This section provides the basic radio principles applicable to navigation equipment, along with the operational knowledge required to use these systems during instrument flight. A clear understanding of navigation system operation is essential for accurate course tracking and effective instrument flying.
This knowledge provides the framework for instrument procedures such as standard instrument departures (SIDs), departure procedures (DPs), holding patterns, and instrument approaches. Each of these procedures depends on accurate attitude instrument flying combined with precise navigation and course guidance.
Modern instrument flying may involve traditional ground-based navigation systems as well as advanced technologies such as required navigation performance (RNP), flight management systems (FMS), head-up displays (HUD), and radar navigation.
The following topics explain the principles, systems, and technologies used for navigation during instrument flight and provide the foundation for understanding IFR procedures and approach operations.
