Autotraffic

Driving back from Christmas. That’s not a Chris Rea song. Although, he did write “Driving home for Christmas[1]” while stuck in heavy traffic. I expect the feelings are similar – moving down the line. It took some time. Redlights flickering everywhere. Looking at the drivers next to me – looking just like me. Looking stoic or miserable or both.

Our carborne irritations were trivial when compared with the conditions in Scotland. We didn’t get 80 mph winds. At least the snail’s pace of the traffic on the main A303 was a snail’s pace. Inch by inch we moved closer to where we wanted to be. No streetlights on the jammed part of the A303, yesterday. The light went up and down with the heavy cloud cover. Colours ranging from gloomy grey to even gloomier dark grey.

Windborne debris, litter, like discarded crisp packets, set off on journeys of their own. Waterfilled potholes blended into the grey of everything. Crushed traffic bollards popped up as if they were growing amongst the sodden grass verges. Occasional motorcyclists took their life in the hands as they weaved amongst dozy drivers.

In the stationary moments my mind wandered. Who were those people dressed in the storm gear doing the tourist march around Stonehenge? They were not going to give up one moment of their vacation. What’s a blizzard of rain comparted to a once in a lifetime trip around ancient stones?

I got to thinking – how would this work if half the cars around me were automated? Human behaviour is pretty erratic. Driver temperament goes from kind and generous to intensely mean. From the laidback CofE vicar to the road rage professional. The circumstance of the drivers is hugely different too. One may be surrounded by screaming children while another is lone, absorbed in their favourite podcast. The first is a couple of hours into the worst drive of their entire lives. The second is in no hurry and happy for the day to drift by.

I sincerely hope that the makers and promoters of “driverless” cars take the human factor seriously. We know enough from aviation to know that the interaction between humans and semi-automated machines is exceedingly complex. That’s in situations where operating procedures are tightly controlled and monitored.

It’s one thing for car makers to rattle on about the importance of safety, it’s another for promises to meet the road. I’d say this is particularly true for the average British main road. Given its provenance there’s an excruciating number of variables. A truly dynamic set of variables that increase dramatically with speed. Weather goes from plus thirty summers to minus ten ice packs. Worn white lines come and go. Grass verges overhang the carriage way. Tarmac cracks and puddles compete with mud sloshing across the road in the heavy rain. Magpies dart into the road to munch the carcass of a dead hedgehog. The one that didn’t make it across the road.

Human drivers compensate for all the imperfections because that’s just what we do. It’s amazing even what the worst of us do. On the other hand, machines must characterise every single non-standard situation with accuracy, reliability and at great speed. Next time, I’m driving home for Christmas it will be manual. Likely, for a decade more too.

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.

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.

Tip

You may think it was a bit of a joke. Certainly, some of the holiday makers around me thought the cabin crew were joking. I was at the back of the aeroplane and so one of the last passengers off.

We arrived at London Gatwick’s North Terminal at about 9:30 pm on a Sunday. Passengers were keen to get off and get home. That said, the amount of sizable luggage in the aircraft cabin overhead bins and maybe the sleepiness of one or two people meant the long line down the aisle was moving slowly and intermittently. The process was civilised but at a snail’s pace as it seemed from the back.

When you hear a request to hurry-up otherwise the plane will tip up it does instil some urgency. That and one or two questions. It also made me think; could that really happen in this situation? I was standing next to the cabin crew at the back, and I can attest to their concern being real. Being at the terminal gate there was only the front door open to exist the aircraft. When we got on-board the aircraft both the front and rear doors were available.

The Boeing 737 MAX-8 is a not an overly long aircraft. That said, under certain unfavourable conditions it can tip. In fact, there are longer versions of both the Boeing and Airbus single aisle aircraft that pose more of a challenge in this respect. There is much stretching of popular aircraft types to increase passenger capacity.

At the same time as we were deplaning[1] (ghastly word), the ground crew were unloading our luggage. As a result of all this movement of passengers and luggage it is possible to have too much weight at the back of the aircraft. Yes, you could blame it on masses of carry-on bags obstructing the aisle on a full aircraft, but it also takes the front passengers to have got off quickly. There are more passenger seats behind the aircraft wings than there are in front. On a cool Sunday evening when the airport’s public transport options are limited there’s an incentive to rush-off from the front. As the deplaning continued there was a sense that something was happening underfoot.

Does it happen? Do aircraft tip up? Yes, they do[2]. It’s not an attractive sight. I have no idea what the procedures are if it does happen. It certainly would be a shock for those on-board. Anyone in the vicinity of the aircraft would have to watch out too. In these unplanned events, there is a hazard to ground crew that can result in injury.

This sort of event happens more often in the air cargo world[3]. While these events maybe comical to witness, they are no joke for airlines. The possibility of damage and the disruption to aircraft operations can be significant. Nose wheels coming off the ground don’t always result in an aircraft tip, but this is not somewhere any crew responsible would want to go.

Weight and balance issues are real. Each aircraft will have weight and centre of gravity limits established at the time of aircraft certification. Aircraft operators will have procedures[4] that fully consider loading and unloading. That said, as we can see, miscalculations do get made.

Bad Seat

There’re bus trips, I can recount where people were packed in like sardines in hot sweaty environments. Never a pleasant situation but, in such circumstances, a way of getting from A to B. Maybe the only way of taking an essential journey. Life’s necessities.

I could rattle off the mantra “any safe flight is a good flight” and that remains true. It’s top of our normal priorities. Getting from A to B in one piece. No harm done. It’s the homing pigeon in all of us. I’ll put up with this unpleasantness because it gets me home.

Last night, I had that experience. It was my first flight on a Boeing 737 MAX. I’m not going to recount the saga of that aircraft type over the last couple of years. Much as to say, I reassured a nervous flyer with me that she was quite safe and nothing bad would happen. That is bar a small amount of turbulence in our three and a half hours in-flight.

I was returning from Preveza-Lefkas [PVK] to London Gatwick [LGW] on a TUi package flight. We got into Gatwick at about 9:30 pm with a full aircraft. The temperature change of having gone from a day of sunshine and about 28 degrees C in Greece to 6 degrees C and darkness on the ground at Gatwick was quite a shock. I must admit I was prepared with three layers to keep me warm.

What I want to recount is the gross unpleasantness of seat 32D. Row 32 is the last row of passenger seats in the aircraft cabin, with two toilets behind. By the way seat 32E is just as bad.

The aircraft was chock full of holiday makers returning home. Bags full and overhead bins stuffed. This shiny new Boeing 737 was fuller than anticipated. Left on the tarmac was an EasyJet aircraft that had been expected to depart earlier in the day. It had “gone technical” – as they say. So, to get home, many passengers had transferred to the later TUi flight ensuing that every aircraft seat was full.

Now, given that I’d checked-in for my return home flight in good time and I have no idea why TUi decided to punish me. I should have spotted that 32D meant the last row of seats. But you know how it is, it was enough to get that bit of administration behind me and carry on enjoying the day.

My intention was to do what I do well, at least in the past and that’s to get some sleep on an uneventful evening flight. I was ready to sit back and wander off to dreamland hoping to wake as the aircraft wheels hit the ground back at Gatwick airport. Unfortunately, I wasn’t to be given that opportunity last night.

Toilet flush motors are not silent. With a full aircraft, and three and a half hours the toilet traffic was almost continuous. The sequence of noises had a horrible rhythm. Door open. Clack of the door latch or fumbling around as a passenger worked out how to close the toilet door. Maybe even a few words with another passenger who block the aisle. Then the clank of the toilet seat. Maybe the walls get bumped as awkward manoeuvrings took place. There was no stop to this soundscape of lavatorial processes, ablutions, and choreographies.

It’s so British to que. When the trollies were not being pushed up and down the aisle, the aisle filled up with passengers waiting for the loos. Then those returning to their seats had to squeeze past the assembled que. Naturally, the 32nd row aisle seats got to see every kind of human shape and form. Trying to ignore a rear end sliding past your face gets tedious when it happens a lot.

That’s not all. When the toilet doors swing wide open, they bump against the back of seats 32D or 32E. What a mad design or stupid afterthought.

Then there’s the issue of well used aircraft toilet facilities, even on a new aircraft. They may start off as sweat smelling as the air freshener applied. After a few hours of constant use, they are nothing like sweat smelling.

My overall message is – when flying on a Boeing 737 MAX, do not accept passenger seats 32D or 32E unless you have been a very bad person and deserve punishment. Ideally, a good airline would remove these two seats altogether but to make such a suggestion is to p*** in the wind.

HS2 – again

Travelled on the Elizabeth Line yesterday. It was an expensive project to build. Tunnelling under London and erecting new stations was a costly business. It was called “Crossrail”. Approval was given in 2007 and construction started in 2009[1]. In 2022, one-sixth of the UK’s total rail journeys took place on the Elizabeth Line. The billions spent were a major investment in the future. Over £18 billion in fact. It was a national demonstration that huge civil engineering projects can be undertaken and mastered[2].

As a passenger the Elizabeth Line is a pleasure to use. It’s clean, speedy, and simple to use. Comparing it to the older London Tube lines is like comparing a Tesla with a Ford Anglia[3]. Sadly, a great deal of our national rail infrastructure is trapped in the Ford Anglia era.

So, what of HS2[4]? The wibbling and wobbling that has plagued the project is sucking the energy out of the resolve needed to see through an even bigger undertaking than Crossrail. Some people argue that the billions needed for HS2 could be better spent on other projects. However, the portfolio of transport projects that are suggested as alternatives never seem to materialise.

Talk of cancellations feed the political turbulence over infrastructure investments. The impression this presents goes way beyond the shores of this country. There’s no Global Britain on show here. It’s more signals of dither and lack of determination that are publicly on display. Instability and the short-term outlook is the motif of the current generation of politicians.

If there are superior and smarter alternatives to HS2 they should have come up during the planning phase of the project. What we know about vast engineering projects is that chopping and changing them midstream adds massively to costs. It also diminishes the usefulness of the outcome.

Britain needs a backbone. A rail backbone and a political backbone. The spending on HS2 is large but that spending is in country. It’s jobs and investment onshore for the benefit of the whole country, not just the Southeast of England.

The last few years have seen that banner “levelling up” heralded by Conservative politicians. This slogan will be as nothing if HS2 is wound down or constricted. The signal will be loudly heard that all that talk of levelling up the regions of Britain was shadow boxing.

In the long-term improved connectivity across the country will be a great asset. The Victorians knew a thing or two about engineering great projects. Their legacy should give us resolve.

NATS

A “technical issue” has caused UK National Air Traffic Services, NATS to impose air traffic flow restrictions[1]. They did not close UK airspace. This was not a repeat of the volcanic ash events of early 2010. Going from a fully automated system to a fully manual system had the dramatic impact that might be expected. The consequences, on one of the busiest weekends in the holiday calendar were extremely significant. Huge numbers of people have had their travel disrupted. Restricting the air traffic system ensured that aviation safety was maintained. The costs came to the UK’s air traffic handling capacity and that meant delays and cancelled flights.

Although the failures that caused the air traffic restriction were quickly resolved the time to recover from this incident meant it had a long tail. Lots of spoilt holidays and messed up travel plans.

It is normal for an Air Traffic Service (ATS) provider to undertake a common cause failure analysis. This is to identify multiple failures that may result from one event. So, the early public explanations coming from NATS of the causes of this major incident are surprising. Across the globe, contingency planning is a requirement for ATS. The requirement for the development, promulgation and application of contingency plans is called up in international standards, namely ICAO Annex 11.

So, the story that a single piece of flight data brought down the traffic handling capacity of a safety related system, to such a low level, is difficult to accept. It’s evident that there is redundancy in the systems of NATS, but it seems to be woefully inadequate when faced with reality. ATS comprise of people, procedures, and systems. Each has a role to play. Safety of operations comes first in priority and then air traffic handling capacity. What we know about even highly trained people and data entry is that human error is an everyday issue. System design and implementation needs to be robust enough to accommodate this fact. So, again attributing such a highly disruptive event to one set of incorrect data inputs does not chime with good practice or basic aviation safety management. It is concerning that one action can bring down a major network in this way.

EUROCONTROL would have had been sent a “rogue” flight plan in the same way as UK NATS. Brussels does not seem to have had the problems of the UK.

It is early days in respect of any detailed technical investigation. Drawing conclusions, whatever is said in public by senior officials may not be the best thing to do.

Calls for compensation have a good basis for proceeding. The holiday flight chaos across Europe comes down to one single failure, if initial reports are correct. That can not be acceptable. The incident left thousands stranded abroad with high costs to pay to get home.

Before privatisation, there was a time when the UK Civil Aviation Authority (CAA), ran the nation’s air traffic services[2]. It had a poor reputation at the time. I remember a popular newspaper cartoon saying – and now for some clowns from the CAA. They were entertaining delayed passengers.

UK NATS has done much good work to manage a safe expansion in air traffic and address many changes in technology, it would be a shame if this sad incident marks a decline in overall network performance.

NOTE 1: And this topical cartoon from the Daily Mail in April 2002: https://www.pinterest.es/pin/497577458805993023/

NOTE 2: A report on the incident is to be sent to the regulator, UK CAA on Monday, 6th September. Transport secretary to see Nats’ ATC meltdown report next week | Travel Weekly

NOTE 3: The likelihood of one in 15 million sounds like a low number but it’s not “incredibly rare” by any definition. Certainty when there are around 6000 flights a day in the UK. A duplicate error occurring is a basic error that could be anticipated.

First Flight

I didn’t have a gap year. That’s a year a student takes off their studies. It was a fashionable rite of passage. These days a gap year is often associated with an opportunity to gain extra skills and experiences to add to a CV. Going back to the early 1980s, after all we still had local authority educational grants, a gap year was associated with travel and adventure.

What I did have was employment. As a sponsored student, I had an income whilst working and a bursary. So, although my student grant was highly variable. My parents were self-employed. I was reasonably independent and well off for the average undergraduate student. That was a benefit of being in demand in the engineering world. Not only that but in the recession struck West Midlands our student cost of living was within our means. With a care in spending and cash-and-carry[1] shopping it was possible to put money aside.

It was August 1981, when I took my first passenger flight from London Heathrow (LHR). It wasn’t a modest hop over to France or a Greek sunny beach but a Pan Am transatlantic international adventure to Seattle (SEA). Long-haul, a long way in a classic Boeing 747. Flight PA 123 out and PA 122 back.

This trip came to mind yesterday lunchtime as I was sitting in a stark modern Starbucks coffee shop. Yes, there was a time when such places were exciting, special, new and off-beat.

In a way this journey did enhance my education studies. One part of the trip was a visit to a steel factory in Los Angeles (Plessey Precision Metals). Now, that was educational. The boss who showed me around was forthcoming about where their labour came from and the working conditions.

Four of us Coventry students went on this great American adventure. Basically, the plan was to arrive and depart from Seattle but to drive up and down the West Coast. It was a fly /drive package. By sharing the driving and staying in the cheapest motels we travelled a long way for our money. In massive contrast to the present day, the pound – dollar was at about 2.4.

42 years ago, the world was a different place. Although, breakfast at Dennys probably hasn’t changed. It was the year President Ronald Reagan sacked thousands of striking air-traffic controllers when they ignored his order to return to work. What a year to be flying.

Driving an AMC Concord[2] well over 6000 miles our trip was non-stop. A day here, a day there and, if my memory serves me right, a night sleeping in the car. That was in the mist over San Francisco.

Mount St. Helens had erupted in March 1980. We drove the rental car as close as we could to the areas of devastation to have a look for ourselves. It was dramatic. Trees felled like matchsticks. Grey dirt and dust covering the land. Signs of the eruption stretched far and wide.

If you can marshal the time and the money, have some good friends and are 21 years old, I can’t think of a better recommendation.

[1] That’s when my taste for peanut butter developed.

Luggage

It’s a space we have control over. Not a house or a room but, most often, a volume of space no greater than what we take up in our human frame. It’s not organic. It’s far from that because its role is security, storage and logistical. That’s the humble suitcase, and a great array of bags and backpacks that help us get from A to B with enough possessions to make life comfortable.

The choice of a suitcase or bag is not a trivial matter. Lessons from experience range from bursting zips to leaking contents that turn favourite clothes into damp rags. The challenge of replacing a cabin bag or case takes research and careful weighing of multiple options.

If traveling by air, there are numerous constraints on size and weight. A completely free choice as far as colour is concerned but that’s about the only characteristic that’s an open book. That said, it’s astonishing how many black cases look like other black cases in the array of black cases.

More than a decade ago airlines started charging extra for hold luggage on top of their basic fares. Since then, flying with hand luggage only has become popular. This trend can be troubling. Watching passengers squeeze unreasonably sized bags into overhead bins is not an entertainment. The expectation that an aircraft overhead bin can take a massive bag is not a reasonable one.

My latest purchase has been made from recycled plastic bottles. Naturally, that conveys a fell good factor. It’s a great way to give new life to the huge numbers of discarded single use plastic bottles that somehow we’ve become dependent upon. In my childhood, I don’t remember any plastic bottles. Plenty of glass but no plastics.

For short journeys, the faff of checking-in a suitcase, waiting to collect at a baggage belt and paying additional fees is a burden that is sometimes not worth carrying. There’s always the delightful experience of never seeing the case and its contents again as it wanders off into the maze of lost objects airports accumulate. Etched into my memory, even after more years than I care to think about, is arriving at a small airport after a tortuous journey of connections and having nothing but the clothes I stood up in. On a Sunday, in 35C degrees of bright summer sun that’s not an experience I want to ever repeat. Especially with a tough meeting planned for early the next day. A free airline toothbrush was no compensation.

So, I now have a new Cabin Max Metz 20 litre RPET backpack. This is an experiment on my part. Can I live out of this tiny space for 4-days? To do so is going to require some innovative thinking. In theory, it ticks all the boxes that I was considering essential. This backpack is lightweight but offers the maximum amount of packing space given an airline’s cabin bag restriction.

The plastic material the bag is made of doesn’t feel nice, but it’s flexible and hopefully durable. The zippers look substantial and should have a long life. Now, the task is mine. How to choose exactly the necessities of life to enjoy the journey ahead. To pack as smartly as smart can be.
