What is a key benefit of using RNAV?

Using RNAV (Area Navigation) provides significant advantages in modern aviation, particularly in terms of efficiency and operational flexibility. One of the main benefits is the reduced dependence on radar vectoring, which optimizes the use of airspace. RNAV allows aircraft to navigate using a combination of ground-based navigational aids and satellite data, enabling more direct routing and reducing the need for air traffic controllers to issue frequent radar vectors. This results in a more streamlined flight path, thereby conserving fuel and reducing flight times.

Additionally, RNAV procedures can lead to improved traffic flow in busy airspace and enhanced safety by providing more precise navigation capabilities. The system allows pilots to fly predetermined routes that align more closely with the direct flight path, minimizing detours and enhancing overall efficiency in the national airspace system.

Therefore, option C accurately reflects the inherent advantages of using RNAV in aviation operations.
