JAF B767 Winglets - Why aren't they there ??

[cathay belgium]

Hi,

As in title, why aren't they there right now, even after OO-TUC's D-check since
they supposed to reduce fuel consumption??
As I flown JAP & TUC last week for my holiday I noticed the B767 of Neos/Italy are already
equipped with winglets..
(& it looks also better )
And as the Neos B767 has also flown for one season by JAF I was wondering,why ?

Is the positive fuel-consumption not worth the investment or just bad management?

If anyone has the answer of have arguments/ideas in a + or - way please leave comment!

( could have been the same for SN737-400 but since they're planned to leave the fleet... ,
anyway the fuelconsumption would be + for Korongo also .., but I don't think the 767 of JAF
are gonna leave the fleet soon (new ? interior -already duct-taped conf. TUC- )
and the 787 delays .. )

its not like you can just order a pair of winglets and put it on.
other factors to notice : - a lot of airlines are trying to retrofit the 757 and 767's but only one or 2 company's have rights to perform them
- winglets increase width by 3m and have each a weight of about 750kg
- saves about 5% max on fuel

Dear Cathay Belgium,

If life was so simple, I guess we'd all know it... It's not a question of "are they not interested in reducing fuel consumption?" (of course they are!) or "bad management" (think of the success of Jetairfly?). Someone at Jetairfly is a kind of "fuel manager" and makes lots of studies about all these concerns, and one of these studies is about the B767 & its winglets.

Do you think it is that simple to have winglets equipped like that? They cost a lot, you need to ground the aircraft for a couple of days, you need to do test flights, and for that they need to be worth it...! The B787 is supposed to arrive in 2013 (initially early 2013...), it goes quick...

It's a bit more complicated than "put them on and wait and see..."

Kind regards

Dear JAF737,

It's a bit more complicated than "put them on and wait and see..."

Maybe my question was put in a wrong style, was just wondering why aren't they there yet ?
Exactly!

If the equipment and the test-flights and grounding the aircraft are to expensive , the answer is easy.
NO, to expensive,not worth the money.

In that case, why did a familiar company like Neos ( JAF Italia ) and Thomson (JAF ENGLAND ) DO
optioned to place them.

5% fuel reduction isn't maybe not much today but don't forget fuel rates 2 years ago..
Time goes fast.
Same could be said for the 787 ( and his delays, yet another delay is mentioned few days ago.. )and
I heard there's only one option for a 787 for JAF and with the ( fantastic ! ) routings of JAF they need
more as 1 !
So the 767 ( JAP I suppose ) do need a longer life-time than 3/4 years I guess !

Pity you tought that my question was that simple. Wasn't meant to do so..
I'm quite positive of JAF and their management ( exc. their solution for TUC ),
flown it the last 6 years each summer.
( yes,ex. 1 year each year TUC and really didn't see much improvement this year ! )

cnc - only 2 companies ...

These companies must be having a filled order-book then ..
or why not?

So, winglets ..just a hype then ... or only worth the moneyif equipped from delivery as B737-800 and the new A320's in the future..

it is worth it! even if they keep them only for 2 more years
btw JAF equipped OO-JAN with winglets after they got the a/c
and like JAF737 said its a lot of work, reinforcing the wings, test flights, ...

Besides a 5% fuel reduction (with attendant range increase), the winglets allow for lower engine throttle settings that result in lower emissions. I noted that the winglets had not been fitted to the test AC, and assume that they will be fitted before delivery.

I'm also guessing that a retrofitted B767 has a higher residual value than a non-retrofitted B767...but as mentionned earlier by others: there are some really serious people who analyse this on a daily basis, so it's not that straightforward. I also think whether an airplane is fitted with winglets or not cannot be wrapped up in 1 or 2 reasons. Given the complexity, explaining the decision would probably require multiple reports.

By the way, "just" 5% fuel savings?! Even 1% fuel savings is huge for a fleet of only 2 B767's that virtually fly every day, knowing that they burn around 30 tons a day.

they also reduce noise pollution.
airports should do something to encourage airlines to retrofit planes with winglets if possible

[ostend_airport]

The reason why JAF does not install winglets on there B767 is because hangar 4 (tec4jets hangar) is too small. I think (these are my words) JAF, Tec4jets and BIAC are looking for a solution.
