As an operator of a wheeled u/c helicopter, I always add on the estimated ground taxying time where appropriate when logging personal hours flown. The aircraft hours for the tech log get copied to the minute via the w.o.w. controlled data computer, which is interrogated during or after shutdown. So unless I fly to and from helipads, my log book hours show a few more minutes than the aircraft tech log hours.
Looks like folk in my position can now add on a few more minutes each trip (not that I'm hours grabbing; it really matters not a lot after thirty years or so).
