What is the primary feature of runway aiming point markings?

The primary feature of runway aiming point markings is two rectangular markings located on the runway surface. These markings serve as visual cues for pilots, indicating where they should aim to touch down when landing. The positioning of the two rectangles helps in aligning the aircraft with the centerline of the runway, which is especially important in ensuring safe and accurate landings. This standard design enhances situational awareness for pilots, contributing to better landings and overall airport safety.

Other options, such as single circular markings or broad black stripes, do not serve the same function in helping pilots determine an appropriate landing point. Diagonally striped markings can indicate different areas on the runway but do not function as aiming points. Thus, the distinct presence of two rectangular markings is crucial for guiding pilots effectively during their approach and landing phases.
