  1. This course will enhance the user’s knowledge regarding the establishment of a civil aviation administration (CAA) by providing clear guidance to the users on the following LEG subareas: promulgation and amendment procedures; enforcement; empowerment of inspectors; ratification and implementation of Article 83B. Additionally, it will provide guidance to the users on the following ORG subareas: establishment of State civil aviation system and safety oversight functions and its resourcing; technical personnel qualification and training; technical guidance, tools and provisions of safety critical information.

  2. The target audience of the course are ICAO USOAP auditors and ICAO Coordinated Validation Mission (ICVM) Subject Matter Experts (SMEs), government officers, including all civil aviation administration (CAA) senior technical staff/ department heads (line managers), National Coordinators (NCMCs) and assistant NCMCs, State senior management, legal experts, managers from operators and service providers. 

  3. This training can be taken as a stand-alone course for those who want to increase their technical awareness regarding the establishment of an effective State safety oversight system, or can be taken by existing CBT users as a second qualification.

Course evaluation

Quiz questions provide a knowledge evaluation for each module, and two separate exams allow confirmation of knowledge and understanding of practical use of the course content, including mandatory reading materials.

The course is divided into 3 steps:
  1. An exam covering Parts 1, 2 and 3 will be conducted at the end of Part 3. Participants are required to obtain a minimum score of 70%. A retake is allowed twice if the score is below 70%.
  2. Upon successful passing of the exam pertaining to Parts 1, 2 and 3, participants will then proceed to a knowledge test on a specific audit area, which is a pre-test and will qualify them to take Part 4 of the course. Participants are required to obtain a minimum score of 80% on their knowledge test. A retake is allowed twice if the score is below 80%.
  3. A final exam will be conducted at the end of the specific audit area module in Part 4 of the course. A minimum score of 80% is required to successfully complete Part 4. A retake is allowed twice if the score is below 80%.

Note: For all of the 3 steps, upon non-completion of the course after 2 retakes, the candidate will be de-registered and may take the course again after a suggested time frame following the complete enrollment process (including the fees).
