Anderson defines induced drag as the drag created by the presence of downwash - which arguably is very much related to wingtip vortices. You can *visualize* the physical generation of induced drag by picturing the lift vector tilting backwards - again, according to Anderson. Probably both of you are right in a sense. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
