Britten-Norman Pilotless Planes
 
https://www.thetimes.co.uk/article/b...2030-rw3mw3blb

Brace yourself for pilotless planes by 2030

Pilotless passenger aircraft will take to the skies within a decade under plans drawn up by a British manufacturer to cut the cost of flights.

Britten-Norman, based on the Isle of Wight, said yesterday that it planned to introduce single-pilot planes with an “autonomous co-pilot” by 2025. It said that the shift to fully pilotless planes could be achieved by the end of the decade, giving operators the choice to move between “uncrewed and piloted” flights as required.....

Yesterday, Britten-Norman, the sole independent commercial aircraft manufacturer in the UK, announced that it had signed a deal with Blue Bear, a British autonomous flight specialist, to develop the technology.

The two companies will work to automate Britten-Norman’s Islander, a twin-engine utility aircraft which is used for passenger flights, cargo and search-and-rescue operations. The project is due to be launched this month.

The plane, which can carry up to nine passengers, and has a short take-off and landing capability, operates on commercial routes between Scottish islands.

The team behind the project said: “Eventually the system will allow the Islander to take off, fly and land without any human input but the first milestone will be an automated co-pilot which can advise its human operator.”

Passenger jets have been flying on autopilot for around 50 years and large drones piloted from the ground are common in the military. However, pilotless passenger planes are not permitted. The technology would ultimately have to be approved by regulators.

Britten-Norman already produces aircraft that are certified for single pilot flights but some operators elect to, or must, operate with a second safety pilot. The company said that the ultimate goal was optional full automation which “should be realised within this decade”.

It said regional air transport was often “underdeveloped and often forced to rely on subsidy. This is because regional air transport can struggle to be economically sustainable due to high operating and maintenance costs,” it said. “Regional air transport will have to incorporate zero carbon and autonomous technology to make operations affordable and scalable.”......

CRM could be very interesting.

Lookleft 7th October 2020 07:42

Yawn here we go again. Can you keep us appraised when the mighty Islander has done a fully autonomous assymetric takeoff and a two engine landing in 30 kts of crosswind. When it can do that 100 times out of 100 then I might be interested.

Rie 7th October 2020 08:11

If memory serves me correctly at least the computer only has to remember 65kts for everything...

CAEBr 7th October 2020 08:15


When it can do that 100 times out of 100
Right idea, but any regulator is going to start with something more like 100,000 times out of 100,000 and ramp it up from there.

The control law has never been the issue for autonomous flight. There is no reason that an autopilot cannot consistently carry out an on-limits crosswind landing as well as a top class pilot on the top of their game.
The complexity comes from interfacing to, and acting upon every conceivable problem from every system involved in the flight. And that includes external "systems" such as ATC.

Crosswind landing with a fully functional aircraft? I am fine with that.
Carrying out all the correct procedures to deal with an engine fire - not so sure.

Perhaps I'm being daft, but i don't understand how removing one (or both) pilots will have any real impact on the overall operating and maintenance costs. What's the pilots salary as a percentage of the overall cost of operating flights? Or do the extra tea and biscuits they need to carry push them over the edge on profitability? It's not like you can remove one of the engines because there isnt a pilot on board...!

The only exception to the above is it, rather than having a cockpit at the front you can actually have 3 or 4 rows of extra seats. Perhaps charging a premium for a nice view (i'd pay extra for that!!). But wouldnt there be a load of wasted space as at some point the fuselage needs to taper down to a point...?

How things have changed! I managed to fly both Islanders and Trislanders without advice from an ‘autonomous co-pilot’🤔😳

Large numbers of old Antonov An-2s are converted to drones and used in a certain recent conflict to one way carry explosives or to trigger enemy air defences to activate.This might be all that is feasible today.

Not a pilot, but can I ask why you wouldn't trust automation to carry out correct procedures in any situation? I would have thought that the problems would come in the situations where there are no pre-defined correct procedures, perhaps where the only choice is the lesser of two evils, or in those situations where current automation gives up and hands the aeroplane back to the pilot. Check-lists and SOPs, I gather, are responsible for a lot of the improvement in safety; is there a way in which even SOPs have to be performed with human-only nuance? (A real question.)

cattletruck 7th October 2020 09:32

Thanks to Covid-19 there are already plenty of pilotless planes.

Yet another puff piece. Meanwhile in my neck of the woods, a locomotive driver discovered his computer controlled sand dispensing system failed completely during wet and greasy track conditions yet he struggled to pull the train to a stop after going through two uncleared level crossings and a curve well above the track's safety speed - with only minor injuries to a passenger.

WhatShortage 7th October 2020 09:57

It has taken boeing like a year just to "fix" a program and a few other issues in an airplane which is handled by humans and you're saying that there will be pilotless ( which means more complications) in less than 10 years, yeep, sounds accurate.

macdo 7th October 2020 10:28

IMHO the general public won't accept the idea of a pilotless passenger flight until the successful adoption and proving of autonomous cars which will normailise the idea of automation in their minds.
The BN idea above is just a glorified autopilot on an a/c that is really single pilot anyway. No news here, move on...

Not a problem. ”George” will be your PIC and you’ll hear ”Your controlls” every time George think its hard.

About 20% of airlines costs on pilots.

Tarq57 7th October 2020 17:36

Such negativity.
The proposal will prevent about 50 cases of hearing loss, worldwide, every year!

ChrisVJ 7th October 2020 18:14

Seriously, Pilots cost 20% of airline costs?

Amortisation of aircraft and aviation equipment,
Cabin crew
Ground crew
Servicing and spares
Airport fees
Insurance
Head office personnel, management
Head office overhead
Fuel, oil etc
Agency commisions
Advertising

Edit: And taxes

I am sure this is not an exhaustive list, and I keep hearing on here how poorly LOCO pilots and entry level 1st officers are paid and how they now have to pay for their own upgrades.

Tesla are coming out with an autopilot which will cope with suburban street driving. This is a far more complex, uncontrolled and random environment than aviation.
As for 30 kts of crosswind? The autopilot can easily do it with more precision than any human. Likewise engine failure or anything else you care to throw at it.

Until recently, autopilots didn’t have “eyes”. Not so anymore. Image processing and AI have leapt forward in leaps and bounds. We have moved on from when the Century III was the pinnacle of technology.

Also note that Garmin now have a $250K option for their autopilots on the new Piper Meridian - a large red button which tells the A/P to land at nearest suitable airport in case of the (frail) human pilot becoming disabled. A/P does it all including configuration and selecting gear down and neither does it need a Cat 3 ILS to land the aircraft.

The good old days of steely eyed pilots in leather flying jackets being an essential part of air travel are coming to an end.

Your airliner of the future will be controlled from a repurposed call centre in Mumbai.

Let's see how a pilotless BN2 can cope with the weather & airstrips in Shetland. I flew there & I just don't see automation technology being anywhere near having the ability, robustness, and adaptabilityin those sorts of places.

Pilots ~5% give or take.

You're not a pilot then. If an autopilot can do 30 kts with more precision then why are they limited to 15kts crosswind for a routine autoland? Tesla still put 2 astronauts in spaceex Dragon. There is a reason why, despite all the advances in technology, that airliners still are not certified for auto take-off.

George Glass 8th October 2020 03:35

Yawn.

Who liaises with Operations / Airport staff / Flight Attendants / Ground Engineers / clearance delivery / ATC / Met. Department etc. etc. ?
Oh , that would be a Pilot.
The delusion behind all this is that all a Pilot does is manipulate the aircraft.
The only people enthusiast about this are those that have never operated an RPT jet.
It isn’t happening anytime soon.

I don't know for other operators, but for my operator, we switched to competency based evaluations years ago.
The competencies "procedures" and "decision making" involve : "knows how and when to deviate from standard procedures when safety requires so"
Not being able to do this results in an "unacceptable" mark.
People were kicked out of training at some points because they were unable to deviate from procedures. For example one guy refused to put the gear out before flaps 2 and after flaps 3.

So an autonomous aircraft would also be required to deviate from what it was told, in safety requiring conditions.

Exactly.

Let's just hope that artificial intelligence is not already able to do this.

For a large airline, 20% is the cost of the total staff, including cabin crew, ground crew and office teams..
Pilots may represent only a quarter of that so maximum 5% of the cost of an airline.

ShyTorque 8th October 2020 12:32

:E

Fully autonomous aircraft will obviously need a backup system.
I can imagine the situation with "George and George" in control:
"You have control....BEEP!"
"Negative....BEEP!"
"BEEP!"
"BEEP!"

Well, as ASO said back at Post #2, BAE Systems have been fiddling about(:p) with their autonomous Jetstream for some years now. Last I can find on it is https://www.baesystems.com/en/articl...flying-testbed from 2016.

I guess the only advantage of the Islander is that, even in the most sound-proof cockpit, the other crews would detect the Islander coming from miles off without even needing TCAS!

Ironic it is an Islander being used for an autonomous aircraft trial as it's the best fun flying I've ever had! Took off limited fuel on a ferry flight in a "rather stiff headwind" once - which rather confused ATC! They made the silly mistake of looking for me along the normal departure path and had to ask me where I was ....... :}

Went up almost like a Saturn 5 ...................... just a lot noisier than a Saturn 5!!!! :ok:

Happy days! H 'n' H

In principle I would agree.

In practice, I would suggest that 3-axis control law is a precise art and thus autopilots can fly with a precision difficult for humans to equal (consistently anyway). But complex decision making under complex failure conditions is not the same sort of problem to solve. It can of course also be automated, after all that is what emergency checklists are trying to achieve. However, you do need to be sure that you have covered every possible eventuality in the software. You also need to provide the autopilot with actuators for pretty much every lever, button, switch and circuit breaker in the aircraft. And when you accept that then you begin to wonder if retrofit of an existing aircraft design is really an option.

As for the engine fire scenario, just as an example: Shut down and land soonest procedures may be easily automated - but deciding the fire is not contained, structural integrity is at risk and we have to ditch now - that's a much bigger judgement ask for an automatic system.

So basically I do not think we are there yet.

Comparison with Tesla autodrive vehicles is of limited validity, because those autopilots always have the option to simply stop the car when it all gets a bit too much.

Apart from various Trials a/c based on existing hardware (modified), like you, I'd suspect there would be a whole new design philosophy associated with autonomous flight - your autopilot would be an "aviation platform management and control system" - a whole generation forward on from today's best "autopilots/FMCs" so I'd not expect to see retrofitting of existing airframes to be a way forward either. Switches, buttons and levers will be a thing of the past as there would be no-one there to push/pull/prod them. In a way we are talking of a "Wright Brothers" type leap forward in terms of technology, legislation and social acceptance etc, etc. Proof of concept work by BAE, B-N and others is just one part of that evolution/revolution.


....... As for the engine fire scenario, just as an example: Shut down and land soonest procedures may be easily automated - but deciding the fire is not contained, structural integrity is at risk and we have to ditch now - that's a much bigger judgement ask for an automatic system. ......
The scenario you have used may continue to use human intervention on the ground to make that decision and to command the a/c to do something like ditch rather than divert. You'd have almost as much data as you do today from your downlink to make that call - you'd just not be able to use the P2 to nip aft to take a look first! OK, slightly flippant that but you see what I mean. But you'd have video links and such like (even cabin crew?) to assist you. Even your smoke detectors would probably undertake chemical analysis of the smoke and suggest what is smouldering/burning. So, what you'd probably have are "supervisors" on the ground; one person monitoring several flights at any one time but on hand to address situations like you cite.


....... So basically I do not think we are there yet. ......
Quite agree ........ but that's not saying we won't end up there one day as quite a few seem to say. Lets face it, you just have to look up some of the fears that were held when trains first arrived. Those who say "never" may well be correct in the short/medium term. But "never ever"? Mmmmm, a bit Victorianesque!

Would I like it? My main personal reservation is not having someone in control who would arrive at the scene of the accident a few milliseconds before I did as I feel that does help concentrate the minds of those i/c. That said, humans often put themselves into trouble with great panache so that sort of evens the equation up a bit! We've all had those situations when, after a "moment" has happened I've sat back and thought "Mmmm, not your brightest idea that, H 'n' H. Better get on and complete this flight as the pax are sort of relying on you here!".

Will it happen in my lifetime? Military - well, one could argue that we are simply increasing our use of drones which started in 1849 and the use of drones in warfare has now become routine; just another "tool of the trade" of killing (I'm ex-Mil btw). Some cargo? Almost certainly. SLF flights? Probably not in the few decades I may have left ahead of me. But it may be closer than I think. I suspect the biggest hurdle will be the seamless transition from today's airspace environment to an autonomous one.

Interesting times to be sure! H 'n' H

Oh I don’t know. It’s an Islander. Just how hard is it to blow out the candles?

733driver 9th October 2020 07:52

I don't think manipulating the controls is the big problem. I also don't think automating any established normal, abnormal or emergency procedure is the big problem. Neither is configuring the aircraft automatically.

The real challenge is that on most airplanes I have ever flown the abnormal and emergency procedures are far from perfect. On the 737 I thought they were really good in almost(!) all situations I encountered in the sim over the few years I flew the type.

However, most biz jets I have flown there was a lot of room for improvement in the checklists including some obvious mistakes that the manufacturer was very slow to address if at all. I would not want to sit in the back of a plane where a computer is just actioning these kind of imperfect procedures. And that'a before we get into other variables and complexities such as multiple failures, related or unrelated, weather etc.

And what about emergencies such as fire and smoke on board (not engine fires) and medical emergencies? I have had GPS jamming on an aircraft that had no INS/IRS. The DME/DME back up did not work as advertised and the FMS reverted to DR which resulted in a huge map shift in a very short time. How would the automated pilot deal with that?

Yes, the Garmin auto land available on some single pilot GA types today is quite impressive but I am sure it is very far from being able to replace a real pilot day in and day out. It might save the day when the sole pilot of a small plane becomes incapacitated but that's a much lower bar to clear than providing safe transportation in all conditions for billions of passengers on millions of flights every single year.

Not saying it's impossible. The technology is there in principle but it is not nearly ready yet and many years from being implemented widely in my humble opinion. What's needed is true AI which can only work if it has all the inputs (sensors) we have plus the interface in place to interact with it, including input from ATC and mx on the ground, from cabin crew etc.

Case in point
 
It has been a while since the pilotless aircraft debate raged on this thread, but the recent KAL incident brought it to mind:

https://cimg5.ibsrv.net/gimg/pprune....d8446d865.jpeg

Thankfully no serious injuries were reported. Amid speculation (in the Accidents & Close Calls forum) regarding the precise circumstances leading up to the overrun, I’m surprised there hasn’t been more discussion about how the crew eventually managed to get the plane to stop. At risk of leaping to conclusions based on nothing more than a photograph (see above), the evidence does suggest it went something like this:

https://cimg7.ibsrv.net/gimg/pprune....df6ee862a.jpeg

If my theory is correct, then it provides a timely reminder of the important role human beings continue to play in the cockpit when unusual and unforeseen circumstances arise. Moreover, I’m not sure a single pair of feet would’ve sufficed on this occasion – this one looks like it was a real ‘four-legger’ (as I suspect this type of close-call will come to be known).

(Despite the tongue-in-cheek observation, there is a genuine point being made here - especially if it turns out that the overrun was related to a fault with the aircraft)
