A300 Winglets Or Not...

Why does this aircraft not have winglets? When did AI start putting the winglets on the A300? Is it an option?

I don't know the full history of the A300 so some background would be helpful.

The A300-B4's (your picture) have no winglets.

The A300-600's have winglets.

The A310-200 have no winglets.

The A310-300 have winglets.
You're only as good as your last departure.

FDXmech,

Hapag-Lloyd A310-200s have been modified with winglets a few years ago.

Also for China Northwest (now China Eastern), one (B-2303) of their A310-200s is equipped with winglets.

One small note, they are not winglets, they are wing tip fences.

The only airbus with winglets are the A340 & A330

Am I correct in assuming that it's called winglets when the entire end of the wing is "curved up", and wingtip fences when it's only a small part (or something like that)?

A "fence" extends both up and down, as you can see here:

I assume that the downward extensions also play an important role, since modern aircraft with wing-mounted engines do not have fences, but pylons that do what the fences would do. Again, I'm certainly not an expert at aerodynamics.

By the way, I've always been wondering if this is an exotically-shaped winglet or a wing tip fence:

Anyone?

EDIT: reading the question once more, I just noticed that I might be wrong. However, my guess is that a winglet curves up (only), but a wing tip fence curves up and down, while it doesn't matter if it covers the entire length of the wing tip.

Don't cry because it's over, smile because it happened.

The MD-11 is a winglet with a small fence.
