The common belief with airplanes is that they fly themselves after take-off thanks to autopilot, and pilots can sit back and relax for most of the flight. But Airbus just took that idea to the next level after proving a passenger jet can perform complex maneuvers without any pilot input.
The European manufacturer just completed flight testing for its Autonomous Taxi, Take-off, and Landing project in June after its flagship aircraft successfully navigated each phase of flight on its own as pilots simply watched.
Over 500 flights were conducted with the new Airbus A350-1000 XWB that successfully utilized “image recognition technology” to essentially give the plane a pair of eyes. The technology, integrated with the A350’s exterior cameras, allowed it to perform the phases of flight entirely on its own, Airbus announced.
The first milestone of the flight testing campaign occurred in December when Airbus was able to successfully demonstrate autonomous take-offs from Toulouse-Blagnac Airport in France. All pilots had to do in the first test was line up the plane with the runway and then sit back and watch as the plane barreled down the runway, lifting off on its own.
With Airbus proving that its jet can also land and taxi on its own, the door is now open to fully autonomous flights.
Here’s how Airbus was able to do it.
Installing a fresh pair of eyes for an aircraft
Airbus began the autonomous flight testing program – known as the Autonomous Taxi, Take-off, and Landing project or ATTOL – in 2018, according to the manufacturer. One of its newest jets, the Airbus A350-1000 XWB, was chosen to be the testbed for the project thanks to the advanced technological features of the aircraft.
The program would rely heavily on the A350’s onboard cameras used by pilots to help guide the plane while on the ground, providing viewpoints from the tail and landing gear. Even passengers can access them for a unique view of take-off and landing, a reprieve from the standard onboard programming of TV shows and movies.
Airbus integrated the camera system with the new tech to give the plane eyes, essentially, and allow it to see the runway and taxiways.
The first success autonomous test occurred in December with an automatic take-off performed using the new technology. Pilots just had to line the plane up and then the jet took over, navigating independently as it accelerated down the runway and lifting off at the appropriate time.
Any number of factors – including wind – can knock a plane off-course during take-off and the pilot has to correct the plane’s heading when it does. But that wasn’t the case here as the airplane did all the work.
Learning to land and taxi on its own
Once take-offs were nailed down, it will time to teach the jet how to land on its own. Nearly all passenger jets can land with a high degree of automation thanks to GPS and radio signals providing information but these autonomous trials would have the airplane do all the work, independent of existing infrastructure.
A total of 30 landings were achieved autonomously across six flights, with Airbus declaring victory on the program after performing over 500 flights to collect data and demonstrate the viability of the technology.
Airbus has also successfully completed autonomous taxi tests, a difficult task as taxiways are less easily identified than runways. Taxiing has always been the responsibility of the pilots due to the complexity of the task, even on the ground.
The new technology could revolutionize how airlines operate their planes, especially as the A350 is growing in popularity and is in the fleets of countless airlines such as Virgin Atlantic Airways, Delta Air Lines, Fiji Airways, Air France, Cathay Pacific, South African Airways, Singapore Airlines, and Qatar Airways, among others.
The manufacturer has been moving full-steam ahead with automated tech not only in the passenger realm but also in its military division. An Airbus A310 MRTT completed an automated air-to-air refuel in April over the Atlantic, the first aircraft to do so.
It was a major blow to the Boeing KC-46 Pegasus, which the US government chose over the Airbus A330 MRTT as the Air Force’s next refueler.
For its passenger jets, though, Airbus states the tech won’t replace pilots in the cockpit but will make flying safer by helping reduce workload.
