Hey Dan, we're getting ready to land. 00:00:00
You know, airplanes arrive from several different directions, and the Air Traffic Control Center 00:00:07
has to merge all those planes into a single file line, making sure there's a safe distance 00:00:12
between each plane. 00:00:17
Right, and since air traffic can sometimes arrive like rush hour traffic on a highway, 00:00:19
pilots may have to adjust their flight plans, change their speed or altitude, or go into 00:00:24
a holding pattern. 00:00:28
Some of these adjustments may cause delays. 00:00:30
However, safety comes first. 00:00:32
That's right. 00:00:34
When we are about 6 to 18 kilometers from the airport, the Air Traffic Control Center 00:00:35
hands us off to the San Francisco Airport Control Tower. 00:00:40
Tower controllers there relay current weather and air traffic information to our pilot. 00:00:44
Wow, what a ride. 00:00:48
Hey, there's the control tower. 00:00:52
I wonder what they're doing in there. 00:00:54
Let me tell you, now that we've landed, controllers in the tower tell our pilot which taxiways 00:00:56
to use and where we can park. 00:01:01
You know, we're not completely safe until we've parked at the gate and our pilot has 00:01:04
turned off the fasten seatbelt sign. 00:01:07
San Francisco, here we come. 00:01:09
While NASA's Aviation Safety Program is helping pilots maintain high levels of safety in our 00:01:26
skies, NASA is also working to help airports operate more safely and efficiently. 00:01:41
As airplane traffic increases in our skies, the possibility for more accidents or incidents 00:01:46
also increases on the ground. 00:01:51
Pilots have flight simulators to simulate conditions in the air, but what about people 00:01:53
in control towers who monitor and direct takeoffs and landings? 00:01:57
Yeah, I mean, could all the people that guide airplanes to the ground, like pilots, air 00:02:01
traffic controllers, and airport operators, work together and try out new ways to safely 00:02:06
move planes around an airport? 00:02:11
NASA believed they could, so a unique facility was built right here in California to help 00:02:13
solve present and future problems of our nation's airports. 00:02:18
It's called NASA Future Flight Central. 00:02:21
And to learn more, we came here to NASA Ames Research Center in Moffett Field, California. 00:02:23
Why was NASA Future Flight Central built? 00:02:33
How does NASA use technology to simulate airports? 00:02:35
Analyzing the graph, what factors do you think influence the air traffic controller's response? 00:02:39
NASA Future Flight Central is a two-story facility with a 360-degree view. 00:02:45
It's capable of doing a full-scale, real-time simulation of an airport. 00:02:51
It's where air traffic controllers, pilots, and airport personnel can interact with each 00:02:55
other and test out new technologies. 00:03:00
As you can see, this is designed to look very much like a real air traffic control tower. 00:03:02
The downstairs rooms support the simulation. 00:03:07
We bring in real air traffic controllers. 00:03:09
They wear headsets and communicate with the pilots, giving them permission to taxi, take off, and land. 00:03:12
At the same time, they also scan the runways and taxiways to make sure that all the airplanes 00:03:18
are maintaining a safe distance from each other, just as you do while driving an automobile. 00:03:23
How do you make this tower and these planes look so real? 00:03:28
With a supercomputer. 00:03:32
We create a virtual airport environment, which means it is made to look very realistic when 00:03:34
compared to an actual airport. 00:03:39
We do this by using satellite imagery, aerial surveys, and digital photography. 00:03:41
Simulation software allows us to move 200 vehicles, like airplanes or ground trucks, 00:03:47
all at the same time and at realistic speeds. 00:03:53
We can simulate a variety of weather conditions, like dense fog, rain, or snow. 00:03:56
We can also place numerous planes on the runway that need to move all at once, making the 00:04:02
test as realistic as possible. 00:04:07
For example, an airplane can be placed where it shouldn't be, and the air traffic controllers 00:04:09
have to try to safely get the plane out of the way to avoid a collision. 00:04:14
Nancy, that is so cool. 00:04:18
Sounds like NASA Future Flight Central simulates many of the conditions that happen at our nation's airports. 00:04:19
That's right. 00:04:24
Not only at our facility can we duplicate a real airport and operate it as it runs today, 00:04:25
but we can also make changes and see if we can make things safer. 00:04:30
For example, we conducted a study of San Francisco International Airport. 00:04:34
Currently, the airport is conducting an environmental review to assess the possibility of building new runways. 00:04:38
Because of space limitations, these new runways would be built out into San Francisco Bay. 00:04:44
This could possibly cause the airport to relocate its control tower. 00:04:50
Using our facility, we simulated the San Francisco airport and built the new runways. 00:04:54
Then, for each proposed location of the tower, we moved some planes down the runway and watched the view. 00:05:00
Without Future Flight Central, the airport might move its tower to a location when blocked views 00:05:05
and wouldn't be able to operate the airport safely. 00:05:10
Has NASA used this facility to simulate any other airports? 00:05:12
We sure have. 00:05:16
Recently, NASA did a study of the Los Angeles International Airport, or in airport terms, LAX. 00:05:17
Our goal was to simulate a realistic operating environment that was as close as possible 00:05:23
to what the LAX air traffic controllers experience every day in the tower. 00:05:29
This study was different from the one on the San Francisco airport 00:05:33
because before we could simulate any changes to LAX, 00:05:37
we had to first make sure that we could realistically simulate one of the busiest airports in the world. 00:05:40
So, how did you determine if the simulation was as realistic as the real LAX? 00:05:46
Just like you do in math class, Dan. 00:05:51
First, we collected data from the air traffic controllers using questionnaires. 00:05:53
Using the data, we created an interpreted graph to determine if we accomplished our goal. 00:05:58
There were many factors involved in determining whether our simulation was realistic. 00:06:03
Let me show you one of the graphs we created. 00:06:08
The title of the graph is Realism Ratings for LAX Air Traffic Controllers. 00:06:10
This graph tells us how the real LAX controllers rated our simulation. 00:06:15
Okay, let's see. 00:06:20
Along the bottom are ratings from 1 to 5, with 1 being not at all realistic 00:06:21
and 5 being identical to LAX. 00:06:27
Nancy, what is a ground air traffic controller and a local air traffic controller? 00:06:30
A ground controller is responsible for airplanes on the ground, 00:06:34
leaving the gate and taxiing to the runway, for example. 00:06:38
A local controller issues takeoffs and landings, 00:06:41
maintains a safe distance between arriving and departing aircraft, 00:06:44
and is responsible for controlling flights up to 16 kilometers from the tower. 00:06:48
Let's put the data on the graph. 00:06:53
As you can see from the data we collected, 00:06:55
both the ground and local controllers believe that our simulation of airplanes on the ground 00:06:58
and in the sky met our goal of being realistic compared to LAX. 00:07:03
In fact, the data shows that we exceeded our goal and we were very realistic compared to LAX. 00:07:08
Just as John collects data to help train pilots for safety, 00:07:14
Future Flight Central will realistically simulate our nation's airports 00:07:18
so they can continue to run smoothly and safely. 00:07:22
Nancy, that's amazing that NASA realistically simulated one of the world's busiest airports. 00:07:25
So what's next? 00:07:31
The next step will be to determine what will and what will not work 00:07:32
when proposed changes are made to the LAX operating environment. 00:07:36
Because Future Flight Central is a safe place to try out new airport procedures, 00:07:40
both time and money will be saved as LAX continues to put safety first. 00:07:44
Thanks, Nancy. 00:07:50
Okay, so far on today's show, Dan and I have flown from Virginia all the way to California. 00:07:51
And during this flight, we learned how NASA's wind tunnel tests are helping train pilots to be even safer. 00:07:57
We also learned how airplanes and passengers get from gate to gate 00:08:03
and how NASA uses simulations to make airports safer. 00:08:06
So, do you have what it takes to be an air traffic controller? 00:08:09
See if you can safely and efficiently land airplanes at Norbert International Airport. 00:08:13
