First Officers log co-pilot time when crewing an aircraft whose flight manual requires more than one pilot to crew it when they are the support/monitoring pilot, and command practice time when the Captain of the aircraft is approved by the operator to give command practice and the co-pilot is flying pilot and carrying out the duties of P-in-C. The practice of signing the trip record by the captain and is recorded by the operator is a suitable alternative to signing a logbook.
Pilots who fly as support pilots in aircraft approved for single-pilot operation, usually Part 135 aircraft, which do not have a fully functioning co-pilots instrument panel equivalent to the pilots panel are not permitted to log command practice.
To summarise:
To log command practice:
- the co-pilot must be the flying pilot
- the co-pilot must carry out duties of p-in-c
- the aircraft flight manual must require two pilots
- the captain must be authorised to give command practice
- either the logbook or the trip record must have been signed by the captain to record the event.
