Abstract
The pilot's longitudinal control of an aircraft making a carrier approach is studied using systems analysis techniques. The pilot, airframe, and mirror optical landing aid are considered as elements in a closed-loop system. Mathematical expressions to approximate each element are derived or described. Various possible piloting techniques are examined by appropriately varying the pilot's transfer function, and by closing multiple control loops around the system. The question of whether the pilot should use stick or throttle for altitude control is examined. It is shown that the minimum approach speeds of five out of seven jet aircraft, all limited by the ability to control altitude and arrest rate of sink,'1 can be predicted if it is assumed that the pilot uses throttle for altitude control.
