It becomes mentally grey when the aircraft owner is being reviewed.
Why would it be “mentally grey”? To turn this around, what would the instructor log? ICUS? Dual? Supernumerary? There can only be one PIC .
Or does the instructor not have the power to pull back on the stick when the pilot under review gets it wrong enough to set up an incident.? Good luck finding an instructor prepared to accept those terms from any pilot under review - aircraft owner or not.
