Reading the ASA ATP studyquide and I'm reading this.
The pilot-in-command (PIC) of an air carrier flight must have had a proficiency check within the preceding 12 calendar months. In addition, within the preceding 6 calendar months the pilot-in-command must have either passed a proficiency check or completed an approved simulator training course.
Does the sim training course count as a proficiency check? I find this statement confusing.
