Remarks: This is the area where you must list the city, town, or village, and state abbreviation when a change of duty status occurs. You should also explain any unusual circumstances or log entries that may be unclear when reviewed later, such as using the adverse driving conditions exception.

In a pilot's logbook, the "Remarks" section is used to satisfy specific FAA regulatory requirements under 14 CFR 61.51. While much of the logbook is for personal record-keeping, certain entries in the remarks are mandatory for the time to "count" toward certificates or ratings. For instance, when logging instrument time for currency, you must include the location and type of each instrument approach accomplished, as well as the name of the safety pilot if one was required. For flight training, the instructor must sign the remarks and include their certificate number and expiration date to "certify" the dual instruction. Other required entries in this section include endorsements for specific operations, such as high-performance, complex, or tailwheel transitions. If you are performing "Pilot in Command Under Supervision" (PICUS), the supervising pilot must attest to the training in this column. While pilots often use the remarks for personal notes (like "First landing on grass!"), from a legal standpoint, this area is primarily for the signatures, certificate numbers, and specific maneuver validations that prove a pilot has met the "recent flight experience" or "training" requirements of the Federal Aviation Regulations.
