00:00:00.160 --> 00:00:06.319
whenever you get on a plane you probably picture the captain as a seasoned pro

00:00:04.400 --> 00:00:11.120
with years of experience who will have your aircraft solidly under control at

00:00:08.639 --> 00:00:15.200
all times and in most cases you wouldn't be wrong except that the captain might

00:00:13.200 --> 00:00:19.039
not actually be flying the plane wait a minute what well there's a tremendous

00:00:17.359 --> 00:00:23.359
level of automation that goes into modern jetliners from redundant safety

00:00:21.279 --> 00:00:27.599
systems that kick in automatically to fly-by-wire controls that don't directly

00:00:25.519 --> 00:00:31.760
connect to the plane's control surfaces these turn the yoke into something less

00:00:29.599 --> 00:00:35.840
like a steering wheel and more like an xbox controller and prevent the plane

00:00:33.920 --> 00:00:39.280
from making maneuvers the system deems too dangerous but even aside from all

00:00:37.920 --> 00:00:44.559
this you may have heard that modern planes can basically fly themselves and

00:00:42.000 --> 00:00:48.719
to a large extent this is kind of true you see after the plane takes off a

00:00:46.239 --> 00:00:52.879
computerized autopilot will usually take over it works by linking to sensors

00:00:51.039 --> 00:00:57.760
attached to the aircraft that track everything altitude wind speed direction

00:00:55.920 --> 00:01:01.680
how much the aircraft is banking or if there's turbulence it's kind of like an

00:00:59.600 --> 00:01:05.600
airborne version of lane assist features on newer semi-autonomous cars

00:01:03.520 --> 00:01:09.439
additionally most modern airliners have a computer called a flight management

00:01:07.680 --> 00:01:13.439
system which allows the pilot to enter a flight plan before taking off which

00:01:11.600 --> 00:01:16.799
includes the destination airport as well as which waypoints the plane should

00:01:14.960 --> 00:01:19.680
reach on the way so after takeoff the autopilot will take all of this

00:01:18.080 --> 00:01:23.680
information and control the plane's speed pitch and direction by quickly

00:01:22.000 --> 00:01:28.080
calculating how to safely move the plane's control surfaces with no input

00:01:26.080 --> 00:01:31.840
from the human pilot required and if air traffic control needs the captain to

00:01:29.680 --> 00:01:35.920
make changes in flight the autopilot can help with that too for example to change

00:01:33.759 --> 00:01:39.840
the aircraft's heading or direction all the captain has to do in many cases is

00:01:37.680 --> 00:01:44.159
to turn a knob to the desired heading and the plane will turn itself newer

00:01:42.320 --> 00:01:47.360
planes can even land themselves using the same information and while the

00:01:45.759 --> 00:01:52.960
thought of rapidly approaching the ground under the control of a machine is

00:01:50.640 --> 00:01:57.119
a little scary the idea is that this kind of automation actually makes planes

00:01:55.040 --> 00:02:00.799
safer decisions about how the plane should maneuver can be made more quickly

00:01:58.960 --> 00:02:04.960
and with more precision than if a human pilot had to manually fly the entire

00:02:02.880 --> 00:02:09.599
time in fact some people have said that they can feel that a plane ride gets

00:02:06.799 --> 00:02:14.319
bumpier when a pilot is flying manually and of course fatigue is a real factor

00:02:12.480 --> 00:02:19.599
think about how easy it is to zone out on a half hour drive now imagine doing

00:02:16.800 --> 00:02:25.520
that on a 12 hour flight six miles off the ground hi karumba however autopilots

00:02:23.440 --> 00:02:29.520
aren't perfect obviously they can't react to most emergency situations or

00:02:27.760 --> 00:02:33.200
make unexpected adjustments that responsibility still falls on the

00:02:31.360 --> 00:02:36.319
captain who is required to monitor what the autopilot is doing and make sure

00:02:35.120 --> 00:02:40.879
it's carrying out the correct instructions many pilots don't think of

00:02:38.480 --> 00:02:46.160
an autopilot as an entity that flies the plane rather the human pilots still fly

00:02:43.440 --> 00:02:49.519
the plane through an automated system and despite the high levels of

00:02:47.440 --> 00:02:53.280
automation part of the reason jet pilots still have to go through thousands of

00:02:51.200 --> 00:02:56.879
hours of training and flight time is that they need to understand if a

00:02:54.800 --> 00:03:01.280
miscommunication between the autopilot and the captain's intention is happening

00:02:59.200 --> 00:03:06.080
for example the recent crashes of a pair of new boeing 737s appear to be related

00:03:03.680 --> 00:03:10.159
to an issue where an automated system pushed the plane nose down because it

00:03:08.239 --> 00:03:13.920
misread sensor data about the plane's angle of attack leading the system to

00:03:12.159 --> 00:03:19.040
possibly think the plane was about to stall and in 2013 the well-publicized crash

00:03:17.360 --> 00:03:22.879
landing of an asiana flight in san francisco was determined to be the

00:03:20.560 --> 00:03:26.879
result of a pilot misunderstanding what mode the plane's autopilot was in

00:03:25.120 --> 00:03:30.720
leading the plane to touch down short of the runway so it may not be surprising

00:03:28.959 --> 00:03:34.480
that on something as complicated as an airplane computers are capable of

00:03:32.640 --> 00:03:38.720
becoming confused just like they're fallible human pilots but the hope is

00:03:36.720 --> 00:03:42.480
that as we learn from mishaps and pilots become more accustomed to using

00:03:40.080 --> 00:03:47.200
automation flying can continue to get progressively safer speaking of safety
