reception volume that intersects the exhaust path of the aircraft engine is received. An intersection volume is formed by an intersection of the reception volume and the projection volume. The light received includes a reflected portion of the projected beam backscattered by the atmosphere from within the intersection volume. The reflected portion of light received is used to determine whether a contrail is forming within the intersection volume. An alert is generated in response to determination that a control is forming within the intersection volume.
