Quit logging at 11,000 hours.
The FAA requires a "record" of flight time to be kept, but my airlines computer print-outs satisfies that requirement.
(I walked into a FSDO office to ask that specific question)
Have kept all my small and big logbooks and may one day log the time I have flown over the last couple of years.
Not going to apply for another job anyway: If I get laid off or present company goes Tango Uniform, I am ready to kiss flying goodby...(17 jobs, 50 types and counting...)
