count the hours in your log book,
Excellent choice of wording Londonblue... A person (not even a pilot) can write whatever they want in their logbook. However, only time spent as a qualified and required flight crew member
counts for anything. It is simply fraud to attempt to convince someone that you have flying experience which you were not entitled to credit to yourself.
Aside from a role as a qualified and required instructor, an aircraft's type certificate will state if a second pilot is required. For single engined Cessnas, a second pilot is not required.
