Some people think that you start logging flight time as soon as you sign for the aircraft and walk out of the crewroom. Sure, you are responsible for an incident that occurs as a passenger slips on the aircraft step and topples gracefully to the ground. Or a kid impales himself on the pitot tube. But you can't log anything until the blades are turning with the intention of flying.
No logging ground runs - apart from being illegal, contemptible and the act of a desperado, only tragic dunces would do it.
As a newby in the ADF, we were often tasked with the crappy jobs, like ground runs (unloggable) and compass swings. At least we flew a bit on a compass swing - pick it up, turn 30 degrees, put it down. BUT! We could only log 50% of the total time.
