Question about wings on Continental Airlines plane?
I hadn't flown in 7 yrs until last week when i went on a vacation. My
question is that the plane i flew in had the tips of its wings bent or inverted upward. I had never seen this before. Someone told me that this was done to save fuel, but is that it? |

Someone told me that this was done to save fuel, but is that it? The winglets you saw create the effect of greater wingspan. This increases the apparent aspect ratio of the wing which makes it more efficient. So, yes; it's done to save fuel. -- Dan C172RG at BFM |

From http://oea.larc.nasa.gov/PAIS/Concept2Reality/winglets.html: "The resulting reduction in aircraft drag for a properly designed winglet configuration can be extremely significant in terms of fuel consumption and range." -- John T http://sage1solutions.com/blogs/TknoFlyer Reduce spam.
