The current research deals with planning problems related to instructors training in simulator flight training programs. It is a part of our development work in optimal training programs to support the cost effective design of instructor/operator stations(IOS). A flight simulator is a complex device which can be used to train students and instructors, whose training requirements and methodologies are quite different. This paper deals with this complex man-machine interface planning problem, presents a model for the instructors training process, and develops a methodology for determining optimal training plans.
