Abstract
An aircraft comprises a wing () defining an aerofoil surface, the wing () comprising a drooped leading edge flap () being moveable between a stowed position and a deployed position. The wing () is so arranged that during flight when the high-lift device is in the deployed position, air may flow through an opening () in the wing () and over the aerofoil surface. During flight, air preferably flows into the boundary layer () on the upper surface of the wing (). This energises the boundary layer (), aft of the trailing edge of the drooped leading edge flap increasing its stability allowing the maximum achievable lift coefficient to be increased and hence reducing aircraft take-off and approach speeds.
