This course covers the Flight Management System (FMS) and Flight Management and Guidance Systems (FMGS) used in aircraft. The FMS assists the pilot in flight planning, navigation, performance management, guidance and flight progress monitoring. It can be interfaced with the autopilot or flight director to automatically guide the aircraft along the selected path and to tune the navigation radios. The FMGS provides automated en-route and terminal area guidance using defined procedures such as Standard Instrument Departures (SIDs), Standard Terminal Arrival Routes (STARs), holding patterns and procedural turns.
