Was curious to know if this plane will wear any sort of specialty scheme or the regular Airbus colors? Hopefully this is the first of many more new Airbus aircraft that will wear the new "Sharklets".

Well don't flight tests have to be done? I would think that they would keep the wingtip fences on to do the pre-delivery tests and by then hopefully the sharklets will be certified and you can then unveil this plane with them on. At least, that's how it works in my head.

Airbus definitely wants accurate fuel burn information on the aircraft in the before and after configuration. What if the aircraft had an undiscovered wing warp or engine defect that increased the fuel burn by 1%? They would be selling winglets to customers with that error in performance.
The converse could also be true. What if the fuel metering equipment was off in measuring the fuel flow rate? By benchmarking a 'known,' Airbus can be certain of the improvements the sharklets provide.

Manufacturers don't like to build aircraft that are non-conforming. If they built the A320 without tip fences, it would not conform to the master drawing list for the aircraft and thus would not be type-conforming. To get a certificate of airworthiness, it would require an individual airworthiness certificate, which would be a hassle. It is far easier to build it to the type certificate, put it on the experimental register after delivery (to Airbus) and then modify it. When they are done testing it, they can de-mod it and return it to normal airworthiness.

I must say I'll be disappointed when the Airbus wingtip fences go away. They're my favorite design element on the A320 family...such a graceful look IMO.

Yes but they've been doing back-to-back tests with sharklets&fences on MSN1 since late last year, you'd think they have enough data by now...

This seems like the more plausible explanation. As that is a serial aircraft that will end up going to ANZ, and the sharklets aren't certified yet, Airbus likely has to build it to serial specs first, then modify it after its "delivery" to the flight test department.

I don't believe the aircraft in the photo (msn 5098) is for Air NZ as it has CFM engines and Air NZ has IAE engines.
It's possible Air NZ has cancelled the sharklets as there has been talk of them using the remaining 320's on order for domestic routes instead of the original intention of regional routes. Sharklets on domestic sectors would probably have no benefit.
Can anyone confirm who is getting msn 5098, nothing yet on planespotters.

Good remark, I hadn't noticed. But if this is the first sharklet a/c and ANZ is (was...?) the launch customer, something is wrong here. Who was the next customer in line for sharklets after ANZ? Perhaps a CFM airline...?

Does the A318 get sharklets as well?

I definitely agree with that, I too like the wingtip fence design element in the A320 family, but hey, at least the A380 still has them so it's not all that bad.

If they only have data from one single frame, I'd say they don't have nearly enough data. If you run a basic set of fence vs winglet measurements on a second, new-build frame and the numbers basically agree, then fine. If they don't, there's some engineering to do. You need a set of measurements against fences vs winglets on at least one more frame to be able to make performance guarantees that you won't regret later.

In comparison to the newer B787 fleet, one would only imagine that there are numerous differences between MSN1 and a current new build!?!? Correct? I don't see how they can predict firm numbers from a ship that does not comply with current build standards.

Since all aircraft aren't created equal, it certainly makes sense to test fences vs. sharklets on multiple aircraft to ensure the numbers "jive..."
The more data points, the more accurate Airbus can be with the benefits (or lack there of) that sharklets will provide.

Can sharklets be replaced with the standard wingfences? Perhaps they want to evaluate the wingfences with the new wingtip reinforcement structure as well?

As Spacepope noted, the reinforcements will change the performance. Or will it?
Did they need the reinforcements to do 'lost sharklet' testing? (All wing treatment devices cannot be fracture or safety critical. In other words, you must be able to fly with one lost. It wouldn't surprise me if Airbus chose to skip that testing until the wing reinforcements were complete.)

There is also most airframe to airframe or engine to engine variation than anyone wants to discuss. It is also a matter of instrumentation accuracy. In fact, for the level of improvement Airbus is aiming for, statistics implies they need to test 3 airframes to have any meaningful data. They should also test the A319 and A321. While I see zero reason the body length would effect the winglets, it would be risky to guarantee without testing the various A320 body lengths.
In the case of the A320/A321, it is going to be crucial to understand the benefits for MTOW long range missions. (TCON). But Airbus also needs to know the 2300nm mission (US inland hub to far coast), 1200nm (eastern seaboard, long range), and of course shorter missions.

Yes, It's been mentioned numerous times that this will be the final time that MSN1 will be used as a testbed and in fact will be retired following these "Sharklet" tests.

So they wouldn't need to install the fences if they didn't have to, instead just install a standard wingtip.
There is a very rigid process, put into place by law, as to how an airplane is configured it is to be certified as airworthy.
If Airbus wanted to build the aircraft as conforming to the A320-100, with no tip fences, it would be limited to a max take-off weight of 149,940 lbs and would have to be powered by CFM56-5A1 or CFM56-5A1/F engines (see the TCDS). Once built as a A320-100, it would be extremely hard, if not impossible, to convert it to a A320-200 and thus would be an unsellable orphan.

Quoting gigneil (Reply 1): Why doesn't it just not have wingtip fences at all right now, I do wonder.
But it does have the wing tips fences on. They are just visually blending into the background grey area where the numbers are painted.
