I cant speak your neck of the woods, but over here if you claimed PIC time without doing landings or T/Os I think you would be charged with falsifying flight time, and rightly so.These days I fly a twin, the young lady in the right seat on revenue flights does most of the work and when flying the aircraft {including T/O and Ldg} logs it as PIC, under supervision, on Non Rev legs she is left seat and logs it as PIC.When I flew the heavy stuff we had a very formal system of when F/Os could log PIC under supervision, not used much as we hired most with 5000 hours or more, thus no need to log time for upgrades.
