The present invention relates to a wing tip extension (7) for a wing, having an upper and a lower surface (10and11) and a leading edge and a trailing edge (12and13), the geometries of which are such that between a connection region (8), for connection with a wing, and the tip (9) of the wing tip ext
The present invention relates to a wing tip extension (7) for a wing, having an upper and a lower surface (10and11) and a leading edge and a trailing edge (12and13), the geometries of which are such that between a connection region (8), for connection with a wing, and the tip (9) of the wing tip extension (7) there is provided a continuous increase of the local dihedral, a continuous increase both of the sweepback angle of the leading edge (12) and also of the trailing edge (13), and a continuous decrease of the chord of the wing tip extension (7), and in that the wing tip extension (7) in the connection region (8) carries on from the wing in substance continuously. The wing tip extension (7) in accordance with the invention thereby ensures a significant reduction of the overall drag.

The apparatus of claim 1 wherein the walkway includes a floor portion and wherein the restriction is movable between a deployed position and a stowed position, the restriction being at least partially housed in the floor portion of the walkway when in the stowed position.3. The apparatus of claim 1 wherein the walkway includes a floor portion having a recess and wherein the restriction includes a first upright member, a second upright member, and a handrail pivotably coupled between the first and second upright members, wherein each upright member is pivotably coupled to the floor portion and is pivotable between a deployed position with the upright member generally upright and a stowed position with the upright member at least partially recessed in the floor portion.4. The apparatus of claim 1 wherein the walkway includes a floor portion, two spaced apart wall portions extending upwardly from the floor portion, and a ceiling portion extending from the wall portions over at least part of the floor portion.5. The apparatus of claim 1 wherein the walkway includes a generally planar ramp.6. The apparatus of claim 1 wherein the walkway includes a plurality of stairs extending along the longitudinal axis.7. The apparatus of claim 1 wherein the restriction includes a generally planar flexible sheet wound on a roller and movable relative to the roller between a deployed position with the sheet at least partially unwound from the roller, and a stowed position with the sheet at least partially wound on the roller.8. The apparatus of claim 1 wherein the second portion of the walkway is configured to be attached to an airport terminal structure.9. The apparatus of claim 1 wherein the walkway includes a staircase and wherein the second portion of the walkway is configured to be positioned at or near ground level.10. The apparatus of claim 1 wherein the restriction includes a first upright member, a second upright member spaced apart from the first upright member, and a transverse member extending between the first and second upright members.11. The apparatus of claim 1 wherein the restriction includes a first upright member, a second upright member, and a handrail extending between the first and second upright members, further wherein the restriction includes an extension extending away from both the first and second upright members along the longitudinal axis.12. The apparatus of claim 1 wherein the restriction is segmented and includes a first segment and a second segment, with each of the first and second segments being independently movable relative to the walkway between a deployed position in which the segments at least restrict movement by people between the first and second aisles, and a stowed position in which the segments allow movement by people between the first and second aisles.13. The apparatus of claim 1 wherein the restriction includes a reel and a flexible, coilable, elongated barrier extendibly coiled on the reel.14. The apparatus of claim 1 wherein the restriction includes a plurality of spaced apart, upright members positioned along the longitudinal axis with the upright members spaced sufficiently close together to at least restrict movement by people between the first and second aisles.15. The apparatus of claim 1 wherein the walkway includes a floor portion and wherein the restriction includes a plurality of spaced apart, upright members, with each upright member being movable relative to the floor portion between a deployed position and a stowed position, each upright member being at least partially stowed in the floor when in the stowed position
