A thrust reverser system for a turbine engine, comprising: a support structure configured to be mounted to the engine; a transcowl mounted on the support structure and comprising a circumferential front edge, the transcowl movable between a first position, in which the front edge substantially abuts the support structure, and a second position, in which an aperture is formed between the front edge and the support structure to redirect engine airflow, the transcowl comprising the qualities of (i) a continuous structure, and (ii) a predetermined flexibility; a primary locking system comprising a first lock and a second lock, the first and second lock configured to cooperatively lock the front edge to the support structure only when the transcowl is in the first position, the first lock coupled to the front edge at a first location and the second lock coupled to the front edge at a second location, the second location being different than the first location; a secondary locking system coupled to the support structure and comprising a third lock, the third lock coupled at a third location on the front edge, the third lock configured to lock the front edge to the support structure only when (i) the transcowl is in the first position, and (ii) a separation distance between the front edge and the support structure is a secondary gap distance that is greater than a first gap distance reflecting deflection, the secondary gap distance representing an amount of travel aft that implies that all locks in the primary locking system have failed; and a system for monitoring a transcowl thrust reverser comprising a first sensor located proximate the first lock, a second sensor located proximate the second lock, wherein the first and second sensors are each configured to, when the transcowl is in the first position, detect a respective separation distance between the front edge and the support structure, a sensor module coupled to the first and second sensors, and configured to process respective separation distances and a first gap distance to determine (i) when the first lock has failed, and (ii) when the second lock has failed. a support structure configured to be mounted to the engine; a transcowl mounted on the support structure and comprising a circumferential front edge, the transcowl movable between a first position, in which the front edge substantially abuts the support structure, and a second position, in which an aperture is formed between the front edge and the support structure to redirect engine airflow, the transcowl comprising the qualities of (i) a continuous structure, and (ii) a predetermined flexibility; a primary locking system comprising a first lock and a second lock, the first and second lock configured to cooperatively lock the front edge to the support structure only when the transcowl is in the first position, the first lock coupled to the front edge at a first location and the second lock coupled to the front edge at a second location, the second location being different than the first location; a secondary locking system coupled to the support structure and comprising a third lock, the third lock coupled at a third location on the front edge, the third lock configured to lock the front edge to the support structure only when (i) the transcowl is in the first position, and (ii) a separation distance between the front edge and the support structure is a secondary gap distance that is greater than a first gap distance reflecting deflection, the secondary gap distance representing an amount of travel aft that implies that all locks in the primary locking system have failed; and a system for monitoring a transcowl thrust reverser comprising a first sensor located proximate the first lock, a second sensor located proximate the second lock, wherein the first and second sensors are each configured to, when the transcowl is in the first position, detect a respective separation distance between the front edge and the support structure, a sensor module coupled to the first and second sensors, and configured to process respective separation distances and a first gap distance to determine (i) when the first lock has failed, and (ii) when the second lock has failed. a first sensor located proximate the first lock, a second sensor located proximate the second lock, wherein the first and second sensors are each configured to, when the transcowl is in the first position, detect a respective separation distance between the front edge and the support structure, a sensor module coupled to the first and second sensors, and configured to process respective separation distances and a first gap distance to determine (i) when the first lock has failed, and (ii) when the second lock has failed.
