"steve.t" wrote in message oups.com... Jim: I've noticed and have flown C-15x with the exagerated wing tip (folded down) and I've not really noticed any improvement at low speed (which is what I think it is for, better handling at low speed for approach). What I am interested in is increased lift, and better performance (in terms of fuel usage) which is what the winglets do for the B-747 (something like 30% improvement in fuel economy! if memory serves me correctly). Oh, no, not 30%! If that were true then every plane would have them. http://www.boeing.com/commercial/737...ets/wing2.html |
