Platform

1. A method of operating in an aircraft wing rib bay, comprising the steps of:

providing a rib bay platform of adjustable length;

adjusting the length of the platform so as to match the distance between two stringers located on the respective internal surfaces on either side of the rib bay;

mounting the platform between the two stringers whereby a person may then operate inside the aircraft rib bay whilst being supported on the platform; and

adjusting the horizontal orientation of the rib bay platform by means of adjustment of the height of at least one end of the platform in relation to a corresponding stringer on which it is supported.

2. A method according to claim 1 , wherein the method comprises a step of grippingly mounting one end of the platform on one of the two stringers.

3. A method according to claim 2 comprising the step of extending the platform, once so mounted, towards the other stringer.

4. A method according to claim 1 , comprising the steps of:

providing a second platform of adjustable length;

adjusting the length of the second platform so as to match the distance between two stringers located on either side of the rib bay; and

mounting the second platform between the two stringers.

5. A method according to claim 4 , wherein the second platform is mounted at a different location along the chord and span of the wing from the other platform, thereby forming a tiered arrangement of platforms.

6. A method according to claim 4 , wherein the second platform is mounted at the same chordwise location in the rib bay as the other platform.

7. An aircraft wing rib bay comprising a first stringer on one internal surface, a second stringer located on an opposite internal surface, and a rib bay platform of adjustable length mounted between the first and second stringers, wherein said rib bay platform is adjustable in length and comprises:

a first end of said platform configured for mounting on said first stringer of the rib bay,

a second end of said platform configured for mounting on said second stringer of the rib bay, and

a foot located at the second end, the foot adjustable in height with respect to the platform and thereby allowing the platform to be adjusted in the horizontal plane.

8. An aircraft rib bay according to claim 7 , wherein the first end is configured for grippingly mounting on the first stringer.

9. An aircraft rib bay according to claim 7 , wherein the first end is configured for mounting around the first stringer so as to resist relative rotation between the first end of the platform and the first stringer, about an axis parallel to the length of the platform.

10. An aircraft rib bay according to claim 7 , wherein the first end is configured so as to form an interference fit with the first stringer.

11. An aircraft rib bay according to claim 7 , wherein the width of the first end is over 80% of the width of the platform.

12. An aircraft rib bay according to claim 7 , wherein the second end is configured to rest on the second stringer.

13. An aircraft rib bay according to claim 12 , said platform including a plurality of feet located at the second end, the outermost feet being separated by a distance of at least 80% of the width of the platform.

14. An aircraft rib bay according to claim 12 , wherein at least one foot is arranged to conform to the shape of the stringer.

15. An aircraft rib bay according to claim 7 , wherein the platform comprises a plurality of platform sections slideably mounted for relative movement in a direction along the length of the platform.

16. An aircraft rib bay according to claim 15 , wherein the platform sections are telescopically mounted.

17. An aircraft rib bay according to claim 7 , wherein the platform further includes a locking mechanism for preventing adjustment of the length of the platform.
