In particular, this paper reports on an examination of the RNP RNAV-based algorithm of the Relative Position Indicator (RPI) of the projected aircraft over a range of expected geometries. First, a simple two segment route projected onto a straight path will be examined. The accuracy and behavior of the projected aircraft indicator depends on route conformance and the geometry of the two route segments, ranging from a fairly benign straight adjoining segments to a challenging 180 degree turn such as a downwind to the base leg of an approach. More complex multisegmented instances where the waypoints defining the reference route and the RPI route are not colinear will also be analyzed and compared. The simulation tool replicates the views of terminal controllers and will be used to identify any anomalous projected-aircraft behavior.
