What does RNAV/GNSS (LNAV Minimums) represent?

• A. A type of precision approach
• B. A type of non-precision approach
• C. A type of APV approach
• D. A standard landing procedure

Answer: (B)

RNAV/GNSS (LNAV Minimums) represents a type of non-precision approach. This classification is based on the vertical guidance limitations inherent to the approach method. Non-precision approaches, such as those that utilize LNAV (Lateral Navigation) minimums, do not provide vertical guidance, which means that the pilot must rely on their own vertical position and their ability to maintain altitude during the approach. In contrast, precision approaches, like those utilizing ILS (Instrument Landing System), provide both lateral and vertical guidance, allowing for more precise control of the aircraft's descent. APV (Approach with Vertical Guidance) approaches, such as those using LNAV/VNAV (Lateral Navigation/Vertical Navigation), do provide some vertical guidance but are not classified as precision approaches. Therefore, understanding RNAV/GNSS (LNAV Minimums) as a non-precision approach helps clarify the limitations and procedures associated with this method of navigation during landing.
