Have you ever been delayed at the airport? Chances are that you have. 00:00:00
Most of us assume that flight delays are just an unfortunate part of traveling. 00:00:04
Well, researchers at NASA are working on a program called Aviation Systems Capacity 00:00:08
that just may make flight delays a thing of the past. 00:00:13
Our own Jennifer Cortes takes us to NASA Ames to find out more. 00:00:16
Have you ever been in this situation? 00:00:26
Long lines at the airport? Your flight's been delayed again. 00:00:28
Sitting on the runway waiting to take off or circling the airport waiting to land. 00:00:32
Unfortunately, it seems as if delays and cancellations are becoming a routine part of travel. 00:00:37
Over the next 20 years, the demand for air travel is expected to double, 00:00:42
which could make these delay problems much more frequent. 00:00:46
In fact, by the year 2012, there will be over 1 billion passengers traveling on domestic flights annually. 00:00:50
But is there anything that can be done about these delays? 00:00:57
Well, researchers at NASA are working on something called Aviation Systems Capacity, 00:01:00
which may someday make flight delays a thing of the past. 00:01:06
There are many factors that affect delays at major airports throughout the country. 00:01:10
The major one is that there is just an exponential growth in the amount of traffic in the air traffic system. 00:01:16
And unfortunately, we are just using the old air traffic control system that has been around for years. 00:01:23
To better understand why some airport delays happen, think about your own rush hour traffic. 00:01:30
As long as everyone is going the same speed, traffic moves smoothly. 00:01:36
But if weather is bad or a few cars or trucks slow down, then huge backups can happen. 00:01:40
That same basic thing is happening in the airport environment. 00:01:46
Traffic may be running smoothly, but if one plane is delayed because of weather, backups start to occur. 00:01:50
Unfortunately, if planes are late leaving one airport, 00:01:56
then those same planes arrive late at other airports, causing further delays. 00:01:59
NASA's goal is to safely increase the capacity and productivity of national airspace 00:02:04
by developing revolutionary operation systems and vehicles. 00:02:10
NASA has been working on three projects. 00:02:14
And these three projects are aimed at trying to develop the technologies 00:02:18
that will increase the capacity on the national level. 00:02:22
The first two projects are the Advanced Air Transportation Technologies Project 00:02:25
and the Terminal Area Productivity Project. 00:02:30
Those two combined are looking at technologies that will help reduce the workload 00:02:33
of both pilots and controllers at major airports. 00:02:38
In addition to that, NASA is developing an aircraft that will be able to fly 00:02:43
in and out of major airports without needing the runways. 00:02:48
Frank, I know that you want to get aircraft in and out of airports faster. 00:02:52
How are you going to do that? 00:02:55
Well, Jen, since 70% of all delays in and out of major airports are caused by weather, 00:02:57
NASA is working on technology that will allow traffic to safely come in and out of these major airports, 00:03:02
even under bad weather. 00:03:09
And so in order to do that, NASA is working on a technology called Airborne Information 00:03:11
for Lateral Spacing, which will provide the pilot the ability to see other traffic 00:03:17
even during the bad weather times so that they can safely come in and out of these airports. 00:03:23
So based on doing that, we would be able to increase capacity at major airports. 00:03:29
And the third element in the capacity program is the Short-Haul Civil Tilt Rotor Project. 00:03:34
The Civil Tilt Rotor aircraft offers a unique opportunity to alleviate runway congestion at the busiest airports. 00:03:40
With the advantage of vertical takeoffs and vertical landing, 00:03:46
tilt rotors don't rely on conventional runways and can bypass ground and air congestion, 00:03:49
which reduces door-to-door trip times for passengers. 00:03:55
With trips of less than 500 miles, tilt rotors will reduce the amount of fixed-wing flights, 00:03:58
which would free up runway space for larger aircraft. 00:04:03
The benefits of the tilt rotor are that you can take off and land vertically, 00:04:07
and then you can fly like an airplane. 00:04:12
So it can fly twice as far and fast as a helicopter, 00:04:14
and at its destination, the reverse occurs and it lands like a helicopter. 00:04:19
And the big advantage is you don't need runways. 00:04:24
And also, you don't even need airports. 00:04:27
You can fly to small landing areas that we call vertiports, 00:04:30
and these could be located much closer to where you're going or where you're coming from. 00:04:35
And therefore, you avoid all of the congestion on the ground and at the airport and in the air. 00:04:40
That's why I believe the tilt rotor will revolutionize air travel. 00:04:47
