Peaceful Border

It’s superfluous to say so. Canada is not the US, and the US is not Canada.

It quickly becomes clear. I’ve been fortunate to visit places east-west and north south. Although not the far snowbound North. The two countries do share geography. Rocky Mountains stretch across the North America. From British Columbia to New Mexico. The Great Plains span North America. A stark contrast to the mountains, as a huge expanse. In the East, the rolling landscape of the Appalachian Mountains runs from Newfoundland to Alabama.

It’s not the same with social and economic geography or history. A profound difference has been forged by Canada’s citizens over a couple of hundred years.

If we look back to the late 17th and early 18th centuries the new world was a hugely different place than it is now. Britain, France, Spain, and their allies were fighting over vast territories. European conflicts translated into competition and trade wars. Eventually, America colonialist brought about a revolution, so there would be no need for royalty, aristocracy, or an imposed church. Rejecting their British masters, even if they did keep their system of laws.

At the start of the 19th century, the US did invade Canada with a couple of conflicts. So, the idea that the US may wish to annex a part, or all of Canada is not entirely new. I’m going to have to read up on the Battle of Stoney Creek of 1813. It seems a namesake of mine played a pivotal role in preventing the US from taking Canada[1]. No relation – I’m (almost) sure. Irish heritage.

My assumption is that US President Trump is doing what he has done times before. Mark out an extreme position from which then to shape future negotiations. That’s not so mad as it might appear. It’s not nice when considering the cordial relationships that have characterised so much of the recent past. Kicking at the sides of an ally.

Stretching over thousands of kilometres (or miles if you prefer), the boarder between the US and Canada is one of the most peaceful in the world. To reignite conflicts of a couple of hundred years ago is not a wise option. I’m sure Canada could call upon a great deal of support if the worst-case scenario were to prevail.

Mutuality may not be fashionable. It needs to be made fashionable, again. The notion of a win-win scenario where both parties benefit, it’s real, it’s not mythical. Both US and Canada are sovereign. It’s best for the world that it stays that way.

Avoiding Contrails and Enhancing Operations

Here I’m expanding on my earlier words on aircraft Contrails.

Airspace is a busy place. It’s most busy over Europe and the US. Over the oceans there’s more room, although on certain routes, like the North Atlantic, there’s plenty of daily air traffic.

Those who manage the airspace are primarily concerned with ensuring that aircraft collisions do not occur. The impact of mid-air collisions is devastating. There’re few people in aviation who can forget the events of an evening in July 2002. Over Überlingen, Germany[1], 71 people lost their lives at a time when the sky was not busy at all.

Managing the use of airspace is more than collision avoidance. Flying is perpetually concerned with the weather. What’s it doing, how is it changing and is it a hazard? It’s not just the safety of flying that demands up-to-date meteorological information. Knowing about the winds can enable more efficient operations, and that’s less fuel use for a given route.

Large thunderstorms need to be avoided. Regions of the world (example: intertropical convergence zone) make this a dynamic challenge. Manoeuvres may be planned but flight crews must be ready to act based on the information they have, like weather radar.

Turbulence is another phenomenon to be avoided, if possible. This can occur in clear air. It can be difficult to detect. Which explains the unpleasant examples that hit the News now and then[2].

Back in 2010, aviation had a reminder that avoidance encompassed any hazardous airspace. That was when an unpronounceable volcano in Iceland was spewing out ash at high altitudes. Plumes of volcanic ash, if ingested into aircraft engines, can cause major difficulties.

I’ve written these words to emphasise that the avoidance of contrail formation cannot be done as a stand-along consideration. It becomes one factor in a whole mix of factors.

Avoidance of contrail formation is about considering the mechanism that cause them to form. Clearly, the warmer the air is the harder it is for a contrail to form. The more humidity there is in the air, the easier it is for a contrail to form. Outside Air Temperature (OAT) and atmospheric humidity vary at each altitude. That relationship interacts with the aircraft inflight, and the outcome may be different for each aircraft type.

At least one academic study[3] says that adjustments of aircraft altitude of around 2000 ft could have a useful effect on contrail formation. That’s good to know but let’s not forget that Reduced Vertical Separation Minima (RVSM) [4] means a vertical spacing of 1000 ft in busy airspace.

My take on this fascinating subject is that there both a tactical and operational approach that can be practically taken by aviation.

At the tactical level, airlines can factor contrail avoidance into flight planning. Creating an algorithm that will weigh all the relevant flight factors. Improved sources of accurate and timely meteorological data and predictions will be needed.

At the operational level, it’s down to the flight crews to take advantage of environmental conditions as the opportunity arises. Much as dealing with turbulence, that is when safety and operational rules permit. To change altitude when its beneficial, computational help is likely to be needed. Over the ocean, air-ground communications systems may need to be further improved. An altitude change that avoids contrail formation but increases fuel consumption would not be a sustainable solution.

These computational tasks may well be well suited to machine learning. A useful application of artificial intelligence. I can imagine a cockpit weather radar display with a new set of symbology that indicates a low probability contrail formation zone ahead.

[Back in the 1990s, I worked on RVSM when the ARINC organisation was creating international standards. Safely increasing traffic in the North Atlantic region. Additionally, I participated in the certification of Future Air Navigation System (FANS) 1/A for use over the ocean. FANS led to more efficient aircraft operation due to shorter flying times and decreased fuel burn.]

Understanding Contrails

Crisscrossing the sky, as I look up on a clear day, there are civil aircraft going about their business. People travelling across the Atlantic or coming back or on a day trip to Glasgow.

These shiny pinpoints of light in motion, set against a blue sky, are all the more visible because of the vapour trails they leave behind. Aircraft speed through the rarified atmosphere to leave a momentary trail as evidence of their presence.

Up with the aircraft in flight are natural clouds. Up at 30,000 feet there can be Cirrus clouds[1]. There might not be much air pressure at that altitude but there’s enough moisture to support cloud formation. The word “wispy” sums them up.

Aircraft create condensation trails that are known as contrails. How the English language likes to shorten. They are not mysterious or generate with evil intent in mind. It’s simple physics.

In my bathroom, with hot water gushing from the shower, moisture is the air. When that moist air meets a cold surface, like a window, condensation is sure to be seen. Airbourne it’s not so different. Hot emissions from powerful jet engines shooting out into a cold low-pressure environment and guess what?

Typically, contrails don’t last long. If there’s appreciable wind at high altitude, then they get dispersed quickly. Not only that but the icy temperatures up there soon return things to the status-quo. There are days, when the air is still, that the sky can become a crisscross of contrails where dispersion is more like a gentle merging.

The theory goes that the cumulative impact of lots of high-altitude flying is like the impact of additional cloud formation. It’s water vapour after all. It’s known, high altitude clouds can contribute to the greenhouse effect.

The point I’m getting to here is that lots of flying contributes to climate change. Primarily because of the burning of significant amounts of fossil fuel. As a secondary consideration there’s the issue of contrails across the globe.

This leads to the question – can their formation be avoided? Even, is there something useful to be gained in doing so. Trials and research are trying to establish the answer to these questions[2].

Initially, contrail avoidance sounds like it should be relatively easy to do. However, like so many good proposals it’s not so easy. Change needs to involve air traffic management, flight operations and international regulators.

First the atmospheric conditions need to be detected or predicted in a given location and then an avoidance needs to be planned and undertaken in coordination with everyone flying at high altitude at a given time. Lost of data to crunch.

It’s possible, in oceanic airspace, a dynamic aircraft system could perform this avoidance function. It would be an interesting design challenge for an avionics company to take up.

Relationship with the EU

Monday, Monday[1]. It’s a wonderful 60s song. Harmonies and mood are perfect. I wonder if the harmonies and mood will be perfect for the Prime Minister (PM) on Monday. Already the Sunday Press are setting the stage for Monday’s performance.

Reset, recalibration, reheat, rekindle, re-whatever. It’s a moment when relations between the UK and the European Union (EU) can make realistic progress[2]. In world full of uncertainty (could be a song in that one), for once the direction of travel is a constructive and positive.

I think the word “deal” is getting overplayed. Indications are that there’s no fundamental shift from Brexit meaning Brexit, as one former PM liked to say. In fact, the current PM is being highly cautious in the light of his Party’s reading of the latest opinion polls. For no sane reason I can think of, the swivel-eyed loons of the far-right are making hay.

It’s astonishing me how dim-witted the Conservative Party is in objecting to something when they don’t even know, for sure, what it is. Mind-blowing. And the rum cult of Reform Party doing the same with extra bile. What a load of prehistoric fruit loops.

Brexit supporters are spreading misinformation, again. Saying that UK has no influence. It’s true, the UK doesn’t have votes in the European Council or Parliament, but significant influence can be exercised on standards, and regulatory guidance, nevertheless. A better “deal” can bring much greater influence. Absolutely vital in the digital world, and for the UK, a country with a services-based economy.

Brexit has cost the UK dearly. The UK Treasury would have billions more in its coffers if the 2016 referendum had never taken place. The standard of living of every person in the UK is lower because of Brexit bungling. Ideally, that great mistake is an event to be written up for the history books and then forgotten.

On top of the above, uncharacteristic moves in the US, with Trump tariffs there’s nasty hit at the UK’s future prosperity. There couldn’t be a better time to repair relationships with the UK’s nearest neighbours. The countries with which we share most of our long history.

Even for those on the political right, practically, the EU is never going away, so until the day the UK rejoins the block, it’s wise to have the best possible relationship in all matters. Goods, services and people need to connect as a case of mutual benefit.

It’s time for hope. An optimistic tone should be set. A smile. Let’s hope we are singing Monday, Monday so good to me, Monday morning was all I hoped it would be. Naturally, that there be no crying, come Monday evening.

Sustainable Aviation: Innovations and Challenges

Gas guzzling continues to be one of aviation’s problems. Combustion remains that the heart of most aircraft power plants. Taking large amounts of fossil fuel. Squeezing energy out of every drop of gasoline. Gobbling up more day after day. Pushing out emissions.

As I look out across the garden, I see gliding effortlessly as the warm air rises, a Red Kite[1] gracefully circling. Wings outstretched they hardly move them as they climb. They’re a distinctive small bird of prey, easily spotted because of their forked tail. Now, that’s what I call efficient flying. Using all that nature provides and wasting little energy.

Human attempts at flying are a million miles behind these magnificent birds. There’s still so much to learn about aerial navigation. It’s a matter of control. The sensing of ambient conditions and the precision movements needed to ascend and dive at will.

The search is on for effective change. There’s no pretence that the way commercial aviation operates is unsustainable. It’s true that the gas guzzlers of the air guzzle less gas now than they ever have but the physical facts remain.

None of this is new. I’m about to send a book called “Towards Sustainable Aviation” to a charity shop. It’s not that there’s anything wrong with it. The book is full of pertinent analysis and observations. Trouble is that it’s dated 2003.

I’m led to ask – what’s changed in over 20-years? In answering my own question – quite a lot but not enough. Discourse has moved on from academic quarters to the political sphere. Aircraft have become more fuel efficient. Driven by economic imperatives as much as any concern for the climate. Research initiatives are generously funded to come up with answers. Solutions like hydrogen, electric propulsion, and SAF (sustainable aviation fuel) are slowly moving from theory to practice. A few prototypes are flying. Limited supplies of SAF are flowing.

Unmistakable that’s where the problem lies. For all the hype, policy and government funding the pathway to genuinely sustainable aviation disappears way off into the horizon. There are setbacks too. Gas guzzling is back in fashion. Certainly, in Trump’s America.

We could make a much more of the technology that’s currently available. Yes, there are costs involved. Change is not a free ride. That said, sticking with the status-quo isn’t free either. Legacy costs mount up. One reason why older jets disappeared from fleets so quickly.

The next generation of commercial aircraft must make major steps forward. Since the life of a typical aircraft type can easily extend to 30-years, then change must happen in design now.

Typically, commercial aviation moves with graduated change. There’s an inherent conservatism in the system, as might be expected when safety and security are paramount. Facing this global challenge, there’s a need for a degree more radicalism.

Since high impact disruption is also in fashion, it’s time for airlines and manufacturers to adopt a pioneering spirt. It’s been done before. In the 1960s, that pioneering spirt gave us the Boeing 747, the Jumbo jet. That opened flying to a whole generation.

Exploring a Riverside

Riverside walks can be pleasant ways of spending a sunny spring evening. That’s what I did on Friday. Sun shining with a cool breeze sweeping through the trees. Underfoot even the unmade-up paths were dry, which is testament to the rainless weather of recent weeks. Even so, the riverbank showed signs of the flooding of the winter.

Reading is a town[1]. It’s England’s largest town. Now, I didn’t know that until I looked it up. The largest English town that I’ve been familiar with over the years is Crawley in Sussex. I think of that as a large town but it’s less than half the size of Reading. It’s the railway that makes Reading. Reading railway station was the last stop on the Great Western Railway (GWR)[2] when it was first opened in 1840. After that the railway forged west to be what we know now as the main thoroughfare across southern England.

Reading town has a long history. That’s no surprise given its position on the river Thames. It’s where the river Kennet, the canal and the river Thames meet. An obvious place for trading since Roman times. It’s a commercial town. Glass sided office blocks and Victorian brick work. For all that it doesn’t stand out as an architectural masterpiece.

Another surprise for me was leaning that town twinning is alive and well. That Reading in twined with Düsseldorf in Germany. A city more than twice the size of Reading. In fact, until this last year, I’ve been more familiar with Düsseldorf.

Our walk ended at The Fishermans Cottage[3]. I’m happy to recommend this small riverside pub.

From there, on the walk back to the railway station I did see the one of the more notable sites in Reading. That’s the Banksy’s Great Escape artwork[4] on Reading prison wall. Oscar Wilde spent time in that jail. The artwork has got a Perspex cover to keep the pigeons off. And anyone else who might think of spraying it.

That reminds me. It’s not unusual to have a phobia about dogs. Although dog owners mostly have a difficulty in getting their heads around the fact. On my riverside walk dogs were not the problem. Amongst our small group of walkers had a different phobia.

As we got to the confluence of the Thames and the Kennet, we discovered the phobia of one of our walkers. Alfred Hitchcock would approve. The Kennet’s tow path attracts Swans. These Swans are attracted by people with food. With no inclination to get out of the gently flowing river these lazy Swans wait for passers-by to pay attention to their needs. That’s no problem.

It’s called Ornithophobia. A fear of birds. Birds flock when free food is on offer. The worst of these can be thought of as flying rats. I talk of pigeons. That how I think of pigeons. Tom Lehrer[5] had the right idea about these annoying birdies. Frightening them away, at least for a moment, cleared our pathway. Like a flash they returned as we strolled into the pub.

Europe Day Highlights the Need for Unity

Keeping the peace is never easy. There’s an irrational propensity to conflict in human nature. Keeping the peace is not a passive task. First, it requires communication and engagement. When those two go, trouble is not far behind. It’s by expressing concerns that each side knows where the other stands. Escalation can come when ignorance and propaganda take over.

After the second world war, institutions were established to ensure that communication and engagement became a non-stop affair. With only a small number of exceptions, the countries of the regions of the world engaged in these institutions. Those measure have contributed to making a more prosperous world.

“Never again” are two words that refer to the atrocities of war. The moto is to remind everyone that the worst can and does happen, and that perpetual effort is needed to ensure that history does not repeat itself. The concept of “lessons learned” is essential for safety and security. This is as much true for micro day to day activities as it is for the macro events that shape the path global ahead. Taking teaching not from narcissistic demigods and snake oil salesman but from the pages of history. Appeasing tyranny is not an option.

This week has been a reminder of the lessons learned from the world wars. For most people it’s been a continuing commitment to ensure such events never happen again in Europe. Sadly, let’s not be coy. Despite an overwhelming desire for peace, conflict in still Europe is a reality. But the lesson is there in black and white, appeasing tyranny never works.

Today, Friday 9th May is Europe Day. That’s because a speech by Robert Schuman[1] changed the course of European history on this day. Five years after the war in Europe had come to an end, he put forward a proposal that would make a future similar conflict impossible. The idea was to create an interdependence that would secure peace, unity and solidarity.

It worked. His proposal led to the creation of a European Coal and Steel Community. That measure lay solid foundation for what would later become the European Union (EU). Behind this is move is the echo of “Never again”. Europe has seen centuries of war. This was a moment in time to bring that to an end.

For now, 75-years on, this has been a success. It’s not a regional project with a defined end, even if it has a defined beginning. Where the EU chooses to go next is in the hands of its Member States and its citizens. Changing the course of European history doesn’t stop because the EU exists. Without the cooperation and dialogue, it provides there’s always a chance that ancient rivalries will be reignited. In fact, unscrupulous right-wing politicians[2] are trying to do that just now.

Sadly, in the UK, we stand on the sidelines, looking across the water at continental Europe. Brexit has done a great deal of damage. But as I have said, nothing is static, the world is entering an ever-uncertain phase. The opportunity for the UK to restore EU relations is open. I see the wisdom in the words of the Governor of the Bank of England. He has said the UK now needs to “rebuild” Britain’s relationship with the EU. Amen to that.

Cities Shaped by War

War is failure. Humans being quick to aggression, possessive and slow to reconciliation, it’s plagued every corner of history. Reason to go to war can be imperial, territorial, moral or ethical. In a democratic society, defeating an evil becomes an overwhelming imperative. That was certainly the case in the six years of the second world war. This week, it’s time to look back. To recollect the impact of the world war. To remember the sacrifice and suffering. To be thankful for the last 80-years years of relative peace in Europe.

For me these recollections take me to the experience of living in two cities. Cities on different sides of past conflicts. Severely damaged by the conflict. Targets because of their civic and industrial strength. Both cathedral cities with an ancient heritage.

My student life was spent in Coventry[1]. A decade of my working life was spent in Cologne[2].

Arriving as a fresh-faced student in the heart of the industrial Midlands, the architecture of Coventry city centre was so striking. It was that post-war vision of rebirth at a time when economic decline had set in. With an inner ring-road that was like a go-cart track, 50s style concrete avenues, windblown and neglected, there was little of the Medieval splendour of the pre-war city remaining. Standing proud in the middle of it was, and is, the skeleton of the old cathedral and the new one that ascended like a phoenix from the flames of war. Well worth a visit, the cathedral built in the 60s is a wonderful modern design. It plays with light and space to elevate emotions. A sign that we have a great capacity for reconciliation and regeneration.

Moving on just over 20-years, my encounter with Germany’s fourth largest city was full of hope and optimism. Based in Cologne, I experienced a city with even deeper roots than Coventry. Ironically, it was the destruction of the war that uncovered much of the Roman remains on display. At Cologne’s heart is a magnificent gothic cathedral that is more dominating of the landscape than perhaps ever it has been. Here the citizens of the city took a different approach to post-war rebuilding. Not so much embracing everything that was new, although there’s quite a bit of that approach, but reconstructing the old city in its original style. The culture of the city survives in the traditions of the annual carnival.

These two European cities have taken different paths. All the same, there are threads of common experience. Both have seen industrial decline and a search for a better future to thrive and grow. Both are distinctive and culturally colourful. Both carry the baggage of a brutalist architecture that was fashionable on the drawing boards of the late 1950s.

Visting the past in museums and walking the streets the marks of the last war are there to be seen by everyone. Passed by every day. Yet, mostly ignored in the humdrum of commuting and the busy obsession we have of staring at a “mobile” or call it a “handy”. Now and then it’s as well to look up. To look and see the bullet marks on stone structures, the nicely arranged medieval or Roman stones and cobbles, or the conserved streets that contain the ghosts of past generations. For good or ill, war has shaped the world we inhabit.

Peace is a far far better condition. I think of the “Coventry Cross of Nails[3]” as a symbol of reconciliation and peace. Let’s not forget.

Travel’s Societal Impact

Privilege is all around us. It’s, by definition, not equality. It’s a privilege to live in a country not torn by war or where the environment has not been decimated. It’s a privilege to be able to protest and strongly disagree with the powers that be. Indeed, in this country it’s a right too.

Debates about the moral or ethical grounds of inequality will never cease. That’s a hope of mine. For the minute we become timid and cowed by an authority that would rather supress such debates, then that’s the end of our democracy. We’d be free no more.

A large part of my career has been in the aviation industry, in one way or another. Putting aside the military uses of aviation, that’s another debate, civil aviation and the travel industry are two peas in a pod. Flying facilitates travel. Largely international travel. Apologies to the cargo industry, leisure flying and so many others.

One phenomenon that is not new, is that of raising the issue of responsibility. For example, the consequences of tourism to natural environments are often negative. Not always so. Huge effort is made by some countries and organisations to make tourism a positive. However, generally there are significant challenges to be grappled with in making travel affordable for all.

Wealthy young Europeans have been roving across boarders as part of a rite of passage since the 1600s. A “Grand Tour” was a form of discovery, education and cultural enrichment. Today, a student might call that a gap-year. Time taken out of formal studies to travel abroad. The aim, as well as having fun, is to return a more rounded person ready for whatever life might throw up.

Where do we sit as a society in terms of the balance between personal freedom and our collective responsibilities? Are activists right to attempt to slam or shame travellers for the negative impacts that they can trigger? These are uncomfortable questions. Ironically, these difficult questions are often raised by the people who have enjoyed the privilege of travel.

In my mind, a debate on this subject of balance reflects greater societal issues. When we look at a basic hierarchy of human needs then international leisure travel may not be top priority. However, life would be less rich and colourful without it. Embarking on an epic journey, that takes a traveller outside their comfort zone, can be a life changing event.

To defend the freedom to travel, I cannot avoid looking at the other side of the equation. There is an overwhelming responsibility to do something restorative. Ignoring the impact of travel, particularly civil aviation, is not an option anymore.

I know there are some politicians who scream for the abandonment of Net Zero policies and all they entail, but they are extremely foolish. Shifting the burden onto future generations is reckless. Appealing to those who want to escape the debate, or force a return to mythical age, is nothing more than doomed short-termism.

This is one reason I’m an advocate for electrification and the exportation of radical solutions, like hydrogen powered civil aviation. Technological solutions are part of the path to take. That, in of itself, may not be enough but at least engineering change is permanent.

Solutions by design are far more powerful than ephemeral political posturing. Legislation can be overturned in a weekend. A whole new way of operating aviation can be sustained for decades.

Communication Prevents Disasters

It’s often forgotten that there’s a need to repeat messages. We are not creatures that retain everything we see and hear. There are exceptional people, it’s true, those who cram away facts and have an amazing level of recall. Often that’s my reaction to watching students leading teams on University Challenge[1]. How on earth do they know those obscure facts?

Most of us do not respond well to those who say, “Well, I told them once. I’m not going to tell them again.” That line is probably one of the most misguided utterances a teacher can make. Like it or not, this approach is part of our heritage. Past ages, when deference was expected, listening was mandatory, and misremembering was entirely the listener’s fault.

We’ve had a cultural shift. Our complex technological society doesn’t work in a command-and-control way. Too many disasters can be traced to miscommunications and misunderstanding. Now, the obligation exists on those delivering a message to go some way to ensure that it’s received with a degree of comprehension. That’s when repetition has a role to play.

One of the pillars of Safety Management Systems (SMS) is Safety Promotion. It’s the Cinderella of the aviation safety world.

Why do I say that? Experience for one. It’s much easier to get policy made and funding for the “hard” sciences like data acquisition, analysis and decision-making systems. These are often perceived as providing tangible results. Actionable recommendations that satisfy the need to be recognised as doing something. Even if that something is questionable.

Communication is key to averting disasters. It’s no good having pertinent information and failing to do anything with it, other than file it. The need to know is not a narrow one. Confined to a specialist few.

Let’s go back to 2003 and the Space Shuttle Columbia accident[2]. This craft was destroyed in a disaster that claimed the lives of its crew. The resulting investigation report is extremely compressive, if slightly overwhelming, but it has some key points to make.

To quote, “That silence was not merely a failure of safety, but a failure of the entire organization.” [Page 192]. In other words, the hidden concerns and internal machinations of an organisation can smother safety messages and led to failure. Since 2003, it’s sad to say that there are multiple occasions when what has been learned has been ignored. The impact has been devastating.

So, to shape the future let’s remember the Cinderella of the aviation safety. Discovering problems is not enough. It’s vital that practical solutions and good practice gets promoted. That needs to be done forcefully and repetitiously.
