TIA
It's very straight forward, flight time is considered from when the craft moves under its own power for the intention of flight to when it comes to a stop at the destination after completion, chock to chock. Tacho is for engine maintenance, the timer will vary according to engine load or RPM, Flight switch is for airframe maintenance and VDO is engine running time, usually a very close approximation, unless you spend 20 minutes warming up that is.
