Seats



Seats are what you pay for on your airline ticket. Seats are what makes your journey special. A Seat is not a “single engine air tanker”, it’s your room as your travel the world. Two items make up your seat that directly relate to your ticket price. Seat Weight and cubic meters needed in your rented space. A luxury seat may cost 200.000 dollars and weigh a quarter ton in accessories. It may take up the space what three people have in economy. Or it may be in economy demanding several items:

·       Accessibility
·       Personal Space
·       Comfort
·       Command and Control options during travel.


Before we go gonzo on luxury seats, it is more productive discussing what 80% of the traveler will encounter in economy. Beginning with accessibility is the primary frontal lobe experience you will have boarding and the last thing you remember when leaving the aircraft. Many airline have a cattle call when loading passengers then the frenzy builds as everyone rushes the line as if somehow if in line first will make a journey better. Sometimes it does improve the experience by getting in line first.

However, Airline loading will help the passenger’s first impression last in a good way, if they do a couple of things. First drop the row call out and go into a vertical mode and alphabet soup it. In a nine across seat alignment. Call window and aisle center seats by letter. First all tickets with seat letters having “A, E, and I” are ready to board. The windows and center seats fill first no matter the row. Follow with letters “B, and H” second and all aisle seats last. Or at least color the tickets with its seat according to color code. Example rows 33-44 color code green board now and so forth. This would stop the passenger climbing over your face as you try to drop down your tray or look at an airline magazine.

Save first class for last, since they pay good money not to have economy class parade by them in one gigantic stream. In fact put them in a separate terminal lounge seat with the same seat number in waiting with valet service, since they will load last just the same, it will make the whole process more efficient and reduce the jungle warfare on seating passengers. Since it’s the bane of starting a journey having people walk over you to get to its seat make it civil and convenient. The Airline will achieve a great impression, (SWA).

Personal space can be achieved through the new slim line seats. More is created out of less. It protects the passenger experience giving them a place of functionality for long trips. All your travel interaction is protect by the seat. The person front or behind can’t harass your experience. The lateral incursion of your seat mates are cut-off in a flanking structure giving you privacy you may desire or it can open up as all inclusive when sitting with loved ones.

Ah, comfort is what it is all about. Pitch comes to play, space is gained in the seat in front of you as can accept your feet under the seat in front of you. Also the seat in front has enough room to store something else under its seat. It becomes a sense of personal space and flexibility for accessing the devices or taking a long nap.

The mid-flight embarrassment is encountered when at some point you need to “go” and you have two more seat mates to get over. Everyone watches out of boredom and how you will handle the feat, because they have to go too. Once again the seat must come to the rescue of passengers who have to “go”. The window or center seat passengers should be able to toggle a button for exit which informs the passengers in the way, by vibration, someone needs to exit. They in-turn can slide its slime line seat back and upward within the frame, creating space for a passenger to exit without imposing on the back or front of passengers space. A semi standing room maker seat without having passengers get out and standing in the aisle, it makes room for the stressed passenger. It could be even power driven seat, making it effortless to do the deed. You barely need to wake up to make it happen. I may be crazy for this kind of concept but I still got to go sometime.


The command and control method is a civil way to travel.

Transcending The 787 From The Back Door, A330 NEO

Slap a NEO on the A330 frame and you have an A330 NEO. A derivative of 787 engine technology, implants some 787 like metrics without using a clean sheet change out, or a new model class for Airbus. The advantage for Airbus is quickly summarized on balance sheets. How many gallons of Jet A can a customer buy from cheaper capitalization cost on one A330 NEO over buying the 787? If the answer is,  $20 million US dollars, then 10 million gallons of Jet A is bought with current prices becomes a number of significance and a Airbus selling point. If twenty-five thousand gallons is loaded on a Trans-Atlantic flight for an A330 NEO then it cost about $50, 000 dollars as a full load. But it will load something specific for its range and weight metrics with a standard safety margin within economic measures. Even if you go 70 % fuel capacity for an extended range trip of up to five thousand miles, the gallons will convert to about 15, 000 gallons or about $30,000 dollars fuel costs for one trip. Buying an A330 Neo with a new 787 type engine evolution will take the A330 even further.

As an A330 is sold for 20 million cheaper than the 787, you have tapped into capitalization savings and interest averted with the significant lower cost of buying cheaper. That too buys a lot of fuel for a less efficient aircraft than the 787. If the A330 NEO is 10% less efficient than the 787, as a number for this exercise, then an A330 NEO airline will slid slowly backward against the 787 performance, but it will have that $20 million advantage on price, as it uses its Extended Operational Cost Advantage (EOCA). A fancy way of saying, "we are leveraging the bargain". The metric also includes interest on capitalization investment, which also buys more fuel making-up the 10% efficiency margin the 787 has over the A330 NEO. The 10% percent fuel efficiency of the 787 over the A330 NEO and its 20 Million less cost, signals an A330 can fly for a long time within its routes at the same competitive nature of the 787 using the EOPA model. Here is how:


10 % fuel efficiency on an average, is on a load of 15,000 gallons on a medium route, (4,500 miles), which includes 1,500 gallons or more needed for the A330 NEO than the 787. At $2.00 (US dollars) a gallon, buying 1,500 (10% margin) more gallons for the A330 NEO cost about $3,000 dollars.  This amount divided into 20 million from its purchase savings, plus capitalization interest saved, means the A330 can fly about 7,000 different times on routes, before even approaching going into the red against the 787 in a daily comparison, of the bank accounts. Tack on a “baggage fee charge” (sneaky) on 250 tickets for $12, and the A330 NEO can buy the additional fuel margin lost to the 787. It will always stay even with the 787 on the bottom line. These are very rough numbers, but it is the selling or talking points Airbus uses when selling the A330 NEO. You can have a cheap 787 knock-off in the A330 NEO, and make money like a 787. Airbus is hoping for any lower tier and emerging Airlines will buy it.

A-380 is A Saturated order Book While The A350-1000 Wants The Table Scraps

How many more A380's will Airbus sell in light of its A350-1000 push? Qatar pushed back on the A-350 without cause, and is silent with an unannounced reason. Most think it’s business as usual for Qatar. After all they are known for leveraging Boeing into compliance from asserting customer preferences before delivery.

Evidently they (Airbus) must have made a deal with its customer, squeezing some monetary gain for Qatar. Where in return, it will zip it up and not say anything! Boeing couldn't foresee a Qatar hostage advertising scenario, before its first 787-8 delivery. Qatar made Boeing make it right or no delivery, plus they broadcast its displeasure, as if it were some kind of advertising junket using its displeasure concerning Boeing imperfections.

It proudly reports how exacting and conscientious they are over its aircraft. Once again it appears, Qatar has Airbus by the vitals between its fore finger and thumb in a pincher movement. It will squeeze more out of Airbus, as pride has a price in Paris.

Bloomberg News:


The infamous Airbus Hat-In-Hand surge in Airplane Wars

What is really happening is hushed money is paid in some kind of. "In kind payment" from the Airbus production line level? Where in Boeing's case it trusted everything, and it was good to go before Qatar played its cards. What is not known, is what cards does Qatar hold, a two of Hearts or Ace of Spades? The two of Hearts is a Boeing card, and the Ace of Spades would be something fundamentally wrong with the Airbus A350 offering. Qatar is holding its card tight to the chest. I always take the somewhere in between card, and I think it’s a well-played Joker on Airbus as they are fighting A380 order stagnation, and overly aggressive investment commitments for all its types, tempered by sales parity with Boeing. The investment analysis is simple, too many plates are spinning in the air at the same time as the 787 market presence grows beyond 200, 787 in service.

An industry rethink is occurring. It is filed under fickle next to the pickle.

  • Can the 777X straddle the A350 and the A380 conveniently?
  • Will the 787-9 and -10 make more market perfect fits than the A350 family?
  • Is the A380 in an Airport Pickle?
  • Is Qatar stalling on the A350 in its rethink?

That is enough questions for any press conference held in abstention. Here are some important general thoughts on these bullet points.

The 777X is of great concern for Airbus, once it takes to the air, and once its full metrics are validated. It will haul 80% of the passenger payload of the A380 but will fit in every major airport in the world. 

The 787-9 and -10 family will bisect the A350 market in pieces. Even the 787-8 has a Max capacity configuration for economy travelers going worldwide. The 787-8 carries from 291-335 passengers on week-end wonder routes. The 787-9 does that sensibly appointed. The 787-10 is a high density route maker with a 7,200 mile capability. Even though the A380 can go farther and carry more passengers economically. Only 10% of the world's route needs that kind of density and distance. 

However, the 777X can capture that 10% of the market without airport renovations at either end of the route. There is the major re-think airlines are undergoing at a crucial time for both the A380 and A350. The question remains which tool box do we want to own, Airbus or Boeing? Re-thinking is now critical for this important answer. The Qatar order delay may be more important than installing the right seat colors. It may be a prevent defense milking the order clock as it ponders the order log, before orders climb in the Boeing book.

Now for some important direct answers on the bullet points.

Yes, the A380 is in a pickle, because of its niche spot in the market, where it's reaching saturation, unless customers become more innovative for its equipment.

Yes, Qatar is playing the order clock and rethinking its positions and its airline strategy. Possibly many other airline companies are in the rethinking mode, as customer fickleness sets in. Better plans mean better profits is a common corporate model.

Qatar has sent Airbus a warning shot over the Airbus bow as is customary for this Airline. They are testing Airbus resolve for the A350, as well as buying time on the delivery clock. Money is not an issue, however, the Qatar fickle business is strong.

The pickle business is in that 10% slice of the market where the A380 lives.

The Most Sultry Woman In The World Is A 787-9

Etihad had its first airplane flown in test today. What's so stunning is not that its a 787 but a sultry beauty is unleashed. Sometime the subdued is more beautiful than the gregarious and ostentatious scheme. The Etihad paint scheme reflects the beauty of the desert. Something that achieves a relevant place in your heart as you look at the lines. Its how you wear the clothing that captures the heart. The Etihad 787 most import flight was not how she worked taking-off, but more importantly how she looked doing it. Simply elegant!

After looking at this first test flight photo of the 787-9 and trying out my observational critque, I grew to love the subtile paint scheme. It spoke of hot desert nights with a cool light reflecting on its body. Simply sultry and captivating. No flash, but a soft glow of what Etihad tries to emulate with its company colors.

How does the its 787-9 look in the rain's high gloss? It's simple to see it's the "Best of the Paine Field Show" , is Etihad's paint scheme.

Selling Furniture is Divergent to Selling Airplanes

Customer/Builder Divergence

When making a presentation to corporate heads, it is best understanding the audience. Better than the audience knows itself. If you don’t, you lose the audience in a divergence. They, the audience just doesn’t get it. Parry this down to the Board Room level, with a marketing representative, the presenter, who must become a chameleon in the room. They must understand the divergent dichotomy of decision making from the selling company as compared to the buying company. 

A sales person has a lot riding on its effort for those thousands of workers back at the factory. I know this on a small scale as I was owner and sales rep for the small factory of workers back home. I needed to keep their jobs intact, pay the materials bill, and meet payroll in one road trip.
Not only was I involved in the many-hats-I-wear division, I designed the product with the work force made advertising, and cold calls over a seven western states region. On and on went the duties for this small endeavor. It’s not much different than what Boeing does for its $$billions, as I was dealing with thousands of dollars.

·       The first task is to find out what does a customer want, not what you have for them.
·       The second task is understand a customer’s vision and how they see themselves obtaining its goals and objectives. Not thinking what’s printed on the company’s flyer for a mission statement.
·       Talk about dreams, aspirations and failures.
·       Know your enemy (Competitors) better than the enemy knows itself.

Once you have established a relationship and common knowledge you are almost ready to start sales. I never hurried the relationship part, as a bond must form first, and a trust evolves during short exchanges on ideas and opinions. I generally morphed into the person I wanted to sell to not out of some kind of patronizing effort, but out of the necessity of knowing your customers heart. I remember one time going to a customer on a cold call, driving through western United States. I think it was Idaho Falls, Idaho. I was 350 miles from my home shop. Nothing had happened on this trip. I was enthusiastic about the product, I had a stake in it, and I didn’t even know the next person I was going to tell about it!

So I pull up to this fancy store because it had space to park my truck and trailer. My trailer contained samples and furniture to sell. Not airplanes, but furniture. Walking into the store, I hunted down the person in charge of buying. No letter of introduction, no prior conversation and no appointment. So I told him like it was straight up, and then broke the Ice with asking him how it was going for him? We got it going by not talking furniture product. I told him how many places I had gone to this week, and people I had talked with. In particular to him were his competitors. He wanted to know what they were carrying in those stores. I told them everything they got came out of South Dakota. This also, was my main competitor in furniture making. They had a rail siding bringing in materials. I knew I only had this truck and it is nice truck, but I didn’t tell this man about how small we were. I only said they were our chief competitor, and we had made progress over what they did. He said, “Let me see”.

I went out to the trailer and set down a sample of each furniture type. By now we were on the same team slaying that same South Dakota monster furniture builder. We were no longer divergent, disparate or unalike. His problem now had become my problem. I was on to something, and I had a solution to both our problems. I had the high ground of a great product bonded with this company’s need to compete.

I then sold a hundred pieces that day and a hundred more each month because he blew them out of the store for a ridiculous low price, and still made money. Much like selling airline tickets flying with this furniture.

This story was repeated over and over again. I remember going from 100 production pieces a month to twelve hundred pieces a month in one year.


Boeing on a much grander scale has now obtained 1276 orders this year similar to what we built in a month. It was good stuff and people responded in spite of the South Dakota hype machine. I didn’t wear a tie, but I could tie a deal, because it was fun selling something that was so good.

Delta Order Playback

Delta recently ordered 25 A330 NEO and 25 A350-900's. Here are the three talking points for this order.


  • Time
  • Timing
  • Timeliness
There is a time when Delta is ready to move. That time is now, irrespective of where the Airplane builder has a slot or a position for its accommodation in time. The time is now for Delta to upgrade the fleet. Could Boeing answer the order bell? No they couldn't, as the 787 backlog swamp and the future 787-10 planes are way down the road considering Delta's time piece. Boeing can't meet Delta's corporate time-line.

The second point is timing for Delta. They need to receive these aircraft in a timing sequence, in order to fulfill its fleets expansion in a seamless motion.  It needs a whole new fleet improvement from latest technological aircraft that are efficient without waiting. The timing failure is from a Boeing order book predicament, which would swallow Delta with the cost of waiting on a long order book.  Airbus answered this question sufficiently, it could meet Delta's timing with A330's and the All New A350, where the 787-10 is not going to be ready until 2020. Delta could also reieve an A350-900's sooner than the 787-9. Left out of Delta's conversation is the 777X. This model also falls out of timing until 2020, even if Delta were first in line to receive one. A Delta 777X would be more likely arriving in 2024 than 2018 because of prior customer's build slots. A 787-10 is more likely in 2024 than 2018. That leaves Boeing timing for 2018 on the backs of the 787-9, which does not reach the broad spectrum of Delta expectations for 315 well placed passengers. The 787-9 could compete with what Delta wants, but thy have a backlog problem. The A350 is at 750+ orders and also has a backlog problem for Delta,  but has more flexibility within its order books, as the A350-800 and A350-1000 are not in play yet. They are planning a build-up on the A350-900 production during 2014-2018 where it will begin streaming aircraft towards Delta in 2018 with its A330 NEO followed by the A350-900 later.

Motley Fool Photo Credit

Delta sore card:


  • 787-9 wouldn't be delivered in Delta's window by 2018.
  • A330 Neo is a rebuild and upgrade project it can do, fitting in the Delta 2018 window.
  • 787-10 isn't even built or tested and won't be ready for Delta for six more years as it would wait behind 132 787-10 orders.
  • The A 350 is starting its delivery in days (December 13), and a delivery schedule has holes in it for Delta sliding in at a regular pace from 2018-2020, fitting its growth model. The 25 unit A350 production slots can be fit-in during 2018-2020 time frame at a rate of one a month.  
  • Boeing is booked-up as its own production schedule, when others have dropped or asked for delivery extensions. Even Delta has extended out its own 787's delivery schedule from its prior ordered 787 models and Boeing back filled those openings. Boeing couldn't promise more slots to Delta from other customera. Demonstrating how critical delivery is for Delta during a fleet renewal period it went with Airbus.


This brings us to the final talking point timeliness. Boeing is producing a balance of 787-8 and 787-9 in a simultaneous effort, appeasing its own customer thirst for the 787. The model is exceeding in spite of "787 glitching". Its far more complicated than what Airbus offers, and will continue its maturation for another thirty years. Having said that, Boeing is primed for an airplane sales explosion in 2015 and couldn't help Delta, even if Boeing's eyes were bigger than its stomach. Boeing will say anything to close the deal as would Airbus. But Delta looked at each company's position and decided that Airbus was less encumbered with order status, and therefore the likely hood of timeliness is more predominate with Airbus. This is built on several assumptions. One is that that Airbus will not endure any 787 like faults since it employs standing technology fully vetted for reliability. When Boeing reaches its final vetting process for its systems and battery. The 787 will be a great and greater airplane than what Airbus offers in "Time". Boeing's full 787 and 777X potential will then be reached, setting Airbus back decades in the race. I would expect Boeing will transfer "in-time", the "All Electrical Architecture" to its sibling aircraft, but not until all faults are resolved in the maturation process. Timeliness is a perception issue for Delta, more than an actual problem with Boeing. They see Boeing biting more off than they can chew with quantum leaps in technology and concurrently running projects. Delta views Airbus timeliness more achievable as it had taken the lower road for airplane progress. They have bet on Airbus timeliness with this order, which fits its own corporate goals.

Home work is a good assignment for readers. Below is a link of a fairly minded view on the Delta decision, and is not neccessarily a bad thing for Boeing. I recommend reading this article as it may shead more light on the subject, as it did for me.

Almost Missed This: Ryan Air Books 100 737 200C's with Boeing

Asleep at the order switch was I, as Ryan Air and Boeing booked the deal on November 28th which was announced as an intent, a little while back (September 2014), saying they would sign when enough cash is printed. What lies beneath this order was not mentioned in the below link, as this is a new class 737 holding 197 seats for Ryan Air. It has an additional door, less kitchen amenities but keeps the Max efficiencies. This aircraft is designed as a Ryan Air passenger work horse. 100 options on this order were added per further news reporting.

"Boeing capped the month with the Nov. 28 finalization of Ryanair’s order for 100 737 MAX200s (valued at $11 billion at current list prices). Bookings logged earlier in the month included 80 737 MAX 8s for SMBC Aviation Capital (valued at over $8.5 billion at current list prices); six 737 MAXs (variant undetermined) to an unidentified customer; four 737-700s (valued at $313.2 million at current prices) to an unidentified customer; 30 737 MAXs (variant undetermined) to a third unidentified customer; and a 787-9 Dreamliner (valued at $257.1 million at current list prices) to Virgin Atlantic."

However, 737-200C options are mentioned on this link below:

Options are reported in Link:

From, Aero Space Manufacturing and Design:

"Dublin, Ireland –Boeing and Ryanair have finalized an order for 100 737 MAX 200s, valued at $11 billion at current list prices. The order, originally announced as a commitment in September, includes options for 100 additional 737 MAX 200 airplanes, and makes the Irish low-cost carrier the launch customer for the newest member of the 737 MAX family of airplanes."

Other airlines are measuring Ryan Air's metrics on this configuration, and I believe competitors will follow suit for its higher density single aisle routes. I would expect conversions from prior orders over to the 737-200C Max and addtional new orders for this configuration.

Li-Ion Battery 101 From The NTSB.

The battery simplified. In order to not oversimplify Boeing’s  battery with the National Transportation Safety Board (NTSB) determination regarding its battery fires, and mishaps, it is an attempt to lay out what went wrong during 2013 and what the state of the Boeing battery is today. I have in other blogs attempted an objective understanding of battery woes, particularly the Lithium-ION monster that grounded Boeing. Since they are the world’s largest airplane maker in sales and production at this time, Boeing bet the bank on its LI battery problem. They willed a resolution from its failure. The NTSB came back and pointed fingers at the Battery manufacturer GS Yuasa, FAA, and Boeing.
I have learned several things of importance from the NTSB.

1.       At the time of testing and development the NTSB was not involved and could not help.

2.       FAA was well out of its technical scope giving oversight to both Boeing and GS Yuasa.

3.       FAA deferred from its own battery technology weakness, to both GS Yuasa and Boeing when they in return presented to the FAA engineering solutions. FAA did not have the expertise to give oversight.

4.       In this gap of expertise for both Boeing and FAA they deferred to the battery manufacturer when that manufacturer had never before built an airline battery of this stature until the 787.

5.       A cascading event leading to the battery failure was about to expose the depth of everyone involved knowledge, and its understanding of battery failure concerning a mitigation process for inherent risks. The NTSB has the high ground in this case, and they have spoken even though Boeing has installed battery safety through measures enumerated in 2013.

Below is a flow for resolving battery risk without knowing a precise moment of failure and its cascading consequences.

GS Yuasa did not meet a high enough standard of battery production, consistent to aviation risks. Impurities were allowed-in or missed during processing this battery’s substrate. Faults and flaws within the battery would lead to failure eventually. They have currently upped its aviation battery standards since 2013. Aviation LI-ION batteries now follow a tight standard and production protocol mitigating any impurities previously found in the battery.
:
The “Boeing Safe Battery system” is safer than any electronics battery found on equipment today.
:
Boeing engineering set voltage regulation too high at first, when sending electricity from its generators.  The Boeing problem: inputs electrical flow into the battery having a wide range of voltage spikes, beyond what would be safe, for a vulnerable battery not aware of  “shorting worthy impurities”. It was a big unaware of risk for Boeing during early testing and commercial service. Boeing has seen to it by narrowing and regulating the voltage spikes coming into the battery, which makes it safe for the battery, and will not cause shorting found within a battery impure substrates.

Boeing doubled down by encasing the battery with a stainless steel housing. It robs the battery encasement from oxygen, therefore no fire potential just battery heating. Further it vents the battery encasement by going outside the airplane where any toxic gases produced during a battery crises is dumped safely from the crew and passengers. Boeing presented a worst case scenario to both the FAA and NTSB, demonstrating a total battery pack failure, fire, or explosion. Showing it completely contained at all times. Plane flies on until safely landing. Only the airline deals with the mishap not the passengers during flight.  
:

The NTSB is concurring with what both GS Yuasa, battery maker, and Boeing on product saftey, while pointing its finger on Boeing and GS Yuasa for its failures. Both were out there winging it with battery technology without having federal governance (FAA) who was or is incapable of giving oversight with this technology. It is an emerging technology, where no one has gained an “arms around it” mastery. Boeing has corralled it in a safe area good enough for extremely safe flying for its customers. The good news is that aviation is using the Li-ion battery in its current evolution which will spur on further and complete mastery over battery development. On my first DC-3 ride, I remember watching sparks coming out the engine cowling, like we were on fire. We were flying over the continental divide. I felt I was in a “Lost Horizon” movie going into Tibet. It was winter and it was snowing, but the sparks have been long replaced by the likes of the 737, 777 and 787.
