Hello Harsh,

The age eligibility criteria for AFCAT is as such:

Flying Branch through AFCAT and NCC Special Entry : Age of aspirants must be between 20 and 24 years as of January 1, 2022. There is upper age relaxation form candidates having valid and current commercial pilot license issued by DGCA. The relaxation is till 26 years.

Ground Duty (Technical & Non-Technical) Branch : Aspirants must be between 20 and 26 years, as of January 1, 2022.

since you will turn 24 on 24th August 2022 and therefore you are eligible.

Hope this helps. All the best!
