Looks like those that fly in FAA land (GOMEX or else where) with very easily 10-12hrs a day blade turning time, but only 5-8hrs wheels up are getting cheated out of some time...
Depends.... One can log time form the time the aircraft first moves under its own power till the time it stops. Therefore, if you hot re-fuel then you can log all the time.
Can I pick which definition I want to use?
Nope---when in Rome......as they say. If you are applying for an FAA certificate then all your flight time needs to be logged in accordance with their rules.
