Every 5 years, a pilot must fly as what to maintain currency?

To maintain currency, a pilot must log flight time as either Pilot in Command (PIC) or Second-in-Command (SIC) in any aircraft. This requirement allows pilots to stay proficient and updated on their flying skills, regardless of the specific type of aircraft. The essence of maintaining currency is not limited to specific aircraft categories, as long as the pilot holds the necessary ratings for those aircraft.

This flexibility is vital because aviation encompasses a wide range of aircraft types and operations. By allowing flight experience in any aircraft, the regulation makes it easier for pilots to find opportunities to fly and stay current, which is crucial for safety and operational competency.

The other choices restrict the application of currency to specific aircraft types or operations, which do not align with the intention of maintaining a broad currency requirement across various aircraft.
