Winglets

Hi,

I've just installed PMDG's 737NG and I notice that the models come with a winglet or no winglet version. I know what winglets are, they're the little piece at the end of the tail that point up (although I'm not sure what exactly they do) but in real life don't all planes have them? Therefore why give the option of not having them in the sim?

Also, I notice some liveries that I downloaded, like the Ryanair 737-700, come with a stairs. This sounds really cool, but how do I get a stairs to come up to the plane when I'm on the ground. What do I have to press? And do you see the stairs driving up from the terminal or does it just appear?

Thanks a lot in advance, JTH 🙂

I think actually that the winglets are like little tiny tails on each end of the wing. picture:
Look at the end of the wings. they have those little 'winglets'. and no, not all aircraft have them.

They produce less vortex drag, decrease a planes chance of stalling at certain speeds when turning and of course they can store lots of extra fuel.

Robbier is correct. Winglets have nothing to do with the tail. They are angled extensions of the wing on some aircraft and their purpose is to reduce wing vortex (the tornado-like spiral of air coming off the end of the wing) to increase lift. See http://www.airandspacemagazine.com/ASM/Mag/Index/2001/AS/htww.html for a more detailed explanation.

I'm not sure what you were talking about when you said "little piece at the end of the tail that point up". The only thing I can think of you might be referring to is the vertical stabilizer, however, on most aircraft that is not particularly little.

Sorry I meant to say "wing" where I said "tail", I don't know what I was thinking!

Anyway, thanks for all the info. But if winglets are this good, and they don't exactly look hugely complex to install, why do not all airplanes have them? Also, why would the 737 be offered with or without winglets - would this happen in real life?

Thanks again.

Also, does anyone know how to get the stairs?

To fit winglets on some a/c would not be economical - weight, size, general usage of a/c etc..

I know you haven't asked about the exits/doors yet... but you will Yes

Okay, thanks. So when Boeing ship 737s etc do they offer them with or without winglets?
