superspotter,
Not a wind up. According to our latest Boeing Newsletter "We (First Choice Airways) are looking at being the launch customer for winglets on the 757. We have an available airframe which could be used for first type trials in the USA. The winglets are the same size as on the B737NG (2.5m high) and weigh about 650kgs. Obviously they reduce drag and thus improve fuel consumption. The fuel savings are in the order of 4% and increase with sector length. Still much discussion here, but we are seriously looking at this proposal. We will also look at winglets for the 767 but we will not be in a position to have them fitted prior to summer 2005. This is an interesting idea but of course the fuel savings are all computer generated at present. There will be no hard evidence until airframe trials are conducted."
Personally I would rather they concentrate on addressing the crewing levels and low morale in the Company but that's another thread altogether.
