1. A system for monitoring a state of a two-part-cowl lock, the lock comprising a plurality of lock units, the plurality of lock units comprising a main lock unit and one or more normal lock units, and the system comprising: a rod for each of the plurality of lock units, the rod of each of the plurality of lock units being mechanically connected to a corresponding pair hook-keeper, each of which have a hook and a keeper, of a respective one of the plurality of lock units;a spring for each of the plurality of lock units, the spring of each of the plurality of lock units being mechanically coupled to the rod of a respective one of the plurality of lock units so that an extended state of the spring corresponds to a first position of the rod of the respective one of the plurality of lock units, and a compressed state of the spring corresponds to a second position of the rod of the respective one of the plurality of lock units; anda warning mechanism configured to be operated by any of the rods to warn of the state of the two-part-cowl lock, the warning mechanism comprising: a tilting piece for each of the one or more normal lock units;a main tilting piece for the main lock unit;a transmitting rod for each of the one or more normal lock units, each transmitting rod connecting the tilting piece of a respective one of the one or more normal lock units to a tilting piece of a next one of the one or more normal lock units or to the main tilting piece;a main cable configured to connect the main tilting piece with a main lock configured to hold and release a flap; anda main spring configured to set the main tilting piece at a resting position against a stop when no force is exerted on the main tilting piece,wherein the main tilting piece comprises at least first, second, and third portions, the first portion being attached to the transmitting rod of one of the one or more normal lock units, the second portion being configured to mechanically interface with the rod of the main lock unit, and the third portion being fixedly connected to the main cable, andwherein the main cable is movably linked to the rod of each of the plurality of lock units so that, when each rod is in the second position, the main cable is in a rest state and all rods of the plurality of lock units are positioned so as to not exert an actuating force on the tilting pieces or the main tilting piece to indicate the lock is in a locked state, and, when one or more rod is in the first position, the main cable is in a pulled state due to contact the one or more rod with one of the tilting pieces and/or the main tilting piece, so that each tilting piece and the main tilting piece are each in an actuated position to indicate the lock is in an unlocked state,wherein the system is configured such that, when the main tilting piece moves from the actuated position to the resting position, the main cable automatically moves from the pulled state to the rest state. 2. The system according to claim 1, wherein: when the rod of one or more of the plurality of lock units is in the first position, the keeper of each of the one or more of the plurality of lock units is not positioned to engage with the hook; andwhen the rod of one or more of the plurality of lock units is in the second position, the keeper of each of the one or more of the plurality of lock units is positioned to engage with the hook. 3. The system of claim 1, comprising an additional warning mechanism for each of the plurality of lock units, wherein each additional warning mechanism comprises a proximity sensor and a target configured for detection by the proximity sensor, wherein the target is attached to the rod of a corresponding one of the plurality of lock units to indicate the state of the one or more of the plurality of lock units. 4. The system of claim 1, wherein the rest state of the main cable corresponds to a closed state of the flap and the pulled state of the main cable corresponds to an open state of the flap. 5. The system of claim 1, comprising an additional warning mechanism for one or more of the plurality of lock units, wherein each additional warning mechanism comprises a proximity sensor and a target configured for detection by the proximity sensor, wherein the target is attached to the rod of a corresponding one of the one or more of the plurality of lock units to indicate the state of the one or more of the plurality of lock units. 6. An aircraft comprising at least one system for monitoring a state of a two-part-cowl lock, the lock comprising a plurality of lock units comprising a main lock unit and one or more normal lock units, and the system comprising: a rod for each of the plurality of lock units, the rod of each of the plurality of lock units being mechanically connected to a corresponding pair hook-keeper, each of which have a hook and a keeper, of a respective one of the plurality of lock units;a spring for each of the plurality of lock units, the spring of each of the plurality of lock units being mechanically coupled to the rod of a respective one of the plurality of lock units so that an extended state of the spring corresponds to a first position of the rod of the respective one of the plurality of lock units, and a compressed state of the spring corresponds to a second position of the rod of the respective one of the plurality of lock units;a warning mechanism configured to be operated by any of the rods to warn of the state of the two-part-cowl lock, the warning mechanism comprising: a tilting piece for each of the one or more normal lock units;a main tilting piece for the main lock unit;a transmitting rod for each of the one or more normal lock units, each transmitting rod connecting the tilting piece of a respective one of the one or more normal lock units to a tilting piece of a next one of the one or more normal lock units or to the main tilting piece;a main cable configured to connect the main tilting piece with a main lock configured to hold and release a flap; anda main spring configured to set the main tilting piece at a resting position against a stop when no force is exerted on the main tilting piece,wherein the main tilting piece comprises at least first, second, and third portions, the first portion being attached to the transmitting rod of one of the one or more normal lock units, the second portion being configured to mechanically interface with the rod of the main lock unit, and the third portion being fixedly connected to the main cable, andwherein the main cable is movably linked to the rod of each of the plurality of lock units so that, when each rod is in the second position, the main cable is in a rest state and all rods of the plurality of lock units are positioned so as to not exert an actuating force on the tilting pieces or the main tilting piece to indicate the lock is in a locked state, and, when one or more rod is in the first position, the main cable is in a pulled state due to contact the one or more rod with one of the tilting pieces and/or the main tilting piece, so that each tilting piece and the main tilting piece are each in an actuated position to indicate the lock is in an unlocked state,wherein the system is configured such that, when the main tilting piece moves from the actuated position to the resting position, the main cable automatically moves from the pulled state to the rest state. 7. The system of claim 6, wherein the rest state of the main cable corresponds to a closed state of the flap and the pulled state of the main cable corresponds to an open state of the flap. 8. The aircraft of claim 6, wherein the system comprises an additional warning mechanism for one or more of the plurality of lock units, wherein each additional warning mechanism comprises a proximity sensor and a target configured for detection by the proximity sensor, wherein the target is attached to the rod of a corresponding one of the one or more of the plurality of lock units to indicate the state of the one or more of the plurality of lock units. 9.
