Abstract: A system for flight training includes one or more non-transitory computer-readable memories storing instructions one or more processors executing the instructions to perform operations. The operations include creating activities corresponding to flight training requirements; initializing a state and a cognitive load for each activity, wherein the state comprises at least one of review state, rollover state, skip state, or new state, and the cognitive load is indicative of cognitive effort; storing the activities and respective states and cognitive loads in a database; selecting a subset of the activities; assigning the subset to a lesson; recording a score for activities in the subset, the score reflecting a student's performance of the activity during the lesson; storing the scores in the database; updating the state of an activity in the subset based on the core recorded for the activity; and updating the cognitive load of activities.
