What is the name for the portion of the runway that is marked with white arrows pointing toward the displaced threshold?

The correct answer identifies the portion of the runway marked with white arrows pointing toward the displaced threshold as the Non-landing Portion. This area indicates that while the arrows point toward a threshold that may not be used for landing, it serves to guide pilots regarding where the usable part of the runway begins for takeoff, especially in conditions where the threshold has been physically displaced. The visual aid of the white arrows helps maintain safe operational practices by clearly marking the boundary of where landing should not take place.

The other options may refer to different parts or concepts related to runways. The Touchdown Zone is generally the area on the runway where aircraft are expected to land; the Bearing Strip may refer to a specific type of pavement used to support aircraft during operations; and the Runway Threshold itself marks the beginning point of the runway for landing, which is typically the edge used for landing and not the area marked by the arrows leading to a displaced threshold.
