How long does a pilot need to log to maintain their currency?

To maintain currency as a pilot, the requirement is to have made at least one takeoff and one landing within the preceding 90 days. This is particularly important for pilots operating under general aviation rules, where landing proficiency directly affects safety and operational competence.

A pilot must complete this within the specified 90-day window to ensure they are current and capable of handling the aircraft safely as well as being familiar with any changes in procedures or regulations. This cadence is designed to help pilots reinforce their skills regularly, minimizing risk and maintaining a solid foundation of flying competency.

The other options regarding flight hours or a longer time span do not align with the specific regulatory requirements for maintaining currency in terms of takeoffs and landings; hence they do not meet the exact criteria set forth by aviation authorities.
