A Bag of Contention

A lot has been said about passengers stopping to collect their cabin bags while escaping the blazing Aeroflot aircraft in Moscow last week. Some media went as far as blaming them for excessive deaths of those trapped behind them, with certain Russian politicians even urging to initiate criminal proceedings against those who stopped to pick their bags up (yes, in Russia, party still goes to you © Yakov Smirnoff).

The moral perspective of this complicated matter is unlikely to ever have any kind of satisfactory resolution. It goes deep into the pre-social parts of our brain, mostly cared for by instincts, reflexes, and fight-or-flight responses – and nature is extremely difficult to judge. In the moments of extreme stress and imminent risk of death, few people would think of anything other than their own salvation. The extent of that few depends on many factors, with different social groups balancing fight, flight, and collaborate differently, but it is crystal clear that we can’t blame people for acting selfishly when their lives are in danger.

That being said, there is no doubt that the problem must be dealt with, for the sake of our own future, first of all. Obviously, the collection of cabin bags did delay the evacuation (though the extent of its contribution is yet to be assessed – and I hope it will be assessed). Yet, what’s more important, is that should a similar accident happen again, in whatever town or country it might take place, the behaviour patterns of the escaping passengers are very likely to be highly similar to what we’ve observed in Sheremetyevo.

The fact is, the safety rules around hand luggage, both written and unwritten, are quite relaxed. Effectively, you can do whatever you like with your bags while on board as long as they fit into the airline’s allowance and don’t contain prohibited items. While pre-flight safety briefings advise you against taking your cabin bags with you during evacuation, this is hardly being enforced. It might be hard to resist the temptation to grab the bag that contains valuables such as your passport, phone, or laptop.

One of the reasons for that is that over the last few decades the role and concept of cabin luggage significantly changed – while the rules governing it remained largely the same. For the vast share of today’s passengers, their cabin bags are their primary and only luggage, especially on short-haul flights. It differs drastically from what it used to be twenty years ago, when most of carry-on items were jackets, overcoats, clutches, and an odd duty free bag, with the principal luggage checked into the aircraft hold. The hold itself acted as a physical security control: in case of an emergency, there was no way for the passengers to retrieve their bags. The small or useless carry-on items didn’t pose any risk of a slowdown during the evacuation. Conversely, most of hand luggage items today are stuffed-to-capacity purpose-made ‘cabin bags’, designed and manufactured specifically to ‘just fit’ into the measuring cages. This makes a huge difference, and this is the problem that must be addressed in the safety rules.

The abundance of bulky personal items on board the aircraft is even more complicated by the fact that with many airlines you can’t bring two cabin bags on board, however small the second one is. This forces you to fit everything you need to take with you into that single piece, mixing items of low and high value in one huge cabin suitcase. Should you need to evacuate, even if you would only intend to grab the high-value items, you would have no other option but to take the bulky low-value ones with you too.

So we need to find a convenient way to address those matters. We can’t make people not care about what they value (e.g. their passport) – but we can totally help them with leaving whatever they value less behind. For example, we could give the cabin crew the powers to lock the overhead cabin bag compartments for the whole duration of the flight, and at the same time extend the hand luggage policy to include a [much] smaller second bag. This second bag could be as small as a clutch, a belt bag, or a neck pouch – just enough to accommodate your passport, phone, and wallet.

Such approach would let passengers separate their items of importance (which in most cases are quite compact in size) from the less significant ones. It would introduce a security control in the form of a lockable overhead compartment, yet give passengers peace of mind that the items they value won’t be lost or destroyed should they need to evacuate.

One way or another, one thing that can be said for sure is that the question of aircraft evacuation and the role of hand luggage in it should not be shelved. The lessons of the Aeroflot crash should be learned, in particular in respect of hand luggage policies and procedures. We would be complete fools if we fail to admit the obvious and simply transfer the blame onto the survivors – since this would mean transferring the punishment onto our future selves.

Skill vs Technology: a zero-sum game?

Last week I came across two peculiar stories dedicated to the role played by technology in the evolution of the civil aviation industry. While the stories were barely related to each other at first glance – and had I come across them at different points in time I probably would have never spot that huge connection between them – but luckily I was still thinking about the first story when I bumped into the second one, and immediate realisation of the scale of the apparent trend made quite an impression on me.

That first story was about the role of technology in the crash of Air France transatlantic flight 447 back in 2009. The primary conclusion from the investigation that the article elaborates on is that the pilots were so got used to flying with assistance of the autopilot that they became completely lost when they faced the need to fly the aircraft manually. They’ve just got no understanding of the situation whatsoever, as they’ve lacked the hands-on feel for flying the aircraft at cruise altitudes – something normally handled by the autopilot. In addition to that, the autopilot, designed with intelligence and pilot-friendliness in mind, didn’t warn the pilots that the aircraft was approaching a complete stall, after interpreting the way-too-sharply plummeting speed as an indicator of a probable false alarm.

Confused and lost, the pilots applied several corrective actions to get the aircraft back on its course. Unfortunately, due to the pilots’ lack of situational awareness, those actions had become fatal. The A330 lost its airspeed and crashed into the ocean, killing all 228 people on board. Ironically, the investigation had shown that should the pilots not intervene in the situation, AF447 would have continued at its cruise altitude as it should even with its autopilot switched off.

The second story I read was on a far more positive side, depicting prospective transition of the London City airport air traffic control tower from the airfield itself to a small place called Swanwick, Hampshire, some 80 miles away. Specifically, twelve HD screens and a thick communication channel are going to be used to replace the existing watch tower, and are claimed to provide far better insight into aircraft landings and take-offs performed at the airport, as well as a number of augmented reality perks. The experience of LCY is then expected to be picked up by other airports around the country, effectively making air traffic control tower operations an outsourced business.

The fact that impressed me the most about these two articles was that they both, despite being barely related per se, are essentially telling us the same story, the story of skills typically attributed to humans being taken over by technology. It’s just that the first article tells us about the end of the story, while the second one is rather at the very beginning of it.

Just like such advances in technology as the glass cockpit and way-too-smart autopilots led to pilots losing their grip in manual flying, switching to augmented HD view of the runway will inevitably lead to air traffic control operators losing their basic skills, like tuning binoculars or assessing meteorological conditions by a dozen of nearly subconscious cues. The trained sharpness of their eyes, now supported by HD zoom, will most certainly diminish. Sooner or later, the operators will be unable to manage the runway efficiently without being assisted by the technology.

And this is the challenge we are going to face in the near future. The more human activities typically referred to as ‘acquired skills’ are going to be taken over by technology and automation, the less able we are going to be about those skills ourselves. If a muscle isn’t constantly trained, it wears off. If a musician stops playing regularly, she eventually loses her skill to improvise. If a cook doesn’t dedicate as much time to cooking, his food loses its character, despite cooked from the same quality ingredients and using the same proportions.

And that’s not necessarily bad. As the technology is inevitably making its way to our lives, taking over those of our skills which it can perform better than we do, there is no reason not to embrace it – but embrace thoughtfully, realising the consequences of us losing grip on them. Remember that we had lost a big deal of our skills to the past already. Your great-grandfather is very likely to had been particularly good in fox hunting, your grandad probably performed much better than you in fly fishing, and certainly a much wider proportion of population were capable in horse riding two centuries ago than it is today. Those skills had been taken away from us by technology and general obsolescence, but do we really need them today?

What we need though is to have a clear understanding of the consequences of sharing activities we got used to do with technology, and be prepared to observe a steep decline in the quality of our own respective hand skills as technology gradually takes them over. Understanding that problem alone and taking our imperfect human nature as it is will most certainly help us manage the risks around technological advances more efficiently.
