Abstract: A technique is provided to measure an alignment of an imaging device of a guided projectile containing an imager and a world coordinate frame, and includes producing a pure rolling motion of a body of the projectile, capturing a series of images of an imaging device calibration target over a range of body roll angles of the rolling body, measuring the roll angles of the rolling body with respect to a world coordinate frame as defined by the imaging device calibration target, simultaneously estimating alignment angles of the imaging device and misalignment angles associated with an orientation of the body, and estimating a rotational transform between an imaging device coordinate frame and a body coordinate frame based on the estimated alignment angles and misalignment angles.

Abstract: A method has been found for assessing an aircraft approach to landing on a shipboard landing surface. The method includes a comparison of an identified aircraft performance with the mean or median of a baseline data set. The baseline data set is assembled from a multiplicity of actual approaches to landing data that are selected for relevance and then statistically evaluated. A high data recording rate captures the pilot's control inputs and allows evaluation of the pilot's manual efficiency of input to controls. The method is particularly useful to evaluate performance under conditions in which evaluation by human observation is limited or evaluation against guidelines produces less meaningful results.

Abstract: According to typical inventive practice, a baseline describing a statistical distribution is established for a set of historical occurrences of an event. Comparison is made between the baseline and at least one current occurrence of the same event. Any current occurrence that is anomalous vis-à-vis the baseline is considered a possible leading indicator. According to some inventive embodiments of graphical presentation of such comparison, at least one graphical baseline comparative display component is rendered that includes a “bar” (describing a historical statistical distribution with respect to a criterion pertaining to occurrence of an event) and a “slider” (describing one or more current occurrences of the event). The bar includes at least one band representing a statistical mean range, and at least one band representing a statistical outlier range. Situation of the slider along the bar indicates whether and to what extent the current occurrence(s) is/are anomalous vis-à-vis the baseline.
