Nice steep take off!

@HamburgAirport Yes it was a steep take-off. The advantage of a short-haul flight operated by a long-haul aircraft. Not weighed down full of fuel so essentially quite light so you can get going!

@xXmand123Xx That's quite a big one to answer quickly, but essentially they reduce induced drag. So by reducing that drag you save fuel. Maybe 4-5% on a standard flight. Which then means you can also increase your overall payload as you are using less fuel versus an aircraft without winglets, so another benefit. Boeing gives a good description on their website.

@AirNewZealandUK Ok.. thanks.. Kinda makes no sense really... not you personally but boeing/in general.... Less drag, well theres more on the wing so really it should create more drag... im not saying anything against you, just in general it makes NO SENSE! lol thanks for the reply !

@xXmand123Xx I hear what you say. It is a bit hard to get your thoughts around this one, but the winglets do work. And it's not just Boeing. Most manufacturers have some sort of winglet on at least part of their fleet. Airbus, Bombardier, Beech etc. Air New Zealand is the launch customers for the Airbus 'Sharklets' on the newly delivered A320's from 2012. And many other carriers are retrofitting winglets of some sort to their existing Boeing fleets i.e. Southwest, American etc.

They sure do! Sadly, I was quite fixated with them the whole flight. It was sunny all the way and the way the sun highlighted the paint job was awesome. So they look good and save fuel!

@AirNewZealandUK Airbus basically copied Boeing and just called the winglets sharklets. It has nothing to do with sharks.

bro its just a good video stop trying to sound like you know it all.

@xXmand123Xx On a wing without winglets, at the tip the airflow is disturbed due to the material "ending" so to speak - that is, there's no further wing to channel the air. Winglets provide a medium for the air to be streamlined against, giving a cleaner airflow over the top. This is increases lift. Although the winglets increase the wing area (drag) they also increase its efficiency

the bit from 15-18 seconds looks great when the sun strikes the edge of the wing
