On deciding display dynamics requirements for flying qualities

An approach for deciding display dynamics is presented that is based on multivariable control analysis and synthesis techniques, specifically the structured singular value, and uses the optimal control model to represent nominal pilot behavior. Given an uncertainty structure for the nominal model that reflects likely pilot variabilities, structured singular value techniques are used to examine and determine display dynamics that strike a balance between the goal of optimal system performance and the goal of tolerance to pilot variability. The approach is illustrated by an example, the results of which support its potential utility
