European aerospace1 company Airbus has fitted a special truck with airplane controls in an effort to test self-taxiing abilities.

Airbus officials recently introduced the truck in Paris at Europe's largest technology event, VivaTech. The electric vehicle can drive like a truck, or it can activate2 the aircraft system controls.

A demonstration3 showed how the truck works. It uses numerous cameras and sensors4 to help follow airport direction signals and avoid obstacles as computers guide the vehicle along its path.

In a statement, Airbus described the effort as a three-year research project called Optimate. The goal is to deploy5 and test the best technologies to help aircraft better recognize their surroundings and current operating conditions.

In addition, the company said detailed6 data from the experiments will be examined to help develop pilot assistance systems for airport taxiing.

The technology demonstration came after several incidents of airplanes crashing on the ground at airports. One of those happened in January, when a Japanese Airlines Airbus350 was landing and hit a coast guard plane already on the runway.

An investigation7 was launched last month after a British Airways8 jet struck a stationary9 Virgin10 Atlantic plane at London's Heathrow Airport. That crash caused only minor11 damage to both aircraft.

And in February, U.S. investigators12 said they were looking into a crash involving two JetBlue planes at Logan International Airport in Boston.

Airbus officials have said they hope the specially13 designed truck can show how self-taxiing, or automation, technology can help safely guide costly14 jets through increasingly crowded airports. The vehicle uses multiple technologies related to automation, navigation and artificial intelligence (AI).

Matthieu Gallas is the head of automation research at UpNext, a special technology research laboratory for Airbus. He told Reuters news agency, "These use cases are much more critical and complicated compared to those of the car industry."

Slow-speed airport crash incidents rarely result in serious injuries or deaths. But they represent a costly and growing problem for airlines, airports, insurers and passengers. Such incidents can cause major passenger delays. They also can lead to costly plane repairs.

The chief executive of UpNext is Michael Augello. He said in a statement that a big aim of the Optimate project is to demonstrate a new system to support "safer and more efficient air travel."

The UpNext team says the refitted truck is to be tested live at airports in preparation for testing A350-1000 aircraft in the future.

Company officials say if the airport tests are successful, the project could also result in airplane design changes. But getting such systems approved can be a long and difficult process.

Gallas said Airbus jets already use some automation technologies to limit pilot error. But those systems are not considered fully15 autonomous16. In other words, they can only predict and behave in certain situations.

The testing truck is equipped with light-based LiDAR technology. LiDAR uses a series of sensors and light lasers that can measure distances and produce three-dimensional (3D) maps of the surrounding environment.

Airbus said the research vehicle is expected to explore progressively higher levels of automation as the experiments continue. The company noted17 it has no immediate18 plans to introduce autonomous jetliners to the skies.

Karim Mokaddem is a former automobile19 executive. He now leads research and technology for Airbus. He told Reuters he thinks LiDAR will be the most effective technology for the testing vehicle.

The possible use of LiDAR to improve aircraft safety recently received attention after severe turbulence20 hit a Singapore Airlines jet. That incident left one passenger dead and several others injured.

Researchers have looked at LiDAR technology as a possible way to identify and track possibly dangerous air currents that may not be picked up by radar21 equipment.

Reuters reported that Boeing began testing such a system in 2018. Technology experts are looking to possibly expand LiDAR as a tool to help predict turbulence.
