I log up to 16 hours per sector
Laggard, folks can do more than that now.
Not that I'd want to, nor your 16. A one line entry at one stage could be 10 hours, but that could include possibly say 6 hot refuels and 60 landings, or any number of engine starts. Used to put a tick on the windscreen with a chinagraph to record landings and add up at the end of the day.
