What is the latest a student may complete their jumps according to the BSRs?

The correct answer indicates that all jumps must be completed by sunset. This guideline is established to ensure safety during skydiving operations. As daylight diminishes, visibility decreases, which can significantly impact a jumper's ability to assess their surroundings, execute safe landings, and navigate in the air.

Flying in the dark poses a higher risk, particularly for student jumpers who may still be developing their skills in making informed decisions during freefall and landing. By requiring that jumps be completed while there is still adequate light, the regulations minimize the potential for accidents that could arise from decreased visibility.

In contrast, completing jumps by midnight, sunrise, or noon does not align with the safety measures embedded in the Best Safety Recommendations (BSRs). Midnight would allow for jumps during conditions where darkness could hinder visibility and safety. Requiring jumps to be completed by sunrise would mean that students might be jumping in the early morning hours when it is still dark. Noon does not account for decreasing light conditions as the day progresses, especially in times of the year when daylight hours vary significantly. This consistent requirement to complete jumps by sunset ensures a safer environment for student skydivers.
