This technical report describes a method for assessing the performance of automatic tracking systems against various metrics. These metrics are grouped in the categories of track establishment, track maintenance, track error and false tracks. A desired performance level is defined for each metric, and the probability that a particular track will meet this performance level is empirically approximated from archived sensor data. The individual metric probabilities are combined using a ...
Airsickness is a common occurrence among aircrew trainees, particularly during the initial training phase. It is well known that motion sickness afflicts the passenger far more than the driver of the vehicle. The objectives of this handbook are to assist student-navigators to dispel myths about airsickness, to recognize the mechanism of airsickness during their initial training, to provide some practical countermeasures and to propose ...
The term Push-Pull Effect' (PPE), popularized in the last few years, has been used to describe observed reductions in G-tolerance during acceleration that was preceded by exposures to hypogravity (i.e. <+1Gz). The phenomenon can be easily interpreted as occurring only in classical bunt-then-pull' maneuvers. However, our review of previous research and operational evidence suggests a much broader spectrum of at-risk situations and adverse physiological and ...
