Winglets,those bits on the end of a aeroplane wing !

They prevent, or more accurately reduce, wingtip vortices which can cause high amounts of drag and also turbulence for following aircract.
High amounts of drag at the wingtips can lead to tip stalling.

I watched a discovery program about them, they are a revelation to the airline industry. They reduce fuel consumption, and prevent the ends of the wings vibrating (?) by dispelling the vortices up and away from the main wing. Or something like that. All in all it aids safety, fuel usage and wear.

The reduced fuel consumption is more of a side-effect from the reduced drag. They were introduced mainly to prevent tip-stall, a direct consequence of which can be either a spiral dive or a full on spin.

They used to be how you told a 747-400 from earlier jumbos; I think they were the first aircraft to be fitted? Sad anorak alert

You are all wrong. They are the small bits of plastic left when you detach the sections from the plastic frame after you take it out of the box and before you assemble the plane. You can buy small files from Model Zone that take these off or just ask your mum if she has a grade 4 nail file. It really does ruin the overall look of the finished model in my opinion and is just plain lazy. if a job's worth doing....
... since by dispelling the vortices at the wing tips more of the wing produces lift making it more efficient. Hence a bigger plane needs smaller wings.
Very good, but how can you tell the difference between a 743 and a 742?They used to be how you told a 747-400 from earlier jumbos; I think they were the first aircraft to be fitted? Sad anorak alert

743 was the first to have the extended top deck? I think Singapore Airlines introduced it. Big Top/Megatop?
Well done sir and anorak like myself, did you enjoy the first flight of the 787?Yes, that is of course my exact reasoning...

Bit delayed, wasn't it? Have you had the privilege of flying on the 380 yet? I have, only trouble was I couldn't take the Singapore Airlines hostie who served me home
Not yet, which class/cabin did you fly in? Hoping to try AF's 380 CDG-JFK next year one way and on the way back JFK-LCY on BA's baby bus.Bit delayed, wasn't it?

also the seat config was different. also do you know the difference between the 747-100 & 200's?
Is it that the 741's only had six windows in the buble (3 each side) the742's had 10 windows?

correct answer, Virgin used to own the 10th off the boeing production line G-VMIA

i have the ownership plate @ home as i worked for them at the time
Did VA use to have a lounge in the buble like Pan?
