System comprised of spinning weights that maintain a specific orientation•1947: The U.S. Air Force successfully tested the first fully functioning autopilot system. The system controlled takeoff, landing, and flight path.•These early systems were prone to error and required a full staff to work them•Now: “Fly by wire” systems are the most common. Computers do most the flying.FunctionsFunctionsGuidanceGuidanceMeasures the condition of the aircraftMeasures the condition of the aircraftOuter LoopOuter LoopDoes not actually guide the aircraftDoes not actually guide the aircraftFeeds the values into the control loopFeeds the values into the control loopFunctionsFunctionsControlControlDoes the actual workDoes the actual workReceives values from guidance and Receives values from guidance and controls the aircraft.controls the aircraft.Two major controllers:Two major controllers:LongitudinalLongitudinalLatitudinalLatitudinalLongitudinal ControlLongitudinal ControlLongitudinal ControlLongitudinal ControlLatitudinal ControlLatitudinal ControlMATLABMATLABSimulation AttemptSimulation AttemptQuestions, Comments, Violent Questions, Comments, Violent
