Under which subject number are FAA advisory circulars related to Airmen issued?

FAA advisory circulars related to Airmen are issued under subject number 60. This subject area encompasses guidelines and recommendations that pertain to the certification, training, and operational requirements for pilots and other airmen. The advisory circulars provide critical information that helps ensure safety and compliance with aviation regulations.

The choice of subject number 60 specifically addresses the various aspects of airmen's qualifications and performance, encompassing everything from training programs to flight proficiency standards. This structured approach ensures that airmen are well-informed and maintained to a high operational standard, thus enhancing overall aviation safety.

In contrast, subject numbers such as 70 or 90 cover other areas of aviation operations, such as air traffic control and flight rules, which are not solely focused on airmen. Subject number 100 is more relevant to general policies and procedures within the FAA but does not specifically address airmen's advisory requirements. Thus, subject number 60 is the correct classification for advisory circulars related to airmen.
