    Burki-Cohen, Judith S. ;
    Sparko, Andrea L.
    2007-08-20 | PDF
    In this paper, we first explain that pilots experience airplane motion via multiple perceptual systems, which makes motion a candidate for simulation via stimulation of only a subset of these systems. Next, we discuss the relative merit of vestibular cues when piloting an airplane. This is followed by a comparison of the vestibular cues received in ...

    Soares, Melanie A.
    2007-06-30 | DOC
    In July 1996, a new wake vortex category was created for the B757-200 which placed it between revised Large and Heavy categories. Shortly thereafter, the B757-300, stretched version of the B757-200, was placed in service and soon treated by Air Traffic Control as a Heavy aircraft due to its maximum certificated takeoff weight. This study examines t ...
