Which of the following is NOT a type of non-precision approach?

The Instrument Landing System (ILS) is considered a precision approach rather than a non-precision approach. This classification arises from the way ILS provides lateral (localizer) and vertical (glideslope) guidance to pilots, allowing for more precise landing capabilities, particularly in low visibility conditions. In contrast, non-precision approaches, such as NDB (Non-Directional Beacon), VOR (VHF Omnidirectional Range), and RNAV/GNSS (Area Navigation/Global Navigation Satellite System), only provide lateral guidance without a defined vertical path. These approaches rely on different navigational aids and do not have the same level of accuracy in vertical guidance that ILS approaches possess, making them less precise. Understanding this distinction is crucial for pilots when determining the appropriate approach type for a given situation.
