Yes the entrance pathways for becoming a civilian commercial pilot versus a defense pilot (e.g. in the Indian Air Force) are distinctly different in their structure administering bodies content process and eligibility criteria.
If you’re aiming for a Commercial Pilot License (CPL) after your 12th grade education you typically appear for entrance or aptitude assessments conducted by flying schools or centralized platforms such as PILOT CET (Pilot Common Entrance Test). These are tailored to evaluate your readiness for training in civilian aviation sectors. For instance PILOT CET requires PCM subjects in Class 12th has a specific online format, covers subjects like Physics Chemistry Mathematics English and General Awareness, and is administered thrice a year.
Alternatively many flying academies conduct their own basic aptitude and English proficiency tests to screen candidates for pilot training.
On the defense side particularly if your goal is to become a pilot in the Indian Air Force (IAF) you don’t appear for PILOT CET. Instead, you go through formal defense recruitment exams such as the National Defence Academy (NDA) Combined Defence Services Examination (CDSE) or the Air Force Common Admission Test (AFCAT) depending on your age educational level and entry scheme.
For example AFCAT is used to recruit for flying branches and is conducted in two stages a written test followed by further selection processes like the Air Force Selection Board assessments.
Additionally after passing these initial exams candidates must undergo specialized aptitude testing such as the Computerised Pilot Selection System (CPSS) an advanced screening mechanism developed specifically for selecting fighter and transport pilots for the IAF
