What visual cues assist in transitioning from an approach to landing?

The correct choice emphasizes the importance of runway markings and visual references in aiding pilots as they transition from an approach to landing. Runway markings, such as centerlines, thresholds, and aiming points, provide critical guidance for pilots, helping them align with the runway during descent and final approach. These markings are standardized, so pilots can rely on them for consistent performance across different airports.

Additionally, visual references, including the surrounding terrain, lighting systems, and the runway itself, are essential for situational awareness and orientation during the landing phase. They help pilots confirm their approach path and ensure proper alignment with the runway. Together, these visual cues create a clear picture for pilots, enhancing safety and accuracy during one of the most critical phases of flight.

Other options, while they may involve aspects of flight, do not directly contribute to the visual transition from approach to landing in the same manner as runway markings and references. For instance, traffic lights and runway colors may not be universally applicable or helpful, and GPS signals along with flight indicators serve more for navigation than for visual approach confirmation. Weather conditions and altimeter readings provide important information but do not serve as direct visual cues that assist in the landing process.
