But most people seem to miss the after landing part of the definition. Which would require you to leave the ground first.
Based on the FAA definition I would say that both of the cases above aren't technically loggable.
I think this all depends on what type of flying you are doing.
Like you - in the military it is takeoff to landing + 5 mins.
Naval aviation even had a definition for "purpose of flight" depending on certain circumstances (having crossed the hold short or in tension on the cat for example) for safety investigation reporting purposes; it didn't have anything to do with logging time, but you would think they would be the same huh?
All that time spent in marshal doesn't count for squat

Isn't civilian time (and least in GA) logged based on the Hobbs times?
Do airline actually log block to block or only paid block to block?
I have heard many civilians use the first part of Otto's explanation as basis of logging time.
Interesting question and one that I am sure has been addressed on the forum before. You might want to try a quick search of the archives.
