    Study abroad is a transformative life and learning opportunity that is thought to motivate student expectations of the university and cross-cultural travel experience. Few studies, however, ask students directly about what they desire to know prior to embarking on a study abroad sojourn. Here, we report on qualitative findings from an interest inventory of feedback given by university students who responded to a standardized worksheet designed to align student and teacher expectancies about the expectations and provisions of learning experiences. Categories were summarized according to fit and similarity with factors discussed in studies of intercultural awareness, pedagogical design, and study abroad assessment. The results showed that students generally“ wanted to know” deeper domain knowledge about their host culture (New Zealand) and expressed being motivated to obtain a broader understanding about demography with authentic experiences. Implications for study abroad program design and assessment are discussed

    Flight Investigation of a Normal-Acceleration Automatic Longitudinal Control System in a Fighter Airplane

    A flight investigation was made to obtain experimental information on the handling qualities of a normal-acceleration type of automatic longitudinal control system. The control system was installed in a subsonic fighter-type airplane. In hands-off (stick-free) flight the normal-acceleration control system attempted to regulate the normal acceleration to a constant value which is dependent on the automatic-control-system trim setting. In maneuvering flight a given pilot's stick deflection produced a proportional change in normal acceleration, the change in acceleration being independent of flight condition. A small side-located controller stick was used by the pilot to introduce signals into the automatic control system. In the flight program emphasis was placed on the acceleration-limiting capabilities of the control system. The handling qualities were investigated in maneuvers such as slow and rapid pull-ups and turns and also in flight operations such as cruising, stalls, landings, aerobatics, and air-to-air tracking. Good acceleration limiting was obtained with the normal-acceleration control system by limiting the magnitude of the input signal that the pilot could introduce into the control system. The same values of control-system gain settings could be used from an acceleration-limiting stand-point at both 10,000 and 30,000 feet for the complete speed range of the airplane. The response characteristics of the airplane-control system combination were also satisfactory at both high and low altitude with these same values of control-system gain setting. In the pilot's opinion, the normal-acceleration control system provided good stability and control characteristics in flight operations such as cruising, stalls, landings, aerobatics, and air-to-air tracking
