CLAIMS:

What is claimed is:

1. An apparatus comprising:

a structure (330) configured for connection to a hinge (328) for a door (308) in an aircraft (200); and

an extended portion (332) in the structure (330) configured to reduce a width (324) of a doorway (302) in which the door (308) is located when the door (308) is in a substantially open position (334).

2. The apparatus of claim 1, wherein the structure (330) is configured to be removably connected to the hinge (328).

3. The apparatus of claim 1, wherein the structure (330) comprises a fairing that covers at least a portion of the hinge (328).

4. The apparatus of claim 1, wherein the structure (330) comprises a fairing that covers at least a portion of the hinge (328) and the extended portion (332) comprises a member associated with the fairing.

5. The apparatus of claim 1, wherein the hinge (328) is located on a first side of the doorway (302) and wherein the structure (330) is in line with the doorway (302) and positioned a selected distance from a second side of the doorway (302) such that a first distance of the structure (330) from the second side of the doorway (302) is less than a second distance from the first side to the second side.

6. The apparatus of claim 1, wherein the structure (330) reduces the width (324) of the doorway (302) when the door (308) is in an open position (320) to allow for an exit of passengers through the doorway (302) one at a time.

7. An apparatus comprising:

a structure (330) configured to be connected to a door system in a vehicle; and

an extended portion (332) in the structure (330) configured to reduce a width (324) of a doorway (302) in which the door system is located when the door system is in an open position (320).

8. The apparatus of claim 7, wherein the structure (330) is configured to be removably connected to a hinge (328).

9. The apparatus of claim 7, wherein the door system comprises:

a door (308); and

the hinge (328) connecting the door (308) to a body of the vehicle.

10. The apparatus of claim 9, wherein the structure (330) comprises a fairing that covers at least a portion of the hinge (328).

11. The apparatus of claim 8, wherein the structure (330) comprises a member configured to be associated with at least one of a door (308) and the hinge (328).

12. The apparatus of claim 8, wherein the hinge (328) is located on a first side of the doorway (302) and wherein the structure (330) is in line with the doorway (302) and positioned a selected distance from a second side of the doorway (302) such that a first distance of the structure (330) from the second side of the doorway (302) is less than a second distance from the first side to the second side.

13. The apparatus of claim 9, wherein the structure (330) reduces the width (324) of the doorway (302) when the door (308) is in the open position (320) to allow for an exit of passengers through the doorway (302) one at a time.

14. The apparatus of claim 7, wherein the vehicle is selected from one of an aircraft (200), a ship, a spacecraft, and a train.

15. A method for managing access to an aircraft (200), the method comprising:

identifying a door (308) in a doorway (302) to be opened, wherein the door (308) is connected to a wall (304) of the aircraft (200) by a hinge (328) and a structure (330) associated with the hinge (328) and has an extended portion (332); and

moving the door (308) to an open position (320), wherein the hinge (328) with the structure (330) moves such that the extended portion (332) in the structure (330) reduces a width (324) of the doorway (302) to a desired width (324) when the door (308) is in the open position (320).

16. The method of claim 15 further comprising:

moving objects through the doorway (302).

17. The method of claim 15, wherein the structure (330) is configured to be removably connected to the hinge (328).

18. The method of claim 15, wherein the structure (330) comprises a fairing that covers at least a portion of the hinge (328).

19. The method of claim 15, wherein the structure (330) comprises a member configured to be associated with the hinge (328).

20. The method of claim 15, wherein the hinge (328) is located on a first side of the doorway (302) and wherein the structure (330) is in line with the doorway (302) and positioned a selected distance from a second side of the doorway (302) such that a first distance of the structure (330) from the second side of the doorway (302) is less than a second distance from the first side to the second side.
