This may seem a silly question and it probably is, but has anyone entered first engine start and taxi time in their pilot logbooks prior to first flight? I'm dying to record actual operating activity of my RV-8 in my logbook, but not sure it's appropriate if no flight is involved. I do have an "A/C Familiarization" in my customized logbook; maybe I'll put it there with no takeoffs or landings recorded but total time included. Thoughts, anyone?
