airports and planes

don’t look back, you’re not going that way


No One Can Explain Why Planes Stay In The Air

On a strictly mathematical level, engineers know how to design planes that will stay aloft. But equations don’t explain why aerodynamic lift occurs.

There are two competing theories that illuminate the forces and factors of lift. Both are incomplete explanations.

iBorderCtrl is an AI based lie detector project funded by the European Union’s Horizon 2020. The tool will be used on people crossing borders of some European countries. It officially enables faster border control. It will be tested in Hungary, Greece and Letonia until August 2019 and should then be officially deployed.

The project will analyze facial micro-expressions to detect lies. We really have worries about such a project. For those who don’t have any knowledge on AI and CS, the idea of using a computer to detect lies can sound really good. Computers are believed to be totally objective.

But the AI community knows it is far from being true: biases are nearly omnipresent. We have no idea how the dataset used by iBorderCtrl has been built.

More globally, we have to remind that AI has no understanding of humans (to be honest, it has no understanding at all). It just starts being able to recognize the words we pronounce, but it doesn’t understand their meaning.

Lies rely on complex psychological mechanisms. Detecting them would require a lot more than a simple literal understanding. Trying to detect them using some key facial expressions looks utopian, especially as facial expressions can vary from a culture to another one. As an example, nodding the head usually means “yes” in western world, but it means “no” in countries such as Greece, Bulgaria and Turkey.

The ‘iBorderCtrl’ AI system uses a variety of ‘at home’ pre-registration systems and real time ‘at the airport’ automatic deception detection systems. Some of the critical methods used in automated deception detection are that of micro-expressions. In this opinion article, we argue that considering the state of the psychological sciences current understanding of micro-expressions and their associations with deception, such in vivo testing is naïve and misinformed. We consider the lack of empirical research that supports the use of micro-expressions in the detection of deception and question the current understanding of the validity of specific cues to deception. With such unclear definitive and reliable cues to deception, we question the validity of using artificial intelligence that includes cues to deception, which have no current empirical support.

[T]hough air travel is safer than it has ever been, the intervening time has not provided an enormous upgrade of our ability to track aircraft far from land-based radar. […]

[O]ver international waters, air traffic controllers have no real-time knowledge of where planes are—they rely on flight plans, radio contact with pilots, and a system called ACARS that provides what is effectively text-message communication between planes and ground stations. […]

In 2010, the FAA mandated that all US aircraft would need to use a system called ADS-B, which means “Automatic Dependent Surveillance—Broadcast.” Essentially, by 2020, aircraft are required to broadcast their location, derived from GPS, each second. […]

However, ground receivers need to be within about 172 miles (277 km) of the aircraft to collect ADS-B signals. Out over the ocean, there’s still a knowledge gap between the planes and the air traffic controllers they can’t reach. […]

The solution: more satellites.

Specifically, Aireon has installed payloads on 75 Iridium satellites that have been launched over the past two years, with the final installment reaching orbit in a SpaceX rocket on Jan. 11. These payloads are designed to detect ADS-B signals wherever they are broadcast, whether over the open ocean or a mountain range, finally providing continuous tracking of aircraft anywhere on Earth. The satellites are already processing more than 13 billion ADS-B messages each month. […]

For airlines themselves, the benefits will include using that real-time traffic management to fly faster, in part because they will be able to fly more closely to other planes, which will cut fuel costs (and emissions).

The travel booking systems used by millions of people every day are woefully insecure and lack modern authentication methods. This allows attackers to easily modify other people’s reservations, cancel their flights and even use the refunds to book tickets for themselves.

Commercial drone flights are set to become a widespread reality in the United States, starting next year, under a 2012 law passed by Congress. […]

Military drones have slammed into homes, farms, runways, highways, waterways and, in one case, an Air Force C-130 Hercules transport plane in midair. […]

Several military drones have simply disappeared while at cruising altitudes, never to be seen again. […]

The documents describe a multitude of costly mistakes by remote-control pilots. A $3.8 million Predator carrying a Hellfire missile cratered near Kandahar in January 2010 because the pilot did not realize she had been flying the aircraft upside-down.

These new robot-painting machines can wash, apply solvent to remove dirt, rinse and then spray two different paint types. […]

Manually, it takes a team of painters 4.5 hours to do the first coat. The robots do it in 24 minutes with perfect quality. Boeing began using the machine in February. By midsummer, all 777 wings will be painted this way. […]

Half the 777 wing-painting team has been redeployed to other roles, such as programming the machines, painting the airline liveries on the fuselage or working on the sophisticated paint job needed for the 787-9 tails, which have a special smooth aerodynamic finish, Clark said.

On April 7, 1994, Federal Express Flight 705, a McDonnell Douglas DC-10-30 cargo jet ferrying electronics across the United States from Memphis, Tennessee to San Jose, California, experienced an attempted hijacking for the purpose of a suicide attack.

Auburn Calloway, a FedEx employee facing possible dismissal for lying about his previous flying experience, boarded the scheduled flight as a deadheading passenger with a guitar case carrying several hammers and a speargun. He intended to disable the aircraft’s cockpit voice recorder before take-off and, once airborne, kill the crew using the blunt force of the hammers so their injuries would appear consistent with an accident rather than a hijacking. The speargun would be a last resort. He would then crash the aircraft while just appearing to be an employee killed in an accident. This would make his family eligible for a $2.5 million life insurance policy paid by Federal Express.

Hijacking airplanes with an Android phone

By taking advantage of two new technologies for the discovery, information gathering and exploitation phases of the attack, and by creating an exploit framework (SIMON) and an Android app (PlaneSploit) that delivers attack messages to the airplanes’ Flight Management Systems (computer unit + control display unit), he demonstrated the terrifying ability to take complete control of aircrafts by making virtual planes “dance to his tune.”

As a gateway to the city, Los Angeles International Airport could hardly be more dispiriting. A jumble of mismatched, outdated terminals, LAX gives visitors a resounding first impression of civic dysfunction.

The city, which owns the airport, has tried several times to remake LAX. The latest attempt is a master plan by Fentress Architects, which is also designing the nearly $2-billion Tom Bradley International Terminal.

But the truth is that the airport’s biggest liability is not simply architectural. Somehow Los Angeles built a major rail route, the Green Line, past LAX 20 years ago without adding a stop at the airport.

And guess what? We are about to build another light-rail route — this time the $1.7-billion Crenshaw Line — near the airport and make precisely the same mistake again.

These days, the TSA’s major role appears to be to make plane trips more unpleasant. And by doing so, it’s encouraging people to take the considerably more dangerous option of traveling by road. […]

A longer list of TSA’s confiscations would include a G.I. Joe action doll’s 4-inch plastic rifle (“it’s a replica”) and a light saber. […]

Researchers at Cornell University suggest that people switching from air to road transportation in the aftermath of the 9/11 attacks led to an increase of 242 driving fatalities per month—which means that a lot more people died on the roads as an indirect result of 9/11 than died from being on the planes that terrible day. They also suggest that enhanced domestic baggage screening alone reduced passenger volume by about 5 percent in the five years after 9/11, and the substitution of driving for flying by those seeking to avoid security hassles over that period resulted in more than 100 road fatalities.

One of the nightmare scenarios for modern society is the possibility of a global flu pandemic like the 1918 Spanish influenza which infected about a quarter of the global population and killed as many as 130 million of them.

An important question for policy makers is how best to limit the spread of such a disease if a new outbreak were to occur. (The Spanish flu was caused by the H1N1 flu virus that was also responsible for the 2009 swine flu outbreak.)

One obvious idea is to close international airports to prevent, or at least dramatically reduce, the movement of potentially infected individuals between countries. But is this the best approach?

Today, Jose Marcelino and Marcus Kaiser at Newcastle University in the UK, provide an answer. They say a better approach is to cut specific flights between airports because it can achieve the same reduction in the spread of the disease with far less drastic action.

When you fly trans-Atlantic, why does the plane not go straight? One would think the shortest route would be a straight line from say NYC to London… but the plane makes a curve…

What is a straight line on the globe may appear as a curved line on a flat map. Use a globe and hold a piece of string tight against it with one end at each of the two cities you are flying between. You might find that this gives you a very different path than if you drew a straight line on a map. (…)

For example, a direct line from Toronto to Tokyo goes through Alaska and Siberia. On a flat map with the north pole at the top, this would look like an arch. (…)

Notice that the red line is shorter than the blue line. The sphere has a smaller circumference as you get closer to either of the polls than it does at the equator (closer to the blue line)
 
If you were to fly directly to your destination on a transatlantic flight (let’s say along the blue line), you would have to fly a much further distance than if you bowed up north over Greenland (and flew closer to the red line) for a bit.

North Atlantic Tracks (NAT) are trans-Atlantic routes that stretch from the northeast of North America to western Europe across the Atlantic Ocean. They ensure aircraft are separated over the ocean, where there is little radar coverage.

These heavily-traveled routes are used by aircraft traveling between North America and Europe, flying between the altitudes of 28,500 and 42,000 feet, inclusive. Entrance and movement along these tracks is controlled by special Oceanic Center air traffic controllers to maintain separation between airplanes.

The primary purpose of these routes is to provide a Minimum Time Route. They are aligned in such a way as to minimize any head winds and maximize tail winds impact on the aircraft. This results in much more efficiency by reducing fuel burn and flight time.

To make such efficiencies possible, the routes are created daily to take account of the shifting of the winds aloft. (…)

Concorde did not travel on the North Atlantic Tracks as it flew to the United States from the United Kingdom and France from a much higher altitude, between 45,000ft and 60,000ft. The weather variations at these altitudes were so minor that Concorde followed the same route each day, traveling to and from Europe to North America on fixed tracks.
