Hi,
It (the primary(?) ELT) went to the bottom of the Equtorial Atlantic with the rest of the wreckage. As it got to greater depths the bits that had airpockets were crushed. That's what happened to it.
the moment the antenna becomes submerged it is ineffective.
This not supposed to be a
floating device ?
And if this floating device is
inside the aircraft ... it's another utter non-sens ...
For the Airbus ... better to put it on the exterior of the vertical stabilizer .. it's the only part of this aircraft who always float after a crash at sea .......
Otherwise .. it's plenty auto- release systems working by hydrostatic press ... maybe it's too much sophisticated for the aviation world ?? .. but it work great in the naval world ......
