Proper record keeping of aeronautical experience is crucial for aviation professionals. Incorrect pilot logbook entries can result in tedious paperwork, loss of a job opportunity, or possibly certificate action for falsifying records. Second In Command time is useful aeronautical experience that can help qualify a pilot for additional ratings. Always refer to the most current edition of the Federal Aviation Regulations, as they may change.
Determine who is the Pilot-In-Command for the flight, and who is Second-In-Command. These are commonly abbreviated PIC and SIC. The pilot who is the final authority for the operation of the flight, responsible for all the decisions and actions aboard the aircraft is the Captain and Pilot-In-Command. The other pilot occupying a crew member station is the Second-In-Command.
Determine the flight rules under which the flight is operated. Flights conducted under common carriage of an Air Carrier (Part 121 and 135) are required to have a flight crew of at least two pilots and name one the Pilot-In-Command and the other Second-In-Command. Flights operated under private contract (Part 91) may be conducted by a single pilot depending on the type of aircraft to be flown. Second-In-Command time may be logged if a second pilot is required by the operating rules under which the flight is conducted.
Determine the minimum crew required for the type of aircraft used. Second-In-Command time may be logged if a second pilot is required by the category, class, or type of aircraft being flown.
Determine the total flight time. As of January 2010, flight time is defined as starting when the aircraft first moves under its own power to the times that it stops at its destination.
Record the applicable amount of flight time. If the flight qualifies a pilot for Second In Command time, use the logbook column titled "SIC" or use a blank column. Round the time to hours and tenths of an hour (ex. 4.3 hours). Only include time that the pilot was performing the duties of a required flight crew member. Deduct time for flight legs that only required one pilot or any duration fulfilled by a relief pilot
