An aircraft nacelle comprising a first and a second cowl mounted pivotably about an axis substantially parallel to a longitudinal axis of the nacelle and lockable to one another by at least one locking mechanism. The nacelle further comprises a device for providing a visual warning of a locking defect of the cowls. The device comprises a movable bolt associated with the locking mechanism and a movable edge plate mounted on the nacelle in line with said bolt with which it is associated, the movable edge plate being movable under the action of an operator between a protruding position, in which the edge plate is protruding from the nacelle and a locking mechanism is in an unlocked position, and a retracted position, in which the edge plate is immobilized within the nacelle by the bolt and the action of the locking of a locking mechanism.

1. An aircraft nacelle comprising: a first and a second cowl mounted pivotably about an axis substantially parallel to a longitudinal axis of the nacelle and lockable to one another by at least two locking mechanisms,a device for providing a visual warning of a locking defect of the cowls comprising a movable bolt and a movable edge plate mounted on the nacelle in line with said movable bolt with which the movable edge plate is associated, the movable edge plate being movable under the action of an operator between a protruding position, in which the movable edge plate is protruding from the nacelle, and a retracted position, in which the movable edge plate is immobilized within the nacelle by the movable bolt when each locking mechanism is locked,wherein the movable bolt is coupled to each locking mechanism, andwherein the movable bolt comprises a rod, one control element associated with each locking mechanism, and at least one return member. 2. The aircraft nacelle as claimed in claim 1, wherein each control element comprises a collar mounted movably on the rod and, associated with said collar,a lever mounted in a manner hinged about a pivot axis perpendicular to the rod, a shoulder formed integrally with the rod, and a spring inserted around said rod and positioned between the shoulder and the collar. 3. The nacelle as claimed in claim 2, wherein the collar is cylindrical and is provided with an annular throat defining two annuli at the ends of the collar, the lever comprises a first branch and a second branch, one end of the first branch of the lever is configured to be received in the annular throat between the two annuli, and one end of the second branch of the lever cooperates with one of the at least two locking mechanisms. 4. The nacelle as claimed in claim 1, wherein the rod comprises a stop and is mounted so as to be movable in translation on at least one flange, the return member is inserted around the rod and is arranged between the stop and the flange. 5. The nacelle as claimed in claim 4, wherein the return member comprises a coil spring. 6. The nacelle as claimed in claim 1, wherein the movable edge plate comprises a guide support for guiding a panel and a second return member, the panel being inserted in the guide support. 7. The nacelle as claimed in claim 6, wherein the panel comprises a through-hole intended to accommodate an end of the rod. 8. The nacelle as claimed in claim 6, wherein the panel is painted in a bright color. 9. The nacelle as claimed in claim 8, wherein the panel is painted in one of orange or red. 10. An aircraft nacelle comprising: a first and a second cowl mounted pivotably about an axis substantially parallel to a longitudinal axis of the nacelle and lockable to one another by at least one locking mechanism,a device for providing a visual warning of a locking defect of the cowls comprising a movable bolt and a movable edge plate mounted on the nacelle in line with said movable bolt with which the movable edge plate is associated, the movable edge plate being movable under the action of an operator between a protruding position, in which the movable edge plate is protruding from the nacelle, and a retracted position, in which the movable edge plate is immobilized within the nacelle by the movable bolt when each locking mechanism is locked,wherein the movable bolt is coupled to each locking mechanism, andwherein the movable bolt comprises a rod, one control element associated with each locking mechanism, and at least one return member, wherein each control element comprises a collar mounted movably on the rod and, associated with said collar,a lever mounted in a manner hinged about a pivot axis perpendicular to the rod, a shoulder formed integrally with the rod, and a spring inserted around said rod and positioned between the shoulder and the collar. 11. The nacelle as claimed in claim 10, wherein the rod comprises a stop and is mounted so as to be movable in translation on at least one flange, the return member is inserted around the rod and is arranged between the stop and the flange. 12. The nacelle as claimed in claim 11, wherein the return member comprises a coil spring. 13. The nacelle as claimed in claim 11, wherein the movable edge plate comprises a guide support for guiding a panel and a second return member, the panel being inserted in the guide support. 14. The nacelle as claimed in claim 13, wherein the panel comprises a through-hole intended to accommodate an end of the rod. 15. The nacelle as claimed in claim 13, wherein the panel is painted in a bright color. 16. The nacelle as claimed in claim 15, wherein the panel is painted in one of orange or red. 17. An aircraft nacelle comprising: a first and a second cowl mounted pivotably about an axis substantially parallel to a longitudinal axis of the nacelle and lockable to one another by at least one locking mechanism,a device for providing a visual warning of a locking defect of the cowls comprising a movable bolt and a movable edge plate mounted on the nacelle in line with said movable bolt with which the movable edge plate is associated, the movable edge plate being movable under the action of an operator between a protruding position, in which the movable edge plate is protruding from the nacelle, and a retracted position, in which the movable edge plate is immobilized within the nacelle by the movable bolt when each locking mechanism is locked,wherein the movable bolt is coupled to each locking mechanism, andwherein the movable bolt comprises a rod, one control element associated with each locking mechanism, and at least one return member, wherein each control element comprises a collar mounted movably on the rod and,associated with said collar, a lever mounted in a manner hinged about a pivot axis perpendicular to the rod, a shoulder formed integrally with the rod, and a spring inserted around said rod and positioned between the shoulder and the collar,wherein the collar is cylindrical and is provided with an annular throat defining two annuli at the ends of the collar, the lever comprises a first branch and a second branch, one end of the first branch of the lever is configured to be received in the annular throat between the two annuli, and one end of the second branch of the lever cooperates with the at least one locking mechanism. 18. The nacelle as claimed in claim 17, wherein the rod comprises a stop and is mounted so as to be movable in translation on at least one flange, the return member is inserted around the rod and is arranged between the stop and the flange. 19. The nacelle as claimed in claim 18, wherein the return member comprises a coil spring. 20.
