Rolls-Royce Trent 1000 on the Boeing 787 Dreamliner

Rolls-Royce Trent 1000 on the Boeing 787 Dreamliner

Last time I was visiting the Future of Flight I picked up a very interesting brochure about the Rolls-Royce Trent 1000 engine used on the Boeing 787 Dreamliner and wanted to share the top 10 most interesting things:

#1: At take-off the Boeing 787 Dreamliner’s two Trent 1000s will deliver thrust of 150,000 lbf, which is equivalent to the power of 1,500 cars.

#2 The engine sucks in 1.25 tons of air per second during take off (that’s about the volume of a racket ball court every second).

#3 The 112″ fan spins at over 2700 RPM with tip speeds over 900 mph, but the blades inside the engine spin at 13,500 RPM with tip speeds topping 1200 mph.

#4 Air passing through the engine is squeezed to more than 700 lb per sq inch, which is 50 times normal air pressure.

#5 The engine has about 30,000 individual components.

#6 The Boeing 787 will carry up to 270 passengers, which is equivalent to the economics of a typical car with four passengers. However, the 787 travels ten times faster.

#7 The Trent 1000 is expected to fly for 20,000 hours before its first overhaul. That’s about 11 million miles or 450 times around the world.

#8 The fuel in the engine combustion chamber burns at about 3632 deg F — the sun’s surface is about 9941 deg F.

#9 The force on a fan blade at take-off is about 100 tons. That is like hanging a freight train off each blade. The first generation of turbine blades had about 10 tons of force.

#10 A Boeing 787 at full power take off is 3dB quieter than a Boeing 767, even though it is 1/3 heavier. At the airport perimeter, the noise level would be equivalent to that of a waterfall.

Amy's family took this photo when flying from Shannon to Paris. When sending the photo, Dorothy (Amy's mom) points out the Aerlingas plane in the background, which was going to the same destination and cost 3-4 times.

Don’t worry folks. The blog is not going to turn just into talking about Ryanair, but recently I have received not just one, but two emails from Stephen McNamara with Ryanair and they have caused a lot of discussion on Twitter and the blogsphere [check out the BitterWallet.com opinion on the letters]. A lot of people have contacted me and commented about how crazy Ryanair can be, but I think they just would take it as a compliment. I haven’t had the opportunity to fly Ryanair, but my girlfriend Amy has been able to fly them quite a few times and I wanted to share her viewpoint:

Due to a study abroad experience, and later a work relocation for a family member, I’ve had the opportunity to travel a bit in Europe, flying on Ryanair about 15 times.

Ryanair has cheap tickets to various cities in Europe.  They have a great business model ’“ no question about that.  I think that anyone who is duly warned about the downsides of flying Ryanair and then complains about it is getting exactly what they deserve.  It’s a low-cost airline, and they don’t owe you anything.  If you want a first-class experience, go ahead and pay three times as much to fly another airline.  If your main concern is fast and cheap Point A to Point B service to another European city, then low-cost airlines like Ryanair or Wizz Air or easyJet or whoever is the cheapest that week will do just fine.

You should do your research whenever you plan a trip, that’s a given.  There a few things to consider if you’re deciding whether or not to fly a low-cost airline on your trip.  For ease of comparison, I’ll refer to the points that David and Stephen McNamara were debating about Ryanair.

#1: Customer service ’“ Low-cost airline staff are primarily concerned with efficiency.  You may be trading above-and-beyond friendliness for getting the plane off the ground in time.  I don’t exactly equate on-time arrivals with ’œcustomer service’ but it’s important to recognize that Ryanair has a good on-time arrivals record.  Ryanair doesn’t do connections, so being on-time is pretty critical if you’re hopping around.  I was only on two late flights, and only one was a little catastrophic for my vacation plans.  Did I go complain to Ryanair?  No way.  Did I expect them to pay for my 200 Euro cab ride because I missed my train?  No ’“ I knew exactly what I was getting into when I bought that cheap ticket.

#2: Charging for the little things ’“ Yeah, there are lots of fees that make that cheap fare go up (though probably still cheaper than a larger airline).  Here’s a list of Ryanair’s fees.  However, if you have no checked luggage, can find a promo fare with no check-in fee, don’t need snacks or drinks, don’t need priority boarding (which most families do) and have no sports equipment, musical instruments or baby stuff (including actual babies ’“ 20 Euros), you can avoid a lot of fees.  Think 22 year old backpackers.  This is their heaven.

#3: Flying to small airports ’“ Ever heard of Reus, Spain?  How about Beauvais, France?  That’s ’œBarcelona’ and ’œParis’ in low-cost airline speak.  Many (but not all) of the airports that low-cost airlines fly to are outside of the major city where your hotel probably is.  In this case, you’ll probably pay about 15 Euros to take a bus for 1-2 hours.  In Weeze, Germany, I believe the bus we took into Dusseldorf was also owned by Ryanair, which is pretty genius.  When flying from London to Dublin, I booked a flight from Stansted and it required a one-hour train ride from London, adding another 30 BPs to the overall cost of the flight.  It makes sense that flying to smaller airports keeps costs low ’“ and it’s usually not a big deal.  Just know how to get to the main city.

#4: Ryanair is popular ’“ Well, yeah ’“ Ryanair was kind of the pioneer in this market and their route coverage has just grown and grown.  After awhile I would just assume that Ryanair had a better/cheaper flight than its competitors.

#5: Charging to make reservations over the phone ’“ I never called to book flights (I’d go to internet cafes), so I didn’t experience that first-hand.  I guess their argument is that people who use the online booking shouldn’t absorb the cost of paying customer service representatives that answer the phones.  Use the internet, it’s 2010.

#6: Almost never giving refunds ’“ I would never have expected a refund from Ryanair.  They are pretty upfront about being a bare-bones airline, and I’m sure the other low-cost airlines are the same.  Also, if you don’t get a refund, you’re really not out that much money.

#7: People fly, in spite of their complaints ’“ For me, the positives (cheap, good schedule) outweighed the negatives (slight inconveniences, occasional fees, minimal customer service).  There is certainly something to be said for the ’œif you don’t like it, go somewhere else’ approach.  There were a couple of times I felt frustrated and declared that I would never fly a low-cost airline again, but that feeling only lasted until I got to a computer to try to book my next trip.

Low-cost airlines in Europe really are in a class of their own.  For most routes, it seems like they compete more with ground and sea travel than they really do with large, long-haul airlines.  I came to view the small airports like train stations ’“ lines aren’t too long and you don’t need to be there very early.

Basically, if any other airline could offer better customer service, fly to bigger airports, and still be cheap ’“ they’d run Ryanair out of business.  But it doesn’t look like that’s going to happen, so for now low-cost airlines like Ryanair are your only choice and they know it.  Consider yourself warned and make sure to do your research.

Don't worry, no birds were hurt in this photo.

Don't worry, no birds were hurt in this photo.

Recently a reader made a comment on an old blog asking why don’t airlines or manufactures just put screens over engines to prevent birds from flying into them. I thought this was an interesting enough question to answer in a new blog, since I have heard others ask this same thing.

Yes, birds might seem light, but any object going 300-600mph is going to cause some serious damage when making impact. The strength and amount of reinforcement needed to go over the opening of an engine nacelle would have to be quite intense. Even if the screen held up, the bird would be stuck on the screen, stopping air from going into the engine, still causing a problem. If the screen failed, it would be sucked into the engine causing even more damage.

It is also important for air to smoothly enter the engine to optimal performance. With a gate in front of the engine, it would cause the air to slow and become turbulent, making the engine less efficient.

Overall with the lack of efficiency, the difficulty to make it work, and the rarity of bird hits, it is just not feasible to put a screen in front of engines.

Ryanair Boeing 737

Ryanair Boeing 737

On Friday I posted an email I received from Ryanair. I very much enjoyed the email and the interaction with Stephen McNamara, Head of Communications with Ryanair.

In the comments of the blog, I was asked how I replied to his email. I thought about a long reply, but settled on just thanking him for connecting with me and that I have corrected my blog. I was kind of hoping he would read the post I made and oh boy did he!

Here is his (unedited) email I received on Friday morning:

Hi David

While I  contacted the Seattle pi I will not be keeping a line of communication open with your blog ’“ no disrespect but I simply don’t have the time (or resources) to correct the errors most bloggers come up with ’“ but as you said, you have never flown with Ryanair so perhaps you are unaware that:

1.      They provide sub-par customer service (and are almost proud of it) ’“ Wrong. Ryanair has the best on-time record, the least lost bags and the fewest cancelations of any major European airline.

2.      charge for everything ’“ Wrong.  Ryanair allows passenger to avoid paying for any of the services that are factored into the cost of high fare tickets, the average fare with Ryanair (which includes a 25KG baggage allowance) is just €32 ’“ compared to the next cheapest airline at €60.

3.      fly to smaller airports.  Wrong.  In some cases we do, but we also fly to many main airports (e.g. Berlin, Edinburgh, London and Madrid etc) and passengers, especially those who travel frequently realise that it is more comfortable and quicker to travel through smaller airports ’“ while it also allows for cheaper fares which passengers would walk over hot coals to get to.

4.      but are one of the most popular airlines in the world ’“ Wrong (but almost correct).  We are the world’s favourite airline per IATA statistics which show that Ryanair carried more international scheduled passengers than any other airline last year.

5.      They charge customers to call their customer service hotline ’“ Wrong.  We don’t have a customer service hotline; passengers can contact customer service in writing only.

6.      and are well known for almost never giving refunds. Wrong.  While our fights are non-refundable we do provide refunds in rare cases of weather related cancelation (per EU 261 legislation) and in cases where they are entitled to a refund of government taxes and charges.  However, if a passenger is looking for a refund because their cat/dog/grandmother is sick they are not entitled to one, and won’t get one ’“ per the Terms and Conditions they agreed to.

7.      Yet, they provide super low fares and passengers keep flying them. Correct ’“ almost, it should really say and an increasing number of passengers fly them ’“ Ryanair continues to grow thanks to our low fares while other airlines’ passenger numbers continue to collapse.

But I guess I can let you have that one – one out of seven ain’t bad ’“ for a blogger!

Ryanair does ’˜understand’ social media and that blogs are generally based on opinion (which is why we generally ignore them ’“ unless they appear somewhere like the Seattle PI).  Far be it from me to preach on new media but like good journalists good blogs should be balanced and at least factual ’“ if a blogger wants to blog about something by all means go ahead but if people are going to take the time to read a blog they should be confident that the blogger at least knows the facts and matches those facts with the entertainment value a blog provides.

Finally, re ’œI have updated my blog, but in my defense, major news organizations were covering this, like the BBC for example.’  Ryanair was contacted by the BBC and provided a statement which was carried in the piece and explained the situation ’“ this however did not make it into your blog ’“ which is why we contacted the Seattle PI ’“ bloggers can not just take a story that entertains them and omit the facts ’“ as you clearly did in this case.  Major news organisations provided balance, when you picked up the story from their sites you ignored that balance.

Regards

Stephen McNamara
Head of Communications

Ha! 1 out of 7 or about 14% right (according to Ryanair). Surprised I got the “Ryanair is one of the most popular airlines in the world” wrong.  How about the most famous Irish airline in the US or at least on my blog? Now most of the rebuttals are questionable and I know McNamara is doing his PR job to put the positive spin on his airline.

Like I have said, I have never flown them before, so not sure how to respond to these. For those of you who have flown them, care to add your opinion on his email?

TUIfly's Boeing 737-800 (D-AHFM) with Haribo gummy bear livery

TUIfly's Boeing 737-800 (D-AHFM) with Haribo gummy bear livery

What’s sweeter than a livery with gummy bears on it? Not too much.

TUIfly is Germany’s third largest airline and is headquartered in Langenhagen, Germany. The airline was founded in January 2007 as a cooperation between Hapag-Lloyd Flug and Hapag-Lloyd Express. TUIfly flies both scheduled and charter flights. They run a fleet of about 40 Boeing 737, most of which are Boeing 737-800’s.

Haribo is a large candy producer who is also based in Germany. They are best known for making gummy and jelly sweets.

And if blue is not your color, TUIfly also has a gold Haribo livery as well.
