An RNAV (Area Navigation) approach utilizes GPS or other navigation systems for guidance. RNAV approaches are designed to enhance the efficiency and accuracy of navigation by allowing aircraft to fly on any flight path within the coverage of ground-based or satellite-based navigational aids.

The use of GPS is significant in RNAV approaches because it provides precise positioning and allows for predefined flight paths that can be tailored to optimize operations in the terminal area. Additionally, RNAV approaches can incorporate a mix of various navigational aids such as VORs and NDBs, but primarily depend on advanced satellite navigation systems.

This approach enhances safety and efficiency by enabling aircraft to approach runways that may not have traditional navigational aids available. It is an essential component of modern aviation navigation, allowing for more flexible flight paths and improved access to airports, especially in challenging environments.
