Electrics & Mechanics

Yesterday, I wrote on LH2. The potential fuel for electric aircraft of any size. Yes, I’m not just talking about smaller commuter class transport aircraft.

Let me take some anecdotal evidence from the transition that is going on in road transport. Repairer turns up to fix an electric car that will not start. It’s a simple matter given that the car has been standing unused for a long time. The battery had discharged. A quick charge from another battery pack and all is well. Meantime in conversation it’s clear that the repairer hates working on electric cars. I could say, no surprise, they were trained on combustion engines and have been forced to make a transition in technology.

What’s evident here is the apprehension of a person who likely has a mechanical bias towards their work and the necessity to take on fixing powerful electrics. Mechanics, those who love working with moving parts, often have a dislike of electrics and electronics. It’s an engineer’s “feeling” expressed to me casually over the last 40-years.

In fact, it can be the reason that a design or maintenance engineer took the career path that they did. There is a dividing line between mechanical engineers and electrical engineers that is embedded in our institutional, educational, and training systems.

So, there’s two practical human issues to grapple with in a transition:

  1. Propensity of one branch of technically capable people to find mechanical work less fearsome and more satisfying than electrics or electronics, and
  2. Streaming that is embedded in our institutional, educational, and training systems. Qualifications and recognition are often not so multi-disciplinary focused.

I’m not for one single moment making a luddite argument that mechanical engineers[1] and electrical engineers[2] are two tribes that must be kept apart. Far from it. What’s more important is to recognise that transitions are hard.

New electric aircraft are going to demand technical people with a multiplicity of both mechanical and electrical knowledge. The way the engineering world has been divided up in the past doesn’t cut it. Some of our most cherished niches will need to be challenged.

Transitions of this nature always take much longer than is originally anticipated. In a way, that should be such a surprise. It’s a generational change for a community that can be conservative with a small “c”.

This is NOT business as usual. For example, handling powerful 1000-volt electric technology is not for everyone. Removing and replacing cryogenic plumbing is, again, not for everyone. The hazards are clear. The skills needed are clear.

Reorienting the aircraft maintenance engineering world is going to need new plans and programmes. Better start by enthusing people about the change rather than just forcing it.

Culture

Yet again, Boeing is in the news. The events of recent times, I feel are immensely sad. Now, it is reported that the FAA has opened an investigation into a possible manufacturing quality lapse on the Boeing 787 aircraft[1]. Concern is that inspection records may have been falsified.

A company that once had a massive professional engineering reputation has sunk to a place where expectations are low. It’s not so much that the company is having a Gerald Ratner moment. Unfortunately, the constant stream of bad news indicates something deeper.

It’s interesting to note that Frank Shrontz[2] passed away last Friday at the grand age of 92. He was the CEO and Chairman of Boeing, who led the company during development of the Boeing 737NG and Boeing 777 aircraft. In the 1990s, I worked on both large aircraft types.

A commonly held view is that, after his time and the merger with McDonnell Douglas the culture of the organisation changed. There’s a view that business schools graduates took over and the mighty engineering ethos that Boeing was known for then went into decline. Some of this maybe anecdotal. Afterall, the whole world has changed in the last 30-years. However, it’s undoubtably true that a lot of people lament the passing of an engineering culture that aimed to be the best.

A famous quote comes to mind: “Culture eats strategy for breakfast.” Those sharp 5 words get discussed time and time again. Having been involved in a lot of strategic planning in my time it’s not nice to read. How wonderful intent, and well described policies can be diluted or ignored is often an indicator of decline. It’s that cartoon of two cavemen pushing a cart with a square wheel. One says to the other: “I’ve been so busy. Working my socks off”. Ignored, on the ground is an unused round wheel. If an organisation’s culture is aggressively centred on short-term gain, then many of the opportunities to fix stuff gets blown out of the window.

We keep talking about “performance” as if it’s a magic pill. Performance based rules, performance-based oversight, and a long list of performance indicators. That, in of itself is not a bad thing. Let’s face it we all want to get better at something. The problem lies with performance only being tagged to commercial performance. Or where commercial performance trumps every other value an engineering company affirms.

To make it clear that all the above is not just a one company problem, it’s useful to look at what confidential reporting schemes have to say. UK CHIRP is a long standing one. Many recent CHIRP reports cite management as a predominant issue[3]. Leadership skills are an issue.

Safety Culture 2

This may sound at variance with my last blog. I hope it’s not. I hope it’s complementary. What I’m highlighting here has been observed over decades of contact with a wide variety of organisations.

The term safety culture is fused into the pillars of ICAO Annex 19. The essence of building a good safety culture that fosters sound practices and encourages communications, in a non-punitive environment is at the heart of standards and recommended practices. With all those decades behind us the reader might assume that there’s unambiguous and well aligned attitudes and ways of working throughout the aviation industry. That’s not so.

On a spectrum of what could be called hard to soft the manner of application of know best practices can take different forms. By the way, please disassociate those two words with both easy and difficult. That’s not what I mean.

In my interpretation “hard” means like pages of Niccolo Machiavelli’s The Prince[1]. Aggressive, persistent, mandatory, uncompromising and all encompassing.

In my interpretation “soft” means like pages of The Little Book of Calm by Paul Wilson[2]. Harmonious, enlightened, progressive, sympathetic, and understanding.

As with extremes on any scale, going to the ends of that scale are not the best way to operate. I say “best” in terms of getting to ways of working to endure with engagement and effectiveness. I observe much of this depends on how power is disseminated through an organisational structure. Highly hierarchical organisations will approach culture differently from organisations with a relatively flat management system.

It may not be surprising to suggest that aviation Authorities can veer towards the “hard” approach and staff Unions towards the “soft” approach. Even when both are trying to reach the same goal. Where people come from a military background, command and control can be an instinctive reaction. Where people come from an advanced technology company background, collaboration and communication can be an instinctive reaction. In my observation there are advantages in both a hard and soft safety cultural approaches.

One advantage of a hard safety culture is that the time between discovery of a safety problem, taking corrective action and resolving that operational problem can be short. Clearly, that has distinct safety advantages. Certain airlines come to mind.

One advantage of a soft safety culture is that there can be the discovery of safety problems that would otherwise remain hidden. Where collective ownership of the problem is not in question. Again, clearly, that has distinct safety advantages too. Certain manufacturers come to mind.

I guess my message is as per much ancient thinking. All things in moderation. Try to reap the benefits of both ends of the scale. Balance.

Flying a kite

Political discussion is much as it often is. One side is an abomination the other is the only way. Reverse that theme and you can sing the song of either Conservative or Labour party. Test yourself and see if you can think of a positive, constructive, cross-party initiative that is making Britian a better place to live. And that it isn’t jam tomorrow.

We are in a particularly febrile season. Holding the front page is mostly for atrocities, resignations, scandals and promises broken. Future quizzes about early 2024 may feature the question – who was Prime Minister or why was the inevitable General Election delayed?

I stripped off the daily one-page calendar for the 15th and the saying presented was – Imagination is the highest kite you can fly. There is a sentence to end the week. In the face of grinding pragmatic reality and the predictability of the worn out adversarial political order what if there was some imagination?

Much daily News concerns conflict, war, crime, funding cuts, inflated claims, and disagreeable personalities. No wonder people are turning off serious News media. A diet of current events remains important in a healthy democracy. Sadly, lots of people are driven to News avoidance[1].

My recommendation is let’s have some daily News that stimulates the imagination. There’s a little tickle through on occasions. Sadly, again this is seen as a minority interest. The need for hope built on a positive vision for the future is great. The more people disengage with dependable, independent, and objective News, the more the spinners of misinformation and lies get a grip.

What is missing is imagination. It’s not so alien. To think we once had a prime-time show called – Tomorrows World[2]. It wasn’t a humours chat on a comfy sofa at teatime. Meandering about the lives of minor celebrities and entertainment plugs for coming shows.

For decades, the likes of Raymond Baxter, James Burke and Judith Hann took us on a weekly adventure. On reflection there’s an immense range in their presentations. From what now seems comical to what has turned out to be profoundly significant.

I propose a next generation version of Tomorrow’s World. It’s the Spirt of Imagination. Each week there would be an accessible, peak time, magazine style show that looks at what’s lighting up the world of science, technology, and engineering.

I’m not asking for a worthy educational STEM[3] fest. No. A show must be engaging. Not a bore fest. It must be led by talented communicators who have a passion and instinct for what people are talking about. It must look a generation ahead. Simultaneously ask grandparents to rediscover wonder.

Next Decade Aviation

Here, I thought I’d speculate on what’s coming our way. That’s looking at the next ten-years.

Although this maybe contradictory to my earlier writings the subject is by no means all or nothing. Aviation is a technology-based means of mobility. Without the technology component there is no flight. Aviation a youthful industry when compared with ships, roads, and rail.

On the other hand, people are at the heart of the aviation system. That’s particularly true in assuring its stability, safety, and security. People create, innovate and fix systems when they fail. People make go-no go decisions. People protect systems from attack.

Commercial aviation maybe a youthful industry but it has an inbuilt conservatism. It’s the characteristic of not wishing to change when systems are working well. This has both and upside and downside.

A maturity of rules, regulations, processes, and procedures comes about by continuous improvement. By people learning. However, it’s often the case that industry does not reflect the society that it serves. People are excluded or walk away when expectations are dashed.

Across the globe, the future of the aviation workforce depends upon change. There again is a rub. People operating in a successful system rarely welcome change. Especially, if the drivers for that change come from outside the tight knit community of aviation professionals.

The first decades of the jet-age were characterised by a sense of adventure, glamour, and pride. As commercial aviation became available to a wider traveling public there was a gradual opening to professional entrants from most sections of society, even if that was predominantly male.

Now, big company traditional career paths are more an exception rather than the norm. Aviation competes with other industries at a time of rapid digital transformation. This has the impact of opening a wide range of options to potential professional entrants. In the coming decade the trend is going to advance.

A successful aviation industry organisation looks for skills and behaviours as much as it looks for raw technical talent. Assuring stability, safety, and security means having a responsible attitude, an instinct to challenge and question.

Today in the post-pandemic world, the industry is going through a period some people have called the “great resignation”. A generation have walked away from the pressure and stresses of the crisis. Industry behaviour, in a rush to cut costs, exasperated this by treating people exceptionally poorly.

For a sustainable future, commercial aviation needs to work to eliminate the hire and fire cycle. The global aviation industry needs to think and act differently. Aviation needs to get off the trap of the “similar-to-me” effect found in hiring. When a selection bias dominates potential professional entrants are put off. Talented young people are likely to choose meritocratic employment where rewards are there for achievement and commitment regardless of non-relevant factors.

Some work will be replaced by automation. However, retaining aviation people with people skills, regardless of background, will be invaluable in the next decade.

Two upfront

One of the fundamentals that remains a part of civil aviation is having two pilots in the cockpit. It’s an indication of the safety related activities of the crew of a civil aircraft. Today, we have a mixture of human control and management. Pilots still fly hands-on when the need arises. The expectation is that throughout their working lives pilots have the competence to do so, at any stage in a flight.

Progressively, since the establishment of aviation’s international order in the 1940s the required crewing of aircraft has changed. Back in September, I visited the de Havilland Aircraft Museum in Hertfordshire. There I walked through the fuselage of a de Havilland DH106 Comet[1]. This was the first turbojet-powered airliner to go into service and it changed the experience of flying forever and a day.

That passenger aircraft, like aircraft of the time, had four crew stations in the cockpit. Two pilots, a navigator and flight engineer. It was the era when electronics consisted of valves in large radio sets and such long since forgotten devices as magnetic amplifiers. The story from the 1940s of IBM saying, “I think there is a world market for maybe five computers” is often repeated.

For modern airliners the navigator and flight engineer have gone. Their functions have not gone. It’s that having a crew member dedicated to the tasks they performed is no longer required. As the world of vacuum-tube electronics gave way to transistors and then to integrated circuits so computing got more powerful, cheaper, and abundant.

With a few significant failures along the way, commercial flying got safer and safer. The wave of change in a human lifetime has affected every mode of transport. More people travel to more places, more safely than ever could have been imagined 80-years ago. Does that mean the path ahead will take a similar shape? Excitable futurologists may paint a colourful picture based on this history.

Let’s get away from the attractive notion of straight lines on graph paper. That idea that progress is assumed to be linear. Tomorrow will be progressively “better” by an incremental advance. That’s not happening now. What we have is differential advances. Some big and some small. 

The aviation safety curve is almost flat. The air traffic curve, with a big hole made by COVID, is climbing again. The technology curve is rapidly accelerating. The environmental impact curve is troubling. The air passenger experience curve may even be at a turning point.

Touchscreen tablets already help flight preparation and management[2]. Flight plan changes can be uploaded and changed with a button press[3]. The squeezing of massive computing power into small spaces is being taken for granted. What does this leave a crew to do?

Back to the start. Two pilots in the cockpit, with executive responsibilities, remains the model that maintains public confidence in civil aviation. The golden rules still apply. Fly, navigate and communicate in that order. Crews, however much technology surrounds them, still need to act when things do not go as expected. Does this mean two cockpit crew forever? I don’t know.

Flight Ahead

Although, I’m an advocate of having people in control of machines it isn’t people that are opening new opportunities in transport. Technology is racing ahead and making the past illustrations of popular science magazines become a reality. I can do without the hype in the headlines of flying cars. Building expectations of one in every garage remains a 1950s dream or nightmare, dependent upon your point of view. Aside from that hot air viable new electric vehicles are in the works.

Heavier-than-air machine that do more than buzz around our heads are going to proliferate. The inevitability of this is open to question but if I was to assign a probability to it, the number would be close to one. If we stretch our minds back to an unobserved small corner of the planet in late 1903, a couple of diligent brothers flew a machine that hopped a short distance into the air under its own power. Many newspapers of the time didn’t bother to print this breakthrough story because wise and eminent scientists had told them that it was impossible for people to fly.

It’s clear, getting into the prediction business should be done with humility.

We have a dilemma. It’s so rare of us to turn away from advancing technology when we know it can be made. It’s even more irresistible when the economics scream out buy me. So, a ticket to ride in the realm of Urban Air Mobility (UAM) will need to be no more than a typical taxi ride. Given that a taxi ride from my home to Gatwick Airport is about £20 then that’s the mark to hit. True that short journey may not be commonplace by air at that price until around 2033, a decade away, but it will be irresistible when it comes.

This chapter in air transport, that is being written is as significant as that in late 1903. I know that’s a mega statement, but the signs do point that way.

Eventually, UAM will become a network of piloted and autonomous electric air vehicles operating between cities and major destinations like airports.

Now, a couple of solvable challenges stand in the way. One is the endurance and portability of the energy storage devices. The other is complexity and mastering the science and art of functional safety. There’s plenty of confident hyperbole to suggest that these two are short-term barriers to progress. I say they are not.

Weight is one of aviation’s biggest enemies particularly on small vehicles. Batteries are expensive, heavy and require tailored control. Autonomy or the semi autonomy, needed to make the economics click is challenging systems engineering orthodoxy. Both tasks require the meticulous diligence of the Wright brothers to get past. No fanfare or flashy investor can push them aside.

Making the absolute most of energy storage technology is essential. Finding the optimal configuration of batteries, transmission and control electrics means iteration and the tolerance of a good handful of failures. The engineering of what’s becoming a system of systems, with the complexity of vehicles and the complexity of traffic management, interacting at great speed demands extensive analysis and testing.

These tasks can be accomplished. Rushing them would be foolish. That’s difficult to resist when everyone wants to be first.

Duck

I take for granted that everyone knows the saying: “Red Sky at night Shepherd’s delight. Red Sky at morning Shepherd’s warning”. It’s not superstition. In the sense that calamitous events will descend on us because the rising sun happens to colour early morning clouds. It’s more the practical reality that British weather most often comes from the North Atlantic. So, clouds hovering in the West can be the signs of a cold front coming our way.

Being born in the countryside these ditties are bread and butter to me. Rural sayings about different times of the year, or nature in general endure, even in the mobile phone age. Now, up to date weather predictions, based on proven science are only a touch screen stroke away. Even so, memorable adages stick.

Last week, I heard a new one. New to me. A rhyming prognostic on the coming winter. This is not only a saying confined to rural areas. It adds to a long list of observations about the habits of birds.

This is not witchcraft. Birds’ behaviour can help us predict the weather, even if the means they use can be obscure. Our feathered friends are much more in-touch with nature than we can be.

“If the ice in November can bear a Duck. The rest of the Winter will be slush and muck”.

What’s going on with this traditional bird proverbs stumps me. OK, this suggest that a hard frost in November is an indicator that a warm, wet, and soggy winter is ahead. The duck as a measure of weight may be incidental. However, some ducks do migrate to find warmer places to overwinter. So, does the saying mean that because the duck is still here, it’s decided that the winter will be mild?

That’s contradictory to the presence of the thickness of ice needed to hold a three-pound bird. If a duck can stand on the ice and is happy with that situation. They are in the local park. Then that could mean a blast of cold air from the North before the year ends, has some meaning in terms of what happens next. What’s that got to do with slush and mush? I wonder.

Is this saying somehow linked to the past when hunting ducks was an annual event. Some strange observation that ducks are easier to hunt earlier in the winter. Or is that nonsense on my part.

This folklore saying about winter can be put to the test. Although we are close to the end of November, the frost has been hard enough to bear a duck. Not a huge duck but an average mallard.

If this means a mild winter, we’ll soon know. Maybe duck barometers will work as long-term predictors. Showing us a sign of coming foul weather. Ho, ho.

Overhead

Massive intertwining skyscrapers. Towering masts. Flying cars. Pulp magazines in the 50s and 60s had it all. Beautifully illustrated in bold colours. Sharp lines and chiselled faces. Heroic poses and streamlined transports.

Visions of the future. Idealistic imaginations of a utopian society. Don’t we just love them. That is until someone builds them in our neighbourhood. Until the bulldozers turn-up unannounced on a Sunday morning to root out the trees. The birds flee the vicinity (except the pigeons).

You can blame the draftsmen of the past if you like. In our heads there’s a disconnect between the images on a set of drawings and what that might become in concrete and steel. Grand designs are but few. A great deal of the building and planning of the last 60-years can justly be called dreadful.

We have an outcry over brutalist architecture or a lament about a Victorian park that has been paved over. Has anyone ever walked through a public car park that inspired?

If you dream it, you can make it. Nice phrase but often stifled because current technology and thinking are way behind the curve. It could be said that this is one of the drivers that pushes technology forward. The realising of dreams but who’s?

Where does the flying car fit in all this fiction and near realism? New forms of air mobility are just about to start operating.

It’s a habit of our times to jump to an instant polarised opinion. Those open toed sandalled greenies will object. Those red necked, but reforming petrol heads will welcome. That sort of stuff makes nice headlines. It’s only a basis for the crudest dialogue. Anticipate conflict and then fuel it with prejudice. Please, let’s avoid that pointless waste of time.

My thoughts are that the potential of the greater use of airborne transport is a nuanced.

Electrification is a pathway to more environmentally sustainable ways of moving around. If this helps to reduce miles of fuming traffic jams that must be good. At its best, flying can get people from point to point without having follow roads set-down at the time of the horse and cart. Accepted that concrete may be poured to create a take-off and landing zone but compare that with road building and there is no comparison.

On the more concerning side, contrast that with cluttering the skies up with fast moving machines.

In HHGTTG there’s a tale about a shoe event horizon. When gloom causes people to look down and so then buy new shoes to cheer themselves up. So, the whole economy switches to shoe production and then collapses as a result. The association with salvation coming from looking-up is there in the wit of Douglas Adams. We look up to cheer up.

If looking up, as I do at home, to see high altitude vapour trails crisscrossing the sky, my thought is – I wonder where they are going? On the days when a light aircraft crosses the town, to or from our local airfield that doesn’t bother me. Even a noisy police helicopter keeping an eye on the traffic. That’s fine because they are solely there for our safety and security.

What will be the public reaction when we look up to see half a dozen new urban mobility vehicles buzzing past overhead? Perhaps we’ll accept new flying machines if it’s for a public service, an ambulance, fire services, police, or even newsgathering. Brightly coloured in emergency orange.

A public flying taxi service might raise a few eyebrows. A flashy private flying car, now that might be another matter altogether. There you are on a hot summer evening, in the garden, having a pleasant barbeque with friends and whiz a flying car swoops over the treetops. The passengers have their mobile phone out filming their trip. This is when fist will be raised skyward. It’s a time when you hope the next-door farmer hasn’t got a shotgun.

Today, a few pilots do get prosecuted for misbehaving when low flying private helicopters. Not often, it’s true. This happens with less than 1500 helicopters registered in the UK. What would happen with, say, 10,000 private flying cars? I wonder.

Scary 2

My list is still open for horror in aviation. I’ve opened the door to action movies with elements of horror. I’m excluding war movies and fighter pilot romps. A dramatic scene must have a moment of suspense when everything hangs on a thread. It could be a hide behind the sofa moment or felling that all is lost, and the faint light of hope is dimming. I was tempted to include zombie movies only to quickly come to my senses and say – no. I’ve avoided Snakes on a Plane. One, because I haven’t seen it. Two, because it’s write-ups suggest that it’s too ridiculous for words. Although, it’s not impossible. It’s even happened on general aviation flights.

Here’s five more movies, ancient and modern in my private list.

There’s an adaptation of the book No Highway. With actors James Stewart and Marlene Dietrich in the movie you would have thought it would have been a big smash. No Highway in the Sky is pedestrian, but the tension comes from us knowing that metal fatigue is real. Why don’t they believe it? We know the history of the first commercial jet, the Comet aircraft.

The original Flight of the Phoenix is a great suspense movie[1]. It’s not so much horror as intensely griping. Frightening in the sense that it tells us something about the good and bad of human behaviour. The constant battle between despair and what can seem like hopeless optimism in the face of terrible odds. Through gargantuan effort, crash survivors stranded in a desert survive.

There’s something especially frightening about aircraft crashes and danger in the cold white wastes of the poles. Again, passengers and crew struggle to stay alive in freezing weather in the desperate hope of rescue. Stranded, death visits the unfortunate survivors. Ordeal in the Artic[2] is a chilling movie of 1993 based on real events in 1991.

Final Destination has simple plot[3]. A student has a premonition, he and his friends get thrown-off a flight to Europe and then when they are back in the terminal there’s a fatal crash. They cheat death. But that’s not the end. That set-up is the ultimate scary imagining. It’s the what if? It’s the question survivors of aircraft accidents must ask – why me?

The 1955 British movie The Night My Number Came Up[4] plays on a similar theme but this time a nightmare before a planned journey. A bad dream of an aircraft crash. Will it happen just as the dream predicts. You must watch to find out.

Generally, in films there’s so much pure aeronautical nonsense on display. Commercial aircraft do not fall out of the sky when struck by lightning, flight crews do not lose control at the first sign of trouble, fuel doesn’t explode for no reason and the worst of weather doesn’t signal game over.

That said, there’s an inherent claustrophobic feeling inside an aircraft fuselage. It’s like a locked room drama. Passengers are isolated from the outside world. They are dependent on pilots, engineers and air traffic controllers all doing their jobs right. There’s the potential for this set-up to be the stage for an excellent dramatic horror movie. Tales of bravery, camaraderie, and sacrifice can all spring from the most dreadful of events. Unfortunately, so many movie makers make a mess of these situations.
