Approach and landing of an aircraft equipped with a roll-rate-command/bank-angle-hold flight control system were investigated, using a moving base simulator. Pilot comments and ratings following systematic variation of roll mode time constant, maximum available roll rate, and pure time delay were noted. Results indicate that roll response criteria are too lenient. The more precise control of bank angle, available with the flight control system, leads to a higher internal standard of the pilot for his judgement of roll response quality. These control systems must comply with more strict requirements than conventional systems to obtain the same degree of pilot approval. Based on the experiments, limits/boundaries in existing criteria are redefined and criteria are proposed.
