System and method for controlling contrail formation

Abstract

A system includes an engine of an aircraft, an oil buffer tube disposed on a bottom side of the engine, a valve disposed at or near an end of the oil buffer tube, and a control device. The control device is configured to obtain data indicating at least one operational condition associated with the aircraft or the engine. The control device is also configured to, in response to determining a first operational condition, control the valve to a first position, wherein the valve in the first position directs oil buffer air to an exhaust of the engine. The control device is also configured to, in response to determining a second operational condition, control the valve to a second position, wherein the valve in the second position directs the oil buffer air away from the exhaust of the engine.
