Hi guys,For a reason i am not so sure of, SAS have a lot of thier 737 NG's without winglets.. personally i think it looks very nice, i think i prefer them to none winglets,In your opinion, which do you prefere the look of?go on airliners . net and put this after the net photo/Scandinavian-Airlines--/Boeing-737-883/0988435/L/&sid=eae04e51587912ed5a8565d0230bbee6

Older model i suppose.Personally I prefare winglets / fences, they make planes lookmore modern and sleek...

When you read the official stuff from Boeing on winglets for the 737, it includes a nice list of statistical data on fuel burn, efficency, higher ceiling at MaxTow. And then at the end there they add in that winglets give your airline a modern look and feel to your passengers. Piece of mind thing I guess.I prefer the winglets on the 737, they are incredibly uniqure, nothing looks like that. It is just aesthetically pleasing in my opinion.

Agreed, the winglets really make the plane look complete. I remember the first time I saw it. I used to live in the Netherlands close to EHAM and so often had approaching aircraft above me when driving past the airport. I was at first thinking it was some new aircraft that I hadn't heard about, but then realized it was a pimped 737 :-)I will surely have the winglets option on when the NGX comes out.

On airliners I don't mind either way myself, although on the smaller aircraft I fly, winglets have been around a long time, and I have a bit of a love/hate relationship with them, because I like the efficiency but dislike the way they make things more fragile and awkward when ground handling.Incidentally, there are a few reasons why SAS might have some 737s without the winglets and some with them. In the first place, winglets are not cheap to buy or install either from new or as a retrofit, so an aircraft typically has to be one that the airline is intending to keep and use for long enough to make the investment cost of adding winglets worth paying for. Ensuring winglets are an economical proposition depends on how the aircraft it used: Winglets are heavy, on the climb to cruise they are to a large degree dead weight, since their shape is optimised for the longest phase of the flight (i.e. the high speed cruise in thinner air). For an average 737, the cruise would be between about 800 and 1,500 miles depending on the model, and for something like that, winglets are an economical proposition, but on something like a domestic inter-city shuttle flight, where the aircraft barely even has a cruise phase, having winglets just means hauling some extra (and very expensive) weight up to 21,000 feet.So for some airliners it makes sense to have winglets and for others it just isn't economical to put them on there considering the cost of them versus the savings you'd make. Some of it is pure aesthetics, i.e. to make your airline appear modern to your passengers, but most of it is economics.Al

I prefer winglets too. It makes a plane look complete, and more sleek.Maybe they can do what Captain Sim did. When I go to my CS757's Load Manager, I'm allowed to choose whether I want my 757 to have, or not to have winglets. Cheers,

@CHOCKthat makes perfect sence, thank you very much for your input!I know that SAS sometimes do very short hops, sometimes only lasting 30mins, and a lot of these, so your explination makes sence:)

NGs without winglets look extremely strange to me - put me down for the with winglets version!

Winglets for me!

I'm a winglet kind of guy. Although it's taking some getting used to seeing 767's retrofitted with them.

Nope - Easy one for me. Hate them!

Winglets for me too :)I wonder the price difference.. i have heard that boeing has said in the long run it is worth the extra money up front... anyone know how much more?

Its somewhere around $850k.

Winglets for the NGs apparently cost about 750,000 Dollars, but you can add an extra hundred grand to the price tag to have them retrofitted. So that's nearly a million bucks if adding them after purchase, whereas their fitting is incorporated into normal production if you order them from new. It takes a few days to retrofit them, so a 737 will be out of service for about a week if getting them retrofitted as they don't simply bolt onto the ends of the wings, and there is also the additional cost of your 737 not earning any money whilst having them fitted, plus it having to transit to a factory to have the work done.There are some system alterations necessary to retrofit winglets (since they alter take off, climb and descent performance, so the FMC software has to be altered amongst other things), and they also require some internal strengthening of the wing and centre section to be added in order to support the weight and in-flight forces the winglets generate. Overall, the addition of winglets and the strengthening necessary to support them adds a shade under 500lbs to the weight of a 737, which doesn't sound like a lot, but it's the equivalent of three more passengers or a bit less fuel if you look at it the other way.If all that sounds like a pain in the &@($*, it is worth bearing in mind that they do mean you can take off in a shorter distance for the same weight as a 737 without the winglets, or go for the same distance take off roll but with a higher ramp weight. They do save some fuel of course and they increase climb performance as well as reducing noise a tiny bit too. Theoretically they also make your engines and airframe last longer as well, since with a faster climb, you spend less time at high throttle settings, which reduces stress on things.You can get winglets for earlier 737 variants too incidentally, but they are made by a different company and don't look the same as the ones on the NG and are instead more like the smaller kind you normally see on an A320 except without the downward pointing fin. Dunno how much they cost offhand, although I do recall an article in Airliner World about the Quiet Wing Corporation (which is the company that makes them) and I remember that they weren't cheap either.Al

Is there at least a single flying 737-600 with winglets? I don't think so.
