10. The monument of claim 1, further comprising a fixture secured thereto, wherein the fixture provides a useful mass that facilitates movement into the deployed state when the force that meets or exceeds the predetermined threshold is exerted into the monument.

11. The monument of claim 10, wherein the fixture is secured to a fore surface or an aft surface of a clearance panel.

12. The monument of claim 1, wherein the deployable portion comprises a main body of the monument, and wherein the main body is configured to move from the non-deployed state into the deployed state when the force that meets or exceeds the predetermined threshold is exerted into the monument.

13. The monument of claim 12, wherein the main body is configured to be secured to a portion of the internal cabin through at least one fitting including an anchored portion that connects to the main body through a frangible portion.

14. The monument of claim 12, wherein the main body is configured to be secured to a portion of the internal cabin through at least one fitting including one or more pivot hinges.

15. The monument of claim 12, wherein the main body is configured to pivot forward when the force that meets or exceeds the predetermined threshold is exerted into the monument.

16. The monument of claim 12, further comprising one or more frangible elements located proximate to one or both of floor fittings or ceiling fittings.

17. The monument of claim 1, wherein the one or more bracing members are secured to outer lateral edges of the clearance panel.

18. A vehicle, comprising:

an internal cabin;

a plurality of seats within the internal cabin; and

a monument proximate to at least one of the plurality of seats, wherein the monument includes a deployable portion, wherein the deployable portion is configured to move from a non-deployed state into a deployed state when a force that meets or exceeds a predetermined threshold is exerted into the monument, the deployable portion comprising a deployable clearance panel within a monument wall assembly, the clearance panel being configured to move from the non-deployed state into the deployed state when the force that meets or exceeds a predetermined threshold is exerted into the monument wall assembly, the clearance panel comprising one or more bracing members that prevent the clearance panel from moving from the deployed state back to the non-deployed state, the one or more bracing members pivotally or slidably coupling the clearance panel to a fixed wall, and the one or more bracing members being configured to slide or pivot into an outwardly deployed position that prevents the clearance panel from moving from the deployed state back to the non-deployed state.

19. The vehicle of claim 18, wherein the clearance panel further comprises a first portion pivotally secured to the fixed wall, and a second portion coupled to the fixed wall by at least one shear pin, and wherein the at least one shear pin is configured to break upon exertion of the force that meets or exceeds the predetermined threshold.

20. The vehicle of claim 18, wherein the clearance panel comprises a first portion that is configured to pivotally secure to a floor of the internal cabin, and a second portion that is configured to couple to one of the fixed wall or a ceiling of the internal cabin by at least one shear pin, and wherein the at least one shear pin is configured to break upon exertion of the force that meets or exceeds the predetermined threshold.

21. The vehicle of claim 18, wherein the monument wall assembly further comprises a covering over the clearance panel that conceals the clearance panel in the non-deployed state, wherein the covering is configured to tear proximate to an interface between the clearance panel and the fixed wall as the clearance panel moves from the non-deployed state into the deployed state.

22. The vehicle of claim 18, further comprising a fixture secured thereto, wherein the fixture provides a useful mass that facilitates movement into the deployed state when the force that meets or exceeds the predetermined threshold is exerted into the monument.

23. The vehicle of claim 18, wherein the deployable portion comprises a main body of the monument, and wherein the main body is configured to move from the non-deployed state into the deployed state when the force that meets or exceeds the predetermined threshold is exerted into the monument.
