A latch includes a first locking bolt, where a first extended position of the first locking bolt defines a first locked condition and a first retracted position defines a first unlocked condition. The latch also includes a second locking bolt, where a second extended position of the second locking bolt defines a second locked condition and a second retracted position defines a second unlocked condition. A biasing member operatively connects to the first locking bolt to bias the first locking bolt in the first extended position. A lever pivotally connects to the housing and operatively connects to the first locking bolt such that movement of the lever from a closed position to an opened position causes at least the first locking bolt to move from the first extended position to the first retracted position. A locking indicator is provided in associated with the second locking bolt.

The latch of claim 3, further comprising: a housing containing the first, biased locking bolt and the second, unbiased locking bolt. 5. The latch of claim 4, wherein a biasing member is connected between the first, biased locking bolt and the housing. 6. The latch of claim 4, wherein the first, biased locking bolt extends through the housing when in the first, extended position and the second, unbiased locking end extends through the housing when in the second, extended position. 7. The latch of claim 4, wherein the housing is cup shaped. 8. The latch of claim 1, further comprising: a biasing member connected to the first, biased locking bolt to bias the first, biased locking bolt into the first, extended position. 9. The latch of claim 8, wherein the biasing member is a spring. 10. The latch of claim 8, wherein release of the actuation device from the second position permits the biasing member to return the first, biased locking bolt to the first, extended position. 11. The latch of claim 1, wherein the locking indicator is visible when the second, unbiased locking bolt is in the second, retracted position. 12. The latch of claim 11, wherein the second, unbiased locking bolt comprises a locking end and an interior end, the locking indicator being disposed on the interior end. 13. The latch of claim 1, wherein the first position of the actuation device is a closed position and the second position of the actuation device is an opened position of the lever. 14. The latch of claim 13, wherein the lever conceals the locking indicator disposed on the second, unbiased locking bolt when the second, unbiased locking bolt is in the second, extended position and the lever is in the closed position. 15. The latch of claim 14, wherein the locking indicator is revealed from beneath the lever when the second, unbiased locking bolt is in the second, retracted position and the lever is in the closed position. 16. The latch of claim 1, wherein the actuation device comprises the lever connected to the second, unbiased locking bolt and a second lever connected to the first, biased locking bolt. 17. The latch of claim 1, wherein the first, biased locking bolt and the second, unbiased locking bolt are disposed adjacent to one another in a substantially parallel relationship. 18. An aircraft storage compartment, comprising: a frame;a door; anda latch for releasably securing the door to the frame in a closed position, the latch comprising: a first, biased locking bolt movable between a first, extended position and a first, retracted position, wherein the first, biased locking bolt is biased into the first, extended position;a second, unbiased locking bolt movable between a second, extended position and a second, retracted position, wherein the second, unbiased locking bolt is able to remain in the second, retracted position while the first, biased locking bolt is biased into the first, extended position; andan actuation device operatively connected to both the first, biased locking bolt and the second, unbiased locking bolt such that when the first, biased locking bolt is in the first, extended position and the second, unbiased locking bolt is in the second, extended position for securing the door to the frame, actuation of the actuation device from a first position to a second position moves both the first, biased locking bolt into the first, retracted position and the second, unbiased locking bolt into the second, retracted position for enabling opening of the door in relation to the frame,wherein a locking indicator is disposed on the second, unbiased locking bolt, the locking indicator being concealed by a lever of the actuation device when the second, unbiased locking bolt is in the second, extended position and the actuation device is in the first position. 19. A method of operating a latch comprising a first, biased locking bolt movable between a first, extended position and a first, retracted position, wherein the first, biased locking bolt is biased into the first, extended position; a second, unbiased locking bolt movable between a second, extended position and a second, retracted position wherein the second, unbiased locking bolt is able to remain in the second, retracted position while the first, biased locking bolt is biased into the first, extended position; and an actuation device operatively connected to both the first, biased locking bolt and the second, unbiased locking bolt such that actuation of the actuation device from a first position to a second position moves both the first, biased locking bolt into the first, retracted position and the second, unbiased locking bolt into the second, retracted position, wherein a locking indicator is disposed on the second, unbiased locking bolt, the locking indicator being concealed by a lever of the actuation device when the second, unbiased locking bolt is in the second, extended position and the actuation device is in the first position, wherein the method comprises: manipulating the actuation device from the first position to the second position;by operation of the actuation device to the second position, retracting the first, biased locking bolt from the first, extended position to the first, retracted position and also retracting the second, unbiased locking bolt from the second, extended position to the second, retracted position; andreleasing the actuation device, permitting the first, biased locking bolt to return to the first, extended position while the second, unbiased locking bolt remains in the second, retracted position. 20.
