1. An aircraft location system comprising:
- a signal location system;
an aircraft structure that comprises;
an acoustic reflector configured to receive, in a water environment, a sound signal, from the signal location system, and reflect, into the water environment, an echo of the sound signal;
a signal generator associated with the aircraft structure;
a detector configured to receive the echo, and associated with a controller, the controller connected to the signal generator, and configured such that in operation, in response to receipt of the echo, the controller activates the signal generator; and
the signal generator being connected to a light and configured such that in operation the light generates light signals in response to being activated by the controller after the detector receives the echo.

13. An aircraft location system that comprises:
-
a signal location system; a first aircraft structure that comprises a first signal system and one of;
a fuselage, and a tail section, such that the first signal system comprises;a first detector; a first acoustic reflector configured to receive, in a water environment, sound signals from the signal location system, and reflect, to the first detector, in the water environment, first echoes of the sound signals; a first controller connected to and configured to activate, for a period of time less than a life of a battery of a first number of signal generators associated with the first aircraft structure, and based upon receipt of the first echoes by the first detector, the first number of signal generators; and a second aircraft structure comprising a wing, and a second signal system that comprises; a second detector; a second acoustic reflector configured to receive, in the water environment, the sound signals from the signal location system, and reflect, second to the second detector, in the water environment, second echoes of the sound signals; and a second controller connected to and configured to activate, for a period of time less than a life of a battery of a second number of signal generators associated with the second aircraft structure, and based upon receipt of the second echoes by the second detector the second number of signal generators. - View Dependent Claims (14, 15, 16, 17, 19)
