Details of the
UK requirements for the information to be recorded in a personal flying log are in Article 228 of the ANO 2016:
(4) The information recorded in accordance with paragraph (3) must include—
(a) the date, the places at which the holder of the log embarked on and disembarked from the aircraft and the time spent during the course of a flight when the holder was acting in either capacity;
(b) the type and registration marks of the aircraft;
(c) the capacity in which the holder acted in flight;
(d) information about any special conditions under which the flight was conducted, including night flying and instrument flying; and
(e) information about any test or examination undertaken by the holder of the log whilst in flight.
FCL.050 requires a personal flying log to be kept but leaves the detail up to individual member states to determine. AMC1 FCL.050 provides one acceptable means of complying with the regulation and ANO Article 228 provides an alternative means
in the UK. You are free to choose which means of compliance you employ.
