Comms

The long history of data communications between air and ground has had numerous stops and starts. It’s not new to use digital communications while flying around the globe. That said, it has not been cheap, and traditional systems have evolved only slowly. If we think Controller Pilot Data Link Communications (CPDLC)[1] is quite whizzy. It’s not. It belongs to a Windows 95 generation. Clunky messages and limited applications.

The sluggishness of adoption of digital communications in commercial aviation has been for several reasons. For one, standardised, certified, and maintainable systems and equipment have been expensive. It’s not just the purchase and installation but the connection charges that mount-up.

Unsurprisingly, aircraft operators have moved cautiously unless they can identify an income stream to be developed from airborne communication. That’s one reason why the passengers accessing the internet from their seats can have better connections than the two-crew in the cockpit.

Larger nations’ military flyers don’t have a problem spending money on airborne networking. For them it’s an integral part of being able to operate effectively. In the civil world, each part of the aviation system must make an economic contribution or be essential to safety to make the cut.

The regulatory material applicable to Airborne Communications, Navigation and Surveillance (CS-ACNS)[2] can be found in publications coming from the aviation authorities. This material has the purpose of ensuring a high level of safety and aircraft interoperability. Much of this generally applicable material has evolved slowly over the last 30-years.

Now, it’s good to ask – is this collection of legacy aviation system going to be changed by the new technologies that are rapidly coming on-stream this year? Or are the current mandatory equipage requirements likely to stay the same but be greatly enhanced by cheaper, faster, and lower latency digital connections?

This year, Starlink[3] is offering high-speed, in-flight internet connections with global connectivity. This company is not the only one developing Low Earth Orbit (LEO)[4] satellite communications. There are technical questions to be asked in respect of safety, performance, and interoperability but it’s a good bet that these new services will very capable and what’s more, not so expensive[5].

It’s time for airborne communications to step into the internet age.

NOTE: The author was a part of the EUROCAE/RTCA Special Committee 169 that created Minimum Operational Performance Standards for ATC Two-Way Data Link Communications back in the 1990s.

Just H

What is the future of Hydrogen in Aviation? Good question. Every futurologist has a place for Hydrogen (H) in their predictions. However, the range of optimistic projections is almost matched by the number of pessimistic ones.

There’s no doubt that aircraft propulsion generated using H as a fuel can be done. There’s a variety of way of doing it but, the fact is, that it can be done. What’s less clear is a whole mass of factors related to economics, safety and security and desirability of having a hydrogen-based society.

H can be a clean form of energy[1], as in its purest form the process of combustion produces only water. We need to note that combustion processes are rarely completely pure.

It’s an abundant element but it prefers to be in company of other elements. Afterall, the planet is awash with H2O. When H is on its own it has no colour, odour, or taste. In low concentrations, we humans could be oblivious to it even though there’s a lot of it in the compounds that make us up.

Number one on the periodic table, it’s a tiny lightweight element that can find all sorts of ways of migrating from A to B. Ironically, that makes it an expensive element to move around in commercially useable quantities. H is often produced far away from where it’s used. For users like aviation, this makes the subject of distribution a fundamental one.

Part of the challenge of moving H around is finding ways of increasing its energy density. So, making it liquid or pumping it as a high-pressure gas are the most economic ways of using it. If this is to be done with a high level of safety and security, then this is not going to come cheap.

There are a lot of pictures of what happens when this goes wrong.  Looking back at the airships of the past there are numerous catastrophic events to reference. More relevantly, there’s the space industry to look at for spectacular failures[2]. A flammable hydrogen–air mixture doesn’t take much to set it off[3]. The upside is that H doesn’t hang around. Compared to other fuels H is likely to disperse quickly. It will not pool on the ground like Kerosene does.

In aviation super strict control procedure and maintenance requirements will certainly be needed. Every joint and connectors will need scrupulous attention. Every physical space where gas can accumulate will need a detection system and/or a fail proof vent.

This is a big new challenge to aircraft airworthiness. The trick is to learn from other industries.

NOTE: The picture. At 13:45 on 1 December 1783, Professor Jacques Charles and the Robert brothers launched a manned balloon in Paris. First manned hydrogen balloon flight was 240 years ago.

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.

Every little helps

When drawing comparisons with parts of the UK, it’s responsible to say that the town I live in, Reigate[1] in Surrey is relatively affluent. However, much debt people may be carrying, the amount purchasers are prepared to pay for houses in this town is way above the national average.

Past associations between affluence and the habit of voting Conservative in local and national elections is well established. That said, for a good half of the population in Reigate there’s no love of what the Conservatives have done over the last 12 years. In fact, I would wager that a good number of former Conservative supporters are well and truly fed-up with the never-ending deception and incompetence of that political party.

Yesterday morning, just for a short while, in the chilly air a few local people gathered on a street corner to protest. Their concerns included polluted rivers, climate crisis, cost of living crisis, real incomes falling, idiotic Government rhetoric, corrupt politics, a damaging Brexit, and the suppression of the right to protest. The public response was overwhelmingly positive. Drivers tooted their horns in support, people waved and stopped to chat.

As is perfectly reasonable, there were a small number of passers-by who disagreed with the group’s banners and posters. Most often this was a shaking of the head or a traditional English gesticulation, but in addition one or two words were voiced. That’s the heart of the matter. It mystifies me how some people can be happy with the current predicament in Britain.

The most distressing words uttered were: “What’s the choice?”

There are several ways to interpret this negative shout-out. One: it could be a cry of genuine desperation.  Two: it could be a deep reticence accepting a bad situation and a loss of hope. Three: it could be a stubborn Conservative who’d be happy regardless of the situation.

This is what those who want to see change happen have got to get to grips with this year. To bring real change about there needs to be a big collection of people who openly welcome change. That does mean embracing those who are still sitting on the fence.

It means seriously building confidence that today’s troubles can be beaten. As can be seen from this small group’s posters the list of troubles is long, so this is no simple task. Hope for the future means overturning incompetent incumbents and giving a chance to competent fresh faces. It means having honest and practical solutions ready to go. It means having a vision. 

Rebuilding Britain’s liberal democracy is the vital and urgent mission.

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.

Over the Horizon

How often does the obvious comment need to be made? It’s Sunday 11th February and the new UK Secretary of State for Science, Innovation and Technology has only been in the job for a few days.

UK Ministers Michelle Donelan latest utterance is straight out of the failed Brexit playbook. The UK is “ready to go it alone”, she says[1]. Let’s puff up our chests, money is no object, the UK doesn’t need to be part of the €95.5 billion Horizon Europe[2] programme of the EU. Or at least that’s what she and her colleagues seem to be saying.

The rather silly argument is made that the UK will work with the US, Switzerland, and Japan instead. Now, hang about, call me a bit crazy but couldn’t the UK do both?

There’s no way the UK can become a global science powerhouse without working with both the EU and the rest of the world. Well, with a few possible exceptions. Afterall, it would not be wise to be forging research links with Russia at the moment.

Partnerships and collaborations matter so much because so many great ideas are based on the work done by others.

Already the UK is seeing a decline in research students coming from Europe and China. The Home Secretary’s struggles to control migration with all the subtlety of a sledgehammer doesn’t help.

Yes, the UK has a history as an inventor and can be capable in science even if we pull up all the drawbridges but that’s incredibly limiting, commercially crazy and like throwing a damp blanket over future pioneers. Remember young talent is mobile.

I do remember the exit of UK talent that occurred in my student days (1979-82). I’d meet some of them later in my career working in aerospace companies all over the world.

Putting aside all the above, big money matters, but what matters more is opportunity.  That is fertile ground for innovation.

Contrary to UK Government Minister’s thinking this has nothing to do with de-regulation either.

Across the Atlantic we have a highly regulated country that still seems to be able to produce innovators that go on to change the world. There are more lawyers per square mile in the US than just about anywhere on Earth but that doesn’t stop that country being an incubator for ground-breaking innovation. [Says me, on my Windows PC with my iPhone charging next to my iPad.]

Today, the US Inflation Reduction Act (IRA) is going to make funding available on a gigantic scale. The UK’s cash-strapped Government can’t match this US effort even if it wanted to do so.

Europe needs to work together. The UK needs to be one of the associated countries[3] to participate in Horizon Europe. The alternative is grim.

Truss

Stating the obvious about former Prime Minister Truss, and an attempt at a political makeover[1] does merit effort. There are some people unwise enough to wish to cover up a colossal failure. The facts are clear. Absurdly irresponsible economic and political policies plunged the UK into a crisis. The corrective action taken to recover from that situation cost the UK greatly both in monetary and reputational terms.

The approach taken by the right-leaning Conservative Truss cohort destroyed growth rather than drove growth. The people who announced last year’s mini budget are not “blameless.”

Let’s acknowledge that there will aways be some reckless believers in the approach taken at the launch of the Truss premiership. It’s better that they be heard. It’s better that their foolishness is exposed before it can be acted upon. It’s better that they remain a minority.  

Britain’s shortest-serving Prime Minister can be used as a textbook example of how not to govern.

There’s a search going on to address long-standing economic issues. It requires cool heads and clam reflection. Diatribes rent with dogma are useless and dangerous. Borrowing huge amounts to cut taxes is the sort of act that would have Margret Thatcher turning in her grave[2].

Reputationally the Conservative Party is in the sink. Their party chairman is out. Their deputy PM is hanging on by a thread. Members of Parliament are agitated and flailing around. It’s like the last days of John Major’s premiership.

It must be said that much British economic and political pain could have been avoided. I objected strongly to Brexit. It happened but it did not need to have happened in such a way as to create a massive downside. The loss of trade and good relations with our nearest neighbours has set the country back decades. It’s like we dug a big hole and willingly jumped into it. Our neighbours looked on mystified as to why we choose to jump into such a deep dark hole.

The one thing this current incarnation of the Conservative Party is good at is shooting itself in the foot and taking us all to a place where we don’t want to go.

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.

3-years on

Today, the weakest arguments are being used to sustain Brexit. Still the advocates of Brexit call for deregulation, slashing taxes but more Government borrowing. The Truss formula, despite its disastrous effect remains popular amongst Brexit supporters.

Britain, having left the EU Customs Union and Single Market, has agreed roll-over trade deals with some countries. However, there has been no huge boost to trade as Brexit advocates claimed there would be after the 2016 vote. Brexit negotiations drag on and on. It’s perpetual motion. Maybe there’s a fix to the Northern Ireland difficulties. Maybe not.

If you are inclined, you can always blame everything on the Government’s pandemic response. As politicians are apt to do, there are quite a few avenues open to excuse away the negative impact of Brexit.

The lies told during the UK referendum campaign of 2016 will not go away.

On the 3-year anniversary of leaving the EU, pollsters have been out and about to gauge public opinion. It seems that apart from some parliamentary constituencies in Lincolnshire, others show a majority think Brexit wasn’t a good idea. 54% say Britain was wrong to leave the EU[1][2].

We don’t not know exactly when the next UK General Election will be, but political parties are gearing up for the fight to come. Because of the dreadful First Past the Post (FPTP) electoral system the UK’s opposition parties have a hill to climb in the race for Westminster. Again, referencing the current polls, even with that hill to climb there’s a high likelihood that change is on the way.

The end of this Brexit Government will not come soon enough. Look at the state the country is in. The longer this Conservative party remains in power the more damage will be done.

NOTE: The United Kingdom withdrew from the European Union on 31 January 2020. Based on the Withdrawal Agreement that had been ratified by both the EU and the UK, a transitional period during which EU law continued to apply in the United Kingdom ended on 31 December 2020.

POST: Ardent Brexit supporters are saying: we have to give it more time. Judging our economic position after 3-years isn’t enough to draw conclusions. This is like saying that having made a bad investment, it’s best to stick with the bad investment. Some people may agree with this type of argument. I say it’s foolish. The Brexit referendum has done damage. It will only be repaired by reversing a destructive and much regretted decision.
