The prize for HUET must surely go to CASA who have mandated it for aircrew engaged in offshore operations in their
proposed helicopter regulations CASR Part 133.825(4).
(4) The operator of:
(a) a rotorcraft in Performance Class 3 that is engaged in
regular operations beyond 10 nm from land suitable for an
emergency landing; or
(b) a rotorcraft in Performance Class 2 that is engaged in
routine operations to or from a marine HLS or a helideck;
must ensure that crew members engaged in the operations
complete an underwater escape training course not later than 6
months after the commencement of operations.
