Not quite. One first has to get within a reasonable range of the source, and they have
not yet found the debris they
think is from the plane, nor yet had a shot at working from that location (presuming they find it) back along the best calculated wind/surface current movement track to a reasonable first search datum. Once that's sorted, then a sensor can be lowered into the ocean to try and hear the ping.
Let's not put the cart before the horse.
