Abstract: Guidance and control techniques have been developed to permit accurate nonlinear pathfollowing in the terminal area using an MLS & DME database. The elements of the system including trajectory generation, mean-wind estimation, feedforward and pertubation control are described and the performance of the integrated system delineated. The investigation was made with the aid of a sophisticated digital simulation, including modelling of the sensor and environmental noise. A conventional jet transport was the subject aircraft. A conclusion of the investigation was that the integrated guidance and control system was adequate to the task of path tracking with errors within the resolution of ATC radar. A corollary is that a degraded MLS, relative to that required for the landing task, operating at low scan rates provides navigational data of sufficient accuracy to perform the curved approach task.
