While the 1500hr requirement doesn't state “ATP,” that will be the result.
Not that many pilots get their ATP right at 1500 hrs. Many exceed 3000 hrs before they get the chance. I know loads of pilots without their ATP that are well past 3000 hrs. Considering it is not uncommon for a regional pilot to get 600-900 hrs in a year, it as also a bit silly to mandate 1500 hrs anyway as they will exceed 1500 hrs fairly quickly anyway.
