A Manual Control-Display Theory Applied to Instrument Landings of a Jet Transport

This paper presents an illustrative application of a theory for manual control displays to the instrument landing approach of a large subsonic jet transport. A methodical procedure is disclosed for formulation of compensatory display-control systems. Manual approach height and lateral position control are treated in multiloop dynamic analyses so as to select preferred variables for measurement and display. Closed-loop system performance and pilot scanning and workload measures are also evaluated. The example concludes with the "prediction" of a preferred display arrangement. Comparison with an FAA Category II instrument panel arrangement selected by an air line operating the example aircraft shows the predictions to be remarkably accurate.
