Ready for pilots to fly your airliner by voice
commands?
Engineers developing cockpit system to control
airliners with voice commands
Cedar Rapids, Iowa (CNN) -- My hand
grips the airplane control stick as I brace myself in the cockpit. Spread out in
front of me is a breathtaking landscape stretching hundreds of miles.
I've
never flown a plane in my life. But now, I'm about to steer -- using my
voice.
"Turn left, heading 0-6-0," I command, feeling a little like an
airline pilot.
A female mechanical voice repeats back: "Turn left,
heading 0-6-0." To confirm, I press a tiny red button on the cockpit control
stick. Suddenly the horizon in front of me banks sharply to the right.
Well,
no, I'm not actually flying a real plane. I'm operating a machine that simulates
how airline pilots will fly in the future.
The friendly engineers here at
Rockwell Collins' Advanced Technology Center in Iowa are letting me play with
their new pilot voice recognition technology.
Its Advanced Technology Center helps Rockwell
Collins develop sophisticated cockpit technology for pilots of the
future.
Hey, do these folks know they've let a kid run loose in an
avgeek candy store?
This is sophisticated stuff. In fact, the Pentagon uses
speech recognition systems aboard its top-shelf fighter jet, the F-35. Maybe
someday your airliner pilot will do the same.
Engineer Geoff Shapiro,
who's showing me how the simulator works, hopes this technology can save airline
pilots crucial seconds after they receive commands from controllers.
"A
complicated command from air traffic control can take pilots up to 30 seconds to
actually turn all the knobs, hit all the buttons and make that change actually
occur," Shapiro says.
The speech recognition system cuts that time to eight
seconds, he says, giving pilots 22 more seconds to "spend keeping their eyes out
looking to see where the traffic is, looking to see where the weather is,
keeping the airplane safe."
Before this voice recognition system
executes a command, a pilot double-checks its work. That means no voice command
is ever executed until the pilot confirms the command is correct. The pilot does
that by pressing the control stick's little red button.
Would passengers
be comfortable with airline pilots steering via voice commands? Would they feel
safe?
"I'm gonna have to think about that idea," a fellow passenger tells me
later at Atlanta's Hartsfield-Jackson airport. "I can't tell you how many times
my phone misspells my voice dictation. I think I'd feel more comfortable if the
pilot just flew the regular way."
Boeing 777 airliner pilot Keith
Wolzinger doesn't think voice recognition steering is all that necessary. "I'm a
bit skeptical," he tells me. With two pilots in the cockpit, responding to
controller commands doesn't take a lot of time, Wolzinger says. "I'd communicate
with air traffic control and I'd just ask my first officer to make the
turn."
In the simulator, Shapiro lets me test the technology while I
"fly" over a simulated Mount Rainier in Washington state.
I wonder, does
it respond to whispers? I whisper a command into the headset. The voice repeats
back my command perfectly. I push the little red button. The plane
turns.
Interactive airport maps displayed in the cockpit
would help commercial airline pilots avoid getting on the wrong runway or
colliding with other aircraft.
What about screw-ups? What if a pilot
accidentally speaks into the headset and says something random?
I say, "Let's
go out to dinner in Los Angeles!" Does the voice system freak out? Nope.
"Say
again," she says. It didn't understand, because the system only recognizes
legitimate, preprogrammed commands.
What about accents? Does it
understand Southern American twang? I give it my best -- followed by English
with a French-ish twist. Yep, it understands.
Would voice recognition
ever replace the traditional yoke and stick that pilots use to steer? "I think
you're always going to need some type of manual control of the aircraft," says
Shapiro.
Of course Rockwell Collins doesn't call this the Advanced Technology
Center for nothing. The stuff in here won't see the commercial market for at
least a decade -- if ever. So steering by voice has a long way to go before it
even gets close to entering the flight deck of your airliner.
In these
rooms, Rockwell Collins has been designing cockpit systems for business jet
makers and airliner manufacturers like Boeing and Airbus for decades. It also
creates technology for military aircraft all around the world.
Suddenly,
as we walk down a hallway, I see a pair of glossy black fighter pilot helmets
being rolled on a cart. "What are these?" I ask.
A helmet developed by Rockwell Collins for Lockheed
Martin F-35 fighter jets allows pilots to "see" through the cockpit like "X-ray
vision."
Turns out they're the next generation of pilot helmets with
built-in visual displays: the StrikeEye.
Imagine a fighter pilot helmet that
projects a data-rich visual display in front of the pilot's eyes. That kind of
system could help pilots have a better visual sense of everything around them:
buildings, landscape and other aircraft. This helmet creates a virtual
360-degree 3-D view that allows pilots to "see" THROUGH the aircraft itself and
scan the horizon and the ground below.
StrikeEye is nearly identical to
helmets Rockwell Collins provides to Lockheed Martin for U.S. military pilots of
the F-35.
In fact, a lot of new cockpit technology coming in the next 25
years includes jaw-dropping video-game-like graphics and 3-D displays.
Synthetic Vision allows pilots to "see" through
clouds by displaying a virtual landscape created with GPS and a data base of
super-accurate maps.
Here's another example: We all know that
blinding rain, snow or clouds result in countless flight delays or cancellations
every year. But what if pilots could fly through blinding weather with the help
of a real-time video display of the landscape that looks like the real
thing?
The technology exists.
Shapiro shows me what the industry calls
"synthetic vision" and "enhanced vision" technology. This sort of thing is
already available aboard some business jets. Synthetic vision uses GPS and
super-detailed maps to "see" through clouds by creating a virtual reality view
of the landscape ahead, displayed on a small screen in front of the pilot.
Enhanced vision uses infrared sensors that work like "X-ray vision" through bad
weather.
If airlines embraced these kinds of systems, it could
significantly reduce delays and cancellations, manufacturers say. That might
lead to lower fares and happier travelers who get where they want to go, when
they need to get there.
Another emerging cockpit technology: touch-screen
steering.
We already control navigation systems in our cars with touch
screens. Eventually, airline pilots may be able to steer with them. With the
touch of a console display screen, pilots could execute precise turns and
changes in speed.
A Rockwell Collins engineer demonstrates a system
that allows pilots to change direction, speed and altitude with a
touchscreen.
Touch-screen steering, voice recognition, synthetic
vision, Shapiro says, all point toward a future when airliners will be flown by
one pilot instead of two.
Shapiro says the industry is looking at the
possibility of reducing typical airline flight crews to one pilot in the cockpit
and one support person on the ground. The support person would likely be ready
at any time to help the pilot if anything goes wrong. But that's many years down
the road, if ever.
Is the industry moving toward a day when airliners will
fly themselves? In other words, will human airline pilots be obsolete
someday?
"I certainly think that we¹re moving toward pilotless
airliners," Shapiro says. The technology already exists, he points out -- look
at the rapid development of large, unmanned drones, for example. But the public
would be slow to accept the technology and to have faith in it, Shapiro
says.
Overall, "it¹s going to take, I think, quite a long time before all
those pieces come together."
