00:01.600 --> 00:03.656
We're out in the mountainous terrain

00:03.656 --> 00:05.711
doing water bucket drops over alpine

00:05.711 --> 00:07.822
lakes . We have an engine failure and

00:07.822 --> 00:09.933
the helicopter ends up going into the

00:09.933 --> 00:11.933
water . What are you going to do in

00:11.933 --> 00:11.819
that instant is that the moment that

00:11.829 --> 00:14.170
you're going to want to have to react

00:14.180 --> 00:16.291
to the situation that you're in or do

00:16.291 --> 00:18.236
you want to go into that situation

00:18.236 --> 00:20.291
prepared ? Today ? We're here in the

00:20.291 --> 00:22.513
Dolphin Scuba center . We're practicing

00:22.513 --> 00:24.791
helicopter emergency underwater egress .

00:24.840 --> 00:27.062
This is a multi stage class . It starts

00:27.062 --> 00:29.284
with a classroom portion where we learn

00:29.284 --> 00:31.451
the basics of breathing off compressed

00:31.451 --> 00:34.549
air , the heats bottles and then some

00:34.560 --> 00:36.727
of the physiological and psychological

00:36.727 --> 00:38.671
traits that we're going to have to

00:38.671 --> 00:40.838
overcome in the event of an over water

00:40.838 --> 00:43.060
emergency . We want to start all of our

00:43.060 --> 00:45.171
students out at a very basic level so

00:45.171 --> 00:47.430
they can develop comfort and

00:47.459 --> 00:49.237
familiarize themselves with the

00:49.237 --> 00:51.348
equipment that they're using over the

00:51.348 --> 00:53.459
water that starts with using the heat

00:53.459 --> 00:55.626
bottles or helicopter emergency egress

00:55.626 --> 00:57.737
device , compressed air cylinder that

00:57.737 --> 00:59.570
they wear on their desk . You'll

00:59.570 --> 01:01.737
activate that . The way we start is by

01:01.737 --> 01:03.903
having students breathe off compressed

01:03.903 --> 01:05.903
air , off a scuba cylinder and then

01:05.903 --> 01:08.070
once they're comfortable breathing off

01:08.070 --> 01:07.910
and clearing a regulator , we'll do

01:07.919 --> 01:09.720
that in burden . Once they're

01:09.730 --> 01:12.250
comfortable doing that upside down as

01:12.260 --> 01:14.427
the crawl stage of the class , we will

01:14.427 --> 01:16.371
move to the walk where we have two

01:16.371 --> 01:18.538
different devices . Here , we have the

01:18.538 --> 01:20.704
sweat chairs and the dunker will to be

01:20.704 --> 01:23.160
strapped into these seats and move

01:23.169 --> 01:25.169
through their paces . So we'll turn

01:25.169 --> 01:27.280
that upside down and they'll practice

01:27.280 --> 01:29.447
making sure their visor is down , that

01:29.447 --> 01:31.502
their concord is disconnected , that

01:31.502 --> 01:33.725
they have a reference point and leasing

01:33.725 --> 01:35.891
their seatbelt when the motions stop .

01:35.891 --> 01:37.947
The goal of this class is increasing

01:37.947 --> 01:40.113
the survivability in the event that we

01:40.113 --> 01:42.280
have an over water engine failure . So

01:42.280 --> 01:44.225
most of the time during helicopter

01:44.225 --> 01:46.447
water bucket operations , we operate in

01:46.447 --> 01:48.558
what's called the HB curve , which is

01:48.558 --> 01:50.447
that we do not have the height or

01:50.447 --> 01:52.669
velocity to get out of that situation .

01:52.669 --> 01:54.891
So in the event that we have to land in

01:54.891 --> 01:57.089
the water in a survivable crash , we

01:57.099 --> 01:59.321
want to make sure that the crew members

01:59.321 --> 02:00.750
are able to get out of that helicopter .
