What type of approach can provide a means to descend and land safely in low visibility?

The choice that best allows for a safe descent and landing in low visibility conditions is precision approaches. Precision approaches utilize advanced guidance systems, such as Instrument Landing Systems (ILS), which provide accurate lateral and vertical guidance to pilots. This high level of guidance ensures that aircraft can approach the runway with a minimum decision height and visibility, making it feasible to land safely even when visibility is significantly reduced.

Precision approaches are designed specifically to assist pilots in navigating the final phases of landing under difficult conditions, ensuring a higher level of safety compared to other approach types. This capability is critical in low visibility scenarios, where pilots rely on instruments rather than visual cues to execute landings.

While visual approaches rely on pilots being able to see the runway, non-precision approaches do not provide the same level of vertical guidance, making them less effective in poor visibility. Standard instrument approaches may offer some guidance but lack the accuracy and reliability needed compared to precision approaches. Therefore, precision approaches are the most suitable for managing low visibility landings.
