ITI Aeronautical Structure and Equipment Fitter Syllabus: Understanding the ITI syllabus is important for achieving high marks. The syllabus lists the topics for the semester exam, so it's essential to cover all areas of your trade and review them regularly. NCVT exams include the Craftsman Training Scheme (CTS), Apprentice Training Scheme (ATS), and All India Trade Test (AITT). The AITT and ATS tests take place each year in July and August, while the CTS exams are held in December.

The 2-year Aeronautical Structure and Equipment Fitter course is available at ITIs across the country. The syllabus consists of two main parts: the Domain area, which includes trade theory and practical skills, and the Core area, which focuses on employability and life skills. After completing the course, trainees receive a National Trade Certificate (NTC) from DGT, which is recognised worldwide.
