Wingtip vortices can pose a hazard to aircraft, especially during the landing and takeoff phases of flight. The intensity or strength of the vortex is a function of aircraft size, speed, and configuration (flap setting, etc.). The strongest vortices are produced by heavy aircraft, flying slowly, with wing flaps and landing gear retracted ...
Wingtip devices help prevent the flow around the wingtip of higher pressure air under the wing flowing to the lower pressure surface on top at the wingtip, which results in a vortex caused by the forward motion of the aircraft. Winglets also reduce the lift-induced drag caused by wingtip vortices and improve lift-to-drag ratio.
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: Squared-off; Aluminium tube bow; Rounded; Hoerner style; Winglets; Drooped tips; Raked ...
Aircraft may have additional minor aerodynamic surfaces. Some of these are treated as part of the overall wing configuration: Winglet: a small fin at the wingtip, usually turned upwards. Reduces the size of vortices shed by the wingtip, and hence also tip drag. Strake: a small surface, typically longer than it is wide and mounted on the ...
Therefore, aircraft operating at altitudes greater than 600 m (2,000 ft) are considered to be at less risk. [3] When the vortices of larger aircraft sink close to the ground — within 100–200 ft (30–61 m) — they tend to move laterally over the ground at a speed of 2–3 kn (3.7–5.6 km/h; 2.3–3.5 mph).
Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.

Outboard tail. An outboard tail is located outboard of the main wing tips. Although sometimes described as tailless, the outboard tail configuration differs from a tailless wing in that the horizontal stabilizer is discontinuous from the main wing surface, typically being set further back and requiring a short boom to support it.
