A wing for an aircraft including a fixed wing and a high-lift device movable between a retracted position and an extended position. The high-lift device includes a movable fence. The fence is movable between a first position in which the fence does not protrude beyond an outer surface of the high-lift device and a second position in which the fence protrudes beyond the outer surface of the high-lift device. The fence is in the first position when the high-lift device is in the retracted position and in the second position when the high-lift device is in the extended position. Further, an aircraft with such a wing, a high-lift device and a fence as well as use of a high-lift device and a fence are provided.

A stabilization system for an aircraft includes a rear stabilizer system. The rear stabilizer system is disposed in a rear portion of the fuselage of the aircraft. The rear stabilizer system includes a rear rudder having a tilt fan configured to generate lift. The rear stabilizer system is configured to detect a failure of an engine and activate an emergency mode. The instructions when executed cause the system to receive flight dynamics from an onboard sensor; determine an existence and a location of the engine failure; and send a signal to the rear rudder based on the existence and the location of the engine failure. The rear rudder engages in a first position. The first position generates counter-torque propulsion towards the engine that failed.

A wing of an aircraft that includes a wing leading edge, a wing trailing edge, and a wing surface defined by a wing upper surface and a wing lower surface is described herein. The wing extends from the wing root to the wingtip, and the wingtip has a wingtip chord. A winglet extends from the wingtip and has a winglet leading edge, a winglet trailing edge, a winglet inboard surface, a winglet outboard surface, a winglet root having a winglet root chord, and a winglet tip. A flow fence is disposed on the wing surface inboard from the winglet and overlapping with the winglet. The flow fence is adapted to delay and/or prevent airflow separation on the winglet inboard surface at high angle of sideslip, increasing lateral stability and linearizing aircraft behavior at high angle of sideslip.
