Artificial intelligence (AI) transition

There’s much that has been written on this subject. In fact, for a non-specialist observer it’s not so easy to get to grips with the different predictions and views that are buzzing around.

There’s absolutely no doubt that Artificial intelligence (AI) will change every corner of society. Maybe a few living off-grid in remote areas will remain untouched but every other human on the planet will be impacted by AI. Where there’s digital data there will be AI. Some will say this brings the benefits of AI into our everyday and others herald a pending nightmare where we lose control.

Neither maybe totally on the money but what’s clear is that this is no ordinary technological transition. Up until now, the software we use has been a tool. Built for a purpose and shaped by those who programmed its code. AI is not like that at all. It’s a step beyond just a tool.

Imagine wheeling a hammer that changed shape to suite a job, but the user had no control over the shape it took. How will we take to something so useful but beyond our immediate control?

In civil aviation, AI opens the possibility of autonomous flight, preventive maintenance, and optimal air traffic management. It may work with human operators or replace them in its more advanced future implementations. Even the thought of this causes some professional people to recoil.

I’ve just finished reading the book[1] of a former Google chief officer, Mo Gawdat and he starts off being pessimistic about the dangers of widespread general AI. As he moves through his arguments, the book points to us as the problem and not the machines. It’s what we teach AI that matters rather than the threat being intrinsic to the machine.

To me, that makes perfect sense. The notion of GIGO[2] or “Garbage In, Garbage Out” has been around as long as the computer. It does, however, put a big responsibility on those who provide the training data for AI or how that data is acquired.

Today’s social media gives us a glimpse of what happens when algorithms slavishly give us what we want. Anarchic public training from millions of hand-held devices can produce some undesirable and unpleasant outcomes.

It maybe that we need to move from a traditional software centric view of how these systems work to a more data centric view. If AI starts with poor training data, the outcome will be assuredly poor.

Gawdat dismisses the idea that general AI can be explainable. Whatever graphics or equations that may be contrived they are not going to give a useful representation of what goes on inside the machine after a period of running. An inability to explain the inner working of the AI maybe fine for non-critical applications but it’s a problem in relation to safety systems.

Turnip

Root crops come in different shapes and forms. In Britain, most of our sugar comes from sugar beets[1]. It’s weaned the country off colonial sourced sugar cane of decades ago[2]. It’s a large home-grown industry that goes on under the radar. Given recent utterances, Government Ministers may not know that it exists.

There are deep cultural themes that are associated with root crops in Britan. Some of this imagery comes from a long history of growing root crops. Some of this comes from the British war time experience of ploughing up every available space for food production. In a time of food rationing the humble turnip played a key role. The turnip, Brassica rapa L., is one of the world’s oldest cultivated vegetables. Afterall they don’t require a lot of attention and can endure hostile weather quite well.

It’s a common myth that we (the British) all eat seasonally. It was mostly the poorer people in a community who had little choice.

My own recollection is of my father unsuccessfully growing a small field of turnips. They will grow in heavy Somerset clay soil but the mess of cultivating them on land that floods is beyond a joke. Machinery gets bogged down and the harvest is more dirt than turnips. I remember that the crop made good animal feed and little else. The field was quickly retuned to a new lay of grass.

This week, Conservative Secretary of State for the Environment, Food and Rural Affairs Therese Coffey told the UK Parliament: “lot of people would be eating turnips[3]…”. This was a government statement addressing empty British supermarket shelves.

Now, I’m not about to have a downer on the poor turnip. They are a bit of an acquire taste but have meritorious qualities and are inexpensive. It’s more the silliness of the Minister’s utterance in the House of Commons that is surprising. It’s a naive exposition that casts the vital subject of food security as a comic game. The Minister doesn’t seem to have a command of her brief.

We all know that crop production can be sensitive to weather conditions throughout the growing season and at harvest. Farmers know that and live that fact. Supermarkets know that and live that fact. Both food production and distribution adapt, accordingly.

The British problem is that the cost of production has rocketed. Brexit and high energy costs have hammered farmers. Former specialisms in agriculture, like tomato production under glass, are not sufficiently supported to remain viable in current condition. In fact, tomato production is not alone in this respect.

What’s clear is that the UK’s Minister needs to get a grip. She needs to understand the nature of British agriculture and stop making foolish excuses.

High ALT

Normal commercial air traffic control doesn’t go beyond 60,000 ft in altitude. That makes sense since civil flying activities have been limited to lower altitudes. In fact, modern commercial airliners are not designed to fly above about 45,000 feet. This is a compromise based on what works commercially as much as what’s works best. Aircraft instruments are calibrated making standard assumption about the atmosphere.

For some of its flight, Concorde cruised at a height of 60,000 feet. More like a military jet, with its speed it had the capability to make use of higher altitudes.

It’s even possible to fly above 50,000 feet without an engine. The world record glider flight by AIRBUS shows it’s possible.

The Earth’s atmosphere is not uniform. It changes its characteristics with altitude. The atmosphere can be divided into five layers, as the temperature and density change. They are named: Troposphere, Stratosphere Mesosphere, Ionosphere and Exosphere. 

The Troposphere is a layer that goes from 8 kms (26,247 ft) on the poles to about 18 kms (59,055 ft) on the equator. This is the layer where weather is experienced.

On average, the Stratosphere goes up to about 40 kms (131,234 ft). The winds blows fast but they tend to be more consistent as they wrap around the globe. The lower portion of the Stratosphere is virtually isothermal (layer of constant temperature). 

A medieval English philosopher and Franciscan friar, Roger Bacon[1] figured out that the air might support a ship in the same way that water supports ships. In the 13th Century that was a nice academic conclusion but little more.

With all the current controversy surrounding high altitude balloons, that the road to flight started with balloons, could be said to be a bit ironic. It’s long been known about that balloons fly well at high altitudes but it’s a new frontier as far as commercial activity is concerned. For science, weather balloons may go up to 40 km to measure the high level winds.

Some experimental work has been done on trying to commercially use the airspace above normally civil flying. The Google Loon trials[2] are an example of an attempt to float a telecommunications platform high in the sky. These balloon trials were abandoned as difficulties proved greater than anticipated.

It’s not so easy to keep a high altitue balloon on-station.

Now, considering the news in North America, maybe high-altitude operations ought to be a matter of regulatory concern. This is not a subject that any one country can address alone.

There is some legal, regulatory and technical work[3] underway in Europe[4] but it needs to make progress. This is a subject for international collaboration.

Rules

Let’s be controversial. Principle Based Rules could be retitled Hypocrisy Based Rules.

Now, I’ve already caused confusion because most consumers, or users of services will not have a clue what I’m talking about. The way rules are put together is not an everyday topic for conversation. Even if, in our complex society, this subject is vitally important.

Listening to the daily news it’s clear there’s been a break down between British Gas and its regulator and some vulnerable customers. Practices undertaken by a British Gas sub-contractor have shocked people. Breaking into people’s homes should not be normal business practice.

Yet, these real-world actions happened, and they sharply go against the “principles” of the energy supplier[1] and its regulator. So, do the rules that exist produce behaviours that fit with public expectations? This is the “how long is a piece of string” question. In other word the perception of the rules, such as they are, can be favourable but when it comes to implementation it’s another story completely.

Sadly, the defensive reactions of both energy supplier and regulator are to frame the whole problem as one of first not knowing then discovery, investigation, and corrective action. This is not bad in of itself, but it’s the most basic kind of reactive response that can be expected. It says to the consumer, we will wait for an influential spokesperson[2] to highlight a failing and then respond to pressure.

Has British Gas captured its regulator? That is to convince them that everything is hunky-dory and maybe convinced themselves it’s hunky-dory too but at the same time not bother to look at customer facing bad practices?

Hence my coining the notion of Hypocrisy Based Rules. I’m not saying for one moment that regulatory rules can be written that have no gaps, inconsistencies, or avenues for “creative compliance”. It can be advantageous to the consumer that an energy suppler has a degree of freedom on how they comply with rules.

What was missing is that regard for the need for constant vigilance. Reports suggest that British Gas’s sub-contractor undertook behaviour that did not fulfil regulatory goals.

Although it’s long in the tooth, this quote from an Irish statesman has resonance:

The condition upon which God hath given liberty to man is eternal vigilance. John Philpot Curran[3]

In this simple sentence “liberty” can be replaced with safety, security, prosperity, and honesty. It’s often been reworked.

Fatal accident in Nepal 2

We are now one week from the fatal accident that occurred on Sunday, 15 January in Nepal. Yeti Airlines Flight 691, an ATR 72-500 aircraft, crashed while on approach at Pokhara International Airport in Nepal

We are now one week from the fatal accident that occurred on Sunday, 15 January in Nepal. Yeti Airlines Flight 691, an ATR 72-500 aircraft, crashed while on approach at Pokhara International Airport in Nepal[1]. Sadly, this accident resulted in 72 fatalities. No one survived. Only one body remains to be discovered[2].

This has been Nepal’s deadliest aviation accident in over 30 years.

After years of pandemic-caused travel disruption this land locked nation was hopeful that their new airport would bring the tourists back. The nation’s second-largest city sits in the shadows of a towering mountain range. It’s a picture postcode setting for this tragedy.

Nepal’s government has set-up a five-member committee to investigate the accident.

As stated in the International Civil Aviation Organisation (ICAO) Annex 13, Aircraft Accident, and Incident Investigation[3], it’s the responsibility of the State of Occurrence to lead an investigation. The objective of that investigation should be prevention of future accidents and incidents. It’s not the purpose of a technical activity to apportion blame or liability.

Nepal is the State of Registry and the State of the Operator, but they must notify the State of Design, the State of Manufacture (France) of the aircraft and ICAO in Montreal.

There are numerous speculations concerning the cause of this accident. The scant evidence available on social media does suggest that this aircraft accident fits into the category of Loss of Control in Flight. However, that suggestion is purely informed conjecture at this time.

I agree with David Learmount[4] in that it’s likely that this will be found to be a preventable accident. That said, once the accident flight recorders have been replayed there should be a substantially better indication of what really happened on that fateful day.

Whereas it was previously reported the accident recoders were going to France it’s now reported that they are going to Singapotre for replay Black boxes from Nepal plane crash to be sent to Singapore – ABC News (go.com)

Based on the experience of the analysis of numerous accidents it’s unlikely to be a simple single cause. Such fatal aircraft accidents are often combinations of factors that come together. Approach to a new airport plus an unexpected event or error plus aspects of organisational culture can be enough to tip the balance.

Aviation, in itself, is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.

A quote of Captain A. G. Lamplugh, British Aviation Insurance Group, London. c. early 1930’s. This famous phrase has been reproduced on posters many times.

POST: Here’s some examples of what can happen again and again. Lessons learned from business aviation accidents maybe equally applicable to this case. Lessons Learned from Business Aviation Accidents | NBAA – National Business Aviation Association

Still learning leasons

Mobility has transformed society. By land, by sea or by air the world we see around us has been shaped by the technology that has enabled us to move people, goods, and services. Aviation, the youngest means of everyday transport, has radically transformed society in just over a century.

Demand for air transport is linked to economic development and at the same time air transport is a driver in an economy. Nearly all States work to encourage the growth of aviation in one form or another. All States acknowledge the need for the stringent regulation of activities in their airspace.

4.5 billion people moved around the globe by air. Well, that is until the COVID pandemic struck[1]. Even so, there’s an expectation that global air traffic levels will start to exceed those of 2019 when we start to get into 2025 and beyond.

One quote, among many, sums up the reason for the safety regulation of flying, and it is:

“Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.”

[Captain A. G. Lamplugh, British Aviation Insurance Group, London. 1930.]

Here the emphasis is on aviation safety and security as the top considerations. In fact, ask an airline CEO of the number one priority of their business and that’s likely how they will answer, if on the record. Much of that open expression will be sincere but additionally it’s linked to the need to maintain public confidence in the air transport system.

We need to remember that aviation had a shaky start. Those magnificent men, and women in their flying machines were adventurous spirits and born risk takers. That is calculated risk takers. Few of them lasted long unless they mastered both the skill and science of flying.

In the post war era, improvements in aviation safety have been dramatic. As the number of hours flown and the complexity of aircraft has grown so has the level of flight safety. Aviation has been an uncompromising learning machine. A partnership between States and industry.

Sadly, in part, the framework of international regulation we may now take for granted has been developed because of lessons learned from accidents and incidents, many of which were fatal.

AI2

There’s not just one form of Artificial Intelligence (AI). This group term hides a great panoply of different configurations, shapes, and forms of applications.

One of the most impactful applications is that of machine learning or expert systems. It’s where we go beyond a conventional computer’s ability to store and manipulate information against set rules. It’s where the machine has the capability to learn new ways of interpreting information and thus becomes different every day of operation from the day it was switched on. That’s a bit vague but it captures the essence of moving from deterministic to non-deterministic systems.

In all this we do presuppose that such complex systems are in the hands of able and highly illiterate users who understand what they are doing in training that learning machine. There’s debate about how bias in algorithms can produce unintended consequences. In addition, a reliable and trustworthy machine can be trained in a way that embeds errors and biases too[1].

Just as a child picks up the bad habits of a parent, so “intelligent” machines can learn from pilots, controllers and engineers who may have less than optimal ways of undertaking tasks. This Human-AI interplay is likely to become a major area of study. As the topic of Human Factors is itself a large body of material.

Already with the debate on social media it is all too obvious that the aviation community has a wide range of views on the use of AI. All the way from utter rejection, or scepticism deeming such systems as “unsafe” to advocates who profess only the benefits and merits of such systems.

Clearly, both extreme ends of the spectrum of professional views don’t help much. I don’t think that the promoters of AI want to see blind overreliance on it. Equally, surly even ardent sceptics can see virtue in making the best use of the accumulated knowledge that is available.

I can foresee a system of systems approach. With my parent and child analogy, from time to time a child will ask a question that is blunt and to the point. A question that demands a straightforward answer. This can be uncomfortable but hits out at biases and bad habits.

In aircraft systems there are boundaries that must be respected. The physics of flight dictate that going beyond those boundaries is generally not good for life and limb. So, a system programmed to question an expert system, one AI questioning another AI, or even question its trainer, is not beyond the realms of possibility. It might even be a good idea.

Artificial Intelligence

In an on-line event, I listened to Professor Dr. Saskia Nagel of Aachen University[1] speak on Artificial Intelligence (AI) and Ethics last evening. It’s a topic that arouses a lot of interest amongst engineers and just about every other profession.

The talk was a round robin of the subject touching on points of debate that are far from resolved. Her talk provided an overview of key present ethical questions spanning the development and uses of “AI” technologies. It’s interesting that even the title of the talk was questionable. The debate rages as to what is encompassed in the commonly used term “AI”.

Scientific and technological advances have consequences that are best anticipated, in so much as we can. Far too often, as in the case of mobile phones, a capability has been launched onto humanity because of its great utility without much thinking through of potential impacts.

In a way, our collective mindset remains stone age. We do things because we can rather than asking the question as to whether we should or not. The Australian movie and musical Muriel’s Wedding captures this nicely[2]. “You Can’t Stop Progress” was the election billboard slogan of politician Bill Heslop in the story. The same theme might be posted as “Growth, growth, growth” in the current economic climate.

To an extent that’s what’s happening in the more audacious parts of aviation innovation. Different ways in which AI technologies can be used to facilitate autonomous flight are being explored and promoted. There’s no doubt such technology can process massive amounts of information in no time at all when compared with you or me. That advantage is only one side of the story.

Investigating questions of autonomy quickly leads to discussions on accountability and responsibility. In flight, there’s inevitably complex interactions between people and machines. On the normally rare occasions when this results in harm it’s essential to be able to say what or who was responsible.

It goes further than that too. Even to persuade a passenger to ride on an autonomous vehicle a good deal of confidence must be built-up. A fear of flying is often counteracted by arguments based on the long history of safe flight and the trustworthiness of those operating a transport system.

A question is: how do we trust something we don’t understand? Not a new question. Few members of the flying public may understand how a modern transport aircraft works. We put our faith in independent knowledgeable professionals asking difficult questions of the designers and builders of aircraft. We put our faith in rigorous controls and processes. If the internal workings of a complex machine are not explainable to those independent professionals, we have a problem. Thus, another key topic of explainability.

This is a fascinating research area. I’ve no doubt there are workable solutions, but we are some ways from having them to hand at the moment. Applied ethics are part of the toolbox needed.

Poor law making

If you thought the Truss era was an aberration, and that the UK’s Conservative Party had learned a lesson, then please think again. Wheels set in motion by the ideologue Jacob Rees-Mogg MP are still spinning.

The Retained European Union Law (Revocation and Reform) Bill is trundling its way through the UK Parliament. The Government Bill will next be prepared for its 3rd reading in the House of Commons[1]. The Conservative Government has brought forward this Bill to revoke, reform or revise all the remaining law in the UK that was formerly derived from the UK’s membership of the EU. This turns on its head the normal approach to changing UK legislation. Revocation is automatic unless there’s an intervention by a Minister.

UK civil aviation depends on several thousand pages of legislation derived from EU law[2]. Much of this law was created with considerable contributions from the UK. There’s hardly any if any advocates for automatic revocation of current aviation legislation. Even the thought of this action sends a shiver down the spin of aviation professionals. Generations of them have worked to harmonise rules and regulations to ensure that this most international of industries works efficiently.

Unless amended, the Government’s EU Retained Law (Revocation and Reform) Bill[3] could turn out to be an absolute disaster. Even those who have an irrational wish to eliminate any and every past, present, or future link to Europe must come up with a practical alternative and do this in an incredibly short time. Without a consistent, stable, and effective framework civil aviation in the UK will grind to a halt. Again, even those who have an unsound need to change for change’s sake will be hitting a vital industry hard, as it is only just getting back on its feet after the COVID pandemic and now setting out to meet tough environmental standards.

It’s going to be interesting to see what happens when this poor Bill reaches the House of Lords. Once again, the country will be relying on the upper house to add some common sense to this draft law.  

POST 1: The 3rd reading debate makes it clear that the Government is unsure which laws are covered by the Bill. If the Ministers responsible for this legislation do not themselves know its extent, how can anyone expect civil servants working on this legislation to know the full extent of change?

Where’s the common sense?

It’s two whole years since the end of the UK’s Brexit transitional period. That’s since the day when the UK fully withdrew from the European Union (EU). Have we seen any, I mean any, Brexit benefits from the day of the Brexit referendum? The sad truth is – No. We are worse-off. Investments haven’t happened, political turmoil persists and bureaucratic barriers have grown.

Certainly, it’s right to say that British politicians have been busy. They have found lots of targets to blame for this continuing underperformance. You name it; Remainers, young people, environmentalists, protesters, strikers, human rights, overseas aid, COVID, flu, global economic downturn, energy prices, war in Europe, Biden’s administration, China, France, Germany, hot weather, cold weather, the list goes on and on and on. The Brexiter’s blame list is an exceptionally long one. Add to this the fact that Boris Johnson comes in for caustic blame. Often strongest from the people who trumpeted his ascendancy to power in 2019.

Although we should not dwell too much on the past, it’s as well to not let what has happened in this last year be swept under the carpet. Remember 2022, after 44 days, Conservative Liz Truss resigned as British Prime Minister (PM). She was the first choice of the members of the political party most entrenched in Brexit thinking. This extraordinary farce made the country look it was run by like a bunch of incompetent fools, of ill-disciplined fanatics, of preposterous comics.

The blatant dishonesty behind Brexit can not be denied. A recent example was the Government statement on having not attained a promised boost from new trade agreements. A ridiculous political line about not signing deals until they are right for the country is a brazen smoke screen to cover-up a significant lack of achievement[1].

We need some serious common sense injected into our politics. The UK is not going away. The EU is not going away. Both share an immense common interest. Both are faced with similar challenges and threats. Both share the same values.

Brexit has added to costs, adding to inflation, labour shortage and under performance. Most people[2] now accept this analysis and want to see serious change[3]. The more both Conservatives and the Labour Party cling on to the mythology of Brexit, the more damage will be done. Keir Starmer has confirmed that the Labour Party will not seek for Britain to re‑join the EU. What a reckless folly from a would be PM.
