An operation managing system is provided for managing the operation of a navigation control device. The navigation control device is adapted for controlling the depth and/or the lateral position of a towed acoustic linear antenna and including a body to which is attached a set of wings. The operation managing system operates the navigation control device according to a degraded operating mode, by acting on at least one non-released and motorized wing when detecting that at least one wing of the set of wings has been released or must be released.

A wing releasing system is provided for releasing at least one wing of a set of wing or wings of a navigation control device. The navigation control device is adapted for controlling depth and/or lateral position of a towed acoustic linear antenna and includes a body to which is attached the set of wing or wings. The wing releasing system includes: a releasing decision circuit, for generating a release request signal when detecting that a foreign object is caught by at least one wing of the set of wing or wings; and an actuator comprised in the navigation control device, for releasing from the body the at least one wing of the set of wing or wings, when receiving the release request signal.
