Abstract : The carrier landing process involves the interaction of ship motions, the optical landing system, the pilot/aircraft combination, air wake disturbances, and the Landing Signal Officer. Mathematical models for these elements are formulated, and methods are presented for determining terminal landing errors and resulting operational performance indices. A new concept is described for stabilizing the optical landing system against carrier deck motions. Termed 'compensated-meatball stabilization,' this technique theoretically permits landing operations in more severe sea states through display quickening. The results of simulator experiments support the theory, and additionally show a performance-limiting factor related to the aircraft's lift curve slope. This factor is analyzed and its performance-limiting aspects for both manual and automatic control are delineated. The use of direct lift control (DLC) as a means of overcoming such performance limits is analyzed and discussed. Consideration is also given to the effects of using an idealized, rather than a fixed, glide slope as means of reducing accidents, and to the possible uses of predicted deck position and contingent minimum prediction time and accuracy requirements.
