Abstract:

The material presented describes the test system, criteria and results of a flight evaluation of a force wheel steering technique designed to permit the pilot efficient and effective entrance into the outer loop of an automatic flight control system. The force wheel steering concept was evaluated for six control conditions ranging from fully manual to fully automatic with force wheel steering. These levels of automaticity with force wheel steering served as the base line for the correlation of pilot and vehicle performance and pilot burdening. The results indicate that force wheel steering can be effectively utilized as a control technique for the lowering of current IFR landing minimums. Expected reductions in pilot work load with increasing levels of control automation were noted. System performance for all control modes evaluated was comparable or superior to that observed during fully manual approaches. Pilot opinion and attitude measures indicated generally favorable attitudes toward the force wheel steering concept. Areas requiring further developmental effort were suggested by the analysis of the recorded performance measures and pilot questionnaire data. Author
