What is an RNAV approach?

An RNAV approach, or Area Navigation approach, is defined as a precise flight path navigation method that utilizes advanced navigational technology, such as GPS, to guide aircraft along a predetermined route to their destination. This system allows pilots to fly a specific trajectory in the airspace, which enhances safety and efficiency during approaches. Unlike traditional navigation methods, which rely on ground-based signals and visual references, RNAV approaches can leverage satellite signals to provide accurate position data.

This capability is particularly crucial in modern aviation, as it supports more flexible and efficient routing, reduces the reliance on conventional navigational aids, and allows for approaches to airports that may not have extensive ground-based navigation facilities. The increased precision offered by RNAV approaches means they can be seamlessly integrated into the overall air traffic management system, enabling higher density operations and improving arrival and departure procedures in busy airspace.
