A pilot logbook is an official record in which a pilot logs and tracks their flight experience. The logbook is used to verify the flight experience of the pilot. For each flight the pilot should record the name of the PIC, the date of the flight, aircraft type and registration, flight time of the flight and accumulated total flight time. According to Part-FCL, flight crew logbook entries should be made as soon as practicable after any flight undertaken.

FCL.050 Recording of flight time

The pilot shall keep a reliable record of the details of all flights flown in a form and manner established by the competent authority.

INSTRUCTIONS FOR USE
(d) FCL.050 requires holders of a pilot licence to record details of all flights flown. This logbook enables pilot licence holders to record flying experience in a manner which will facilitate this process while providing a permanent record of the licence holders flying. Pilots who fly regularly aeroplanes and helicopters or other aircraft categories are recommended to maintain separate logbooks for each aircraft category.

(e) Flight crew logbook entries should be made as soon as practicable after any flight undertaken. All entries in the logbook should be made in ink or indelible pencil.
