And yet most, nay all, air operators specify minimum hours for any flight crew vacancy. Go figure?
Certainly as a HR function, yes. The published minimums are really quite meaningless, however, as it's the competitive minimums that rule the day.
A company that advertises a published minimum of 1,500 hours, but which is hiring pilots with ample international heavy experinece and 15,000 hours for example, hires at the competitive minimum established by those applicants competing for the job.
