Flightpath prediction can substantially enhance the guidance and control ca
pabilities offered by a novel display type that presents guidance informati
on in a three-dimensional format. Based on pilot-centred requirements, a pr
edictor design for longitudinal motion is proposed to achieve minimum pilot
compensation for controlling the predictor-aircraft system. Key configurat
ion factors of the pilot-predictor-aircraft system are identified and optim
ized. The compensatory control issues are verified in a simulation test pro
gram.
