| Helicopters are a
very safe and efficient means of transporting to and from offshore locations,
but like any man made device, they are prone to failure. As the number of
personnel flying over water increases, there is a greater risk of helicopter
ditchings and the need for personnel to be trained in underwater escape
methods. This video outlines the actions required by passengers during a
a controlled ditching (autorotation to an upright position), a semi-controlled
ditching (autorotation with immediate capsizing) and an uncontrolled ditching
(mid-flight break up or hard entry into the water). Emphasis is placed on
preflight preparation, listening to the flight crew, use of seat belt, knowledge
of proper crash positions, and the ability of passengers to orient themselves
underwater in order to locate and activate submerged aircraft exits. (20

...Once you have
been notified of an emergency landing procedure, you may only have moments
to prepare yourself It is very unusual for passengers to have more than
one to two minutes of warning, and most of the time you'll have less than
15 seconds.
It won't do any good to start asking questions on what you should do once
the call for ditching goes out. Your best defensive action is good pre-flight
training and good in-flight preparation.
If ditching is imminent and little or no
warning is possible, you should immediately get into a crash position.
Those who do not brace are much more likely to perish upon impact, a fact
evidenced by the recent study of numerous crash sites.
However, if there is advanced warning with time to prepare for ditching,
begin by tightening your seat belt. Remove and secure any sharp or loose
objects such as glasses, dentures, pen in the pocket, hard hat, or a briefcase
laying loose in the cabin. Don your immersion suit hood or a wool hat,
and if available place a diver's face mask over your eyes and nose.
Assume the crash position. Brace your body
for impact by bending over, arching the spine with your chest on your
thighs, and wrapping your arm closest to your primary exit tightly under
your thighs for protection. With the other hand, grab the leg of the chair
or seat itself. Brace your feet firmly on the floor, slightly apart.
If your are unable to bend completely over due to an obstruction in from
of your seat, assume the alternative crash position. Cradle your head
with one arm and then brace it against the seat or any structure ahead
of your to prevent movement. Hold onto the seat with your other arm.
The adoption of a good crash position can
increase your rate of survival in several ways...
