Prediction and Evaluation of Flying Qualities in Turbulence.

Abstract

A method for predicting tracking performance of Class 4 airplanes in turbulence has been validated through a moving-base simulation of 16 F-5 and A-7 configurations on the Northrop Large Amplitude Flight Simulator. The method is based on pilot model theory and predicts root mean square tracking errors for piloted tasks in turbulence. Both lateral and longitudinal dynamics are considered, and the accuracy of the method is assessed. Specification design criteria are evolved from the simulation data for bank angle and pitch angle attitude hold tasks in turbulence. Digital programs that perform the prediction calculations accept arbitrary equations of motion and are available on request from the United States Air Force; a user's guide is included in the report, along with complete tracking error, gust level, and pilot rating data from the simulation.
