What outcome is associated with landing after sunset during solo flights?

Landing after sunset during solo flights is associated with an increased risk of accidents primarily due to reduced visibility. Pilots often rely heavily on visual references to make safe landings, and as daylight fades, the lack of natural light can impair depth perception and the ability to gauge distances accurately. This inherent limitation increases the challenge of recognizing runway features, detecting potential obstacles, and effectively managing the situational awareness needed during landing.

Additionally, many training regulations and personal proficiency levels dictate that student pilots should not perform solo flights at night. This restriction is designed to ensure that novice pilots develop their flying skills and judgment in safer, more controlled environments, ideally in daylight when visibility is optimal. The circumstances of low light conditions present additional hazards that a pilot may not yet be equipped to handle independently, further indicating the increased risks associated with such landings.

While other choices touch upon relevant aspects—like the loss of instructor support or difficulties in technique—the emphasis on accident risk underscores the primary concern of safety and situational awareness during solo flight operations conducted at night.
