This thesis presents a cognitive analysis of a pilots navigation task, and using this foundation, describes an experiment comparing a new map display, employing the principal of visual momentum, to the two traditional track-up and north-up approaches. The visual momentum display is based on the characterization of the pilots navigation task as the maintenance of a cognitive link between two reference frames RFs -- the ego-centered reference frame ERF an the world-centered reference frame WRF. The ERF corresponds to the pilots forward view of the world and the WRF corresponds to a north-up geographic map. The new map display employs visual momentum by presenting the ERF, in the form of a perceptual wedge, in the context of a north-up maps WRF. An experiment was conducted to assess the different displays using licensed pilots to perform diverse navigation tasks in the context of computer simulated helicopter missions. As predicted, the data showed the advantage to a track-up map is its congruence with the ERF however, the development of survey knowledge is hindered by the inconsistency of the rotating display.
