Human Factors in Ultra-Long Haul Air Travel
Human Factors in Ultra-Long Haul Air Travel
It is generally agreed that non-stop flights to places like London – Sydney are well within the range of technical possibility, but the economics still prove elusive. As the industry and passengers work through the practical issues to make such “ultra-long haul” travel possible, what are the human factors and ergonomics that will be required to make passengers more comfortable without sacrificing yield?
The latest generation of airliners already goes a long way to addressing some of these issues. For instance, with the new generation of Boeing airpcraft, two of the most important issues related to passenger and crew comfort have been addressed in new and innovative ways.
The question of relative humidity and air quality on the new Dreamliner series of aircraft show a great deal of potential for increasing passenger comfort on any flight segment. While most commercial aircraft in operation today can give passengers a perfectly acceptable level of atmospheric conditions (equivalent to those at approximately 2,700 meters (9,000 feet) above sea level) there are some bio-dynamic stresses that such altitudes place on the body.*
The new Dreamliner claims to be able to deliver a cabin atmosphere of approximately 1,800 meters (6,000 feet) above sea level, which would represent a major increase in overall cabin air quality when measured in terms of relative humidity and constant oxygen content. Boeing claims that there is almost no difference between 1, 800 metres and sea level, although some of us who ski or hike may beg to differ just a little. Either way, this could mean a significant reduction in overall passenger comfort as well as lessen flight fatigue, making these ultra-long haul sectors more appealing.
In addition, there are a number of new cabin LOPAs (Layout of Passenger Accomodation) that in my opinion represent innovative moves forward for passenger comfort. Some of my personal favourites across all cabins include:
· The new “Sky Couch” being rolled out by Air New Zealand, and designed by Altitude Interiors. I am intrigued by the overall concept of offering this new product in the economy cabin, and believe that it represents a step change in cabin interior innovation for families, couples, and even individual passengers. I look forward to seeing how the economics of this new product play out in the marketplace.
· I am also truly impressed with the new British Airways First product. This collaboration between BA, B/E Aerospace, and Tangerine Design. While the aesthetic is pleasing, what I appreciate most about the new product is the increase in the shoulder width available to the passenger when reclined fully into the flat-bed. This detail alone sets this new seat and LOPA apart from other competing herring-bone products which I feel do not offer the same shoulder comfort for those passengers who might have a slightly different build from your average European passenger.
· I would also be remiss if I did not mention the existing and just emerging LOPAs for the A380 aircraft. From Singapore Airlines, Air France, and Emirates each new delivery seems to bring us something new and game changing in each of the cabins.
· I also believe that the new SWISS First and Business product built in collaboration with Sicma Aero offers trans-continental passengers a new and very comfortable experience in both cabins. From the very Swiss design incorporating the lightly coloured woods and whites, to the luxurious First Class suites, I feel there is potential here for these designs in ultra long haul aircraft as well.
On feature of particular value to the passenger in the know is the Business Class product: Row K. A lone Business Class Seat on the left of the aircraft, with generous personal space to your right, it exceeded all expectations.
Overall, I think that the major issue with ultra-long haul will be with the new aircraft and the emerging balance of new LOPAs and the unique yield opportunities that some of these innovations represent. It is my sincere belief that “fortune favours the brave” and that we continue to see cabin innovations of this quality for a long time to come.

Tokyo Tragedy
- What happened to the FedEx MD11?
- What is the impact to Narita Airport and to Passengers?
- Some real-time passenger stories
- Our Summary of the situation

The Departure Boards at Narita today had to be watched closely, as they changed frequently and generally for the worse.
Having just arrived in Tokyo on Sunday evening, I can personally attest to how the winds were already causing a few delays on the arrival of our flight from London. As we approached Runway 34L the on-board “birds eye view” camera gave us a wonderful view of the runway as we pitched slightly from side-to-side. I often forget how tired you can be after nearly twelve hours on an airplane. I was to learn today, however, that my long trip was nothing in comparison to what some passengers were about to go through.
I was awake at 0500, as travellers often do on long trips. My wife and I got up and wandered around the early morning streets of Tokyo. While still a little dark, the wind was howling through the clean streets of the city. Having watched a bit of the local news earlier, we had heard it was going to be a beautiful day, but the Japanese Meteorological Service had issued a warning for high-winds through the Tokyo area.
What happened?
Then this morning at approximately 0650 Tokyo London time, FedEx Flight 80 from Guangzhou, China was landing at Tokyo Narita. As the MD11 flared up, just before touching down, the aircraft appeared to come down onto the runway in an uncontrolled manner. Bouncing up again only to clip its wing causing the aircraft to fatally lose control and in a fiery explosion come to rest with the front of the fuselage turned upside down.

We watched in horror as the Japanese fire and rescue response was immediate and efficient, and it took the fire-fighters just under an hour to cut their way into the MD11’s cockpit area to rescue the two pilots. While initial reports from the Japanese Fire Services advised that both the pilots were alive after being extracted, they later both later died.
The impact of this tragic event is being felt at Tokyo Narita, not only by the Fire and Rescue Services, but also by the passengers. The closure of one of the runways at Japan’s busiest airport is having a serious ripple effect on travellers.
While waiting at Tokyo Station for the Airport Express train I met the Hanson family from New York. Doug and Anna Maria Hanson were booked to travel today on JAL’s flight to Honolulu. They, and their two teenage daughters, had been travelling the world for over a month visiting South America and Asia. They had just finished enjoying a one week stay in Tokyo and said “We are looking forward to the Hawaii portion of their trip.” Now as we approach Narita airport the Hanson’s are not sure if they will be going at all today.

I am fairly certain the Hanson's did not make it today.
Anna Maria said, “It is a terrible tragedy. If there is a delay, we can handle it.” They had the air of seasoned travellers. When asked what she thought of their trip so far, she said, “People we have met here in Japan, and in Asian countries in general, have been among the most polite and organised that we have encountered. I am sure that we will find a way to make it to Honolulu.”
The Departures Hall was full of queues that one might expect, and on the far side of the airport check-in area, the queue for the information desks was full of passengers and their baggage that were not heading anywhere, at least for today. In typical Japanese fashion, everything was calm, and orderly, and there were plenty of airport staff available to answer questions and direct passengers.
At Narita I met William Oliver, a British businessman who came to Tokyo last week for meetings and stayed over the weekend to do some sight-seeing. Learning that his flight home JAL flight, JL401 to London was now cancelled he said, “I wish I had just gone home as originally planned; but there is nothing for it is there? Understandably, and for obvious reasons, there is just not another airplane available“ He said that his airline has been very accommodating, and helpful, “… but I am still not sure how, or when, I am returning home.”

The arrivals board told the story of the diverted and cancelled inbound flights. Despite the cancellations, some flights did arrive several hours late.
What could be worse than not being able to get a flight out of Tokyo?
The news is actually worse for those who were already heading for Tokyo, especially for passengers who were in the air and on their way from European destinations. Generally these flights are set to arrive in the afternoon. Flights from the UK, Germany, and the Gulf Region are particularly affected. In the case of JAL’s London inbound flight, it was diverted to Nagoya airport. Some flights have been diverted as far away as Sapporo on the north island of Hokkaido, not an easy rail trip for passengers.
There were a few passengers who were luckier, and were diverted to Central Japan. I spoke to Jennifer Tolliver, a University student from Liverpool, as she was slumped over a cup of coffee in the Departures Hall. Bleary-eyed she relayed the story of how she was on her way to China to visit friends, and had chosen to fly via Tokyo to save money. “Our flight was diverted to Nagoya. I had no idea where exactly that was in Japan. Now, I have had to spend so much time and money on a train ticket that I could have just flown directly.” Her airline has managed to get her another flight later tonight, but with all of the other cancellations she voiced a concern that she would actually be able to make it. “I am just afraid I will need to spend more money for a hotel, if I can even find one.”
Emily Logan, a Australian on an extended “around the world trip” had been helped out significantly by her airline. Her next stop is San Francisco, and JAL was able to transfer her to a Cathay Pacific flight leaving tomorrow via Hong Kong. “We are not actually upset, but we are little annoyed that we are going to miss so much of our time in San Francisco.” At one point an airline representative had told her that things may not return to normal at Narita until Thursday. While we were speaking her travelling companion was on the phone checking to see if their travel insurance would cover extra expenses in this particular situation.

The International Arrivals hall would normally be full at this hour on a Monday
As I stood in the nearly empty Arrivals Hall on what should be a busy Monday night, watching the cancellations, an automated message was playing overhead. “The NAA (Narita Airport Authority) is advising that some aircraft have been diverted for operational reasons. Please contact your airline for further information, and we apologise for any inconvenience.”
Nothing to apologise for, but plenty of other emotions to express.
In my opinion, there is nothing to apologise for. I personally observed the Japanese Authorities, the airport, and the airlines handling issues and doing their best given the tragedy that they are also dealing with. While everyone I spoke to may have been inconvenienced, and it may take days for Narita to return to normal, people were still acutely aware that two pilots lost their lives today. That puts it all in perspective.
From all of us at TWC, we wish the FedEx pilots friends, family, and co-workers our sincere condolences for their loss. To the brave firefighters and rescuers who tried their best to reach the pilots in time, we stand in awe of your bravery.
