ABSTRACT
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.
