Whereas the known limitations of human beings don't cost lives?

Here's an interesting article on the possible impact of automation on the US trucking industry - how long before we're replacing 'truck' with 'plane' and rehearsing the same arguments all over again?

Personally think it's so far out that we really don't know what the world will look like. I don't expect my career to be threatened by it and I have another 20 years left.

Musician 11th Oct 2017 13:04

yellowperil, it's not the limitations that cost lives (well, they do, too, sometimes), but the discovering of them. The more you rush into this, the more limitations you're going to discover rather than anticipate--in a situation where you can't just stop the vehicle and wait for help.

One known limitation: we already know that humans need some time to get their bearings when entering an unfamiliar situation, so when a plane calls a remote pilot for help, that better be some minutes before pilot input is needed: but if the plane is going to try and anticipate that, there are going to be a lot of false alarms, which are going to lead humans into treating alarms as not so serious.

The unexpected challenge in avoiding accidents with the Google car has been to prevent other cars from hitting it: it needs to conform to human expectations when moving in traffic, or a fender-bender can result. If you do not research beforehand how automated planes can intermingle with traditional aircraft in congested airspace, you're going to have some avoidable accidents.

Before we know of the limitations, can we really make an informed decision on whether it's worth it? You can dodge the question by saying "it's going to be inevitable", then you don't need to have a discussion on the merits; but you could be making a bad choice. (Well, it won't be bad for the tech companies driving the change--their bottom line is going to be assured.)

No flight crew
 
I'll fly in an unmanned aircraft when the CEO of the airline will sit in the adjacent seat.
Not just once, but everytime.

Heathrow Harry 11th Oct 2017 17:04

why does it have to be a new design?

It's all an issue of integrating the current electronics and sensors TBH and the decision taking software in the black box -

It'll probably be the 737-5000

Piltdown Man, you are of course right that many incidents have been averted by action on the part of the crew. However if that number is matched by the number of incidents caused or contributed to by the crew, then we are no better or worse off than in a robot airliner.

Mathfox, The saving of 100kg is a bit of an underestimate. Once you take the pilots out, you can get rid of this little lot:
instruments
cockpit controls
switches
armoured cockpit door
flight crew rest compartment
pilots' seats
pilots' luggage
pilots' oxygen supply
all air ducting
all cockpit glazing
windscreen wipers

In other words, strip the cockpit out completely and there is room for another two or three rows of seats. What's more, the area currently occupied by the windscreens can now be the most aerodynamic profile possible, which has got to save a good few tons of fuel each year. Eventually, unless passengers can be persuaded to pay a premium for a view out the front, all airliner's cabins will be like the lower deck of a 747.

If its a cargo aircraft, you won't need the toilets or galley either, unless carrying racehorses and their stable hands, and the latter can probably use the straw like their charges anyway.

Lookleft 11th Oct 2017 23:24

Mechta you are making a lot of false assumptions to support your argument.

No-one knows how many incidents have been prevented by the crew. You would have to go through every airlines database of safety reports to determine that. You can't just assume its the same number. There is a reason that air travel is the safest mode of transport and its not just the technology. You also can't just assume that autonomous 2D vehicles can be easily replicated in a dynamic and often volatile 3D environment. People who know nothing about the airline environment often quote that "Aeroplanes are so sophisticated they can land themselves!" True, but in a very limited environmental window and they still can't get themselves into the air automatically. Until software can't be corrupted, hacked or changed then autonomous airliners are just a tech nerds fantasy.

AerocatS2A 12th Oct 2017 06:50

You'd have to do more than go through incident reports. I don't write a report every single time I rescue the aircraft from its dumb automatics.

Heathrow Harry 12th Oct 2017 08:15

Mechta makes some valid points

I'm old enough to remember when the pages of "Flight" were full of navs ,radio ops and engineers using exactly the same arguments now appearing here. If you can't show how many flights you may have saved you have no facts to argue against the bean counters and management both of whom would loveto dump everyone

Musician 12th Oct 2017 09:11

Ironically, some of the improvements that could make autonomous drone flights safe would also make human-piloted flights safer: ILS on every runway, automated traffic awareness not only in the air, but also on the ground, including general aviation.

Lookleft 12th Oct 2017 22:19


I'm old enough to remember when the pages of "Flight" were full of navs ,radio ops and engineers using exactly the same arguments now appearing here.
The bottom line with removing all the other crew HH was that there were still humans on the flight deck. As an example of how a third crew member did save the day look at the accident of the Ansett 747 in Sydney. Despite the FE being confused about the configuration of the landing gear he was the one that prevented the flight crew from trying to go around after the T/R were deployed.

The challenge to the tech heads is can they guarantee that the software required to operate autonomous airliners will be 100% reliable and unable to be hacked into?

Er, can they guarantee today that the pilot is not suicidal, drunk, a control freak, or incompetent?

I'm looking forward to self driving cars. They will make mistakes, but far fewer than humans.

Lookleft 13th Oct 2017 21:37

No, but put any one of those character flaws in the control room on the ground in a control booth, which some are suggesting, then watch the carnage. With software flaws there are no opportunities to correct them before they manifest themselves. Mental health is a society wide issue and amongst pilots it is being addressed. Drunk and drugged pilots are being sorted with drug and alcohol testing and they are being caught. A control freak? You would have to clarify that as to how that leads to an accident. CRM took care of that problem years ago. Incompetent? All walks of life even, software engineers. I am not saying that human error can be completely eliminated but from what I can tell "software glitches" can be just as fatal and fully autonomous in their manifestation and catastrophic results. Where the pilots came in handy were on aircraft such as the MAS 777 and QF 330 off the coast of Western Australia.

ExXB 14th Oct 2017 08:14

So don't look for 100% guarantees.

AerocatS2A 14th Oct 2017 10:04

It doesn't need to be 100%. Technically it just needs to be better than people, but I suspect that won't be acceptable to the public and a significant improvement will be required.

Heathrow Harry 14th Oct 2017 20:18

The rise of automation in aircraft is very much part of the amazing drop in accident figures even tho' the number of flights has (ahem) soared....

Personally I'd prefer a pilot but I suspect there'll be few on main-line passenger flightsin 50 years time

Heathrow Harry 15th Oct 2017 07:44

One thing we haven't touched is that many airline managements seem to actively dislike their flight crews. Just look at the way they treat them..... Clearly viewed as grit in the operation.... arguing, moaning striking, need constant management (time and holiday allocation), training and RETRAINING....,sim costs, pensions......

Then just think of those lovely, quiet, obedient machines. Buy it and that's it... even updates itself...... and the bosses can concentrate on screwing cash out of the SLF and their bonus package......

I said 50 years...... maybe 20 will be more accurate........

PAXboy 15th Oct 2017 12:51

The way that modern (so called) management treat their pilots is the same way mgmt treat staff in most other lines of work. over the last 25/30 years the 'cut everything to the bone' 'shareholders first' 'my bonus next' 'staff and customers nowhere' has become the normal process.

In due course, the cycle will move on but not soon.

ExXB 15th Oct 2017 15:44

Paxboy. If it does move on it will only be to change the order. It will be 'my bonus first', shareholders - whatever, staff and customers - what are those?

KelvinD 16th Oct 2017 06:37

Hmmm. Take a look at the Ryanair thread here:
http://www.pprune.org/rumours-news/6...-runway-7.html
If so many pilots are unable to agree on how to successfully drive a 737 and where and when to actually take off, what chance a computer getting it right every time?

Heathrow Harry 16th Oct 2017 08:25

that is the point of ourse "so many pilots unable to agree"

A machine will do the same every time........................

Well, about 100%, if it has been programmed correctly.

Musician 16th Oct 2017 16:15

Assuming the environment doesn't violate the assumptions made by the programmers.

PAXboy 16th Oct 2017 17:18

Yes, my first thought was 'Sudden rain squall that contaminates the runway'. But the landside human responsible (be it local for a remote airfield or at a large hub) will then tell the computers about the change in take off / landing parameters and the contamination and it'll all be wonderful. :8

Heathrow Harry 17th Oct 2017 10:59

It'll be automated - pick it off from an automated electronic ATIS system

And sensors wiil check you ARE accelerarating/de-accelerating properly

T250 17th Oct 2017 14:18

Ah yes, the ATIS with the AUTO-METAR such as in use at Heathrow, spewing out '///CB' whatever the hell that is? Never any CB around, yet always published.

Musician 17th Oct 2017 14:53

So you don't actually need to hack the drone to bring it down -- it's enough to hack automated weather information or its sensor system.

Heathrow Harry 17th Oct 2017 15:09

Thinking about it I can see the pressure coming from 3 directions:-

1. The military are already looking at drones/unmanned aircraft to deliver supplies over significant distances - that will no doubt include R&D against hacking...... and if they can do it?

2. Amazon etc are looking at delivery by drones - so that leads to scaling up - packages, then van loads, then truck loads......

3. Airline management want a more uniform, controled and lower cost operation

It's going to happen I think - and maybe sooner than we expect......... after Mr B introduces the MoMA it's going to be hard for airframers/engine manufacturers to keep reducing costs by 15% per design iteration and single manned/unmanned will be an obvious way forward

Musician 17th Oct 2017 16:16

"looking at delivery by drones" makes for good PR, doesn't mean it's going to happen, or that it's even close to ready

Heathrow Harry 18th Oct 2017 07:49

well it's in trials.................

AerocatS2A 18th Oct 2017 10:40

Flying cars are in trials. Just because something is in trials doesn't mean it is close to being a reality (doesn't mean its not either of course.)

No, what humans want is not to be held hostage by other humans having an argument with another human and themselves becoming a casualty.

e.g. train driver and employer in dispute - its the travelling public who suffer the most inconvenience and they are not a party to the dispute.

Automate train operation like the vast number of metro's in the world and thats one more self-entitled, overpaid train driver put of the loop.

Although like you, I doubt that aircraft will be fully automated in this century as a train can coast to a stop safely in most circumstances whereas the end state for any significant aircraft failure is 'death of passengers'.

Conclusion:

Many have written on this topic because they see the technology taking off. They see the progress in the technology that many have made and assume that drone delivery will be allowed soon. They get the “West Coast” mindset where they think if enough money and technology are thrown at the problem, it will be fixed regardless of the law. Additionally, most writing on or marketing drone delivery do not understand all the legal issues.

Aviation is an “East Coast” industry where the laws out of D.C. will heavily influence the business. Aviation is an extremely regulated environment. The faster the companies operating in this area realize that fact, the better off they will be so that they can actually do these types of operations.

Amazon still has a long way to go before drone delivery can be experienced in real life by the American public, not just as a short clip on the internet.

most humans want a flight that's as cheap as possible IMHO

Most humans have never set foot in an aeroplane, nor will.

The world need a buss-sized drone that can replace short flights, specially for transport across water. A passenger drone travelling around 200 km/hr could easily outcompete commercial airlines where flight time for a jet is 1 hour or less due to a drone could take off and land from small spaces near a parking lot with more convenient locations than an airport.

I see a drone with:
- About 4 electrically driven propeller pods each side of a bus shaped body.
- 2 petrol engines to create the power, with separate fuel tanks for security.
- Batteries to boost power at takeoff and enough capacity to land safely if engines cut out.
- Each side would have separate controls for 2+2 pods, so if 1 set cut out the drone could still land safely.
- If landing on water the whole unit would be kept floating by airbags.
- Completely automated flight but a single attendant for safety and to control that eveybody has a ticket and handle unruliness.
- Remotely but cable connected pre-programmed flight destination to avoid possible hijackings.
- Flight controlled by gps, safety by radar and lidar.
- Laser based ground scan to find safe emergency landing spots.
- Around 50 passengers per drone for versatility and about 5-7 tons payload.
- Price for each unit would need to be in the Euro 500k to 1 million bracket to be competitive.

Public interest and safety would be satisfied by the buss-drones beeing owned by regulated entities, and production and maintenance could be strictly controlled. A separate commercial drone-buss flying zone could be regulated for around 500-1000 meters above ground level.
A nicer interior "private jet" version of the drone could be developed to replace helicopters and increase the market. Commuter routes into traffic congested city-centers is another market.

Heathrow Harry 20th Oct 2017 07:26

Short flights are only attractive if you can essentially turn up and go - as with a car or a train. When you have to arrive 90 minutes before the flight and go through all the security hassle they become unattractive. Plus of course the airport doesn't make any money unless they can trap you in the shopping arcade

Short range Bus Drones might work but only if they can operate like a bus - ie independent of large fixed airfields, security etc etc

...and production and maintenance could be strictly controlled.

The size together with the production & maintenance requirement appear to contradict the price bracket. For example, have a look at the new cost of a 53 seater coach (Euro 300k+).

The problem with quadcopter-type drones when scaled up, is the velocity and noise of the downwash. When V-22 Ospreys were sent to help after the Nepal earthquake, they were rapidly withdrawn when it was found their downwash just added to the destruction.

So operate them over water only.

Now there were those things with downward-directed airflow operating over water that you don't much see any more except where the situation demands amphibious operation... ah yes.. hovercraft. (Top speed is ~150 km/h). They were commercially viable across the English channel until the tunnel was completed.
