DO winglets have effect on Vref when landing?

JLS,

Thanks, will look at the thread.

I know the 737 series with winglets is really slick compared to the ones prior. I would guess that the reduced drag near te ends of the wings and improved airflow from the sharklets, that the A320 would have similar features.

In the training, is this something the pilots are made aware of, the increased speeds, and issues with energy management on final?
