What is the primary characteristic of a Non-Precision Approach?

A Non-Precision Approach primarily relies on azimuth information for lateral guidance, without the benefit of vertical guidance such as a glide slope. In this type of approach, pilots are directed to an intended runway using navigational aids that provide horizontal guidance or lateral positioning, but they must rely on visual references or other means to complete their descent to the runway.

In the context of the other options, glide slope information, typically associated with Precision Approaches, provides both lateral and vertical guidance, which is not available in a Non-Precision Approach. Visual cues can be important during the landing phase, but they are not a defining characteristic of the approach itself. Radar data might support some navigational aids but does not define the essence of a Non-Precision Approach. Therefore, the focus on azimuth information highlights the approach’s reliance on lateral positioning without vertical guidance, which is crucial in distinguishing it from other types of approaches.
