How Plane Accidents, like the DC Crash, Are Investigated

Plan accidents, like a DC accident, are investigated

In Washington, a video camera at the DC Kennedy Center, captures a chiarrare image of the nightscape of the nation’s capital. An upper approach to a bank plane. It moves towards the camera and then pass without feedback. Turning off the distance, the bright blip in the sky moves slowly. The point of light is more accurate in a faster rhythm behind. In a few seconds, the larger the smaller aircraft and a great flash that turns the night sky on the potomac river at hundreds of feet above the river.

With your finger, Black Uh-60 Black Wicopter against 5342 American Flight Wekopter. Understanding, the events were amazed by experts and public flying. Traveling to the US Air Space has been a very safe experience for many years. He had a commercial aircraft that had an accident and important murder 2009.

Ronald Reagan Washington National Airport remains challenging pilots, heavy traffic and limited airport, near areas like white and pentagon. Potomac is the site of an important previous accident: in 1982 Air Florida flight fell on a bridge As he entered a storm and then entered the frozen river, 79 people were killing 74 in the boat and four motorists on the bridge. In recent years, Misses in the national rian It happened on the ground, cross-plane crosses in many events recorded by the Federal Aircraft Administration.

How do air security officials continue to investigate such an important accident? American scientific Put this question to Kryy Kiernan, the Association of the Boeing Center at Aironautical University of Aviation and Aerospace Security.

(It follows the edited transcript of the conversation.Diagnies

Accidents on the commercial plane are rare, and many people ask how we know what happened to the event of yesterday.

There are very clearly specified processes for this purpose. NTSB (National Transport Safety Commission) has a “Go” Group, and once the rescue and recovery operations are increasing, the recovery of sinking of the sinking of false care environments can cause attention environments or movements. So it’s a very important thing to gather perishable evidence. Of course, after securing the scene and it is possible to operate safely, there are many risks in an accident scenario, so it is an important factor in protection and research of people who make rescuing and recovery.

What is ISO coming after that?

Of course, black boxes, voice and data recorders are very important to recover. Would be in the region’s jets. I don’t know what kind of recording devices uh-60 (helicopter). But in general, the black boxes are a big axis. Then there are several groups called operations, maintenance, air traffic control, weather and all of these groups, among other things, experts in human factors investigate their particular field.

So, for example, in the air traffic control, you would secure air traffic control radar and the tape of all communications. Also, for the Army and PSA Airlines (for American American Airlines for the accident, there will be a collection of evidence related to people involved in the operation of the aircraft, including their training records. If things don’t have to be, the effort in a certain area is proportional to the role that a particular fact is performed in the study. So more and more resources will be extended to the areas that progress progress. All it takes time. We have a quick new cycle, and the public should receive information as soon as possible, but it is best to wait for good information than providing speculation and opinion in any planes.

Can you describe what has learned to seek past research?

I would say that we have existing security layers. And, for example, there are planes that are in heaven and what the heights are. Then we have technologies. We have systems to avoid collisions. We call ADS-B, automatic dependency surveillance emission. That is another tool used to raise awareness where other aircraft are in the air space. We have very trained air traffic controllers, and in many cases in the past, they have been instrumental to avoid collision with Midra. Then we had experienced pilots trained in the regional jet and army helicopter and experienced aircraft.

But that’s not always enough, right?

So we usually have all these layers. However, we need to admit that we require many of our systems. We have this area in Washington, (DC), high density, high volume and high rhythm of operation. While we are driving on a different margin of security, when you are driving on a snowy road, you can maintain secure operations: your risk profile and your security margin is only different on a beautiful Sunday evening. So our margins are thinner sites, and these are the areas we need to be really attentive.

If people were to see all the activities that keep air space safe, I think they would be reassured. But the last thing I would say is that we should be comfortable in the place where we are now. We should always be, as a plane security professionals, we need to be uncomfortable. For the public trip, I think it can take comfort every day for these activities that go every day. But it is also an accident, when there is 40,000 operations in the US home air space every day.

Air accidents with mass deaths are rare. Somehow don’t investigate so harder?

I don’t know if it is a greater challenge for research (such accidents). It is certainly predicted (them) to understand the many models in the industry because there is different things that enter an accident. There is no smoking gun; There is no single causal factor. Even if you find a thing, there is a reason for that thing, and that’s why it’s more complicated. If you identify the one thing, you don’t fix anything. You have to go deeper and look at why. These accidents are very rare. So the likelihood of what is repeated, especially after taking measurements, is very low. But we can’t stop there. We want to use each thing to study all the factors, we are able to identify the risks and risks we need to advance and relieve us.
