To answer what are the requirements to become a pilot the first step is fulfilling the educational and age criteria set by the Directorate General of Civil Aviation (DGCA) in India. You should have completed 10+2 (Class 12) or its equivalent. Traditionally you must have studied Physics and Mathematics at this level. Some institutions ask for minimum 50% in Physics & Maths but many now recommend 60% or more. The minimum age to apply for certain pilot training and licenses is 17-18 years. It's encouraging to know that recent reforms are gradually opening the path even for students from commerce or arts streams (via bridge courses) meaning the dream of a pilot career is becoming accessible to more young people.
Another critical requirement to become a pilot is medical fitness. You will need to get a Class 2 medical certificate initially, and then a Class 1 medical certificate to fly commercially. These assessments cover eyesight (often 6/6 or correctable to 6/6), hearing cardiovascular health overall physical fitness and no disqualifying medical conditions. The good news is: if you are healthy fit and maintain physical wellbeing this is absolutely achievable and a key step towards your pilot dream.
Once you've met educational and medical criteria the path moves into training. You must join a DGCA approved flying school or training organization. The typical sequence is:
Student Pilot Licence (SPL)
Private Pilot Licence (PPL)
Commercial Pilot Licence (CPL)
Ground school theory exams include subjects like Air Navigation Air Regulations Meteorology Aircraft Technical and more. You also need to build up flying hours for example around 200 hours or more of flying experience is common before obtaining CPL. You might then further get instrument ratings or multi-engine ratings depending on your airline goals.
Beyond the technical requirements you'll need to be proficient in English (spoken & written) since aviation globally uses English for communication. You also must be an Indian citizen or meet residency/citizenship requirements. Having a positive mindset discipline good decision making teamwork and commitment are part of the intangible requirements to become a pilot that help distinguish successful candidates.
