The VProf Tutor is a computer-based intelligent tutoring system (ITS) that teaches the use and understanding of vertical profile navigation modes to MD-11 pilots. This ITS is a proof-of-concept implementation of GT-ITACS (Georgia Tech-Intelligent Tutoring Architecture for Complex Systems). GT-ITACS is a domain- and platform- independent intelligent tutoring system shell designed to train operators of complex-dynamic systems. This paper introduces the features of GT-ITACS, using the VProf Tutor to illustrate the capabilities of the system.
