What is an RNAV approach?

An RNAV approach, or Area Navigation approach, is a method used in aviation that enhances the navigation capabilities of aircraft. It allows a pilot to fly on any desired flight path rather than being limited to traditional ground-based navigation aids. This approach utilizes waypoints, which are predetermined geographic locations identified by coordinates. RNAV systems take advantage of both satellite systems and onboard navigation databases, providing pilots with the flexibility to execute precision approaches into airports.

The key feature of RNAV approaches is their ability to improve efficiency and accuracy in navigating complex airspace and procedures, ultimately supporting more precise and flexible flight operations. This technology is integral for modern aviation and increases safety and effectiveness when flying into airports with specific routing requirements.

Understanding this definition is crucial for pilots, as it underscores the importance of area navigation capabilities in ensuring safe and efficient access to airports.
