A350-1000 autonomy tests aimed at supporting dual-pilot cockpit: Airbus

By David Kaminski-Morrow13 January 2023

Airbus has trialled further autonomous flight concepts using an A350-1000 test aircraft, including emergency diversion and automatic landing, but insists they are aimed at supporting a dual-pilot, rather than single-pilot, cockpit.

Part of the airframer’s UpNext initiative the ‘DragonFly’ programme takes its inspiration from insects of the same name – using biomimicry of dragonflies’ combination of high-speed senses, spanning a wide field of view, feature recognition and precision flight control.

DragonFly has focused on three particular aspects of autonomous operation – diversion, landing and taxiing – including assistance during a simulated incident of pilot incapacitation.

The aircraft relies on automatic intelligent decision-making based on flight data obtained through a combination of sensors, including cameras on the A350’s nose, and backed up by vision algorithms and guidance calculations.

DragonFly head of demonstrator Isabelle Lacaze says the programme has been running for two years, but flight-testing using aircraft MSN59 commenced in July 2022 and the airframer is “enthusiastic about the first promising results” obtained towards the end of last year.

Among the achievements, she says, was the simulation of sudden pilot incapacitation over Limoges during a flight to Lyon, in a real air traffic environment.

“The system took over and diverted the [aircraft] safely to the nearest appropriate airport – Toulouse in that scenario,” says Lacaze.

“It was really amazing to see that all our stakeholders in this scenario [including test pilots and air traffic controllers] were really positive about the feasibility and the acceptability of the solution.”

She states that the diversion function can activate automatically or act as a support to the pilots.

Cameras mounted on the A350’s nose are part of the sensor array to gather external situation data

Addressing the possibility of incapacitation remains one of the contentious issues when considering a possible shift towards single-pilot operations.

But Lacaze insists that DragonFly is intended to develop and evaluate assistance to a two-pilot crew, to help manage workload during intensive phases of flight, such as diversion – with cases of incapacitation or medical emergency among the possible causes.

“We consider there is already huge value [in this],” she says. “We are in exploratory field of research. Our framework – to mature, to explore, see what we can do with the new technology – is really focusing on… assistance for dual-pilot operations, meaning the current crew composition.”

But DragonFly does envision support for extreme circumstances in which pilots are no longer able to control the aircraft.

The criteria for detecting incapacitation are “sensitive”, says Lacaze, and she does not elaborate on the techniques involved, but says that the system is designed to take over “seconds” after detection.

Lacaze says the DragonFly demonstration team has had to “fine tune” the implementation through a step-by-step process, gradually integrating different aspects, to ensure that safety was preserved as the aircraft took control. “It was not an easy walk in the park,” she says.

She says the programme is intended not only to offer diversion assistance but to support crews in taxiing at congested airports, through computer-vision obstacle detection, to maintain speed control and centreline tracking, as well as alerting pilots to the risk of runway crossing. The taxi functions have been tested at Toulouse airport.

DragonFly also used vision systems to support taxiing assistance

Prior autonomous flight testing using an A350-1000, under a programme named ATTOL, demonstrated a fully-autonomous take-off using vision systems to track the runway, and carry out automatic rotation.

DragonFly has extended this to automatic landing, including in low visibility conditions using sensors and vision systems, and Airbus believes the capability could be broadened to approaches to any airport, even those not equipped with the ground technology to support landing automation.

Airbus says its demonstrator takes into account a range of external factors – including terrain, weather and military flight zones – as part of its assessment of where to land, and generates a new trajectory.

It adds that the aircraft also uses constant communication with air traffic control and the airline operations centre to co-ordinate a safe approach.

Several Airbus divisions and a number of partner companies, including Collins Aerospace, Honeywell, Thales, Onera and Cobham, have co-operated with the DragonFly programme, which has embarked on its last three months of testing.

“These tests are one of several steps in the methodical research of technologies to further enhance operations and improve safety,” says Lacaze.

She says the UpNext initiative is launching a project to advance landing and taxi assistance with a view to taking advantage of new-generation computer-vision algorithms.

Is this the software developers having run out of ideas for yet another feature?

Isn't it already doing automatic TCAS maneuvers and emergency descents?

Less Hair 19th Jan 2023 12:53

It sounds like that Garmin general aviation autoland feature scaled up to airliner sized aircraft. This will be what the new push button at door 1L is for.

No , it is how Airbus works, it let their brightest engineers develop new ideas and support prototyping. Not all their bright ideas or prototypes are kept , look for instance at the 2 or3 urban previous VTOLs, or their 2 electric aircraft, in each case a prototype was build, flown then abandonned.
Dragonfly here is another of thsose , but the long time aim is autonomous aircraft for sure. Wether some of hese features will see production , will it be standard or as an (expensive) option , time will tell.

As Less hair said the basic technology already exsists, ( Garmin for the auto diversion / land and Gulfstream for the recognaissance cameras ) putting iall this into practice and having it certified for a 300 seat aircraft will be the challenge I guess, But you have to admit it is very interesting .

Airbus is right to research such things and, remember, in all R&D there will be some projects which reach dead ends and some which will open up unexpected avenues.

However, while I don't think we will see pilotless airline operations in the near future, I do think it will be possible, in the not too distant future, to design and certificate aircraft for single pilot operations in the cruise so that, on very long flights, it would be possible either to reduce or even eliminating the need for 'heavy crews'. This would enable one pilot to take his statutory rest while the other is left alone at the controls. There would then be no need, depending on the length of the flight, to roster extra pilots.

You could then have, on ultra long flights, two at the controls for take-off and landing but only one at the controls during the quiet parts in the cruise with the other readily available in the crew rest area - much like the watch system at sea. I am sure this could work and would offer substantial financial benefits to the airlines.

It would also allow for co-pilots to be trained and to build up sufficient experience so that they could take sole control in the cruise. In practice, I think there would need to be an extra co-pilot or apprentice pilot period (call it what you will) for a long time until the necessary experience has been gained. Experience is not something that is acquired quickly and takes several years. As we all know, good piloting skill is not just about flying the aircraft but also about knowing what situations to avoid.

Finally, I think that long solo duty periods would be so ruddy boring I doubt any sensible person in their right mind would ever want to do the job. I know I wouldn't!!

Two guys are needed to talk to each other so one can learn from the experiences of the other guy and see how things are done.

For sure this is the type of feature that could help in the event of an incapacitated crew or nefarious forces

As long as it is used for things like that, and nothing further. I've always liked Airbus for what they're doing with technology. Hopefully they don't consider using it to remove the humans who are meant to fly it.

Autonomous & automated flying is coming, sooner or later, for the better or the worse. These are all small steps in that direction.

Kennytheking 22nd Jan 2023 14:00

Airbus today suffers from a LOC* anomaly where it sometime cannot properly capture the localiser. This is something aeroplanes have been doing for, like, 90 years and Airbus still can't get it right. I'm not too sure that their autonomous project is going to pass muster.

Never happen, pilot error would just be replaced with errors in software code and architecture design of the black boxes, we've had an A320 that was written off because the black boxes wouldn't allow the crew to flare for the landing, an A330 that did its best to crash the aircraft, and a 777 out of control because the black boxes had a failure that wasn't supposed to be able to occur. Thank God in all cases there were two aviators in row 0 who knew their business.

KRviator 23rd Jan 2023 01:32

And how many times have those humans - because they sure as hell weren't 'pilots' yet alone aviators - flown perfectly serviceable aircraft into a hill, an ocean or elsewhere because they screwed up, yet alone committed suicide and decided to take their passengers with them?

You've cited three examples of tech errors, and I'll grant there are likely many more - but "pilot error" outstrips technological failure especially these days, by an order of magnitude. A computer isn't going to shut down the wrong engine, like the crew did at Kegworth or Taipei. A computer isn't going to fly a 777 into a sea wall on a CAVU day that my 10 year old can (and does) land in and a computer isn't going to panic and hold full back stick while falling 35,000' into the Atlantic. There'll be new and novel failures but they'll still be rarer than the number of crew-induced errors today.

That being said....What scares me about the pilotless airliner is the same thing that scares me about those robot trains around the world. I'm paraphrasing here but, there are known unknowns - things we know we don't know, and there are unknown unknowns - those things that no one knows they don't know. And those are the things that are going to limit the introduction and deployment of autonomous airliners, because "It's not supposed to do that" doesn't cut the mustard when things go pear shaped in the flight levels.

Just picking a year at random 2019 there were 12 crashes with the loss of 261 lives, 157 of those were the Ethiopian MAX. I very much doubt pax would accept no crew, I certainly won't, particularly with QF 32 in mind.

WIth more reliable autonomous aircraft when it has already proved it's reliability for cargo operations it will be accepted, especially with significant price difference. Indonesian max on an earlier flight was landed safely by acting differently. But this time MCAS completely confused the pilot. So two humans in front reacted differently to the situation at different time. So it will be a matter of what makes you more uncomfortable the machine or the man.

The Ethiopain MAx is probably not the best example to take, there are still a lot of knowledgeable people out there that believe that had the crew followed strictly the new MCAS poscedure the aircraft would not have crashed. aAfully automated aircraft would have followed the procedure, cannot be programmed otherwise.
But to be even more the Devil's advocate. let's take the latest incident covered here : the AA near ground collsion at JFK. Had AA been fully automated , the ATC computer would have instructed dep 4L. cross 31L at K, and the aircrfaft would have just followed that and not end up crossing 4L. But that said. when dealing with full automation ( and ATC my line of work we have the same debate ) I keep on reminding engineers one of the good old Al Wiener law : "

Whenever you solve a problem you usually create another one. You can only hope that the one you created is less critical than the one you eliminated."
Fully automated aircrfaft will have their own issues . It won't be easy , and it will take time . But one day . especailly after a big pilot blunder taking many lives.. who can say never..?..

Mankind isn't ready for autonomous cars - and such cars are not ready for mankind

So is ATC to be fully automated too? No reason to think human ATC is safer than human pilot...

ATC and piloting will eventually be fully automated. Obviously a very long process, fraught with valid and irrational issues. But assuming a continuation of our technological civilization it will happen withing the next 20 to 50 years.

So the fact that 25% of people are still wearing masks in airports in 2023, suddenly these brave, intrepid, pax will board an airliner with no pilots? And I’ve stated this before, if my company wants me to fly a single piloted airliner, I will ask for my current salary, plus my F/O’s current salary, plus a bonus for the additional responsibility that will fall into my lap…So where are the cost savings? And safety enhancements?
