If you are checking out on a type that you have not flown in command before, then it should be logged as dual instruction. There is no shame in logging dual hours. In most cases that I have seen as a flying instructor, the logging of ICUS is a sham because in all cases the instructor has either given hints, actively disagreed with the course of action taken by the ICUS crew member, or quietly prompted during the flight. I am suspicious of any new pilot that I consider hiring, if he has logged loads of ICUS time. Same with Instrument flight time. In my experience most of it is faked. Either the instrument time has been claimed merely because it an IFR flight plan, regardless whether or not the trip was flown in a blue sky. or sometimes you see pilots logging taxy time also as I/F time.
Often you see instructors logging simulated I/F time even though they have not touched the controls because the student is doing the actual handling. I recommend you log flying hours with total honesty. Discerning interview boards can pick fake hours quite easily. In my view, any flight test such as I/R where an instructor or testing officer has direct responsibility for the safe operation of the aircraft, should be logged by the pilot undergoing the check, as dual - not pilot in pilot in command. If the test officer is required to simulate emergencies as part of the test, then he is directly responsible for supervising the actions of the pilot. By definition therefore, the test officer is in full command. Therefore the pilot under test must log dual. States Rules differ of course, but you can have only one pilot in full command, and that must be the examiner.
