Condensation Trail
A visible trail of condensed water vapor or ice particles left behind an
aircraft, an airfoil, etc. in motion through the air. Also called a
contrail or vapor trail.
There are three kinds of condensation trails: the aerodynamic type,
caused by reduced pressure of the air in certain areas as it flows past the
aircraft; the convection type, caused by the rising of air warmed by an
engine; and the engine-exhaust, or exhaust-moisture, type, formed by the
ejection of water vapor from an engine into a cold atmosphere.
