At low speeds, an aircraft has reduced airflow over the [[wing]] and [[vertical stabiliserstabilizer]]. This causes the [[control surfaces]] ([[ailerons]], [[elevators]] and [[rudder]]) to be less effective. The CCW system increases the airflow over these surfaces and consequently can allow much higher manoeuvrabilitymaneuverability at low speeds.<ref>{{cite web |url=http://www.airspacemag.com/issues/2007/april-may/custer_channel_wing.php?page=2|title=Circulation Control Technology|accessdate=2007-12-15}}</ref> However, if one of the CCW systems should fail at low speed, the affected wing is likely to [[stall (flight)|stall]] which could result in an inescapable [[spin (flight)|spin]]. Finally, the CCW system could be used on multi-engine aircraft in the result of an engine failure to cancel the [[asymmetric forces]] from the loss of power on one wing.<ref>{{cite web |url=http://www.airspacemag.com/issues/2007/april-may/custer_channel_wing.php?page=2|title=Circulation Control Technology|accessdate=2007-12-15}}</ref>
