Abstract

This paper looks at incorporating time information into a waypoint trajectory-generation technique known as Vector Field Guidance to give a 4D trajectory generator henceforth known as Tensor Field Guidance. The time-based information is local in that it is relative from waypoint to waypoint. We envisage that a higher-level controller or an Air Traffic Management system automates the waypoint generation, while our approach optimizes the travel time between waypoints. We present results from simulations, showing an increase in accuracy of “Distance to go” estimates over traditional “as-the-crow-flies” yielding less error in time-based arrivals.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
