Advisory Circulars

Transport Canada issues Advisory Circulars (ACs) to help the civil aviation community understand how to comply with current regulations and standards in aviation.

On this page

How the document series works

  1. ACs that relate to a part or standard of the Canadian Aviation Regulations (CARs) are found in the matching numerical series
    • Example: An AC on flight crew licensing related to CARs 401 will be posted in the 400 Series
  2. ACs that do not relate to one specific part or standard of the CARs are found in the 100 Series – General provisions
    • Example: An AC on safety management systems that applies to all aviation organizations will be posted in the 100 Series – General provisions
  3. ACs that do not relate to another regulatory instrument will be located in the applicable series
    • Example: An AC on employee health and safety will be found in the LTA Series – Labour travail aviation, otherwise known as aviation occupational health and safety
