Some extracts from the new CAP 804
3.4 Instruction time
A summary of all time logged by an applicant for a licence or rating as flight
instruction, instrument flight instruction, instrument ground time, etc. may be logged
if certified by the appropriately rated and/or authorised instructor from whom it was
received.
2.2 Pilots applying for a licence or rating are strongly advised to use a log complying with
Part-FCL.050 AMC No.1 to facilitate its issue.
4 Format of the record
4.1 Details of flights flown for commercial air transport may be recorded in a
computerised format maintained by the operator. In this case an operator should
make the records of all flights operated by the pilot, including differences and
familiarisation training, available upon request to the flight crew member concerned.
4.2 For other flights, the pilot must record the details of the flights flown in a log. The
following format is strongly recommended.
5 Presentation of flight time record
5.1 The holder of a licence or a student pilot shall without undue delay present his flight
time record for inspection upon request by an authorised representative of the
Authority.
5.2 A student pilot shall carry his flight time record log with him on all solo cross-country
flights as evidence of the required instructor authorisations.
It also contains a sample log book.
