Southshore Posted June 2, 2003 Share Posted June 2, 2003 The blended winglets that I think WJ is looking ar are not a Boeing product - they are licenced from somebody else by Boeing. the KFC winglets are altogether different. The blended winglets are quite a bit more efficient but they are kind of heavy and you have to weigh the cost against the return - they are expensive. Hauling them around on short haul - hmm, I don't know but, on longer legs they probably pay off. Ask Stu. I'm definitely an apologist for WJ but you gotta compare apple to apples. cheers Link to comment Share on other sites More sharing options...

Guest quietwing Posted June 3, 2003 Share Posted June 3, 2003 The winglets at KFC are a part of a noise reduction program to make the aircraft Stage III noise compliant. Link to comment Share on other sites More sharing options...
Guest saymach# Posted June 3, 2003 Share Posted June 3, 2003 "The winglets at KFC are a part of a noise reduction program to make the aircraft Stage III noise compliant" Correct Sir; but if memeory serves correctly, as an added feature they provide about 0.5% fuel savings as well. Which on the 72 is nothing to sneeze at Link to comment Share on other sites More sharing options...
Guest Snowshoes Posted June 3, 2003 Share Posted June 3, 2003 Saymach#, I used to fly Royal's 727 C-FRYS which was equipped with Valsan winglets. But along that mod came a rerigging of the inboard flaps which entailed a few additional degrees of extension even in clean config. These mods produced shorter time to cruise altitude and less induced drag thereby reduced average fuel flow. Are KFC 727s' inboard flaps modified as well? (If there is a restriction of not using flaps 40, than they are). Just curious... Snowshoes Link to comment Share on other sites More sharing options...
Guest quietwing Posted June 3, 2003 Share Posted June 3, 2003 I believe the winglets at KFC are from Dugan Air. The inboard flaps are permanently drooped 2-3 degrees. If I remember correctly normal landing flap was 25 degrees which increased your chances of a greaser. There is a restriction not to use flaps 40 unless required for an emergency.
