What is the requirement for a pilot to carry passengers at night?

To carry passengers at night, a pilot is required to have completed two takeoffs and landings to a full stop during nighttime conditions within the preceding 90 days. This requirement ensures that the pilot maintains proficiency specifically under night flying conditions, which can differ significantly from daytime operations due to reduced visibility and the need for different situational awareness.

The focus on night takeoffs and landings is critical because pilots need to have recent experience specific to nighttime operations to ensure safety for both themselves and their passengers. This requirement emphasizes the importance of practice in the unique challenges presented by night flying.

While the other options may involve takeoffs and landings, they either do not specify the requirement for night flying or do not meet the specific condition for taking passengers at night. For example, some options could refer to daytime operations or different recency requirements that do not address nighttime proficiency, making them less relevant in this situation.
